IT Security Planning & Implementation
Information systems have always been complex over their existence. The same has been true of securing those networks and systems. However, with the growing complexity and capabilities of these machines and networks, the security implications and possibilities of just what level of depravity that hackers will stoop to. This report shall explain the basics of information technology equipment and security as well as the threats that exist to the same. These threats include worms, viruses, Trojans, spyware, adware, zero-day attacks, hacker attacks, denial of service attacks and data interception or theft.

Typical computer networks are made up of a series of workstations and other devices. The devices that might exist are workstations, servers, printers, firewalls, switches and routers. The different pieces of equipment that exist might or might not be network-enabled or even capable of networking at all. Some devices only communicate through USB while others can…

Data destruction is when an attacker goes in and starts deleting things (Curtin, 1997).
There are a number of ways that a company's network can get attacked. One being if you have a single component to provide security, an attacker only has that one thing to get around in order to gaining full control of your system. Also not having secure modems can give access to unwanted attacks. However, these are evolving every single day. The first one being shortened ULs, a Shortened UL nickname can be handy, but pose risks. Since they give no hint of the destination, attackers can exploit them to send you to malicious sites. Then it discusses data harvesting of your profile. This is when an attacker collects enough information to access your sensitive accounts. They do this by the information you share on social networks, such as your high school, hometown, or birthday, which…

Network Security This report is the answer to a scenario that was provided as the basis for this assignment. The idea is that a security firm has been awarded a contract for a local government agency. As part of that contract, the author is being asked to provide a number of deliverables. These would include an information flow diagram, an equipment list that would be required so as to make up the network security infrastructure, a maintenance plan to keep the network running and operating in optimal fashion, a list of at least four security measures that could be developed, two physical security vendors that could be used and how human resources could and should figure into all of the above. While there are multiple ways to undergo a network security system plan, there are some options and paths that are more required than others.

Network Security: Past, Present and Future
The work of Curtin (2007) states that a network is defined as "any set of interlinking lines resembling a net, a network of roads -- an interconnected system, a network of alliances." Quite simply a computer network is a system of computers that are interconnected. There are seven layers of communication types identified by the International Standards Organization (ISO) Open Systems Interconnect (OSI) eference Model as well as the interfaces among them. Each layer is stated to be dependent on the services that the layer above it provides including the physical network hardware.

Technology: Description and Area of esearch

The most popular networks which have been used over the past twenty-five years and which include both private and public networks include the following network services: (1) UUCP -- Unix-to-Unix CoPy: This was developed originally for connecting Unix hosts together however, since that time UUCP is reported to…

Conclusion

The purpose of this discussion was to examine the network security measures that are available. The research found that the proper configuration provides the first line of defense as it relates to securing a network.

In addition, firewalls serve an essential role in securing networks against outside intrusions. The research also indicates that anti-virus software, encryption software and biometrics allow organizations to secure networks in a more comprehensive manner. There are also specific strategies and technologies that should be considered if an organization chooses to use a wireless network.

The main lesson learned from viewing the tutorials and programs is the ease and flexibility of configuring each specific session to the unique needs of an audience. Feasibly these technologies could be used for creating highly unique and tailored learning experiences for students who were learning through online universities only for example. The ability to tailor all forms of digital content, from music and video to drawing boards and the inclusion of self-pacing materials, shows the potential of these technologies to support online learning over an entire semester for example (Suduc, Bizoi, Filip, 2009). The implications on long-term learning using these technologies is also significant. It is clear that the recursive nature of how they are designed would allow for repetitive study of complex concepts, including the more challenging areas of math, statistics and the sciences.

Network Security: An Issue for Business Data Communication
Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time.

The key security issue facing IT professionals is to protect the system from invaders or intruders known as Hackers. Hackers can be grouped into several categories according to motive. They are Joyriders (who do it for fun), Vandals (who do it to cause harm), Scorekeepers (who…

Networks are continually vulnerable to threats, which is why it is important to understand the ramifications of ping sweeps and port scans. While ping sweeps and port scans are not attacks in and of themselves, they are probing activities. Ping sweeps are automated processes that show the malicious user which computers on a network are active, whereas port scans identify the potential points of entry into a network from which to launch an attack. Both ping sweeps and port scans are threats that can be averted in order to protect network security.
Ping sweeps are akin to shouting aloud in a canyon and waiting for a response, or sending a call on a radio. Usually, intruders can create robots to conduct ping sweeps for them. One protocol used is the ICMP ECHO (Teo, 2000). The ICMP ECHO sends messages within a range of IP addresses. Another type of ping sweep is…

The paper will provide a better insight on the general aspects of security and also get a better understanding of how to be able to reduce and manage risk personally at the workplace and at home.
In today's world, the Computer has become a common feature in any organization anywhere in the world. This may be due to the fact that a computer can be accessed by anybody who knows how to handle it and also because it can store a lot of information both confidential and general. A computer is connected through a physical network that allows a person or many persons to share any information necessary.

Best Practice Wireless Network Security
Best Practices for Network Security

Wireless network is a technology that relies on radio waves instead of wires in connecting computer devices to the internet. There is a transmitter, with the name wireless access point or gateway, wired into an internet connection, which provides a "hotspot" transmitting the connectivity over radio waves. Hotspot has the capability to identify information, that include an item known as an SSID (service set identifier), that enable computer devices to locate them. For computer and other devices that have been equipped with wireless card as well as have permission to access the wireless frequency can then have the opportunity to connect to the network. There are some computer and other devices that may be able to automatically identify open wireless networks within a particular area, and for some you may be required to locate and enter the information manually like the SSID.

Network Security Administrator, Approach Problem Securing a Central
I would utilize a number of security measures to adequately secure a central computer network that is accessed by other branches and staff from remote physical location. The vast majority tends to work in conjunction with one another, and should not deny access to authorized users.

For all of the computers that are present in the primary, physical location in which the network is based out of, I would employ encryption measures. This sort of encryption is similar to that used by cellular devices (whether in the form of tablets or phones), which enables users to reduce the threat of unauthorized users from accessing their devices or the data within them (Stafford, 2010). However, it is worth noting that encryption would not be used on the computing devices in the network that are outside of this primary physical location.

One of the primary layers…

Bejtlich's insights and outlooks when it comes to many different areas of network security monitoring really helped to provide the necessary context for understanding the material, mechanisms, and processes of the field.
There were other readings assigned in the course that were useful, too, of course, and many other sources encountered during the various exercises and research/written work required for the completion of the course that were also beneficial in identifying and illuminating many of the specific areas of concern and of growing knowledge and interest in the network security monitoring field. While Bejtlich (2004) does a tremendous job of introducing and outlining many of the fundamental theories and frameworks within the discipline of network security monitoring, these other sources were also enormously useful in their further commentary on these issues and in the different perspectives that were brought to bear on such things as end-user security, the nature of…

Cisco SAFE

Cisco SAFE has significantly help in securing large internetwork that has remain a daunting challenge; this complexity has been facilitated through cloud computing as well as social networks. Cisco SAFE architecture offer guidelines of design and implementation which are detailed that is used for building secure and reliable network infrastructures as well as the policies supporting them. The guides have been established based on security best practices that have been amalgamated with several hours spent in designing, testing, and documentation.

Since the contemporary organizational environment is full of threats, the target is directed on everything and Cisco SAFE uses defense-in-depth approach to provide the needed security. Systemwide intelligence approach for SAFE tend to address network devices; security of the infrastructure, applications and application servers; endpoints; email; web; databases; storage systems; communications devices; and other servers. This is accomplished through putting emphasis on the integration of…

Telecommunication Proposal

Network Configuration Management Plan

In order to meet the needs of the customers, ABC Inc. must insure that productivity is not hindered by the growth of the company. The employees at ABC Inc. must have a robust network so that customer service is not jeopardized. The accounting firm has grown from five to fifty employees with the acquisition of a large account. Currently, each employee has their own standalone computer which contains Windows 7, Office 2010 and QuickBooks accounting software. The company does not have a network in place. Currently information is shared by copying data to a flash drive and each workstation has a stand-alone printer. The objective of this proposal is to provide a centralized solution for all of ABC's network needs.

Given the highly mobile aspects of the company's workforce, it is recommended…

All network authorized personnel must be instructed to use "strong" passwords consisting of at least 8 characters; they must include at least one upper and one lower case letter, at least one Arabic number, and at least one "special character" in addition to avoiding any form or abbreviation of the user's first or last name (Boyce, 2002; Kizza, 2005).
Network administrators must also implement applications capable of ensuring compliance by automatically rejecting improper password choices. Additionally, administrators must require authorized users to change their passwords at specific intervals. Finally, office managers must monitor compliance with common-sense rules about behavioral aspects of password security, such as prohibiting divulging passwords to co-workers, requiring users to log off if they leave their terminals, and by providing training into recognizing attempted social engineering to obtain secure information through deception (Larson, 2007).

Likewise, authentication layers can also significantly enhance network security. In that regard, the most…

The behavior of both botnets and worms in peer-to-peer networks have been empirically examined and models or simulations of their behavior have been attempted, and the manner in which different nodes in peer-to-peer networks develop in and of themselves and in terms of their relationships with other nodes -- the very architecture of the network itself, in other words, which is necessarily dynamic in a peer-to-peer network -- makes it easier for these threats to spread and evolve undetected due to this architecture and to the patterns of information flow over such networks (Fan, 2011; Xu et al., 2011). When it comes to worms propagating in peer-to-eer networks, the activity of the worm itself has been demonstrated to be the most necessary knowledge in terms of tracking and preventing the continued spread and damage of such a threat, while botnets generally show more "robustness" an are better impacted by…

ABC School Stats/User Counts

Having a current strength of approximately 845 students, ABC School provides education from Pre-Kindergarten to the 12th Grade. According to the requirements of The New York School District, 250 Curriculum computers along with 75 Administration computers are to be installed. The requirements for the wiring per room of layer 1 are that it should adjust a total of 25 computers, 24 of which will be used for the curriculum, whereas one will be used for administrative purposes.

The responses to a network security monitoring attack needs to be based on an assessment of the method of the attack that is being leveled against the network and its security monitoring, and thus can be as varied and complex as the attacks themselves (Bejtlich, 2004). Two tactics or tools that an attacker might use to attack network security monitoring are an attack from a stepping stone or an attacking using a spoofed source address. Both of these are methods by which the attacker uses tools and processes to hide their location and identity, making it more difficult to trace the origin of the malicious activity and thus to end it and also causing problems when it comes to the legal end of proving and prosecuting crimes. There are numerous methods of addressing attacks that utilize such tools, including different ways of attempting to track the true and hidden…

The company should use the Cisco hedge router to make the company to achieve a reliable communication over the internet. The edge router will also make the company to achieve higher capacity, scalability, and improve routing protocol convergence at lower costs. As traffic volume increases, the solution will allow the company to implement incremental bandwidth upgrades without necessarily changing the router interface. The edge firewall will be used to protect the network from the unwanted traffic. The firewall will also be responsible to enforce the internet access policy. As an added security policy, the company should also use the Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) to detect and prevent unwanted traffic into the network.

Network Management and System Administration
The aim of the paper is to establish the difference between a system administrator and a network administrator. The paper is thus divided into three sections. The first section deals with the basic definition and responsibilities of a system administrator; the second does the same for a network administrator and the third compares their responsibilities to clearly identify the differences between the two.

System Administrator

The maintenance of computer systems in a company is the sole responsibility of a system administrator. They are responsible for maintaining, upgrading and installing servers. They are also entrusted with the task of checking the security of the server and maintaining its backup as well. They are also involved in programming for automating tasks at the server. For this purpose, they write programs, also known as scripting (Schneider, 2012a).

Education criteria for System Administrators:

With respect to the level of qualification, mostly system administrators do…

). Such security should also preplan strategic responses to attacks associated with the network (Dawkins et al.).
A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained between the firewall and the internet access or between the firewall and the internal network are often vulnerable. Organizations with networks should work hard to secure them at these points. The article also states that if attackers can gain access to a network at these points, they can gain access to sensitive information and compromise the stability of the network. Also attackers who gain access to a network at one of the aforementioned points will also be able to develop…

Network Vulnerabilities and Controls
Computer networks are constantly under threat from many different sources of attacks. In order to get a clear understanding of the different views on computer security and its characteristics, it is important to define a network. This term means a group of computers that have been interconnected to communicate to one another using electrical signals. The network can be either wired or wireless and the most common of them nowadays is the wireless computer network. The internet or wide area network can link very many computers that are widely and geographically apart.

Computers are therefore linked to communicate with one another via the internet. However, these same computers are prone to attacks from all different angles. Any unauthorized access to ones computer can be defined as an attack since in the process, valuable information may be retrieved from the computer or even deleted. The information may be defined…

Security and Baseline Anomalies
Base lining is the performance of measuring and evaluation the presentation of a network in instantaneous situations. Provision of a network baseline calls for quizzing and reporting of physical connectivity, throughout the range of network usage. Such in-detailed network scrutiny is required in identifying problems associated with speed, accessibility, and finding vulnerabilities within the network. Predefined security settings are put in place to manage large security networks. These settings can be applied on a number of similar computers in a network. Settings and templates helps to reduce the occurrence of errors and omissions and this also helps in securing the servers.

How to obtain a baseline system

A baseline system of network behavior can be obtained through sub-netting a network. This entails dividing a network into smaller networks through a series of routers. Routers help to improve the security of the sub-nets by regulating the users within the network…

Network Standards
A Brief Look Since 1995

This is a research paper that focuses on network standards and protocols that involve strategies in management. Leadership strategies cannot handle the need for network standards to handle billions of users and user generated applications. Therefore management strategies are more appropriate. Furthermore the history of network standards shows layering through the OSI models follows a management approach vs. A leadership approach.

In the OSI model, there are seven layers. The seven layers then acts as a means of managing problems within that layer as it is separated and contained. People can run communication through these layers much more easily and smoothly than through a singular, whole layer. The several layers are more efficient and can handle and spot problems and inefficiencies more quickly. It serves as the basis for network standards.

The history behind network standards provides valuable insight into how organizations emerged to deal with the…

Security eport
In the present day, organizations are reliant on information in order to continue being relevant and not become obsolete. To be specific, organizations are reliant on the controls and systems that have been instituted in place, which provide the continuing privacy, veracity, and accessibility of their data and information (Lomprey, 2008). There is an increase and rise in threats to information contained within organizations and information systems (Lomprey, 2008). There is also a rise in the intricacy of such systems and information, which places emphasis on the importance for organizations to understand and gain an understanding of how to better safeguard their information as well as information systems. As stated by Briggs (2005), globalization has instigated the world to become a global village. This, in turn, has increased the level of complexity and intricacy of the information security aspect of the organizations across the world. There is greater need…

(%) Cross Site Scripting (XSS) errors -- by far the most common strategy hackers use to gain access to the source code of websites and the databases supporting them is to use a technique called cross-site scripting (Brodkin, 2007). Actively monitoring the percentage of XSS errors over time can determine patterns of when hackers attempt to gain access to a website's source code, database links, pricing and e-commerce systems. This is one of the most often used metrics in security dashboards used for monitoring Web-based applications and multisite installations.

(%) Incidence and Trending of Buffer Overflow Injection Flaws -- This is most commonly associated with attempts to gain access to SQL databases supporting a website by forcing a buffer overflow condition (Brodkin, 2007). This is one of the most effective hacking strategies there are as it forces a system to fail and allow access.

Security Audit for FX Hospital EH/EM Systems
The study carries out the security audits for the FX Hospital EH/EM information systems to identify the vulnerabilities in the systems. The study uses the BackTrack as an auditing tool to penetrate the website, and outcomes of the auditing reveal that the website is not secure and can be subject to different vulnerabilities. After carrying out the auditing, the study is able to collect as much patients' data as possible revealing the website can be subject to vulnerable attacks. One of the vulnerabilities identified is that the website UL starts from HTTP showing that an attacker can easily break into the website and collect sensitive information. Moreover, all the data in the website are not encrypted making them easy for an attacker to collect patients' data.

By consequence, the FX Hospital can face lawsuits for failing to protect patients' data because if patients' data are…

In less than one hundred years, air travel and networking and computing communications have evolved from the Wright brothers and the UNIVAC housed in several huge rooms to fully functional in-flight Gulfstream network communications. Passengers today expect their palm pilots, laptops and PC's to work as seamlessly as the flight itself. The modern day concerns are mired in the fact that digital conversation now entails a two way link that has inadvertently opened up a can of worms for airline network administrators. Network security and key distribution and management authenticating and authorizing ad-hoc networks have taken on new meaning in the realm of personal aircraft.

Network Implementation for Davis Networks Inc.
In the proposal, effort is made to develop an affordable local LAN for Davis Networks Inc. The effort involves provision of wireless Internet connection to all individuals for their desktops and laptops from the current high speed connection they have at an affordable price (800 USD -- 1000 USD). Provision of the internet to the same location costs approximately 700 USD including all other expenses like doing the wiring etc. To implement the project, there are various obstacles that have to be considered like electric poles, trees and walls. The core location is the Computer Center building. It has the highest speeds of connection. From this building, there will be distribution to the surrounding buildings located between 500 and 1000 meter range.

Examples are 10BaseT ethernet and 100VB AnyLAN networks. I would devise an intelligent hub that would have enhanced capacities for other features such as remote management capability.
Switches are an addition o hubs and would also provide this prospective network with support capacities such as multiple bandwidths, bridge functionality, and router functionality.

I will install a bridge that will filter data packets according to their various addresses. This will forward only the appropriate packages to the relent address. The packet moves on if it does not belong. This function seperates the various files and ensures that each receives its correct one without clogging up the system. It also provides data security so that each receives only that which he is permitted to have access to. Bridges help th traffic. They require, however, that network managers install and update their list of addresses.

Routers are also an inescapable piece of my network. The…

Wireless and Wi-Fi

The dominant approach used today for connecting to network, wireless technologies including W-Fi is dominating the entire area of networking, from 3G and 4G on smartphones and tablet PCs to the development of hotspot technology on the attest iPad. This is the future of networking for many consumers. The reliance on Wi-Fi as a means to stay connected to business and friends has exponentially increased and will continue to for the long-term (Gilmer, 2010). The fundamentals of Wi-Fi are easily taught as they are based on IEEE standards that create a framework for teaching these technologies with clarity and insight (Greiner, 2001). Wi-Fi continues to increase in terms of speed as well, with 3G and 4G now commonplace. Consumers need to know about this technology and how it works to troubleshoot problems on their smartphones, tablet PCs and laptops. The best approach to managing the teaching process is…

" (Muntenu, 2004)
According to Muntenu (2004) "It is almost impossible for a security analyst with only technical background to quantify security risk for intangible assets. He can perform a quantitative or qualitative evaluation using dedicated software to improve the security of the information systems, but not a complete risk assessment for the whole information system. Qualitative assessment based on questionnaires use in fact statistical quantitative methods to obtain results. Statistical estimation represents the basis for quantitative models." Muntenu states conclusion that in each of these approaches the "moral hazard of the analyst has influence on the results because human nature is subjective. He must use a sliding window approach according to business and information systems features, balancing from qualitative to quantitative assessment." (2004) qualitative study of information systems security is reported in a study conducted in U.S. academic institutions in the work of Steffani a. urd, Principal Investigator for Information…

Security Technology in Next Five Years
Globally security concerns have placed great pressure on the survival of human life and had threatened the daily life, confidence and dignity of societies at large. To resolve the security concerns and overcome with this disastrous obstacles, security technological advancements have been made in many facets. Human life is playing its vital role in moving the world to a secure place where families, businesses, trade, educational system, media, governance, art and science thus all fields of life is affected by the security concerns (Sen, 2002). Now the big question here is how technological development can contribute towards the security concerns especially in the areas of biometrics, forensics and physical security.

Although, there has been intensive increase in human security as the consequences of technological development, the historical background of technology has not rooted much confidence in the societies that further technological development will reduce the…

After server authorization four domains for giving and registration of addresses of clients are created. "If a physical LAN has more than one logical subnet, how can different groups of clients be allocated addresses on different subnets?
One way to do this is to preconfigure each client with information about what group it belongs to. A DHCP feature designed for this is the user class option. To do this, the client software must allow the user class option to be preconfigured and the server software must support its use to control which pool a client's address is allocated from. (DHCP FAQ (http://www.dhcp-handbook.com/dhcp_faq.html#iaplh)

In order to create domain, wizard is used. In nets 208.32.16.0, 208.32.16.64, 208.32.16.128 elimination range is used only from one (last) address of range, because it's assigned to router's port as it was mentioned above. All other nodes, including printers may be set up on automatic receiving of address…

There is a trade-off with regard to this first layer to ensure a high level of physical security that does not compromise the system-level flexibility and support. This first level of support can be as simple as locks, fireproofing and safes to biometrically based access as well. The components of physical security are surveillance and notification systems. These are systems that react to smoke, intrusion or a threat in the form of a break-in for example. Using motion sensors, intrusion detection equipment and closed-circuit televisions are all part of this step, as are continual centralized monitoring of the entire site as well. Organizations have successfully been able to integrate emergency self-start shutdown procedures for systems when intruders are discovered, disabling all system access to protect the data. A third class or component of security is the reliance on combining physical monitoring systems with the actual enterprise systems to ensure…

The greater the employee ownership and vested interest in a program's success, the greater the probability of its success. This emanates from a leader's choosing to endorse and actively support an information security program and show consistency of effort and focus to attain tis objectives (Madnick, 1978).
A third critical success factors is the providing of periodic feedback as to the progress of the information security program. The ability to actively monitor an information security program's progress using analytics and metrics of performance will significantly increase the likelihood of continued support (Straub, Welke, 1998). As is the case with many change management initiatives, the use of analytics and metrics also provide feedback to the employees and leadership of an organization, reinforcing adoption to the information security program over time (Guttman, Herzog, 2005).

Conclusion

The basis of effective change management is predicated on giving employees the ability to attain autonomy of their jobs,…

Information System Security Plan
The information security system is required to ensure the security of the business process and make the confidential data of the organization secure. The organization's management is required to analyze the appropriate system to be implemented and evaluate the service provided on the basis of their required needs. The implementation of the system requires the compliance of organizational policies with the service provider to ensure the maximum efficiency of the system. The continuous update and maintenance of the system is required to ensure the invulnerability of the system towards the potential internal and external threats.

This type of firewall operates by relying as an relaying agent that exists between the external and internal hosts (Stephen, 2004). The whole idea is to protect the network's internal hosts from direct exposure to the outside environments.

The CPF firewall operates by accepting various requests from the internal hosts for the sake of establishing the connection to the external world. It then destroys the device's initial IP address as well as the header of the network layer.

Disadvantages of CPF

Network Security and Why Use It
Security And Why Use It

The security of any network should be taken seriously. A network allows someone to share resources and information with others on the network. Networks allow for distribution of computer viruses, Trojans, human intruders, and employees can damage more than just one computer. To better understand the importance of network security, one needs to think of what might happen if all the data for a company that is stored in their servers vanishes. This scenario would cause losses that the company might never recover. Networks are divided into three main categories Internetwork (internet), Wide Area Networks (WAN) and Local Area Networks (LAN). These three categories of network require security to ensure that no malicious humans gain access, and no viruses attack the network.

To better understand network security, one needs to know what a network is. A network is defined by Hu, Myers,…

Security of the IT network for any company is very important. Scores of sensitive business information is stored electronically in the IT systems and the company network. An unsecured or a partially secured network has the potential to cause financial losses to the company if the information falls in the wrong hands. Therefore there is need for installing and network security systems.

For any network security to become operational the company must first look into whether the system can be implemented technically and whether it can be implemented throughout the organization. Another consideration for the selection of the network security is to ensure that the system clearly define areas of responsibility for the users, administrators, and management and is flexible and adaptable to the changing…

Identity Management and Security Awareness Training Plan Strategy

all departments.

Duration and frequency: three sessions of one hour each. Technology developments that are used in permanently updating the company's security features must be communicated to employees. Update training sessions of two hours must be performed every three months in order to keep up with technology improvements.

The training program must inform employees on the company's security guidelines. The administrative, technical, or physical safeguards intended to protect the personal information of clients and employees must be communicated and explained to all department members. In addition to this, the company must identify current attitudes towards information security that employees have (Winkler & Manke, 2013). The training material will be structured in accordance with these attitudes.

Trainer selection:

In this case, the question is whether to select an in-house or an outside trainer. An outside trainer could have more experience on security awareness and better training skills.…

Network Design
The process of gathering technical requirements for a network design project may differ from one organization to another, but the requirements themselves can be described using many of the concepts discussed in the lecture this week (i.e. Scalability, Availability, Network performance, Security, Manageability, and Affordability).

Analyzing technical requirements for the customer is important in helping one best fulfill the customer's expectations. The various objectives that need to be fulfilled involve the factors of Scalability, Availability, Network performance, Security, Manageability, and Affordability.

Scalability

Scalability refers to the amount of growth that a network design can support. This is particularly important for large companies that are adding users, applications, additional sites, and external network connections all the time. The proposed network deign should be able to adapt to any envisioned additions. You will want to know the prospective amount of networks, users, servers, and/or sites that may be added to the network within the…

Another aspect of the security management area of a network management system is the development of policy-based auditing and alerts by role in the organization
(Merilainen, Lemmetyinen, 2011). This is one of the areas of knowledge-enabled security management, specifically in the area of role-based access and advanced auditing and reporting.

Fault management is also an area that no single suite of network management systems can completely meet per the ISO standards today. This requires the CIO and network managers to define specific goals in this area including the extent of fail-over support and use of advanced fault tolerance technologies (Netak, Kiwelekar, 2006). Accounting management baseline performance includes the ability to generate logs of performance and also define benchmarks for performance. This is the minimal level of functionality a CIO and network manager need to consider when selecting a network management system. Configuration management systems requirements range from the relatively simplistic definition…

During the PDIOO procedure one has to define main deliverables and related actions with a direct connection to the additional value and advantage for the customer network. For instance, understanding business objectives, usage features, and network necessitieshelps a person avoid pointlesselevations and network redesigns, thus reducing the time taken to introduce fresh services in the network.
Planning Phase

During the planning period one can test the significance of the design for future complications. Planning assists in avoiding repeating a logical faultwhen dealing with a network design that a might person uses as a template in various locations.The planning phase concentrates on technical and financial criteria and considers all the necessities and constraints discussed (Asakura & Kashiwadani 2003).During this stage, it is significant to recognize all the stakeholders to make theprocedure a success. The stakeholders are individuals or organizations who have entrusted interest in the environment, enactment, and result of the project.

Q3. Discuss the internet of things and its likely consequences for developing an enforceable information assurance (IA) policy and implementing robust security architecture.

The internet of things refers to the inevitable connectedness of all things in all regions of the world through the internet. "The fact that there will be a global system of interconnected computer networks, sensors, actuators, and devices all using the internet protocol holds so much potential to change our lives that it is often referred to as the internet's next generation" (Ferber 2013). Although the internet feels ubiquitous today, the internet of things refers to an even more complete merger of the virtual and the real world. "In many and diverse sectors of the global economy, new web-based business models being hatched for the internet of things are bringing together market players who previously had no business dealings with each other. Through partnerships and…

Network/IT Communications
Selecting the type of cable to be used when developing a LAN from the ground up can be a complex process with many considerations, including issues of functionality and of cost. Twisted pair cables provide a cheaper alternative to other cable types and are also the most flexible type of cable, but they are less secure and are more prone to losses in data integrity than are other standard cable types (Hsieh, 2012). Fiber optic cables provide the best protection against interference and are the most secure cable for use in a network, but the cost can be prohibitive and the heightened performance aspects are not necessary in all applications (Hsieh, 2012). Coaxial cables come in two varieties, thinnet and thicknet, with thinnet being both cheaper and more flexible than twisted pair cables (though still more expensive and less flexible) and also provide a decent amount of security and…

This researcher rejects the existence of online communities because computer mediated group discussions cannot possibly meet this definition. Weinreich's view is that anyone with even a basic knowledge of sociology understands that information exchange in no way constitutes a community.
For a cyber-place with an associated computer mediated group to be labeled as a virtual settlement it is necessary for it to meet a minimum set of conditions. These are: (1) a minimum level of interactivity; (2) a variety of communicators; (3) a minimum level of sustained membership; and (4) a virtual common-public-space where a significant portion of interactive computer mediated groups occur (Weinreich, 1997). The notion of interactivity will be shown to be central to virtual settlements. Further, it will be shown that virtual settlements can be defined as a cyber-place that is symbolically delineated by topic of interest and within which a significant proportion of interrelated interactive computer…

To offer an information security awareness training curriculum framework to promote consistency across government (15).

Security awareness is needed to ensure the overall security of the information infrastructure. Security awareness programs is the can help organizations communicate their security information policies, as well as tips for users, to help keep systems secure, and the practices the entire organization should be utilizing. However, as Kolb and Abdullah reiterate, "security awareness is not about training but rather designed to change employee behavior" (105).

A program concerning security awareness should work in conjunction with the information technology software and hardware JCS utilizes. In this way, it mitigates the risks and threats to the organization. Security awareness is a defensive layer to the information system's overall security structure. Although not a training program, per se, security awareness does provide education to the end users at JCS, regarding the information security threats the organization faces, and the…

The most appropriate products that could be used by MMC to achieve this objective would be: IP San and a Snap Lock. An IP San is a fiber optic channel that can provide secure real time data to each location. Where, software and security applications can be adapted to the current system that is being used. The Snap Lock is: a security software that can be used to provide an effective way for each location to retrieve, update and change information.
Support for why these procedures and products are the optimal approach for this organization

The reason why these different procedures and products were selected was: to reduce the overall risk exposure of the company's external threats. The current system that is being used by MMC increases risks dramatically, by having a number of different systems, where financial information is stored. If any one of these systems is vulnerable, there is…

Evaluating the Advantages and Disadvantages

of Using Cloud-Based Systems for IT Storage and Applications

The emergence of cloud computing as a disruptive innovation is redefining the economics of information technologies, application delivery and the pace of new feature development and introduction. Companies who are standardizing on cloud computing for critical tasks including Customer elationship Management (CM) do so after evaluating several factors, including the opportunity to expense the costs vs. pay for them via capital expense, the customization of the applications, and the ability to selectively update them over time (Lashar, 2009). Cloud-based applications delivered over Software-as-a-Service (SaaS) platforms are paid for as an operating expense, which is often referred to as OPEX. Traditional enterprise software is paid for through CAPEX, or capital expense investment. This is a critical point in the economics of this market and a primary criterion that TUI University needs to consider was it evaluates using a…

Segmentation of tasks distinctively: It depends on the principle of drive and conquers. It involves brainstorming about the organization's security tasks in terms of pieces and separating them into logically and physically segments. For instance, security tasks depend on ensuring people are kept on the outside by using both physical and firewall security (Bergmann & Pamplin, 2013). However, other components are safely kept on the inside using antivirus. Security does not solely imply that people should be kept from the outside. Obviously, companies have lost information from within the business. In this case, each piece must be documented and prioritized.

During this process, is when they will learn about possible warning signs and how to deal with these threats. This will help to improve monitoring and it will increase the ability to quickly identify threats while they are small. (Cole, 2006, pp. 3- 48)
Step 4: Continuous monitoring. In this step there will be a focus on watching for any kind of threats. This is when a series of red flags will be used to identify and isolate threats early. If this kind of approach is utilized, it will help to minimize security breaches and their impact on the firm. (Cole, 2006, pp. 3- 48)

" (Harman, Flite, and ond, 2012) the key to the preservation of confidentiality is "making sure that only authorized individuals have access to that information. The process of controlling access -- limiting who can see what -- begins with authorizing users." (Harman, Flite, and ond, 2012) Employers are held accountable under the HIPAA Privacy and Security Rules for their employee's actions. The federal agency that holds responsibility for the development of information security guidelines is the National Institute of Standards and Technology (NIST). NIST further defines information security as "the preservation of data confidentiality, integrity, availability" stated to be commonly referred to as "the CIA triad." (Harman, Flite, and ond, 2012)

This leaves those clients that are inside unsupervised while the guard is outside. There is also a lack of signage inside displaying rules and regulations along with directions. This propagates a lot of unnecessary questions being asked of the surety officer on duty. In order to alleviate these issues it would be essential to place distinct parking signage outside in order to help facilitate clients parking in the correct spaces. It is also necessary to place directional signage within the facility along with general rules and policies. All of these signs together would cost approximately $1,000 to install.
The last security issue that needs to be addressed is that of the security information processes that is in place. As each client arrives at the facility, their license plate numbers are recorded and they are then assigned a number. They are seen by the appropriate medical personnel based upon the order…
