Firewalls: Great Network Security Devices, but Not a "Silver Bullet" Solution
In construction, a firewall is a hardened divider between the hostile external environment outside and what needs to be protected inside. Similarly, firewalls are designed to protect computers from being accessed by unauthorized individuals, and for the most part, they perform this task well. Unfortunately, firewalls are also akin to the castles of old when siege weapons were built to defeat the highest walls. As the siege weapons became more powerful, the defenders were forced to build the walls yet higher and install moats and other protective measures. Similarly, today, hackers and so-called crackers are always trying to overcome security devices for profit, pleasure or for more nefarious purposes such as denial of service attacks by terrorist organizations. To gain some fresh insights in this area, this paper presents a review of the relevant scholarly and peer-reviewed literature concerning…… [Read More]
Which Products are Best Suited to a Small LAN With One Publicly Accessible Web Site:
Cisco PIX Firewall Software is an excellent solution for small LANs with one publicly accessible web site. "Integrated Cisco PIX firewall hardware and software delivers full stateful firewall protection and IP Security (IPSec) VPN capabilities, allowing (...) rigorous (protection of...) internal network from outside intrusions" ("Cisco PIX," 2005). Cisco PIX firewall differs from typical CPU-intensive full-time proxy servers in that it uses a non-UNIX secure, real-time, embedded system, which is not only flexible but scalable as well. Cisco PIX offers protection for networks of all sizes. It "delivers robust user and application policy enforcement, multi-vector attack protection, and secure connectivity services in cost-effective, easy-to-deploy solutions" ("Cisco PIX 500," 2005).

Firewall to Protect Companies
A firewall is used to protect a person or business' network from exterior harms. Firewall may use packet filtering, user or client application authentication in order to protect the network. The actual process of protecting a network requires a firewall to filter incoming packet sizes, source IP address, protocol, and destination port. Administrators of a network are able to enact firewall protection on a router and this is often the first level of protection the network has against harm.
Along with being a primary protection, firewalls in routers are also beneficial to those not skilled or knowledgeable in firewall protection. Customers are able to install the firewall between their network and external internet connection on their own without assistance. Router-based firewall offers ease to those who use it and is used as a primary source of protection. Overall, it is far more practical to implement a…… [Read More]
Cyber security tendencies have evolved into systems that are used for data security, mostly for big corporations which can afford the service. System vulnerability is one of the major concerns of organizations getting web servers, firewalls and security measures for their data. Technology companies burn the midnight oil trying to provide the highest level of security to databases, and a breach of security can be deemed a lapse by the technology company or that their security measures being ineffective. Hackers might send unauthorized packets of data including network inhibitors that might stall the ABC servers which contain online payment processing and customer data.
The best firewall recommended for this system is the next-generation system equipped with sophisticated security protocols for the deployment in the ABC system. It combines traditional firewall with other network devices that filter unauthorized network protocols. In a distributed system where traffic is passed through different nodes,…… [Read More]
Once upon a time a firewall was a physical barrier that kept a literal fire from spreading from one building to another. Now the term is more often used to refer to a variety of devices - both hardware and software - meant to keep information from being stolen from a computer. This paper examines the variety of commercial firewalls that are available today.
Initially firewalls were separate pieces of hardware; this is becoming less and less the case in part because firewalls are now more frequently installed on home computers as well as on business ones, and many users of computers at home either do not have the space for or the expertise for a hardware firewall, which has given rise to the two varieties:
firewall is a piece of hardware or software that places a barrier between your network and the Internet. It prevents outsiders from accessing…… [Read More]
This is problematic, as these kinds of issues could lead to wide spread disruptions with no one knowing or understanding where it came from. For example, if a terrorist group was able to master this tool, they could utilize it to attack Western power grids. (Magnuson, 2013)
This would create significant amounts of disruptions without having anyone being able to trace what is happening directly. When this occurs, there is a realistic possibility that they could shutdown the economy and disrupt trade for significant amounts of time. These kinds of scenarios are becoming more realistic with this tool being readily available over the Internet. (Magnuson, 2013)
In other cases, this application could be used to attack a cloud network and gain access to large amounts of data. This information will help criminal groups to obtain entire profiles on people and organizations. They have the option of going to various institutions…… [Read More]
Exposing Your Data on the Internet
While I do not know someone who has personally been violated by the process of data mining, I recognize the potential danger in the process of collecting data for purposes like marketing. On the surface, data mining is harmless. Organizations or interested individuals simply collect and sort through data. Usually the purpose of data mining is "to identify patterns and establish relationships," such as the relationships between demographic features and consumer behavior or voting patterns (ouse, n.d.). Some of the potential uses of data mining include the identification of patterns of behavior in one individual or a group, classification of patterns, forecasting, and clustering (ouse, n.d.). The interesting thing about data mining is that the information does not have to be personalized, which is why data mining is legal and not even considered unethical in many cases. However, data mining can be personal. Data…… [Read More]
Apart from the Firewall and IDS for the network security, the company will also integrate encryption system to protect the company network devices.
Encryption is very effective for enhancing security devices of our information systems. The encryption system will assist in enhancing confidentiality and integrity of our information systems. More importantly, encryption will be effective in enhancing our network security because it will protect our system from network-based attacks such as eavesdropping and replaying messages. Typically, the encryption solutions will be integrated at application layer because encryption will assist the integrity of data transmitted across our information system. The encryption will change the data transferred across the information system into unreadable texts so that an unauthorized individual will not have access to our data. With the public key system, we will be able to decrypt the text to have access to the data. (Data Center Fabric, 2013).

Network Security for Vonnie's Distribution Services
Objective of this project is to design network solution and security system for the Vonnie's Distribution Services. The company is considering expanding from the first floor to the third floor within the next few years and the management asks the company Chief Information Officer (CIO) to design a stable, scalable and reliable network security and infrastructure. However, justification of the relationships between security and infrastructure is very critical for the design of the network system.
Justification and Support of the elationship between Security and Infrastructure
In the network environment, organizations are faced two security problems concerning network infrastructure:
Noisy threats and Quiet threats.
Noisy threats are the network threats that interfere with a company network infrastructure, which could disrupt organizational business operations. On the other hand, quiet threats are the threats that cause real damage to the network infrastructure. The noisy threats include network…… [Read More]
Network Security for a Medium Sized Company:
Network security is an important component for all companies including small and medium sized firms because very few businesses can operate without a network of computers. The network of computers facilitates improved communication in order for the company to improve its profitability or productivity. However, the improved communication between computers is also associated with some inherent risks such as malware and unauthorized access. The risk and impact of these threats can be lessened through a good network security policy that is properly implemented and well managed. A good network security policy is essential for a medium sized company since the size of the firm does not prevent it from being targeted by cyber-criminals. The development of a good security policy is the first step towards establishing and managing network security. Some of the important considerations to make for the security policy include network…… [Read More]
History and Evolution of Network Security:
The term 'Network Security' refers to the concept of the creation of a 'secure platform' based upon which the user of the computer or of a program within the computer are allowed to perform only those specific tasks that are allowed within the parameters dictated by the security network of the computer, and banned from performing those that are not allowed. The tasks include the various operations of the access to a program, the deletion of any particular program and the modification to any program. (Network Security: The Concise Tech encyclopedia)
It was during the 1960's that the vacuum-based computers that were being manufactured in the U.S.A. began to become popular, and it was in the year 1967 that the idea of developing 'encrypted passwords' in order to maintain security for the user of the computer was mooted, and, accordingly, the first…… [Read More]

indows Comparison: indows 2000 Pro and XP Desktop Comparison
According to Douglas Ludens of About.com, with the release of indows XP Professional and its home-based XP Desktop Comparison, Microsoft finally delivered on its long-given promise of creating a functional system for both home and professional use. However, there still are substantial differences between the two systems that home and professional users must keep in mind. indows 2000 Professional is still more suitable than the XP Desktop Comparison for professional use, because of the Pro's use of a Remote Installation Service what "automatically" installs "OS, applications across the network." (Ludens, 2004)

Security Issue at the Medical Center
The main security issue at the Medical Center is the protection of patient's identity and keeping patient's data anonymous as much as possible. In the contemporary IT environment, protection of the emerging technologies has become a challenge for many organizations since sophisticated hackers could used different strategies to steal patient's information from the central database, which include Social Security Number (SSN),…… [Read More]
Security is of utmost importance in this digital world where technology has not only expedited our information processing speed but also made information more transparent, with the consequent security implications. The rapid growth of Internet technology and the phenomenal pace at which ecommerce is growing have created new security concerns to be dealt with. We are at a greater risk now from potential hackers and other nosey netizens who use the same technology to gain access to, impersonate, damage and wreak havoc using the anonymous web medium. Firewalls, antiviral programs, authentication systems and secure protocols are different ways of ensuring the safety of the system.
Firewalls constitute the first line defense of our network as they are strategically positioned at the entry point of the network to monitor all input and output data. Firewalls perform the function of filtering data to and from the network and allow only authorized traffic…… [Read More]

Pfleeger, a hash function is used for the provision of message integrity checks and digital signatures. It is a transformation that takes an input and returns a fixed-size string. The basic requirements for a cryptographic hash function are that its input can be of any length but its output has a fixed length. It is said to be a one-way function if it is simply hard to invert. If, given a message, it is computationally infeasible to find a message then it is said to be a weakly collision-free hash function. A strongly collision-free hash function is one for which it is computationally infeasible to find any two messages.
2.The use of SSL ensures that SSL servers and clients can be configured to use only specific cryptographic algorithms.

Project Purpose and Description
The purpose of this project is as follows:
The complex interplay of collaborative effort which every major information technology (IT) project requires a precise system of measurement through which to quantify and qualify the occurrence of success or failure, and this process is best performed with a practical system of project metrics. Traditional project metrics such as customer satisfaction rating and return on investment have been supplemented with the powerful analytics of modern software applications, allowing today's project managers to evaluate every conceivable aspect of an IT project through the objective lens of calculation and computation. It has been consistently observed that enterprises which excel at adhering to predetermined project delivery schedules typically employ a well-defined set of performance metrics to regularly measure ongoing progress (Schwalbe, 2011), because project managers armed with this targeted knowledge are far better equipped to deploy their resources…… [Read More]

Next, firewalls capable of blocking IP addresses need to be installed and used (Becker, Clement, 2006). The focus on these efforts is just the first phase; there needs to be a monthly audit of IP addresses in the departments where P2P file sharing has occurred to make sure it isn't happening again. This an be accomplished using a series of constraint-based configuration tools that will trap on P2P known client footprints or digital signatures and immediately block them (Hosein, Tsiavos, Whitley, 2003). This technology will also work to isolate any inside IP addresses which attempt to reach P2P client-based download sites and immediately log and block all IP activity for the address. This will make a given IP address inoperable and immediately delete it, which will make any subsequent hacking attempts of the system useless. This is precisely the strategy the U.S. Government is using today to ensure a very…… [Read More]

isk analysis projects are relatively expensive, and were so even in the mainframe computing era, because they involved the collection and evaluation of a significant volume of data. Earlier risk studies were conducted by in house staff or consultants and the in house people did not have much experience regarding the matter and the consultants did not know much about the requirements of the organization.
Presently, the familiarization task has become more complicated with the complex, multi-site networked and client server-based technology used now. A new system has developed now and here the first description is of the security entry classification and this classification involves object identifiers which will help the security officer to work. For developing this system, the risk assessors have significant knowledge of operating systems, the documentation procedures are versatile and comprehensive enough to makes the data collection task achievable and since the basic system is ready,…… [Read More]
EP and Information Security
Introduction to EP
Even though the plans of information security include the prevention of outsiders to gain access of internal network still the risk from the outsiders still exists. The outsiders can also represent themselves as authorized users in order to cause damage to the transactions of the business systems. Therefore, strict prevention measures should be taken to avoid such situations.
The threats of both the hackers have been increased with the software of the enterprise resource planning (EP) (Holsbeck and Johnson, 2004). By performing acts of deception, the system privileges are neglected by them and take old of the assets which are mainly the cash. Its continuous integration has not succeeded in eliminating the threat of hackers who are either the insiders or enter through the perimeter security.

If not, what other recommendations would you make to Harold? Explain your reasons for each of recommendations.
No, the actions that were taken by Harold are not adequate. The reason why, is because he has created an initial foundation for protecting sensitive information. However, over the course of time the nature of the threat will change. This could have an impact on his business, as these procedures will become ineffective. Once this occurs, it means that it is only a matter of time until Harold will see an increase in the number of cyber attacks. At first, these procedures will help to prevent hackers from accessing the company's files. Then, as time goes by they will be able to overcome his defenses. This increases the chances that he will see some kind of major disruptions because of these issues. ("Security Policies," n.d, pp. 281 -- 302) ("Computer-ased Espionage," n.d, pp.…… [Read More]

As such, people that use high amounts of bandwidth should be on the up and need to be paying for any extra bandwidth they use. Indeed, many ISP's put hard data caps on data usage and punish (if not throttle) people that are abusive. In the age of Netflix, figuring out what is what can be hard but drilling down to the network traffic in question can clarify that.
However, this even pertains to network managers/engineers at businesses. Whether it be for the data management/hassle avoidance items mentioned above and/or because employees are engaging in unethical (if not illegal) things at work, all of the above needs to be done. General training on virus/malware avoidance has to be engaged in but users should not be expected to get it all right themselves as they will often make very poor choices.

Essentially, the most successful it security systems will rely on a fragmented structure; they may look to third-party or other external local hosting service providers for data that is not as crucial to keep secret. Thus, enterprises must plan for space for "machine rooms that afford high availability and reliability to departmental server resources as well as appropriate network security for these resources" (Clotfelter, 2013, p 7).Then, for more restricted data, in-house servers can provide an extra layer of security to help ensure that such sensitive data remains in proper hands. To protect such restricted data, proper identity management strategies should include "a cross functional client and technical team abstracted requirements for updates" (Clotfelter, 2013, p 5). Thus, enterprise organizations must rely on a tiered network infrastructure that provides a number of different levels of security for various elements of the enterprise organization.

In essence, some hackers use malicious software with an intention to gain access to corporate computer systems…… [Read More]
networking and TCP/IP and internetworking. Also discussed are risk management, network threats, firewalls, and also more special purpose network devices. 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. (Conceptual Overview of Network Security) Though network security in Information Technology is an issue that has been discussed endlessly, implementation has definitely…… [Read More]
In this manner, it makes network management and filtering a lot easier. Even though SPF can protect the network infrastructure against certain attacks that are known to exploit the weaknesses that are inherent in the various network level protocols, it can never provide protection at application level. The application defense needs more awareness of the content of the payload.
Circuit Proxy Firewall (CPF)
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
The payload is then encapsulated in…… [Read More]
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'…… [Read More]
" (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…… [Read More]
Auditing, Monitoring, Intrusion Prevention, Detection, and Penetration Testing
The network vulnerability is a major security weakness that allows an attacker reducing computer information assurance. Vulnerability intersects three elements: a system flaw, the attacker is having access to the flaw, and ability to exploit the flaw. Thus, a security risk is classified as a vulnerability that is tied to a great significant loss. The vulnerability can erode data confidential, system integrity and availability of data.
The objective of this study is to carry out analysis of two research articles that discusses the network vulnerabilities in the IT environment. (Jackson, et al.2008, Sommer, et al. 2003). Both articles believe that attackers exploit the network vulnerabilities to inflict damages in the information systems. Moreover, the two articles agree that the traditional securities such as network IDS (intrusion detection system) (Sommer, et al. 2003) and DNS pinning (Jackson, et al.2008) are no more effective…… [Read More]
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…… [Read More]
Secured real time protocol (STP) is also being identified to enhance the security parameter of WAN and LAN network elements. "STP provides protection with encryption keys for wired and wireless networks including bandwidth limited channels." (Guillen and Chacon 2009 P. 690). There is also a growing use of IP secure to protect organization from the interception of data over the LAN and WAN environment.
To enhance network security, Chen, Horng, & Yang (2008) postulate the use of public key cryptography. While there is a growing use of public key cryptography, there is still a shortcoming identified with the use of public key cryptography in the LAN and WAN environment. Since the public key is being kept in a public file, it is possible for an active intruder to forge the contents of the public key and use it to get access onto the data kept within the network system. To…… [Read More]

Dynamic and Fixed Patch Compliance Level
The goal to achieve competitive market advantages in a business environment has made increased number of business organizations to indulge in online businesses to enhance time-to-market, increase profitability and deliver innovative products. To achieve these objectives, organizations are increasingly investing in the IT (information technology) to enhance effective communication, and transfer data across businesses through LAN (Local Area Network) and WAN (Wide Area Network). Moreover, large number of businesses are switching from wired to wireless network systems to reduce operational costs, capital costs and management costs. (Nicastro, 2005). Despite the benefits that businesses enjoy from IT investments, nevertheless, organizations face inherent risks of IT vulnerabilities, and vulnerabilities can originate from network access points, poorly configured firewalls, wireless access points, and unsecured SQL databases. Vulnerabilities can also arise from weaknesses in the configuration, technology, or security policy. (Nicastro, 2005).
Objective of this paper is to…… [Read More]
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 organizations are usually run by a core group, which divides the different responsibilities of an operation (e.g. spamming, web design, data collection) among the members. The members run their own outer networks to fulfill those responsibilities -- rarely even having contact with each other online. The decentralized structure of the internet, as well as the high levels of anonymity it provides makes it difficult for law enforcement agencies to locate cybercriminal groups. A group could have networks in a myriad of different countries, whilst using servers based in numerous different countries and jurisdictions. Furthermore, many national jurisdictions lack the legislative framework required to properly prosecute online crime." (Collins, 2012)
These insights are illustrating how the lack of self-control is creating a situation where more criminals or organizations are turning to cyber crime. What makes the situation worse; is they can work anonymously and be able to conduct these activities…… [Read More]

It therefore assists in identifying network vulnerability and corrects them immediately.
Ferland (2009) noted that Secure Socket Layer (SSL) is a network protocol used in encrypting data so that the information send remains secure until it reaches its destination. It also used in the validation of the identity of the website which is using certificate. It informs the user the authentication of the website and that such a web site as been validated by the third party certificate authority. Both the source and destination of any send data has their own unique keys for encryption. However, the organization would install SSL certificate so that the customers has trust in our website

It has also opened up a new way for criminals to steal secret data of businesses and information regarding clients' banks details and contacts. This has made customers to becoming rapidly more aware of the websites they visit and where they input their personal information to avoid fraud cases (Corr S. Pondent, 2009).
However, e-commerce security measures deal with issues such as protecting the integrity of the business network and its internal systems. Besides, it ensures that the customer's information is shielded from everybody else, and must not be open to alteration or tampering, whilst going through the process of authentication and receipt. This ensures that there are secure business transaction between the customer and the business (andy C. Marchany, 2002).
E-commerce business has put in place several different security measures to protect customers…… [Read More]
