Intrusion Detection and Prevention Systems
IDPS and Components
Intrusion from the outside world, for good or bad, is serious concern in the networked global arena (Ierace et al., 2005). The loss of data and important and confidential business information can be utterly disastrous. Network systems that will detect and prevent such intrusions, therefore, are a necessity of the first order among enterprises. Intrusion attacks can come from hackers, malware or other old or new malicious creations from other sources. Intrusion detection is performed by monitoring computer systems and networks to sense indications of potential threats or violations on an organization's security policies. Another added feature is thwarting these threats before they can occur. Together, these are the components of an intrusion detection and prevention system or IDPS (Ierace et al.).
There are four classes of IDPS according to their functions and the methods they use (Ierace et…… [Read More]
Accounting and Intrusion Detection
In a report issued by Paladin Technologies, Inc., entitled: "Security Metrics: Providing Cost Justification for Security Projects," 273 organizations were surveyed on the topic of security. The report illustrates in quantifiable terms the depth and reach of intrusion detection on the financial viability of the organization. The combined reported losses from the firms surveyed totaled $265.6 million in 1999. The highest loss categories were reported as follows:
Type of Loss
Estimated Dollar Value
Number of espondents
Theft of intellectual capital
The average annual financial loss of firms surveyed was estimated at $40 million. Forty three percent of respondents were able to quantify financial losses, and seventy four percent were able to acknowledge financial loss. Ninety percent detected cyber attacks within the most recent twelve-month period and seventy percent reported serious breaches other than viruses, laptop theft, and employee abuse of…… [Read More]
Attacks on the system security include password theft, back doors and bugs, social engineering, protocol failures, authentication failures, Denial of Service attacks, active attacks, botnets, exponential attacks including worms and viruses, and information leakage. (Fortify Software Inc., 2008); (Fortify Software, n. d.)
Servers are targets of security attacks due to the fact that servers contain valuable data and services. For instance, if a server contains personal information about employees, it can become a target for stealing identities. All types of servers, which include file, database, web, email and infrastructure management servers are vulnerable to security attacks with the threat coming from both external as well as internal sources.
Some of the server problems that can jeopardize its security include: (i) Weakly encrypted or unencrypted information, especially of a sensitive nature, can be intercepted for malicious use while being transmitted from server to client. (ii) Software bugs present in the server…… [Read More]
The subject matter of systems administration includes computer systems and the ways people use them in an organization. This entails knowledge of operating systems and applications, as well as hardware and software troubleshooting, but also knowledge of the purposes for which people in the organization use the computers.
The most important skill for a system administrator is problem solving. The systems administrator is on call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it. In some organizations, computer security administration is a separate role responsible for overall security and the upkeep of firewalls and intrusion detection systems, but all systems administrators are generally responsible for the security of the systems in their keep. (Encyclopedia.com, 2011)
What is a computer network? According to McGraw Hill Online Learning Center, "a network is two…… [Read More]
"As a manager, how would you plan on securing organizational data? How does security effectiveness and relative cost figure into those plans?"
The more critical aspect of any enterprise-wide security management strategy is to align system resources to the strategic initiatives and goals of an organization. Increasingly this is being accomplished through the use of role-based access and authentication privileges and process workflows that audit and evaluate use of sensitive information (Shih, Wen, 2005). The role of enterprise security management drastically changes however when ubiquitous Web Services are used for capturing, aggregating, analyzing and effectively using confidential data to make financial decisions (Phifer, 2011). The intent of this analysis is to evaluate how intrusion and intrusion detection systems can be used in the 21st century, state-of-the-art IT systems that are to a large extent Cloud-based and often have remote access points that make them particularly vulnerable (Phifer, 2011).…… [Read More]
Intrusion Detection Systems: etail-Based Cybercrime and the Importance of Security Point of Sales Endpoints Systems
etail-based cybercrime and the importance of security Point of Sales Endpoints Systems
The recent technological advances have resulted in increased dependability of network-based technology for everyday usage. Points of sales systems have also evolved, and they are now linked to the company's network, which makes them vulnerable to attacks. The number of attacks leveled against POS endpoints has increased steadily in recent times . This is because they are mostly stand-alone and they are used to capture credit card information. The attackers are mostly interested in customer information for fraud or identity theft purposes. In order for POS systems to verify customer information and process credit cards, they need network connection. The network connection provided is dependent on the store. Large stores connect their POS systems to the internal network in order to simplify administration…… [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]

"Unlike IP fragmentation (which can be done by intermediate devices), IP reassembly can be done only at the final destination. What problems do you see if IP reassembly is attempted in intermediate devices like routers?" [ ]
IP fragmentation is defined as the IP (Internet Protocol) that breaks datagrams into smaller fragment to assist packets passing through links and forming a smaller MTU (maximum transmission unit) than its original size. However, the fragments reassemble themselves when reaching the receiving hosts. After the receiving hosts have received the fragmented IP packet, they have to reassemble the datagram before passing it to the higher layer. In practices, the reassembly happens in the receiving hosts, however, a reassembly may be carried out by the intermediate router. For example, the NAT (network address translation) is designed to reassemble the fragments to the translate data streams.…… [Read More]

Hacker Culture and Mitigation in the International Systems
The explosion of the internet technology in the contemporary business and IT environments has assisted more than 300 million computer users to be connected through a maze of internet networks. Moreover, the network connectivity has facilitated the speed of communication among businesses and individuals. (Hampton, 2012). Despite the benefits associated with the internet and network technologies, the new technologies have opened the chance for hackers to attack the information systems of business organizations and collect sensitive information worth millions of dollars. Each year, businesses have been a victim of cyber-attacks in the United States. As an increasing number of people and businesses own internet-enabled devices, more businesses have become a victim of cyber-attacks, which has become a critical concern in the business and governmental environments. (Hacker news, n.d.).
The objective of this paper is to analyze the cyber incidents of the Sony…… [Read More]

In order to maintain information secrecy one would use cryptography. This is intentionally making information unintelligible. This method is mainly employed during the transmission of information. Cryptography ensures that only the intended person would be able to decipher the information (Whitman & Mattord, 2011, p. 339). The process of deciphering encrypted text is referred to as cryptanalysis. Cryptology is the mathematics branch covering cryptography and cryptanalysis. Cryptology has been in use since 1900 B.C. In Egyptian hieroglyphs. A Mesopotamian cryptography was discovered in 1500 B.C. that surpassed that of the Egyptians. The book of Jeremiah was written using alphabet substitution called ATBASH. Cryptography was employed during the First World War to decipher radio communication. Prisoners have also used cryptography to decipher their messages in order to protect their privacy. A key in cryptography is a parameter or piece of information that would determine the functional output for a…… [Read More]
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 all…… [Read More]
Compliance Patch Level
The author of this report has been tasked with discussing the overall subject of patch compliance level. Indeed, the pros and cons of using the patch compliance level framework will be assessed. There will also be an assessment of several critical things such as the patch compliance level of a given patch, what level of patch compliance is safe and what needs to be considered when evaluating the current patch compliance level. Patching is very much a security-related matter and helps both system and network administrators to keep their systems completely up-to-date and as safe as possible from vulnerabilities and hacking attacks. Not applying and installing needed patches to software such as operating systems, firmware, device drivers, databases and so forth can leave an enterprise information technology environment susceptible to attack. While the deployment of patches should be planned and deployed carefully, it is very important to…… [Read More]
If they need to access a site for business purposes, they may not be able to do so, and that can lead to frustration and even lost contracts and opportunities (Miller, 2005). With that being the case, it would seem as though there should be a way to get around these restrictions. If people start avoiding restrictions, though, where does that end? At what point does it become unacceptable and dangerous, and at what point does it jeopardize the privacy, safety, and security of other people who have their information online?
The people who own the information (i.e. The people whose information is being collected) should be the ones to control how secure that information is in the sense of who can see it and access it. Because their names, dates of birth, addresses, phone numbers, and other information belongs only to them, they should be able to determine whether…… [Read More]
detection and intervention in childhood mental health help prevent mental health problems in adult life?
Disregarding the mental well-being requirements of children is an intolerable violation of our basic undertaking to protect their well-being. Unfavorable mental disposition amidst our children is a less acknowledged difficulty that influences their literary, societal, and emotional enhancement. Mental well-being is a wide attribute to be analyzed. The mental well-being requirements of children and youth demand introspection. There is prevalent refuting that mental well-being is comprehensive of the influence on the children -- amidst all age distinct ions, variety of cultural sections, and all income sections. Such miscomprehensions are recurring, and involvement and care are unlikely to be found. Many people have the belief that children having mental well-being difficulties are just under the impact of a particular passing cloud. (Promoting Access for Children to Mental Health Screens and Assessments in Medicaid and the Children's…… [Read More]
Intrusion detection is the method of keeping track of the events taking place inside a computer or perhaps a network and then examining them to get indications of potential situations, that are transgressions or impending dangers of breach of IT security procedures, appropriate usage guidelines, or standardized security strategies. Intrusion prevention is the method of carrying out intrusion detection as well as trying to stop recognized potential situations. Intrusion detection as well as prevention systems (IDPS) happen to be mainly centered on determining potential situations, writing down details about them, trying to end all of them, as well as reporting these to security managers. Additionally, businesses make use of IDPSs for various other objectives, like identifying issues with security guidelines, documenting current risks, as well as stopping people from breaking safety guidelines. IDPSs have grown to be an essential accessory for the security system involving just about any…… [Read More]
Groups -- People sometimes act as a group to steal information for any number of reasons. They may be a company's customer or vendor, or they may be a fierce competitor trying to steal sensitive trade secrets (Elifoglu, 2002).
Some common threat attack groups include the following:
Domestic or Foreign Criminals;
Former Employees (Elifoglu, 2002).
In reality, the concept of intrusion detection systems is a straightforward matter of designing a system that can provide alerts when it is attacked. According to Andress (2003), the process of intrusion detection typically requires the identification of unauthorized access into computer systems. For example, this author notes, "obust intrusion-detection systems are placed at strategic locations on the network to look for suspicious usage patterns so that attacks can be detected before an intruder has gained access to the network, application, or operating system" (Andress, p. 66). This author…… [Read More]

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.
Security plans are a necessary…… [Read More]
However, nothing can be done until the malware actually occurs. With all the different viruses, worms and Trojans, how can security managers possibly predict what malware will occur next? In contrast, a behavioral rule defines legitimate activity in a system. Any activity not matching the profile will cause the security product to be triggered. As rules are not specific to a particular type of attack, they can block malicious behavior without having to recognize the precise attack used. Thus, there is additional protection against new attacks as they emerge. It is to effectively prevent any unauthorized applications, including malicious code and Trojans. or, it could protect a webserver by making it impossible for anyone to access the webserver to change the files and limiting the risk of a hack (Franklin, 2002).
However, the dilemma comes how many rules should the system have? The security manager must decide between an effective…… [Read More]

Warfare: An Overview
In today's age, traditional warfare, though a major player as we see in the Iraq war, has in some arenas taken a back seat to information warfare.
y definition, information warfare is the offensive and even defensive utilization of information and information systems to deny, exploit, corrupt or destroy an adversary's information, information-based processes, information systems and computer-based networks while protecting one's own. Parties use information warfare to gain military, public relations or economic advantage. (www.psycom.net)
Users of information technology are most often nation-states and corporations. For instance, by gaining access to a rival company's databases, a business can get a valuable advantage on price-points and supply chains. Countries can decide how much to spend on military equipment by discovering how much in military stocks adversary nations have.
One major focus recently on information warfare has been hackers. For instance, the most recent generation of mobile phones…… [Read More]

Database Distribution Strategy
Smart Homes, Inc. required a database distribution strategy for its exciting new home thermostat product. As part of initiatives to develop and establish this database, the firm has created its own Web-based system for registering, evaluation, and controlling a user's thermostat through a mobile computing device. The database design must support a smart thermostat registration system that would support some customer service processes. For instance, when a customer installs and powers on the smart thermostat, the device links to his/her home network and sends distinctive device and environment information to the Smart Home, Inc. system. Moreover, the database must support the collection of smart thermostat data like current temperature, energy usage, humidity, thermostat location, and user-programmed temperature schedule.

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]

These can be layered by razor spiral at the top all around the perimeter wall. There could also be a second perimeter wall after the main one as well as security personnel patrolling the perimeter wall to handle any intrusions once detected. This type of perimeter wall works effectively in the layered security model since it gives the detection systems an inhibition backing to prevent intruders from accessing the business.
The intrusion can also come in the form of attempted access through the legitimate means like through the gate where the intruder will come in as any expected traffic. The layered physical security mode will have several choke points at the entry areas. There is the first heavy steel gate where vehicles stop for thorough and systematic checks. Electronic devices are used to check the vehicles and the visitors on foot are expected to go through metal detectors.

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]
Improvements in technology for a public organization: The IS
The IS is a public agency that affects virtually every American's life. Even Americans who do not owe taxes must submit forms to the IS, detailing their economic status. The IS contains a wealth of information that would be of interest to someone attempting to impinge upon the security of the organization, including Social Security and financial data. To ensure people's identities are not compromised and that all financial data is stored in an accurate fashion, the IS's Computer Security Incident esponse Center (CSIC) has the responsibility of "preventing, detecting, reporting, and responding to computer security incidents targeting IS computers and data" (Nevius 2012).
However, there are serious problems with the CSIC. Firstly, a recent audit of the CSIC's found that its "host-based intrusion detection system is not monitoring 34% of IS servers, which puts the IS network…… [Read More]
(%) 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.

The diffused infrared configuration however, uses a transmitter that fills a given office space with signals. The signal receiver can then be located anywhere in the office area in order to successfully receive the I signal.
The Spread spectrum LANs
This form of arrangement utilizes the multiple-cell configuration. Each of the cells are appropriately assigned a unique center frequency that lies within a specific band in order to avoid signal interference. This transmission technique makes use of two methods; frequency hopping as well as direct sequence modulation
The Frequency hopping method uses signals that jumps from a given frequency to the other within a specific bandwidth. The transmission unit then "listens" to a give channel and if successfully detects any idle time (a time when no signal is transmitted),then transmits the packet via the full channel bandwidth .In case a channel is deemed "full," the transmitter then "hops" to the…… [Read More]
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.
Explanation of how hosting servers will affect the above choices
The router needs to link LAN communications on a WAN. However, the leased line is expensive, the paper recommends that the company use…… [Read More]
First, there are some characteristics that differentiate leaders from nonleaders, although experts disagree on whether these traits are inherent or can be learned. However, there is little disagreement that certain types of leadership are better suited to certain working situations. Furthermore, successful organizations are those who manage to find a way to match up leaders to their most appropriate working situation. In addition, different approaches to management need varying levels of leadership. Also, some organizations rely on a group leadership approach, which de-emphasizes the role of any single leader.
One of the most interesting aspects of OB is that a proper understanding of it can help one determine who will make a successful leader. In fact, the five components of EI, self-awareness, self-management, self-motivation, empathy, and social skills, help determine who will become a leader. According to obbins, "the higher the rank of a person considered to be a star…… [Read More]
HIDS are not deployed in the network but rather within the machine or system needed protection. Thus, configuration of HIDS is dependent on the device they are installed on and different devices require different configurations and rulesets. Hybrid IDSes are a combination of two or more IDS components and provides one of the highest levels of protection ion information systems assets and resources. However, this kind of deployment mean more resources need to be allocated to ensure optimum functioning of hybrid IDSes.
From the various IDS components available, IDSes can also be differentiated by their detection types. These detection types can be signature-based, anomaly-based and stateful protocol inspection. The following are the differences in the detection types of IDSes (Scarfone & Mell, 2007):
A signature is a pattern that corresponds to a known threat. Signature-based detection is the process of comparing signatures against observed events to identify possible incidents.
Anomaly-based…… [Read More]

Network security management.
Compliance with the policies and procedures of the company is very vital to the organization, and the policies and procedures should be clearly communicated to the appropriate business teams.
Intruder: The suggested treatment for the attack by the external intruder such as hacker is to ensure that all communication within the organization is encrypted to deter the unauthorized access to the company data. Moreover, the organization should use antivirus to protect the company data from the attack such as Trojan horse, worm, virus etc. Compliance to policies and procedure is so vital to assure an organizational IT security.
Disgruntled Employee: Company needs to evaluate each personnel before being allowed to handle sensitive information. There is a need to conduct background check on each employee. The background check could verify potential employee criminal background, and social background. Employee should be asked to sign…… [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]

The Internet that we know today and use in our everyday lives was founded in the early 1970s. But all through the Cold War, the apprehension of data theft led to the Internet becoming a decentralized system. But it was not until the late 1980s when the Internet, after years and years of research was made available to public. This was a big change because now anyone in the public could gain access of huge amount of data from anywhere in the world. The following list tells us how Internet can be used to spread evil, and assist terrorist organizations to apply more danger and fear to the world. According to Weimann (2004), the Internet has:
- easily approachable
- no single controller or regulator to control or censor information
- the makings for widespread spectators all round the globe
- the power for the user to remain…… [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]
This seems to be a case of some mischievous young men getting in way over their heads and not realizing how serious the consequences of their actions would be. Early on in the investigation, they were apparently laughing about the incident and enjoying their stint in the media spotlight (Poulsen, 2008). Now that they have been sentenced to serious jail time and are forced to pay major restitution, the seriousness of their crime has undoubtedly begun to sink in.
While there was no new legislation specifically attached to the Comcast incident, crimes such as this demonstrate that computer security is an enormously difficult problem for which no simple solution exists. Obviously there are differences between detecting an intrusion attack and preventing one from occurring in the first place. Preventative measures are obviously more helpful and less complicated, however with new intrusion techniques cropping up all the time, it is…… [Read More]
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.

Cyberattacks to Achieve International Threats
Cyberattacks have become a global phenomenon leading to international conflicts among individuals, organizations and in conjunction to military operations. Target of cyberattacks include banking services, critical organizational infrastructures, government networks, and media outlets. Implication of such attacks may be an attempt to achieve both financial and political objectives. Typically, some attackers have defaced websites of different organizations, damage corporate infrastructures, and shut down network systems. Many cyberattacks are political motivated, and sources of these attacks are difficult to trace because most of the attacks are often state sponsored. Cyberspace attackers employ different tactics to achieve their objectives, which include both financial and military gains.
Objective of this paper is to explore the cyber operations and some of the tools that cyber attackers use to achieve their operations.
