...Coursework Assignment Title: Perimeter Network Security System Outline Requirements The University is based in Glasgow, and provides higher education services to its students and staff. It is located on a single campus called Campus A. Students and staff use the network services from hosts on various different user networks, as shown in Figure 1 . Due to an increasing number of security violations, a possible redesign of the network infrastructure is to be investigated. You have been hired as a consultant to propose security enhancements, and produce a report. The aim of the exercise is to present a possible solution to the problem at hand by creating a prototype of the new network security infrastructure. This new design should tackle the following components: Provide best practice network egress and ingress filtering at the network perimeter. Create a perimeter firewall, with an appropriate topology to provide the organisations services, including public web, and mail servers. The firewall should have a closed security stance, and provide public services in a secure way. Provide secure access to all devices, from the security management subnet. Additionally, research should be carried out into increasingly common Advanced Persistent Threats (APT), and ways to defend against these using network defenses. This part of the coursework will be research only and be confined to a part of the Research Section. You will be required...

...Deploying Application Firewall in Defense in Depth Principle Abstract Information security should be a priority for businesses, especially when they are increasingly involved in electronic commerce. With the understanding that securing an operating system successfully requires taking a systematic and comprehensive approach, security practitioners have recommended a layered approach called defense-in-depth. The cost and complexity of deploying multiple security technologies has prevented many organizations from achieving their information security goal. In view of these constraints and in compliance with recent with recent corporate and industry regulations like Sarbanes-Oxley Act and Payment Card Industry Data Security Standard, businesses now deploy application firewalls as security measures. Based on the foregoing, the author has recommended the use of application firewalls as a single platform for achieving layered security through network protection, application protection and data protection. This paper commences by examining the defense in depth theory and the types of application firewall and the author concludes by citing the Institute for Computing Applications (IAC) of the Italian National Research Council (CNR) as an example of an organization which engaged application firewalls in resolving its network security problem. Research Analysis/ Body The development of Information security is of paramount importance to organizations that have online presence...

Artificial Intelligence in Cyber Defense Enn Tyugu R&D Branch Cooperative Cyber Defense Center of Excellence (CCD COE) and Estonian Academy of Sciences Tallinn, Estonia tyugu@ieee.org Abstract- The speed of processes and the amount of data to be used in defending the cyber space cannot be handled by humans without considerable automation. However, it is difficult to develop software with conventional fixed algorithms (hard-wired logic on decision making level) for effectively defending against the dynamically evolving attacks in networks. This situation can be handled by applying methods of artificial intelligence that provide flexibility and learning capability to software. This paper presents a brief survey of artificial intelligence applications in cyber defense (CD), and analyzes the prospects of enhancing the cyber defense capabilities by means of increasing the intelligence of the defense systems. After surveying the papers available about artificial intelligence applications in CD, we can conclude that useful applications already exist. They belong, first of all, to applications of artificial neural nets in perimeter defense and some other CD areas. From the other side – it has become obvious that many CD problems can be solved successfully only when methods of artificial intelligence are being used. For example,...

While increasing convenience, connectivity, and productivity, they also pose an unprecedented threat to network security guarding, which has literally taken to the airwaves. This paper will deal with vulnerabilities and risks regarding access points (APs) in a wireless network (WLAN) connecting to a wired local area network (LAN) in enterprises. Data for this paper will come from published academic papers, industry publications including white papers and surveys, and industry specialists. It will also include definitions of terms, policy and procedures that affect access points, and current practices regarding rogue APs. A case study will be presented for a fictional enterprise with multiple locations that has standard procedures, policies, and protocols in place, but recent events have questioned their ability to control access points with the discovery of rogue devices hidden in several office locations. Industry warnings about access points span the past thirteen years, and still new articles appear saying similar warnings, with only the solutions...

...together”. An attack is defined as “an aggressive and violent act against a person or place”. Lastly, security is defined as “the state of being free from danger or threat”. Since the beginning of networking there have been users out there with malicious intent to either gain information or disrupt it. Technicians may not be able to stop the initiation of attack but there are certainly tools and techniques to fight back. This paper will discuss the protocol layers of networking, the associated threats and applicable solutions. This research paper will include an analysis of networking and examples of attacks. While not all solutions will be touched upon, this paper will give you a basic understanding of the way forward.

...Korean War Korean War The Korean War (25 June 1950 - armistice signed 27 July 1953[1] ) was a military conflict between the Republic of Korea, supported by the United Nations, and the Democratic People's Republic of Korea, supported by the People's Republic of China (PRC), with military material aid from the Soviet Union. The war was a result of the physical division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean peninsula was ruled by Japan from 1910 until the end of World War II. Following the surrender of Japan in 1945, American administrators divided the peninsula along the 38th Parallel, with United States troops occupying the southern part and Soviet troops occupying the northern part.[2] The failure to hold free elections throughout the Korean Peninsula in 1948 deepened the division between the two sides, and the North established a Communist government. The 38th Parallel increasingly became a political border between the two Koreas. Although reunification negotiations continued in the months preceding the war, tension intensified. Cross-border skirmishes and raids at the 38th Parallel persisted. The situation escalated into open warfare when North Korean forces invaded South Korea on 25 June 1950.[3] It was the first significant armed conflict of the Cold War.[4] The United Nations, particularly the United States, came to the aid of South Korea in repelling the invasion.

One would be the CISO. The CISO is the executive whose responsibility is to maintain entire security backbone, both physical and digital. In an article written for the Sans Institute by Matthew Cho, “CISO Roles and Responsibilities: According to the latest information, almost sixty percent of the organizations in the United States acknowledge the existence of a CISO dedicated entirely to security (Ware). Responsibilities for these individuals include ensuring proper protection for all physical and technical aspects of the organization. Technical aspects ranging from securing communications, applications, and business systems to performing risk assessments of IT assets exposed to outsiders on the Internet. Physical aspects including non-electronic factors such as physical site access as well as drafting policies and procedures for secure daily operations. Along with overseeing the organization’s physical and technical security implementation, CISOs are also responsible for security management activities. These activities may include training others for security awareness, purchasing security products, planning for and managing disaster recovery, developing secure business and communication...

...Network Security Clint Tipps September 21, 2014 ISSC340/ APUS Prof. Bryan Jensen Abstract This paper will cover several aspects of network security. Numerous different aspects of wired and wireless network security, including protocols applied to secure a network, penetration testing, digital forensics, and network hardening will be covered. There are numerous methods for providing security to a network, and even more to gain access to one. The challenge is to be one step ahead of anyone who may wish to penetrate the network. For this reason, many owners of large networks perform penetration testing in order to identify potential holes in their network. If malicious activity is detected, using digital forensics can help identify where the attack came from. This would, in turn, lead to a network engineer to harden the network against the identified threat. Network Security Over the last decade, computer systems have increased in speed and capacity while decreasing in price. Computers that where once used in corporate environments are now less powerful than a typical household computer. While this sea change occurred, network communications have grown and improved, to allow computers to communicate easily from remote locations, adding vast opportunities for illegal activities. Data can maliciously be changed or destroyed, systems can be made to malfunction and long distance charges can be avoided. One of the biggest challenges today is to control the security of the...

Executive Summary We are pleased to present the 2012 Cost of Cyber Crime Study: United States, which is the third annual study of US companies. Sponsored by HP Enterprise Security, this year’s study is based on a representative sample of 56 organizations in various industry sectors. While our research focused on organizations located in the United States, many are multinational corporations. For the first time, Ponemon Institute conducted cyber crime cost studies for companies in the United Kingdom, Germany, Australia and Japan. The findings from this research are presented in separate reports. Cyber attacks generally refer to criminal activity conducted via the Internet. These attacks can include stealing an organization’s intellectual property, confiscating online bank accounts, creating and distributing viruses on other computers, posting confidential business information on the Internet and disrupting a country’s critical national infrastructure. Consistent with the previous two studies, the loss or misuse of information is the most significant consequence of a cyber attack. Based on these findings, organizations need to be more vigilant in protecting their most sensitive and confidential information. Key takeaways from this research include: Cyber crimes continue to be...
