...Maintaining internet security is of the utmost importance to higher education systems. The majority of universities’ administrative, financial, and clinical systems are available through a campus-wide network (Rasmussen, 2011). This means that highly confidential documents, such as student’s personal information, medical records, and much more are housed on campus servers. This information is vulnerable to security threats and puts the university at risk for lawsuits if the information is exposed. Student’s internet use on campus daily comes in contact with social network targeting, malicious software, infrastructure attacks, phishing, and peer-to-peer file transfers (Rasmussen, 2011). These dangers put not only the students’ computers at risk for security breaches, but the universities’ network as well. The damages resulting from data breaches in college networks are numerous. Not only is having a student’s private information exposed, such as their Social Security number stolen, a nightmare for the individual, but it also causes much additional stress for the university. The higher education system then has to deal with legal issues, public relations fiascos, and various financial losses. In order to avoid any unnecessary headaches, universities go to great lengths to protect their networks from security threats. Organizations storing sensitive data are required by law to have a technology-based deterrent, a monitoring and reviewing method, and a process to lessen the breach...

...American Military University All about Network Security: Network Security Means Never Giving an Adversary a Chance. Anthony Portz 4199864 ISSC340 I001 SPR 14 Professor Alidad Jalinous June 16th, 2014 11:55 PM Introduction In this paper I will discuss network security and I will give a detailed description of the area while discussing different technologies that are involved. There are many ways to provide network security and a lot of different aspects to keep in mind. There are a multitude of people who want to attack the internet and everything that it loves. Well luckily there are big security companies like Cisco and Symantec who are there for the user like Tron, and will constantly defend newly discovered loopholes and vulnerabilities. See what global implications network security has and what the future may hold as I discuss the cutting edge technology and applications that new companies are coming out with. What is Network Security? Network security is a terminology that is used to describe any and all actions that are taken to protect and defend a network. Any action that is driven towards network security should be taken to protect the safety, reliability, usability, and the integrity of the network and all of its data. In order to explain network security a little better, I want to define what a network is. A network is defined as a system or grouping of interconnected items or individuals, and as an arrangement of vertical or horizontal lines that...

...The Tools of Network Security Name Date Class Professor School Introduction Network security can be hard in the environment of constantly changing technology. Strong protection does not have one simple solution. Anyone who is concerned with the protection of their computer, data, or network needs to be ready to spend time researching their specific needs to protect all the different layers and domains that can be attacked. The areas that need the most attention are port scanning, protocol analysis, vulnerability tests, intrusion prevention, firewall use, VPN security, internet filtering, and password recovery. Users need to become proactive when it comes to their network’s security by knowing what tools are the best for the job and being able to implement these tools quickly and correctly. Port Scanning Port scanning and IP scanning is an important step towards network security. A port scanner checks for available virtual ports on your network and can identify if they are open or closed. Finding out which ports are open allows network administrators to take appropriate protective actions by closing or blocking traffic to and from those open (Network Security Tools, 2013). Nmap is the major tool of choice for most network administrators. It is an affordable choice because it is a free open source tool. Nmap supports most operating systems and comes in wither a traditional command line interface or GUI version (Nmap, 2013). Nmap works by using raw IP packets...

...Modern Day Attacks Against Firewalls and Virtual Private Networks Electronic technology is growing at a rapid rate; more devices are made mobile and wireless, but with those improvement and developments come flaws and malicious opportunities. Cyber attacks are on the rise and no system or device is immune. Many organizations employ multiple layers of firewalls but that doesn’t completely eliminate the threat. Attacks against firewalls and virtual private networks or VPNs are constantly being exploited with new methods everyday, but they are yet another obstacle that a cyber criminal must overcome. First let’s discuss what a firewall is and what a firewall is capable of doing. Firewall applications are normally used to protect and secure private networks. A network can have a software, hardware or both firewalls installed and they provide the “ability to control in-bound and outbound traffic”, according to Pirc of Sans Technology Institute (para 2, nd). Most Microsoft operating systems today come with a firewall installed and Microsoft suggests that you should have a firewall set up on each system in your home, even if you have a hardware firewall such as a router that has security policies adjusted, this can help prevent any malicious activity from spreading across your home network. Most firewalls contain a variety of policies but they all at the very least have the same basic policies that can be set up. There are 3 common policies that you...

...IPad’s Security Breach Hacking is one of the things that most people worry about. There is sometimes a need to share personal information to different companies and people for different reasons. Hacking is a way for others to steal, share and use personal information that does not belong to them. It is defined as the use of computer and network resources as a means of obtaining information illegally. Hacking is considered as a felony in the United States (Sabadash, V. 2004). In recent years, people have become more conscious of whom, where and when they provide personal information because they know there is a chance that their information may be taken and used without their permission. When using the internet and other sources, many choose to use secured sites or sites that they trust will protect and keep their personal information private. Although companies usually take all necessary precautions in order to keep their clients information private, there are sometimes flaws in their systems and things may be overlooked. There are many examples of weaknesses with the prevention efforts and some of them are as follows: old software or software that has not been patched, default passwords that are poorly chosen, disabled security controls and web servers with poor configuration, just to name a few (Sabadash, V. 2004). With this assignment, I have reviewed some information regarding the security breach of Apple/AT & T’s IPad. The information has influenced my...

...of service (DDoS) attacks. Typically DDoS attacks occur at the network layer by SYN flooding, ICMP flooding, and UDP flooding. Some times DDoS attacks fail at the network layer when this happens cybercriminals shift to application layer attacks. Application attacks occur by sending an overwhelming number of HTTP GET requests (HTTP flooding) or running a massive number of queries through the victim’s database query or search engine. This guide will address the information technology (IT) industry’s best practices to counter denial of service (DoS) and DDoS attacks. These countermeasures are patch management program, antivirus software, and host-based intrusion prevention systems. Patch Management Program One important aspect of security is patch management. Patching is software code that a vendor distributes to fix functionality problems or vulnerabilities for applications and network devices. Without a patch management program hackers could exploit vulnerabilities to gain access into the university’s information system, elevate privileges, and steal data. The amount of patches released can be overwhelming to the university’s network technicians. The patch management program will ensure that security risks are reduced to an acceptable level and reduce manpower requirements. The university will use an automated patch management system which will include the installation of a client agent. Each host on the network will be required to run the agent. According to Souppaya and Scarfone...

...hard to protect its customer information and the related data that is provided to the bank in order to business with them. In collaboration with Perimeter E-Security Company, West Suburban bank has excellent network security system that recognizes the threats within seconds and figures out a solution to fix the problem. Perimeter E-Security offers excellent information security and messaging services helping many businesses to secure their data from unauthorized users. West Suburban bank took advantage of the services provided by Perimeter E-Security as well in order to protect the assets of their clients. There are hundreds of defense methods however for this paper our major focus will be on the six defenses used by West Suburban bank in order to provide best security services to its clients and protect its information. We will be looking at firewalls, data security, Internet security, application security, access control and anti spyware defenses. Firewalls defense Firewalls implement security at every layer. Firewalls are barriers between a trusted network or PC and the untrustworthy Internet, it is a network node consisting of both hardware and software that isolates a private network from a public network. On the Internet, the data and requests sent from one computer to another are broken into segments called packets. Each packet contains the Internet address of the computer sending the data, as well as the Internet address of the computer receiving the data. (Turban,...

...with the credit card data theft at TJX companies which occurred in July of 2005. According to the book Essentials of MIS, the thieves used a vulnerable wireless network from one of the department stores on the TJX network to gain access. (Laudon & Laudon, 2011, p. 243) After the thieves had access to the network the installed a sniffer program on one of the main computers of the network. They then were able to download any information that they needed to. The TJX Company was still using outdated weak wireless security encryption called WEP, (Wired Equivalent Privacy), instead of upgrading to a more secure version of wireless security, WPA, (Wi-Fi Protected Access). They also did not have any firewalls or data encryption in place. (Laudon & Laudon, 2011, p. 243). The tools that was needed to be in place to help stop this from happening was, the stronger wireless security of Wi-Fi Protected Access (WPA) standard with more complex encryption, they also needed to install strong firewalls, data encryption on computers, and to transmit credit card data to banks with encryption. This breach had some lasting effects on the TJX Company. One of the first effects was that the company had to strengthen the company’s information system security. They also had to agree to have a third-party auditor review their security measures every two years for the next twenty years. (Laudon & Laudon, 2011) According to Essentials of MIS, “TJX has already spent over $202 million to deal...

...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. The primary goals of information security are confidentiality...

...enterprise network. Describe separate conditions for both ingress and egress traffic as they transit the network. Discuss: What roles do ingress and egress filtering play in protecting a network? How do protective isolations help to protect a network? Why do we need to separate and isolate the types of traffic? Ingress filtering is the filtering of any IP packets with untrusted source addresses before they have a chance to enter and affect your system or network. It can protect users from malicious attacks based on spoofing, where a hacker attempts to make a packet look like it originated from somewhere else. Internet service providers (ISPs) typically use ingress filtering to defend their customers and an individual home or office network can have additional safety measures in place. One major use for ingress filtering is to combat denial of service (DOS) attacks. These attacks rely on flooding networks with packets, many of which are spoofed to conceal their origins. The network can catch packets an ISP may not have identified as a problem, depending on the type of filtering used. This adds an extra layer of security for individual users, along with other safety measures like scanning incoming information for viruses and other malicious software that may pose a risk to the safety of computer systems or data on the network. It is also possible to compare the spoofing information against known databases to connect hacking attacks for the purpose of tracking infected computers and...
