Why Are Systems Vulnerable?

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

Since the onset of the first packet switching event that many believe to be beginning of the internet, no other technology besides the printing press has ever transformed the ability to deliver information. Although the internet is used by a large percentage of the civilized world, few Americans realize how vital cyberspace is to our national infrastructure. Today, we are faced with even more threats although it has been a recognized problem since 2009, when President Barrack Obama said “The cyber threat is one of the most serious economic and national security challenges we face as a nation. It’s also clear that we’re not as prepared as we should be, as a government or as a country (Obama, 2009).” Every industry that operates in the United States is dependent on the internet for some aspect of their business. Commerce, transportation, financial institutions, military, as well as industrial control systems are all interconnected. This interconnectedness has created vulnerabilities within their infrastructure that have increasingly become targets of terrorists, script kiddies, foreign governments and hackers of all types.

12.) Know the attacks a hacker might perpetrate and how a hacker might make money from the attacks

Stallings, W., & Brown, L. (2012) Computer security: Principles and practice (2nd ed.). Boston, MA: Pearson.

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

The most common operating system, Microsoft Windows is used to connect the systems to the internet and hence contains various vulnerabilities. Internet Explorer, MS-SQL, file serving and message processing services are the most commonly exploited services of the operating system. There is no operating system that does not contains vulnerabilities and exposures and cannot be targeted by the hackers and viruses. The vulnerabilities in Windows are more popular because of the huge number of machines running it. (Zibstev

The purpose of the report is to explore the current vulnerabilities in the information system network and outline potential

1. What are some of the emerging IT security technologies that should be considered in solving the Problem related to the case?

2. (15 pts) Using general mass-media (such as news sites) identify a recent computer security incident. Discuss the incident in few sentences. Next, find at least three articles on computer security sites that discuss the technology behind the attack / prevention / reaction etc. for the incident. Remember to provide the links also. This part should not be longer than 1-1.5 pages.

I personally believe that one of the greatest challenges facing computing today is security. Nowadays, we have seen a tremendous growth in the usage of computer, whether it is for education, work, communication, science, or for any other reason. However, as our society becomes more computer oriented, the issue of security raises with it. Some people have made their first priority to use the Internet to hurt both individuals and/or organizations. These people have developed techniques to

There are a variety of vulnerability identification factors that are seen as critical. The types of vulnerabilities associated with the Information Technology System depend on the nature of the system itself. Certain rules govern what action should be taken in this step. If the system has not yet been designed, the search for vulnerabilities should concentrate on the security policies of the organization, security procedures, system requirement definitions, vendor and developer’s product analysis. If the system is being implemented the identity of vulnerabilities should to expanded to include more specific information including security features described in the security documentation and results of the security certification test and evaluation. If the system is up and running, then the analysis of the IT system security features and security controls, technical and procedural should be used to protect the system. A table of Security Criteria can be found below:

There are two types of vulnerabilities we face at our company today, technical and administrative vulnerabilities. Technical vulnerabilities consist of improper configuration of software and hardware, a lack of advanced security software and vulnerable

Prevalent to the current trend now is the dependency of the society on Information technology and communication systems. Every aspect of human life is one way or the other linked and controlled by information technology tools. The importance of information technology cannot be over emphasized as its unavailability could lead to a form of disaster or the other. Pivotal infrastructures like finance, healthcare, education and security are driven by information technology. However, information technology and its benefits are accompanied by vulnerabilities and risks that can be exploited by people with the necessary technical skills. Individuals like ‘Hackers’ and ‘Cyber Terrorist’ can cause disruption to information systems, commit financial fraud and also attack computers and networks. These attacks and disruptions could result to violence against people and properties. In some cases, death, serious injuries and severe economic loss could occur as a result of these attacks.
