...Maintaining Information Security CMGT-400 Assurance and Security 5-25-2013 Maintaining Information Security Maintaining the security of information couldn’t have been said any clearer than by Lindsey Walker of InfoSec Island, when in 2010 she wrote an article about sensitive information becoming breached. She said “Preventing information security breaches needs to become a main priority for any company when handling both customer and company information”. Sharing information has become much easier than in previous years, from the widespread mainstream use of USB thumb drives or the constant urge to share some secret news or research on Twitter and other social media. The need for a company to constantly review and update their information security policy periodically has never been greater than now. Security Policy An Information security policy should be written in a way that defines how digital information should be protected and accessed by all company employees. Most information that is used to define the Information Security Policy can be gathered by first running a risk analysis report. These reports look at your business model and create a data structure that can be used to inform a company about where their greatest risks are within the company and around the entire work place. Certain “must-have” check boxes for items that should be included in an information security policy are Acceptable Use Policy, Wireless Policy, Email Policy, and Encryption Policy. These...

...| Cyber Security | | Patrice Brockington | 4/20/2013 | | Cyber Security The security of online files, applications, documents, consumer information, and organization information are just some of the valued items that need to be secure from cyber threats. Companies and organization that utilize the internet to conduct business know all too well the importance of securing the information and any and all information of those that they do business with. Having some general knowledge of what cyber security is and the importance of it is our purpose in this brief. Cyber security is the “measures taken to protect a computer or computer system (as on the Internet) against unauthorized access or attack”, as defined by Merriam-Webster.com (Online, 2013). In general practice cyber security is simply securing online information and service systems. If you ever entered your name, address or any personal information online or into some database to win a prize this information is online or somehow accessible via the Internet. It is this type of information that so many millions of people are concerned about if it is secure or not, since it is out on the Internet. “The nation’s critical infrastructure relies heavily on the Internet for everything from submitting taxes, to applying for student loans, to following traffic signals, to even powering our homes” (Government, 2013). This is why cyber security is one of this country’s most important national security priorities...

...Bus. 101 1/2/13 Cyber Security Cyber security is defined as actions taken to safeguard information technology or computer systems against unapproved access or attack. Cyber security has become really important for businesses and modern society today. We are living in a world where information technology and other types of communication systems have a great impact on us because they infiltrate every aspect of our lives. This builds a protection of our intangible assets and actions within cyberspace which are of great importance, whether for sustaining a prosperous business, individual life and society. We are becoming more and more dependent upon information technology and the dangers we face are organized and growing. There are numerous threats that involve the cyber world. Among these are the hackers infiltrating into people’s systems and damaging files, viruses that are eliminating the system, individuals using others devices to harm others, someone pocketing your valuable credit card information to make their own purchase. Attacks from hackers and terrorist have prompted the focus on cyber security. Whenever we mention cyber security, we are focused on the prevention, revealing and reaction to attacks and threats having to do with information in your computers. As mentioned by Prof. Moss, IT security threats are more and more focused on the robbery of valuable data. Frequently, there are malicious codes or malware that pass through our security systems when we access...

...The Importance for Cyber Security BCOM/275 Cyber security is an essential element to any business and our Government. Unfortunately many corporations do not realize the importance of computer security until it is too late and have experienced a cyber-attack. The consequences of such an attack can be quite severe, as businesses carry an obligation to everyone involved to protect their identity and personal information. Today we are more reliant on computers and to the networks related to them more than ever, because of this reliance, security has become priority number one. Cyber security is an essential factor to be measured in order to defend ourselves and livelihood from hackers and dangerous software designed by people with ill intent. The majority of these dangers to computer networks come from the internet and these are frequently intended to have terrorist like effect on networks and most importantly, people’s lives. Recent attacks have been very high profile, including the Sony hack which is still being investigated. Cyber security is, therefore, by definition an attempt by an individual or entity to protect their personal information and data from cyber-attack. Cyber security involves multiple steps, the most significant of these being an individual’s understanding of the diversity of these cyber-attacks. Once one has knowledge of this, then it is the individual’s responsibility to make sure they have reliable and up to date software...

... Companies must pay close attention to secure their computer networks from would be intruders. In order to maintain the highest level of security within the os servers you must first have knowledge of the vulnerabilities of the running operating system. It is those vulnerabilities in the system that the intruders will be searching your network for. The known shortcomings and vulnerabilities of Windows and Unix/Linux servers have dysfunctions that can be exploited to gain access to a company’s private information. This information in the wrong hands could cost an organization millions of dollars in security damages. One of the ways to prevent this type security breech is to make sure that your Windows and Unix/Linux servers has the right up dated patches for these operating systems. According to, (Conklin, W. A.2009) “One of the most effective measures security professionals can take to address attacks on their computer systems and networks is to ensure that all software is up-to-date in terms of vendor-released patches. Many of the outbreaks of viruses and worms would have been much less severe if everybody had applied security updates and patches when they were released.” Ignoring the update prompts on your system is not a wise thing to do. New vulnerabilities in operating systems are discovered every day. According to, Goodrich, R. (n.d) “Software patches serve a very important role beyond annoying computer users. Their intended purpose is to quickly push out...

...Importance of Firewall MedIQ is going in the right direction by adding a firewall in their network. The importance of a firewall is that it blocks malware that would be able to scan your computer to find its vulnerable areas and then attempt to break it while it is at its weakest point. First of all there is only one way to make your computer completely safe from attack and that is either when it is off or unconnected from the Internet. Other than that there are always vulnerabilities. However, you can make it as close to hacker proof as possible while it is connected to the Internet. The way to do this is to have a personal firewall installed along with antivirus and anti spyware protection. Plus you have to make sure that all three of these are updated on the regular. Additional protection is available to a network that used a router with a firewall feature. Firewalls protect your computer from outside attacks by guarding it from unnecessary Internet traffic. They can however be configured to block certain data while letting other data in. The importance of a firewall on your computer can not be underestimated especially for those who are always connected to the Internet. Firewalls are positioned between your computer and your network and are great for protecting multiple computers but also offer a great degree of protection for single computer use. It allows individual users decide how much content they want to filter through and what websites are safe to use. In some...

...Hardware and Software: The Means to Security and Communication Hardware and Software: The Means to Security and Communication When people think of military, they often tend to think of superior power and advance technology. Nothing could be farther from the truth. In reality most military computers are generations behind the technology curve. When the military chooses hardware, it typically looks for several unique characteristics. What to Look for According to EHow.com there are three main things to look for when planning on buying a computer. The Random Access Memory (RAM) allows move programs to run at a time. Hard Drive space allows the user to save information to the computer to be accessed later. Finally the other thing EHow.com recommends is to get a reliable brand name so you won't have to troubleshoot in the future ( EHow.com, 2011). When the military prepares to buy computers, it does in bulk. Not only does the military buy many computers, but they search for different characteristics. Out of the three common things that average consumers look for, only one really matters when it comes to military computers. Random Access Memory (RAM) is not as important on most military computers because each computer is not designed to handle that much graphics or to many programs at once. Military Hardware There a many specialized computers designed for weapon systems that are specifically designed to meet the demands of their specific weapon...

...people who have access to technology and those who lack access to technology. Clearly, computer technology has brought about significant ethical and social effects among people from all dimensions. The significance of the digital divide can be witnessed at school and work. The evidence of a digital divide can be seen in terms of the differences in access to computer technology. Different obstacles that limit the access to computer technology for some individuals have caused the divide. Access to computer technology is limited by the differences in geographical areas. From the geographical perspective, statistics indicate that individuals living in suburban areas have a higher access to computer technology both online and computer access as compared to rural and central city residents (Kizza, 2002). Income levels also determine the access to computer technology since computer gadgets or devices are monetized thus individuals have to purchase them and this poses a challenge to people who experience financial constraints. Other -issues include ethnicity where statistics indicate that white non-Hispanic individuals have a higher access to computer technology as compared to other individuals. Age and education also determine the access to computer technology. I agree with Kizza (2002), The digital divide has significantly affected the virtual workplace since only employees with access to computer technology. The disadvantage of the digital divide is that organizations may fail in...

...been major security threat for web based application. It allows attacker to use multiple computers situated far away from each other to attack on single victim computer. It not only affects the services given by the application but makes it hard to stop the DOS attack. Our project concept is to implement a practical IP traceback system that will track the DOS packets to its original source. To achieve this we use Flexible Deterministic Packet Marking (FDPM). FDPM provides a defense system with the ability to find out the real sources of attacking packets that traverse through the network. While a number of other traceback schemes exist, FDPM provides innovative features to trace the source of IP packets and can obtain better tracing capability than others. We are going to simulate FDPM system in NS2 which is network simulation software and study its various advantages and disadvantages as well as its application. 2.)

...A Case Study on How to Manage the Theft of Information Robert M Polstra III Kennesaw State University 2004 Westwood Rd Smyrna, GA 30080 404-641-8937 rpolstra@hotmail.com ABSTRACT 1. INTRODUCTION This paper shows the importance that management plays in the protection of information and in the planning to handle a security breach when a theft of information happens. Recent thefts of information that have hit major companies have caused concern. These thefts were caused by companies’ inability to determine risks associated with the protection of their data and these companies lack of planning to properly manage a security breach when it occurs. It is becoming necessary, if not mandatory, for organizations to perform ongoing risk analysis to protect their systems. Organizations need to realize that the theft of information is a management issue as well as a technology one, and that these recent security breaches were mainly caused by business decisions by management and not a lack of technology. After counter-terrorism and counter-intelligence, cyber crime is the third highest priority for the U.S. Federal Bureau [4]. With the rise of the theft of information and the lure of big profits for this stolen information, it is necessary for information systems to have the ability to protect this valuable asset. It is estimated that a credit card number unsupported by any other documentation is worth $10, and a credit history report retails for $60 [2]...
