...Can Norton antivirus detect worm’s virus? Fadi M.S Al-suhimat Recent Internet worm outbreaks have infected hundreds of thousands of Internet servers and user machines within minutes, causing billions of dollars in losses for businesses, governments, and service providers. The high stakes involved have inspired numerous research projects, through which industry and academic institutions are working to strengthen local-area and wide-area networked systems’ abilities to fend off cyber-attacks. To that end, we propose to find new algorithm to detect internet worm viruses deploying fast, scalable security overlay networks to facilitate high-speed intrusion detection and alert-information exchange by depend on failure connection. Fortifying the Internet infrastructure with such a solution could benefit many security-sensitive applications, such as digital government, critical infrastructures, grid computing, e-commerce, and law enforcement. The broader impacts are far reaching in science, education, business, and homeland security. Currently, the internet is getting close to the persons’ life. They login internet to chat with others, download files or browse Web Pages. The internet is also playing an important role in the economy of country. Once the internet breaks down, it will cause an enormous economic loss. Worms is a serious security threat that may cause network congestion and internet break down.

...Antivirus is a computer software that has the capability to prevent and protect your computer from dangerous malicious codes. This software can offer a peace of mind even for experienced computer users, who doesn’t want to mess up with viruses. Antivirus programming works in two different ways. Firstly, it has a huge "lexicon" of virus database and it sweeps the files and documents in a system and tags them if they are known to be viral and also it screens the framework of any suspicious action. Another technique includes -making a bait document in critical file systems and monitor about any changes to the document. It has the ability to identify any user interventions and also the changes from any external sources. For people who have good...

...Project Part 2: Vulnerabilities in Information Technology (IT) Security To begin, what’s security vulnerability? Most people think this would be an easy question to answer, but in fact it turns out not to be. This article discusses the definition used by the Microsoft Security Response Center (MSRC) to categorize the variety of issues we examine every day. An unintended flaw in software code or a system that leaves it open to the potential for exploitation in the form of unauthorized access or malicious behavior such as viruses, worms, Trojan horses and other forms of malware. Also referred to as security exploits, security vulnerabilities can result from software bugs, weak passwords or software that’s already been infected by a computer virus or script code injection, and these security vulnerabilities require patches, or fixes, in order to prevent the potential for compromised integrity by hackers or malware. Vulnerabilities a. re what information security and information assurance professionals seek to reduce. Cutting down vulnerabilities provides fewer options for malicious users to gain access to secure information. Computer users and network personnel can protect computer systems from vulnerabilities by keeping software security patches up to date. These patches can remedy flaws or security holes that were found in the initial release. Computer and network personnel should also stay informed about current vulnerabilities in the software they use and seek out ways...

...Keeping information secure in the workplace Hacking A hacker is a person who breaks codes and passwords to gain unauthorised entry to computer systems. A system hacker knows about designing and maintaining operating systems and a password hacker knows how to find out someone else's password. Computer hacking is most common among teenagers and young adults, although there are many older hackers as well. Many hackers enjoy learning more about how computers work and get excitement out of cracking the security of remote computer systems. They often enjoy programming and have expert-level skills in one particular program. For these individuals, computer hacking is a real life application of their problem-solving skills. The purpose of hacking could be anything like to get money illegally, destroying the network, stealing, for the fun or some other motives as well. There are very small numbers of computer hackers in the world because hacking requires lot of knowledge. To prevent this from happening Network security Your business needs to stay on top of changes that could affect the security of your LAN. Keep your operating system updated with the latest security patches and bug fixes. Assign access to directories and other network resources on a need-to-have basis, and remove a user's account immediately when they leave your company. Use network logging and security tests to check your network for security holes and possible break-ins. Passwords One bad password can...

Protecting personal and corporate computer at home or office is very important. It comes to the IT community that no matter how hard a client tries or do viruses will intrude his or her network one day. The importance of virus prevention is to save data and hardware. The software companies give clients tools and directions on how to prevent virus from attacking computers. Antivirus software can prevent some but not all viruses from attacking. The article states “It is a sort of “sleuth and burglar” game being played by antivirus and virus producers. The most and ever updated antivirus, shields you against all defined threats till that time. You can subscribe to auto update feature which works for you behind the screens giving the best possible protection when you go online” (Secureurpc, 2010). This protection software advises the client about suspicious files. When a client cannot catch or kill a worm know as a virus, this software will allow the client to quarantine and run a full scan of the network. Spyware prevention and pop up blockers helps in preventing viruses on a network. As soon as a client connects to the Internet spyware is the automated software that launches and display a report...

...1. What is the main difference between a virus and a Trojan? A virus is a program that is capable of replicating with little or no user intervention, and the replicated programs also replicate further. There is typically a piece of code that causes an unexpected, usually malicious, event (payload) to occur. Viruses are often disguised as games or images with clever marketing titles. A Trojan horse is a program that either pretends to have, or is described as having, a set of useful or desirable features, but actually contains a damaging payload. True Trojan horses are not technically viruses, since they do not replicate, however many viruses and worms use Trojan horse tactics to infiltrate a system. Although Trojans are not technically viruses, they can be just as destructive. 2. A virus or malware can impact which of the three tenets of information systems security (CIA)? Describe how it impacts it as well. Virus maybe can send files to other people that don’t allow reading these files. It will affect Confidentiality. Some virus will break program. Then these programs cannot run. This wills effect Availability. Some virus will change some file in a program. This wills effect Integrity. 3. Once a malicious file is found on your computer, what are the default settings for USB/removable device scanning? What should an organization do regarding use of USB hard drives and slots on existing computers and devices? Besides Vendor IDs and Product IDs, some devices also have...
