Viruses and Worms This paper is about computer viruses and worms. Maybe the term virus is not the first thing to remember when we talk about computers but viruses play an important role in using them. Lets start from the definitions of what are the viruses and worms are. At first I want to emphasize that both viruses and worms are malicious programs, which can damage a computer. We need to know the difference between the two of them if we want better protection for our computer. Vangie ‘Aurora’ Beal states A computer virus attaches itself to a program or file so it can spread from one computer to another, leaving infections as it travels. Much like human viruses, computer viruses can range in severity; some viruses cause only mildly annoying effects while others can damage your hardware, software, or files (The Difference Between a Virus, Worm and Trojan Horse?) You need to know that almost all viruses are attached to the executable file.
That means that virus can exist on your computer but infects it only when you run or open the malicious program. We must to remember that viruses are spreading because of the human actions. Mostly, people do it unknowingly. Vangie ‘Aurora’ Beal explained, Worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the ability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided.
The Essay on Security Viruses And Worms
Security Security is essential to maintain a functioning network and productive employees. These security recommendations should be implemented to ensure a safe and secure operating network where there are minimal fears from outside influences such as viruses, spam and hacking activities. An electronic workplace policy will be implemented to protect the network from within. All employees are ...
(The Difference Between a Virus, Worm and Trojan Horse?) The main danger of the worm is its ability to replicate itself and send hundreds and thousands of copies of itself. The damage from the worm is much greater than from virus. Vangie Aurora Beal outlined that Due to the copying nature of a worm and its ability to travel across networks the end result in most cases is that the worm consumes too much system memory (or network, bandwidth), causing Web servers, network servers, and individual computers to stop responding. In more recent worm attacks such as the much talked about. Blaster Worm. the worm has been designed to tunnel into your system and allow malicious users to control your computer remotely.
(The Difference Between a Virus, Worm and Trojan Horse?) computer security is very important nowadays and CERT (Computer Emergency Response Team) is the most competent expert in this field. Larry Rogers states Computer security has been, is, and will continue to be a hot topic for discussion (The Goal of Computer Security or What’s Yours is Yours Until You Say Otherwise, 2005) The CERT Web site contains various information about viruses latest attacks and protection methods. The main parts are Vulnerabilities, Incidents and Fixes, Security Practices and Evaluations, Survivability, Research and Analyses, Training and Education. Viruses and worms usually attack computer-based possessions such as disk space, memory, CPU cycles, Internet connectivity and speed, software, files and folders. Having your computer safely protected is very important. Why? Larry Rogers answers on this question Technology changes rapidly, as do the ways intruders take advantage of that technology. If you know the goal of computer security, you can better adapt to these inevitable technological changes.
And you can better safeguard your computer resources against the inevitable intruder attacks, keeping what belongs to you yours until you say otherwise! (The Goal of Computer Security or What’s Yours is Yours Until You Say Otherwise, 2005) So lets observe three computers attack and discuss what each attack did, what types of systems were affected, and what course of action or remedy was proposed. September 19, 2005 security researchers at Panda Software reported about new worm that generated a spoofed version of Google. Virus lures users into launching the P2Load.A on their computers using a faked error message. Matt Hines states, Once the virus has been sprung, it immediately modifies the computer’s start page, launches the adware and spoofs Google. As part of its delivery function, the P2Load.A attack modifies an infected computer’s Hosts file so that when an unsuspecting user attempts to call up the search engine, they are instead diverted to the mocked-up version of the site. However, PandaLabs security system stopped the spreading of this worm.
The Essay on Complete Computer System
The new Power Mac G4 is up to twice as fast as the fastest Pentium III-based PCs. With its Pentium-crushing speed and new design, the Power Mac G4 picks up where the old Macintosh (G3) left off. Its enclosure is now highly polished silver and graphite, yet it still offers easy access to every internal component through its swing-open side door. With PowerPC G4 with Velocity Engine, the computer ...
Luis Corrons, director of PandaLabs advised users to use firewalls and antiviral protection. Reed Stevenson reported about two worms IRCBOT.WORM and RBOT.CBQ . The worms exploit a recently discovered flaw in Microsoft Corp.’s Windows 2000 operating system. They were causing PCs at more than 100 U.S. companies to restart repeatedly and potentially exposed them to attackers who could take control of a system. (Worms target Microsoft’s Windows 2000 operating system. August 17, 2005) In that case, Symantec Corp. and MacAfee, two large computer security companies, limited the damage to computer systems.
At August 15, 2005 Robert McMillan wrote about new virus. Microsoft Corp.’s Windows 2000 Plug and Play was attacked with so called Zotob. According to Johannes Ullrich, chief research officer with the SANS Institute, a Bethesda, Md., security training company, The worms spread using the TCP/IP Port 445, which is associated with Windows file sharing, and take advantage of the Plug and Play system bug to seize control of the operating system. Infected computers are then told to await further instructions on an Internet Relay Chat channel, meaning that they could then be used to attack other systems (Zotob worm exploits Windows 2000 Plug and Play, August 15, 2005) Fortunately, Microsoft correct their program mistake and SANS has published instructions on how to check if they are enabled.
