Computer Security

A lot of individuals wonder whether or not their computer is safe. They fear that someone might be looking through their files, copying, changing, or erasing them. They are uneasy concerning the thought that someone might be tracking their every move in cyberspace. Fortunately it’s not difficult to prevent these difficulties by following a few simple suggestions.


Probably the most essential measure for computer security would be to be sure it stays updated. This really is made simple by configuring the system if available, to use Automatic Updates. If not, updates may be downloaded right from Microsoft’s download centre. Currently, Service Pack 2 (SP2) is the most current Service Pack for Windows XP.


The simplest way to improve the security degree of a computer is by using a firewall. They act as a “wall” with one or more computers on one side, and one or more computers (usually the Internet) on the other. Information transfer by funny programs are instantly cut off, preventing them from entering the protected side of the firewall. This way refusing access to anything coming from unknown and unauthorized sources prevents possible infection by viruses, worms, and other malicious codes.

Anti-Virus and Anti Spy-ware

A computer is still necessary to use anti-virus and anti spy-ware, even if it is protected by a firewall. This is because a firewall just prevents unauthorized external access, and can’t differentiate between benign and malicious access. It’s still potential to accidentally make a request for information that is not harmless, which the firewall perspectives as an authorized transfer. Antivirus and anti spy-ware supplies another tier of armour for a computer, which makes it harder for hackers’ malicious applications as well as they to penetrate and control a computer. Some well-known antivirus applications contain McAffee, Trend Micro PC-cillin, and Norton. Anti spy-ware applications are also important as hackers reduce the odds of spy ware getting into a computer. Spyware behaves differently than viruses, which makes it necessary to utilize different programs to capture it. Spyware can track any task a computer performs, or act as a gateway to download viruses or additional spyware. Hackers commonly use spy-ware to get significant information that must remain private like police records, and credit card numbers, social security numbers.

Shield Home Networks

It’s not impossible for a computer owner to be unaware they are using a network at home. If more than one computer shares the same Internet connection or if wireless Internet access is being used, a home network is present. Securing one computer is not much use if it is part of a network. The entire network should be shielded also to prevent malicious software from just jumping from computer to computer to avert assault. Different kinds of home networks face different types of hazards. In the case of a wireless connection, anyone within the transmission range of the network may be able to look at any data comprised within the network.

Most networking devices apply their own security mechanisms. Using this in combination with security defenses installed on each computer’s should supply enough protection to thwart attempts from hackers use the computers connected to the network and to hijack it.

While no measure can guarantee total resistance from attack, these steps should increase the security of a computer or network enough to shield against any typical attack.
