Computer security is a branch of computer technology which is also known as information security as applied to computers and networks. The objective of computer security is to provide protection of information and property which is from theft, corruption or natural disaster. It also has to allow the information and property to remain accessible and productive to its intended users. .There are a number of strong reasons for computer support and the need for installing computer security systems. The very first important requirement is to obtain licensed anti-virus software. There are over 50,000 unknown viruses and 200 new viruses discovered every month. These can be disguised in many ways such as email attachments, instant messaging messages. They can also be sent as birthday cards online, video or audio attachments to emails or funny images. This means that the computer will need to get updated with the latest threats and that is only possible with original computer securi ty software as it will get automatically updated every time the machine goes online..The technologies of computer security are based on logic. Access authorization restricts access to a computer to group of users through the use of authentication systems. These systems can protect the whole computer through a logon screen or individual services. There are many ways or identifying and authenticating users these are such as passwords, identification cards and now also smart cards and biometric systems. Anti-virus software consists of computer programs that attempt to identify and eliminate computer viruses and other malicious software (malware). Applications with security flaws should not be run. .Backups are a way of securing information and to keep a copy of important computer files kept in another location. These could be kept on hard disks, CD-Rs, tapes or CD-RWs. Some companies keep their back up files in a safe deposit box inside bank vaults.

It is also important when natural disasters happen..Encryption is used to protect the message and keep it private to the intended user. Firewalls are systems which help protect computers and computer networks from attack and intrusion by restricting the network traffic which can pass through them set on a system of system administrator rules. Firewall software also enhances computer security by controlling communications from it; this will also prevent unwanted access and is capable of blocking outgoing and incoming IP addresses..Computer security is often compromised due to spyware that enters the machine by deceiving the user or through some software loopholes. Sometimes the user can be tricked into unknowingly installing it. Hence, spyware removing software is a must in the computer security system. .Lastly a pop-up blocker is ano ther important factor in securing computers. Malicious attackers are likely to use a pop-up window that is concealed as a special offer to set up a malicious code..So many reasons to get yourself licensed computer security software for your computer before you attempt to go online.
