Computer security is an essential part of any computer system. It is an aspect of computer science that deals with all the associated risks that come with computer use and involves many techniques. Protection of the system can be enhanced by securing crypto processors. There are list techniques like capability and access control that ensure separation and control over indiscriminate access. Backups are very important in any security system. Antivirus programs and firewalls also work toward ensuring security.

Computers are an easy target, as they contain important personal information that can be easily misused by people who make hacking their main job. Hackers are mainly looking to ride piggyback on someone else’s time and money. So any information regarding your Internet access, your hard disk, your processorthey’re all of immense use to them.

Hackers break into a computer using emails with encrypted virus coding in them. Once these emails are opened the program goes active and the intruder has then gained sufficient access to read all your personal and business related information. Passwords too get decoded by this program, and your system is then vulnerable to any bug attack.

One way of preventing this is to abstain from reading emails that look unfamiliar. Any information that you download should be put thorough a virus check and then opened. Backup of all your sensitive data is very essential. And all this should be kept in external storage devices. Antivirus programs are very smart and most can easily trick a computer system into finding nothing wrong with their system. Ensure that your virus software has facilities like self-updating; updating of new signatures of viruses, etc. Make sure your antivirus program does most of the clean-up work for you.
