Computer Security – How Much Danger Is Your Computer Really In?

Computer security is a broad term that comprises the overall security of your computer. Different people define computer security differently; some think of it as securing your actual computer so that it will be protected from theft, corruption, or damage caused by natural disasters. Some, on the other hand, think of it as protecting your system from corruption and unauthorized entry. Computer security is also sometimes taken to mean security against viruses, spyware, malware, and harmful Internet-based activities.

So, in general, to completely secure your computer, you have to look into four major aspects: protection of the computer hardware, protection of the information it contains, protection against viruses and spyware, and protection from Internet dangers.

When it comes to hardware security, a computer must be placed in a secure area where it is well-protected from theft and from natural disasters. Despite the advances in data recovery, it is highly recommended to prepare backups of all computer information, especially off-site backups that remain safe even if the original computer system gets damaged. At the same time, the computer and the information it contains must also be easily accessible to the right users, but well-protected from unauthorized users.

This leads to the second aspect of computer security: protecting the entire computer system from unauthorized entry. This is especially important for companies who wish to keep their system and their company information files hidden from unauthorized users and potential information theft. Operating systems are already designed to provide such security, but there are some information that requires stronger security such as data owned by financial institutions and government agencies. In the government sectors, there are various levels of security applied to computer systems, the highest being called High Assurance, which means a robust security system is applied that even classified information are highly protected. At home, such security is usually not necessary, but you may want to use your operating system’s user account controls and password security to nevertheless protect your information and personal data in case hardware security is somehow compromised.

Next comes protection of your system from viruses and spyware, which can both corrupt your data and hack into protected security systems. Virus and spyware protection is a common need in computer security. Viruses are easily transmitted through the use of portable disks that make its way from one computer to another, through e-mails, and through downloaded files and applications. The best protection against these is installation of anti-virus programs, which should always be updated to maintain its optimum level of protection. You also have to install an anti-spyware program, which can protect you from unauthorized hacking into your system.

Most spyware, however, make its way to your computer through the Internet. And that’s another source of danger to your computer security. Internet activities, such as sending and receiving e-mail, using instant messenger systems, downloading files, software, and applications, and so on, can make your computer system vulnerable to viruses, spyware, and a host of other dangers such as cyber bullying, stolen financial information, and identity theft.

Proper awareness of these dangers can help you protect yourself from these threats to your computer security.
