Computer Security Systems


Computer security systems deal with all computer-related hazards and involve a number of methods, techniques and technologies to prevent unauthorised individuals from accessing to sensitive and confidential information as well as prevent information loss. Computers are, unfortunately, an easy target and computer security systems are therefore essential for both home users and commercial establishments. But besides protecting confidential information from physical and cyber threats, the security systems must allow an easy access to vital information to one or a group of authorised personnel such as employees and customers.

Since an effective computer security must address the entire collection of potential hazards on various levels level, multiple security systems which are focused on specific threats are typically used. They can be generally divided into two categories:

Information protection. Since both home users and businesses have very personal and confidential information stored in their operating systems, information protection is the very most important aspect of computer security. Multiple systems are used to prevent important information from ending in wrong hands including access authorisation, anti-virus programmes, encryption, firewalls, intrusion detection systems and increasing the awareness about the common computer threats and how to avoid them. Examples include choosing passwords that are not easily deciphered by unauthorised personnel, abstain from reading suspicious and unknown emails, put downloads through a virus check before opening them, avoid opening websites which may harm the computer, etc. Ensure you choose a recommended company such as Reboot SEO who are experts in this field.


Data backup. Technically, data backup belongs to information protection, however, it deals with prevention of loss of information rather than theft or unauthorised access. Information loss is a very serious threat which can be just as damaging as an unauthorised access to confidential information. It can occur either due to a system crash or physical hazards such as floods, fires, etc. Various methods can be used to make a copy of important information and protect oneself from information loss. The most common methods involve the use of data storage devices such as USB flash drives and optical storage (CDs, DVDs and Blu-ray discs). But in order to prevent the backup information from falling into wrong hands, they must be kept at a safe location. Another method is the so-called remote backup service in which the copies of files are stored on a remote backup servers via the Internet.

Most of the available computer security systems are focused on prevention. Persecution of an attempted or carried out breach is very difficult because the attackers are almost impossible to identify and persecute, especially the cyber criminals. They are using procedures that are either extremely difficult to track or are located in a different jurisdiction. At the same time, the number of attempted breaches is so large that they are physically impossible to pursue individually, while the law enforcement officers often lack the skills of cyber criminals.
