Computer SecurityThis is basically a branch of computer technology also referred to as information security as applied to computer systems and network infrastructures. The main objective behind computer security entails protecting information and property from natural disaster, corruption, or theft while at the same time allowing information and property to be accessible and productive to its legitimate users.
Intruders not only target money related information, they are also after computer resources such as fast internet connection, fast processing speed and huge hard disk space. These intruders have devised ways whereby they can use these particular resources to attack other systems on the network. It can be said that the more intruders use computer systems to facilitate their attacks, the more difficult it becomes for law enforcement agencies to figure out where the attack is originating from.
Intruders are very much inclined to attack home and small business computer systems because in most cases these systems are rarely secured and very easy to hack into.
Often an intruder accesses computer systems remotely by sending e-mail messages containing virus attachments that when a user unknowingly reads the email, they automatically activate the virus program hence creating a loophole which can be exploited by intruders to remotely access the computer system. In some other cases, intruders may take advantage of software vulnerabilities in order to gain access. Immediately these intruders gain access to the system and they often install spyware programs that enable them to continue using the computer system even if the original loopholes have been patched.
