Computer Security Explained

The use of computers and the Internet is growing each day. Companies of every size depend on computers to conduct their daily business. Computers are used to store large amounts of information, much of which is personal and confidential. Individuals count on the companies they deal with to protect any personal or confidential data they provide about themselves. The companies also need to protect their own intellectual property from loss or theft. Add to this the fact that computer crime is growing, and is now moved from the realm of kiddy hackers out to prove their computer prowess to organized criminals out for financial gain. This puts us in an environment where the risk of theft of confidential information from computers is high, and the threat of computer fraud is always present. The sophistication of the attacks is also increasing at an alarming rate, making the need for strong security countermeasures more critical than ever. It is a constant battle between those trying to protect computing infrastructures and those trying to break in.  The job of the computer security professional is to protect his her employer's computers and networks from attack, by:
