Computer crimes are on the rise as more people rely on computers for their every day life and businesses and more criminals are taking to the internet for many different types of cyber crimes.

Computer security forensics is a practice designed to keep up with this evolution of crimes and is a science that has been around for a long time. The industry is changing each day and as new internet crimes are created by skillful hackers, digital forensics experts have to keep up and find new ways to access and analyze data.

Computers and other media devices that store and send data are the key witnesses in many cyber crimes. If someone is doing questionable activity on a computer, even though they delete the materials, it is still recoverable by the computer forensics process. Data can be accessed to determine what it is, where it came from and who sent or received it. Pretty much any relevant information needed can be found when accessing a computer.

Computers are an inseparable part of our lives today, life that has increasingly become technology driven. Besides work, we use computers for communicating, banking, entertainment, research – just to name a few. Besides hardware, security of the new-age machines is threatened by malicious software, viruses, Trojans etc. all designed to cripple a system. Loss of computer security leads to corruption or loss of data, misuse or theft of information, identity theft and unauthorized use of client information, transmission of computer viruses that can affect third parties and can lead to potential liability, services interruptions, security breaches at vital government installations that can threaten national safety. For corporate houses, loss of computer security can make vital difference in acquiring new work and sustaining current projects.

These are strong reasons to computer support the need for installing computer security systems. The first important requirement is licensed Anti-virus software. There are over 50,000 known viruses and 200 new viruses are discovered every month. The easiest method for spreading viruses is by e-mail attachments or instant messaging messages. Viruses can be disguised as greeting cards, funny images, or video and audio file attachments. The computer needs to get updated with latest threats and that is possible only with original computer security software as it gets automatically updated every time the machine goes online.
