Security Advisory
IT Security encompasses all that keeps a computer and its data safe, confindential and available.

By 1995 when the use of computers became widespread, network security became a concern.
When the businesses went online in 1998, the internet became an easy platform for hostilities. Then, with the widespread use of e-commerce, the concern for security increased and today, transaction security is an even greater concern as the threats became more destructive.
The graph below shows the evolution of vulnerable targets and the trend which now leans toward transaction security.
Computer security is the process of preventing and detecting the unauthorized access of intruders and viruses. It has become a necessity to implement and maintain up-to-date security utilities and policies in order to prevent the theft or destruction of information and computer systems.
