Abstract

Information security requirements within a society have changed a lot in the last few years. In this era of Face book, What’s App, Twitter and Google maps, where anyone can upload anything in the social media and track anyone’s location using GPS, everything is possible. However, we need to be more conscious in security. The introduction of distributed system and the use of networks and communication facilities for carrying data between the terminal user and computer affected the security of information. Network security measures are needed to protect data during their transmission.
