Internet security is a branch of computer security specifically related to the Internet, often involving browser security but also network security on a more general level, as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. Computer and network security policies define proper and improper behavior; they spell out what is permitted and what is denied. Procedures detail the methods to support and enforce the policies, and usually describe specific steps to take in regular system administration.
