Worms

Definition: Worms are a form of malicious software that intrude upon the information assets of individuals, companies and other organizations and then replicate. Part of the mission for this type of malware is to “move on” and infect other computers and information systems. The program can execute independently of the system and do its damage. One of the more nefarious acts it can perform is to leave a “back door” open so that future intrusions can occur.

Its Relevance: All malicious software must be defended against. This particular threat can carry a payload that can cause a full range of damages to the infrastructure and then move on to multiple destinations. The information security infrastructure must have policies against malware and users should be made aware.
