Definition: - Antivirus software seeks out and recognizes the "signatures" of malicious code that is capable of violating the confidentiality, integrity and availability of information resources. Among the top publishers are Norton(tm), BitDefender(tm), Kaspersky(tm) and Webroot(tm). Licenses can be purchased from these companies for computers or networks for varying time periods.
This protective software is installed on a computer or network and establishes a baseline or "clean slate". The user or network administrator controls how often their computer systems are scanned for viruses. The content of any in-bound messages can be scanned for anomalous code by comparing the content of the message with a database of known virus "signatures" or traits. Periodic updates are produced by the publishers as the need arises and can be downloaded routinely as part of the licensing agreement. Infrastructure owners typically automate updates from the publisher as a matter of routine.
Its Relevance: Viruses, as a group, are a major threat vector to the viability of an organization’s information assets. The intent of this type of malware is to compromise or destroy the integrity of an information processing system. There are thousands of variants. Unless the nefarious software can be detected, removed or prevented from “infecting” a computer or network serious damage can occur.
