Section: INFORMATION SECURITY PROGRAM DEVELOPMENT
Explanation:
The effectiveness of virus detection software depends on virus signatures which are stored in virus definition tables. Software upgrades are related to the periodic updating of the program code, which would not be as critical. Intrusion detection and packet filtering do not focus on virus detection.

Long-term retention of business records may be severely impacted by changes in application systems and media. For example, data stored in nonstandard formats that can only be read and interpreted by previously decommissioned applications may be difficult, if not impossible, to recover. Business strategy and direction do not generally apply, nor do legal and regulatory requirements. Storage capacity and shelf life are important but secondary issues.

The value of the server should be based on its cost of replacement. The original cost may be significantly different from the current cost and, therefore, not as relevant. The value of the software is not at issue because it can be restored from backup media. The ALE for all risks related to the server does not represent the server's value.
