Title

McAfee VirusScan On-Access General Policies must be configured to log any failure to scan encrypted files. (Cat II impact)

Discussion

While logging is imperative to forensic analysis, logs could grow to the point of impacting disk space on the system. In order to avoid the risk of logs growing to the size of impacting the operating system, the log size will be restricted. If the data in the log file exceeds the file size set, the oldest 20 percent of the entries are deleted and new data is appended to the file, so although the file size is restricted, it must also be large enough to retain forensic value.
