Description
Log data is essential in the investigation of events. The accuracy of the information is always pertinent. One of the first steps an attacker will undertake is the modification or deletion of log records to cover tracks and prolong discovery. The web server must protect the log data from unauthorized modification. ESX Agent Manager restricts all modification of log files by default but this configuration must be verified. Satisfies: SRG-APP-000119-WSR-000069, SRG-APP-000120-WSR-000070
