Description
Log data is essential in the investigation of events. If log data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be difficult, if not impossible, to achieve. In addition, access to log records provides information an attacker could potentially use to their advantage since each event record might contain communication ports, protocols, services, trust relationships, user names, etc. Satisfies: SRG-APP-000118-WSR-000068, SRG-APP-000119-WSR-000069, SRG-APP-000120-WSR-000070
