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 use to their advantage because each event record might contain communication ports, protocols, services, trust relationships, usernames, etc. The Lookup Service restricts all access to log files by default, but this configuration must be verified. Satisfies: SRG-APP-000118-WSR-000068, SRG-APP-000119-WSR-000069, SRG-APP-000120-WSR-000070
