SLEM 5 must generate audit records for the "/var/log/btmp" file.


Overview

Finding ID Version Rule ID IA Controls Severity

Description
Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).
