======5.2.3 Ensure SSH LogLevel is set to INFO (Scored)====== =====Profile Applicability===== Level 1 - Server Level 1 - Workstation =====Description===== The ''INFO'' parameter specifies that login and logout activity will be logged. =====Rationale===== SSH provides several logging levels with varying amounts of verbosity. ''DEBUG'' is specifically //not// recommended other than strictly for debugging SSH communications since it provides so much data that it is difficult to identify important security information. ''INFO'' level is the basic level that only records login activity of SSH users. In many situations, such as Incident Response, it is important to determine when a particular user was active on a system. The logout record can eliminate those users who disconnected, which helps narrow the field. =====Audit===== Run the following command and verify that output matches: # grep "^LogLevel" /etc/ssh/sshd_config LogLevel INFO =====Remediation===== Edit the ''/etc/ssh/sshd_config'' file to set the parameter as follows: LogLevel INFO
