| 2 | # |
| 3 | # Profile Applicability |
| 4 | # --------------------- |
| 5 | # - Level 1 - Server |
| 6 | # - Level 1 - Workstation |
| 7 | # |
| 8 | # Description |
| 9 | # ----------- |
| 10 | # The INFO parameter specifies that login and logout activity will be logged. |
| 11 | # |
| 12 | # Rationale |
| 13 | # --------- |
| 14 | # SSH provides several logging levels with varying amounts of verbosity. DEBUG is specifically |
| 15 | # not recommended other than strictly for debugging SSH communications since it provides |
| 16 | # so much data that it is difficult to identify important security information. INFO level is the |
| 17 | # basic level that only records login activity of SSH users. In many situations, such as Incident |
| 18 | # Response, it is important to determine when a particular user was active on a system. The |
| 19 | # logout record can eliminate those users who disconnected, which helps narrow the field. |
| 20 | # |
| 21 | # Audit |
| 22 | # ----- |
| 23 | # Run the following command and verify that output matches: |
| 24 | # |
| 25 | # # grep "^LogLevel" /etc/ssh/sshd_config |
| 26 | # LogLevel INFO |
| 27 | # |
| 28 | # Remediation |
| 29 | # ----------- |
| 30 | # Edit the /etc/ssh/sshd_config file to set the parameter as follows: |
| 31 | # |
| 32 | # LogLevel INFO |
| 33 | |
| 34 | parameters: |
| 35 | openssh: |
| 36 | server: |
| 37 | log_level: INFO |
