Lynis
Nexus URL TBD
The initial results compare with the Lynis Incubation: PASS/FAIL Criteria, v1.0 as follows.
...
The following list of tests MUST complete as passing
| No. | Test | Result | Fix |
|---|---|---|---|
| 1 | Test: Checking PASS_MAX_DAYS option in /etc/login.defs | Result: password aging limits are not configured Suggestion: Configure maximum password age in /etc/login.defs [test:AUTH-9286] [details:-] [solution:-] Hardening: assigned partial number of hardening points (0 of 1). Currently having 13 points (out of 28) | Set PASS_MAX_DAYS 180 in /etc/login.defs |
| 2 | Performing test ID AUTH-9328 (Default umask values) | Test: Checking umask value in /etc/login.defs Result: found umask 022, which could be improved Suggestion: Default umask in /etc/ |
| login.defs could be more strict like 027 [test:AUTH-9328] [details:-] [solution:-] | Set UMASK 027 in /etc/login.defs |
| 3 | Performing test ID SSH-7440 (Check OpenSSH option: AllowUsers and AllowGroups) | Result: AllowUsers is not set Result: AllowGroups is not set Result: SSH has no specific user or group limitation. Most likely all valid users can SSH to this machine. Hardening: assigned partial number of hardening points (0 of 1). Currently having 140 points (out of 217) Security check: file is normal Checking permissions of /home/ubuntu/lynis/include/tests_snmp File permissions are OK | Configure AllowUsers, AllowGroups in /etc/ssh/sshd_config |
| 4 | Test: checking for file /etc/network/if-up.d/ntpdate | Result: file /etc/network/if-up.d/ntpdate does not exist Result: Found a time syncing daemon/client. Hardening: assigned maximum number of hardening points for this item (3). Currently having 149 points (out of 232) | OK |
| 5 | Performing test ID KRNL-6000 (Check sysctl key pairs in scan profile) : Following sub-tests required | N/A | N/A |
| 5a | sysctl key fs.suid_dumpable contains equal expected and current value (0) | Result: sysctl key fs.suid_dumpable has a different value than expected in scan profile. Expected=0, Real=2 Hardening: assigned partial number of hardening points (0 of 1). Currently having 151 points (out of 247) | Set recommended value in /etc/sysctl.d/90-lynis-hardening.conf echo 'fs.suid_dumpable=0' | sudo tee -a /etc/sysctl.d/90-lynis-hardening.conf sudo /sbin/sysctl --system sudo sysctl -a |grep suid |
| 5b | sysctl key kernel.dmesg_restrict contains equal expected and current value (1) | Result: sysctl key kernel.dmesg_restrict has a different value than expected in scan profile. Expected=1, Real=0 | Set recommended value in /etc/sysctl.d/90-lynis-hardening.conf echo 'kernel.dmesg_restrict=1' | sudo tee -a /etc/sysctl.d/90-lynis-hardening.conf sudo /sbin/sysctl --system sudo sysctl -a |grep dmesg |
| 5c | sysctl key net.ipv4.conf.default.accept_source_route contains equal expected and current value (0) | Result: sysctl key net.ipv4.conf.default.accept_source_route has a different value than expected in scan profile. Expected=0, Real=1 | Set recommended value in /etc/sysctl.d/90-lynis-hardening.conf echo 'net.ipv4.conf.default.accept_source_route=0' | sudo tee -a /etc/sysctl.d/90-lynis-hardening.conf sudo /sbin/sysctl --system sudo sysctl -a |grep ipv4.conf.default.accept_source_route |
| 6 | Test: Check if one or more compilers can be found on the system | Result: found installed compiler. See top of logfile which compilers have been found or use /bin/grep to filter on 'compiler' Hardening: assigned partial number of hardening points (1 of 3). Currently having 168 points (out of 280) | Uninstall gcc and remove /usr/bin/as |
