The initial results compare with the Lynis Incubation: PASS/FAIL Criteria, v1.0 as follows.


IoT Gateway

The Lynis Program Update test MUST pass with no errors.

2022-03-29 22:55:42 Test: Checking for program update...
2022-03-29 22:55:43 Current installed version  : 308
2022-03-29 22:55:43 Latest stable version      : 307
2022-03-29 22:55:43 No Lynis update available.


Fix: Download and run the latest Lynis directly on SUT.

Steps To Implement Security Scan Requirements#InstallandExecute

The following list of tests MUST complete as passing
No.TestResultFix
1Test: Checking PASS_MAX_DAYS option in /etc/login.defsResult: 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
2Performing 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
3Performing 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
4Test: checking for file /etc/network/if-up.d/ntpdateResult: 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
5Performing test ID KRNL-6000 (Check sysctl key pairs in scan profile) :  Following sub-tests requiredN/AN/A
5asysctl 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

6Test: Check if one or more compilers can be found on the systemResult: 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
