Akarino Test Group Information

...

The test script will start the registry, pull upstream images and populate the registry, clean images left over from the pull process, stop the registry, and remove the registry. The robot command should report success for all test cases.

Pass (5/5 test cases)

CI/CD Regression Tests: Node Setup

...

The test scripts will initialize the master and edge nodes and verify the required software is installed. The robot command should report success for all test cases.

Feature Project Tests

...

We use Ubuntu 20.04, so we ran Vuls test as follows:

Create directory

$ mkdir ~/vuls
$ cd ~/vuls
$ mkdir go-cve-dictionary-log goval-dictionary-log gost-log

Fetch NVD

$ docker run --rm -it \
    -v $PWD:/go-cve-dictionary \
    -v $PWD/go-cve-dictionary-log:/var/log/go-cve-dictionary \
    vuls/go-cve-dictionary fetch nvd

Fetch OVAL

$ docker run --rm -it \
     -v $PWD:/goval-dictionary \
     -v $PWD/goval-dictionary-log:/var/log/goval-dictionary \
     vuls/goval-dictionary fetch ubuntu 16 17 18 19 20

Fetch gost

$ docker run --rm -i \
     -v $PWD:/gost \
     -v $PWD/gost-log:/var/log/gost \
     vuls/gost fetch ubuntu

Create config.toml

[servers]

[servers.master]
host = "192.168.51.22"
port = "22"
user = "test-user"
sshConfigPathkeyPath   = "/root/.ssh/config"
keyPath = "/root/.ssh/id_rsa"id_rsa" # path to ssh private key in docker

Start vuls container to run tests

$ docker run --rm -it \
    -v ~/.ssh:/root/.ssh:ro \
    -v $PWD:/vuls \
    -v $PWD/vuls-log:/var/log/vuls \
    -v /etc/localtime:/etc/localtime:ro \
    -v /etc/timezone:/etc/timezone:ro \
    vuls/vuls scan \
    -config=./config.toml

Get the report

$ docker run --rm -it \
     -v ~/.ssh:/root/.ssh:ro \
     -v $PWD:/vuls \
     -v $PWD/vuls-log:/var/log/vuls \

Lynis

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

...

No.	Test	Result	Fix
1	Test: Checking PASS_MAX_DAYS option in /etc/login.defs	Result: password minimum age is not configured Suggestion: Configure minimum password age in /etc/login.defs [test:AUTH-9286]	Set PASS_MAX_DAYS 180 in /etc/login.defs
2	Performing test ID AUTH-9328 (Default umask values)	Result: found umask 022, which could be improved Suggestion: Default umask in /etc/login.defs could be more strict like 027 [test:AUTH-9328]	Set UMASK 027 in /etc/login.defs
3	Performing test ID SSH-7440 (Check OpenSSH option: AllowUsers and AllowGroups)	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).	Configure AllowUsers in /etc/ssh/sshd_config
4	Test: checking for file /etc/network/if-up.d/ntpdate	Test: checking for file /etc/network/if-up.d/ntpdate Result: file /etc/network/if-up.d/ntpdate does not exist ... Hardening: assigned maximum number of hardening points for this item (3).	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	Set recommended value in /etc/sysctl.d/90-lynis-hardening.conf and disable apport in /etc/default/apport
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
5c	sysctl key net.ipv4.conf.default.accept_source_route contains equal expected and current value (0)	Result: sysctl key net.inetipv4.ip.sourceroute does not exist on this machine ... Hardening: assigned maximum number of hardening points for this item (1) 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.confOK
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 /usr/bin/grep to filter on 'compiler' Hardening: assigned partial number of hardening points (1 of 3).	Uninstall gcc and remove /usr/bin/as (installed with binutils)

...

The following list of tests MUST complete as passing

No.	Test	Result
1	Test: Checking PASS_MAX_DAYS option in /etc/login.defs	Result: max password age is 180 days Hardening: assigned maximum number of hardening points for this item (3).
2	Performing test ID AUTH-9328 (Default umask values)	Result: umask is 027, which is fine Hardening: assigned maximum number of hardening points for this item (2).
3	Performing test ID SSH-7440 (Check OpenSSH option: AllowUsers and AllowGroups)	Result: SSH is limited to a specific set of users, which is good Hardening: assigned maximum number of hardening points for this item (2).
5a	sysctl key fs.suid_dumpable contains equal expected and current value (0)	Result: sysctl key fs.
