Migrate generic checks from secaudit to cis-hardening new file: 99.3.1_acc_shadow_sha512.sh new file: 99.3.2_acc_sudoers_no_all.sh new file: 99.4_net_fw_default_policy_drop.sh new file: 99.5.1_ssh_auth_pubk_only.sh new file: 99.5.2.1_ssh_cry_kex.sh new file: 99.5.2.2_ssh_cry_mac.sh new file: 99.5.2.3_ssh_cry_rekey.sh new file: 99.5.3_ssh_disable_features.sh new file: 99.5.4_ssh_keys_from.sh new file: 99.5.5_ssh_strict_modes.sh new file: 99.5.6_ssh_sys_accept_env.sh new file: 99.5.7_ssh_sys_no_legacy.sh new file: 99.5.8_ssh_sys_sandbox.sh new file: 99.5.9_ssh_log_level.sh Fix descriptions in comment section for 99.* secaudit checks Remove duplicated legacy services that are already taken care of by vanilla cis Enable custom configuration of checks in config-file, no more hard coded conf Add test to disable check if debian version is too old Add excused IPs while checking "from" field of authorized_keys Escaping dots in IPs Manage Kex for different debian versions Add tests for generic checks and add apply for ssh config Apply shellcheck recommendations on audit/hardening scripts Update script to check for allowed IPs only, remove bastion related Fill `apply` func for ssh config related scripts Add and update tests scenarii Disable shellcheck test for external source 1091 As of today, the entire project is not shellcheck compliant, I prefer disabling the test that warns about not finding external source (that arent compliant). I will enable it again when the project library will be shellchecked https://github.com/koalaman/shellcheck/wiki/SC1091 Refactor password policy check with one check by feature Previous file will now only look for bad passwords in /etc/shadow I added two checks that look for the compliant configuration lines in conf files /etc/logins.defs and /etc/pam.d/common-passwords FIX: merge chained sed and fix regex FIX: update regex to capture more output FIX: fix pattern to ignore commented lines, add apply Also add tests to ensure that commented lines are not detected as valid configuration CHORE: cleanup test situation with file and users removal IMP: add case insensitive option when looking for patterns in files CHORE: removed duplicated line in test file

FIX(tests): change sed in conf file disabled->audit following d6172ad In test cases, changed in sed command "disabled" to "audit" to enable apply part, following this commit d6172ad Change default status disabled -> audit when no conf file 5f28036 - Change default status to audit for file with custom `create_config` (Charles Herlin Thu Feb 14 14:33:21 2019 +0100)
