- "users_homedir_is_configured.sh" is a concatenation of different existing scripts:
- [users_homedir_exist.sh](https://github.com/ovh/debian-cis/blob/master/bin/hardening/users_homedir_exist.sh)
- [users_homedir_ownership.sh](https://github.com/ovh/debian-cis/blob/master/bin/hardening/users_homedir_ownership.sh)
- [check_user_dir_perm.sh](https://github.com/ovh/debian-cis/blob/master/bin/hardening/check_user_dir_perm.sh)
And so is its test
It will be mapped as 7.2.9 for debian 12
- The following scripts are a split from [5.3.1_enable_pwquality.sh](https://github.com/ovh/debian-cis/blob/master/bin/hardening/enable_pwquality.sh):
- enable_libpam_pwquality.sh -> will be mapped as 5.3.2.3
- install_libpam_pwquality.sh -> will be mapped as 5.3.1.3
- password_complexity.sh -> will be mapped as 5.3.3.2.3
- password_min_length.sh -> will be mapped as 5.3.3.2.2
The others are scripts are new.
They will be mapped as follow for debian 12 CIS :
- apt_gpg_is_configured.sh -> 1.2.1.1
- dev_shm_separate_partition.sh -> 1.2.2.1
- install_iptables.sh -> 4.3.1.1
- install_nftables.sh -> 4.2.1
- password_consecutive_characters.sh -> 5.3.3.2.4
- password_max_sequential_characters.sh -> 5.3.3.2.5
