systemd_..._selinux(8)

okay bestie, welcome to the systemd_..._selinux(8) manual page — the SELinux Policy systemd_homework page — and we're getting into it 💅✨

🌸 NAME 🌸

systemd_homework_selinux — Security Enhanced Linux Policy for the systemd_homework processes 🫶

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the systemd_homework processes via flexible mandatory access control. no cap, that's the whole vibe 💖

The systemd_homework processes execute with the systemd_homework_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep systemd_homework_t

🎀 ENTRYPOINTS 🎀

The systemd_homework_t SELinux type can be entered via the user_home_t, systemd_homework_exec_t file types.

The default entrypoint paths for the systemd_homework_t domain are the following:

• /home/[^/]+/.+
• /usr/lib/systemd/systemd-homework

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system — yes, every process gets a little domain moment 💫

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux systemd_homework policy is very flexible, allowing users to setup their systemd_homework processes in as secure a method as possible. 🫶

The following process types are defined for systemd_homework:

• systemd_homework_t

Note: semanage permissive -a systemd_homework_t can be used to make the process type systemd_homework_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. 😭

💖 BOOLEANS 💖

SELinux policy is customizable based on least access required. systemd_homework policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_homework with the tightest access possible. ✨

• If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

• If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Enabled by default.

setsebool -P use_nfs_home_dirs 1

• If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

setsebool -P use_samba_home_dirs 1

🌈 MANAGED FILES 🌈

The SELinux process type systemd_homework_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions. 🔥

• cifs_t
• ecryptfs_t
  • /home/[^/]+/.Private(/.*)?
  • /home/[^/]+/.ecryptfs(/.*)?
• fsadm_var_run_t
  • /run/fsck(/.*)?
  • /run/blkid(/.*)?
• fusefs_t
  • /run/user/[0-9]+/gvfs
• lvm_var_run_t
  • /run/lvm(/.*)?
  • /run/dmevent.*
  • /run/storaged(/.*)?
  • /run/cryptsetup(/.*)?
  • /run/multipathd(/.*)?
  • /run/multipathd.sock
• nfs_t
• systemd_homed_cache_t
  • /var/cache/systemd/home(/.*)?
• systemd_homed_tmpfs_t
• unlabeled_t
• user_home_type
  • all user home files

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. 🎀

You can see the context of a file using the -Z option to ls.

Policy governs the access confined processes have to these files. SELinux systemd_homework policy is very flexible, allowing users to setup their systemd_homework processes in as secure a method as possible. 💜

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for systemd_homework; if you want to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t systemd_homework_exec_t
'/srv/systemd_homework/content(/.*)?'
restorecon -R -v /srv/mysystemd_homework_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. 💅

The following file types are defined for systemd_homework:

• systemd_homework_exec_t

Set files with the systemd_homework_exec_t type, if you want to transition an executable to the systemd_homework_t domain.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. 🫡

⭐ COMMANDS ⭐

• semanage fcontext can also be used to manipulate default file context mappings.
• semanage permissive can also be used to manipulate whether or not a process type is permissive.
• semanage module can also be used to enable/disable/install/remove policy modules.
• semanage boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings.
