πŸ’– systemd_localed_selinux πŸ’–

okay bestie, so this is the systemd_localed_selinux(8) manual page and it's literally all about the SELinux policy for the systemd_localed processes. no cap, it's giving security realness and i'm obsessed πŸŽ€


✨ NAME ✨

systemd_localed_selinux β€” Security Enhanced Linux Policy for the systemd_localed processes πŸ‘‘


🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the systemd_localed processes via flexible mandatory access control. it's giving bodyguard energy fr fr πŸ’…

The systemd_localed processes execute with the systemd_localed_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. vibe check time πŸ”

For example:

ps -eZ | grep systemd_localed_t

πŸ¦‹ ENTRYPOINTS πŸ¦‹

The systemd_localed_t SELinux type can be entered via the systemd_localed_exec_t file type. that's the main character energy right there ✨

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

/usr/lib/systemd/systemd-localed

πŸŽ€ PROCESS TYPES πŸŽ€

SELinux defines process types (domains) for each process running on the system. lowkey iconic how it just categorizes everything πŸ’œ

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_localed policy is very flexible allowing users to setup their systemd_localed processes in as secure a method as possible. slay πŸ”₯

The following process types are defined for systemd_localed:

  • systemd_localed_t
Note: semanage permissive -a systemd_localed_t can be used to make the process type systemd_localed_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. it's giving "i'm not mad, just disappointed" energy 😭

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. systemd_localed policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_localed with the tightest access possible. bestie, these are the switches you can flip πŸ’…

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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 allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

πŸ“ MANAGED FILES πŸ“

The SELinux process type systemd_localed_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions. it's a whole list bestie, buckle up 🎒

πŸ’€ FILE CONTEXTS πŸ’€

SELinux requires files to have an extended attribute to define the file type. it's literally metadata for your files, no cap πŸ“

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_localed policy is very flexible allowing users to setup their systemd_localed processes in as secure a method as possible. we love a flexible queen πŸ’–

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the systemd_localed, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. it's a whole process bestie 🫢

semanage fcontext -a -t systemd_localed_exec_t '/srv/systemd_localed/content(/.*)?'
restorecon -R -v /srv/mysystemd_localed_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex is giving "i contain multitudes" energy ✨

The following file types are defined for systemd_localed:

  • systemd_localed_exec_t β€” Set files with the systemd_localed_exec_t type, if you want to transition an executable to the systemd_localed_t domain. it's giving transformation era πŸ’…
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. temporary vs permanent β€” choose wisely πŸ™ˆ

🧚 COMMANDS 🧚

Semanage fcontext can also be used to manipulate default file context mappings. periodt πŸ’…

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. it's giving modular realness πŸ”₯

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings. for the visual learners, we see you πŸ‘€
