✨ secadm_su_selinux(8) ✨

okay bestie, welcome to the secadm_su_selinux manual page — it's the SELinux Policy page for all things secadm_su, and yes, the manual name is literally secadm_su_selinux(8) so now you know 🫶

---

💖 NAME 💖

secadm_su_selinux — literally the Security Enhanced Linux Policy for the secadm_su processes, no cap.

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the secadm_su processes via flexible mandatory access control. it's giving security, it's giving structure, we love to see it 💅

The secadm_su processes execute with the secadm_su_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 secadm_su_t

that's it, that's the vibe check 🔍

---

🦋 ENTRYPOINTS 🦋

The secadm_su_t SELinux type can be entered via the su_exec_t file type.

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

/usr/(local/)?bin/ksu, /usr/bin/su, /usr/bin/kdesu

those are the doors, bestie — memorize them 🚪✨

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system.

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

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

The following process types are defined for secadm_su:

• secadm_su_t
• secadm_sudo_t

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

so like — permissive means it won't block you, but it's still taking notes 📝👀

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. secadm_su policy is extremely flexible and has several booleans that allow you to manipulate the policy and run secadm_su 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 allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

setsebool -P kerberos_enabled 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

three booleans, three little switches, iconic behavior honestly ⭐

🍓 MANAGED FILES 🍓

The SELinux process type secadm_su_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.

/var/log/btmp.*
/run/faillock(/.*)?
/var/log/faillog.*
/var/log/tallylog.*

initrc_var_run_t

/run/sysconfig(/.*)?
/run/utmp
/run/keymap
/run/numlock-on
/run/setleds-on

look at all those paths, she's thorough, she's organized, she ate 💀✨

🌈 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.

four semanage subcommands and a GUI — pick your fighter 🥊
