amtu_selinux(8)

✨ amtu_selinux — the SELinux glow-up for your amtu processes ✨

Okay so bestie, this is the manual page for amtu_selinux — it's the SELinux Policy that keeps the amtu processes in check. Think of it as the main character energy that secures your amtu processes via flexible mandatory access control. 💅

---

🎀 DESCRIPTION 🎀

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

The amtu processes execute with the amtu_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 amtu_t

Lowkey iconic, right? 🦋

---

🌸 ENTRYPOINTS 🌸

The amtu_t SELinux type can be entered via the amtu_exec_t file type. That's the gateway, the door, the entrypoint to the whole situation.

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

/usr/bin/amtu

Periodt. That's the only one. 💖

---

🌈 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 amtu policy is very flexible, allowing users to setup their amtu processes in as secure a method as possible. It's giving "I got you, bestie." 🫶

The following process types are defined for amtu:

• amtu_t

Note: semanage permissive -a amtu_t can be used to make the process type amtu_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's chill but it still snitches in the logs. 😭

---

🔥 BOOLEANS 🔥

SELinux policy is customizable based on least access required. amtu policy is extremely flexible and has several booleans that allow you to manipulate the policy and run amtu with the tightest access possible. We love a customizable queen. 👑

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

Slay. That's the whole boolean section. 💀

---

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. It's like a little name tag but for security. 🏷️

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 amtu policy is very flexible, allowing users to setup their amtu processes in as secure a method as possible. Same energy as before — very accommodating, very secure. ✨

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the amtu. If you wanted 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 amtu_exec_t '/srv/amtu/content(/.*)?'
restorecon -R -v /srv/myamtu_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies, rise up. 🍓

The following file types are defined for amtu:

• amtu_exec_t — Set files with the amtu_exec_t type, if you want to transition an executable to the amtu_t domain. This is the one that gets you into the amtu_t party. 💅
• amtu_initrc_exec_t — Set files with the amtu_initrc_exec_t type, if you want to transition an executable to the amtu_initrc_t domain. Different type, different domain, same slay. 🔥

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. So like, chcon is the quick fix, semanage fcontext + restorecon is the committed relationship. Choose wisely. 😭

👑 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. For the girlies who prefer a little visual moment. 🎀
