system_..._selinux(8)

💫 system_munin_plugin_selinux — the manual, but make it make sense 💫

Okay so bestie, welcome to the system_..._selinux(8) page — this is the Security Enhanced Linux Policy for the system_munin_plugin processes. Buckle up, it's giving security realness. 🎀

---

🌸 NAME 🌸

system_munin_plugin_selinux — Security Enhanced Linux Policy for the system_munin_plugin processes. That's the whole vibe. 💅

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the system_munin_plugin processes via flexible mandatory access control. No cap, it's literally locking things down. 🔒

The system_munin_plugin processes execute with the system_munin_plugin_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. Like, just peek at them, iykyk.

For example:

ps -eZ | grep system_munin_plugin_t

That's it, that's the whole check. Slay. 👑

---

🦋 ENTRYPOINTS 🦋

The system_munin_plugin_t SELinux type can be entered via the system_munin_plugin_exec_t file type. Main character energy only. ✨

The default entrypoint paths for the system_munin_plugin_t domain are the following — and bestie, it's a whole list, so stay with me:

/usr/share/munin/plugins/cpu.*, /usr/share/munin/plugins/if_.*, /usr/share/munin/plugins/nfs.*, /usr/share/munin/plugins/iostat.*, /usr/share/munin/plugins/munin_.*, /usr/share/munin/plugins/acpi, /usr/share/munin/plugins/load, /usr/share/munin/plugins/swap, /usr/share/munin/plugins/forks, /usr/share/munin/plugins/users, /usr/share/munin/plugins/memory, /usr/share/munin/plugins/uptime, /usr/share/munin/plugins/netstat, /usr/share/munin/plugins/threads, /usr/share/munin/plugins/unbound, /usr/share/munin/plugins/irqstats, /usr/share/munin/plugins/proc_pri, /usr/share/munin/plugins/processes, /usr/share/munin/plugins/interrupts, /usr/share/munin/plugins/open_files

That's a lot of paths but they ate and left no crumbs. 🍓

💜 PROCESS TYPES 💜

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

You can see the context of a process using the -Z option to ps. It's giving transparency. 🌈

Policy governs the access confined processes have to files. SELinux system_munin_plugin policy is very flexible, allowing users to setup their system_munin_plugin processes in as secure a method as possible. Secure bestie vibes only. 🔐

The following process types are defined for system_munin_plugin:

system_munin_plugin_t

Note: semanage permissive -a system_munin_plugin_t can be used to make the process type system_munin_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So it's like, you're not getting in trouble, but the system is still writing down everything you do. Not me being observed. 👀💀

---

🧚 BOOLEANS 🧚

SELinux policy is customizable based on least access required. The system_munin_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run system_munin_plugin with the tightest access possible. Tightest access = main character security. ✨

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. Like, it's already on, bestie. 🟢

setsebool -P fips_mode 1

That's the command, keep it close. 💖

---

🌺 MANAGED FILES 🌺

The SELinux process type system_munin_plugin_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 — so don't think you can just waltz in, there are layers. 🧅

• munin_plugin_state_t

/var/lib/munin/plugin-state(/.*)?

• munin_var_lib_t

/var/lib/munin(/.*)?

• system_munin_plugin_tmp_t

That's the whole list, no more, no less. 🙈

---

🌸 FILE CONTEXTS 🌸

SELinux requires files to have an extended attribute to define the file type. It's giving ✨metadata realness✨.

You can see the context of a file using the -Z option to ls. Just peek at it. 👀

Policy governs the access confined processes have to these files. SELinux system_munin_plugin policy is very flexible, allowing users to setup their system_munin_plugin processes in as secure a method as possible. We stan a secure and flexible queen. 👑

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the system_munin_plugin. 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. Like, relocating but make it official. 🏡

semanage fcontext -a -t system_munin_plugin_exec_t '/srv/system_munin_plugin/content(/.*)?'
restorecon -R -v /srv/mysystem_munin_plugin_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies, this one's for you. 💅

The following file types are defined for system_munin_plugin:

system_munin_plugin_exec_t

• Set files with the system_munin_plugin_exec_t type, if you want to transition an executable to the system_munin_plugin_t domain. It's giving "you are what you execute." 🔥

Paths:

/usr/share/munin/plugins/cpu.*, /usr/share/munin/plugins/if_.*,
/usr/share/munin/plugins/nfs.*, /usr/share/munin/plugins/iostat.*,
/usr/share/munin/plugins/munin_.*, /usr/share/munin/plugins/acpi,
/usr/share/munin/plugins/load, /usr/share/munin/plugins/swap,
/usr/share/munin/plugins/forks, /usr/share/munin/plugins/users,
/usr/share/munin/plugins/memory, /usr/share/munin/plugins/uptime,
/usr/share/munin/plugins/netstat, /usr/share/munin/plugins/threads,
/usr/share/munin/plugins/unbound,
/usr/share/munin/plugins/irqstats,
/usr/share/munin/plugins/proc_pri,
/usr/share/munin/plugins/processes,
/usr/share/munin/plugins/interrupts,
/usr/share/munin/plugins/open_files

system_munin_plugin_tmp_t

• Set files with the system_munin_plugin_tmp_t type, if you want to store system munin plugin temporary files in the /tmp directories. Temporary files in /tmp, the classic. 🗂️

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 a quick fix, semanage fcontext is the real commitment. Choose wisely. 💍

---

🌈 COMMANDS 🌈

semanage fcontext can also be used to manipulate default file context mappings. Slay.

semanage permissive can also be used to manipulate whether or not a process type is permissive. Periodt.

semanage module can also be used to enable/disable/install/remove policy modules. The whole toolkit.

semanage boolean can also be used to manipulate the booleans. Flip them like a switch. 🎚️

system-config-selinux is a GUI tool available to customize SELinux policy settings. For the visual learners, we see you. 👩‍💻
