✨ nagios_..._selinux(8) — the glow-up edition ✨

okay so bestie, you opened the nagios_..._selinux(8) manual page and honestly? good call. this is the SELinux policy page for the nagios_admin_plugin processes, and we're gonna get you comfy with it 💅

🌸 NAME 🌸

nagios_admin_plugin_selinux — Security Enhanced Linux Policy for the nagios_admin_plugin processes. that's it, that's the whole name. iconique.

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the nagios_admin_plugin processes via flexible mandatory access control. yes, the vibes are locked down and it's for your own good 🫶

The nagios_admin_plugin processes execute with the nagios_admin_plugin_t SELinux type. wanna check if you've got these processes running? run the ps command with the -Z qualifier. fr fr.

For example:

ps -eZ | grep nagios_admin_plugin_t

that's the whole vibe check right there ⭐

---

🎀 ENTRYPOINTS 🎀

The nagios_admin_plugin_t SELinux type can be entered via the nagios_admin_plugin_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/lib/nagios/plugins/check_file_age

one single path and she's serving 🍓

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. lowkey a lotta types, but ok.

You can see the context of a process using the -Z option to ps. cute little detective work 🔍

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

The following process types are defined for nagios_admin_plugin:

• nagios_admin_plugin_t

Note: semanage permissive -a nagios_admin_plugin_t can be used to make the process type nagios_admin_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's not a free pass, the receipts still exist 😭

---

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. nagios_admin_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nagios_admin_plugin with the tightest access possible. tightest access possible = main character energy 🔥

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, go turn that on 💅

---

🧚 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. yes, -Z again, she's everywhere 👑

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the nagios_admin_plugin. 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. like a little makeover but for file labels 💖

semanage fcontext -a -t nagios_admin_plugin_exec_t
'/srv/nagios_admin_plugin/content(/.*)?'
restorecon -R -v /srv/mynagios_admin_plugin_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex era 🌸

The following file types are defined for nagios_admin_plugin:

nagios_admin_plugin_exec_t

• Set files with the nagios_admin_plugin_exec_t type, if you want to transition an executable to the nagios_admin_plugin_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. temporary vs permanent, choose wisely bestie 🙈

🫶 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. a whole GUI, for the visual learners 💅
