✨ nagios_checkdisk_plugin_selinux(8) ✨

okay bestie, so this is the nagios...selinux(8) page — yes that manual name with the three dots is iconic and yes it's staying — and it's all about the SELinux policy for the nagios_checkdisk_plugin processes. let's get into it 💅

🌸 NAME 🌸

nagios_checkdisk_plugin_selinux — the Security Enhanced Linux Policy for the nagios_checkdisk_plugin processes. that's it, that's the whole name, she's compact and she knows it 🫶

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the nagios_checkdisk_plugin processes via flexible mandatory access control. no cap, that's the whole flex.

The nagios_checkdisk_plugin processes execute with the nagios_checkdisk_plugin_t SELinux type. wanna check if you've got these processes running rn? just run the ps command with the -Z qualifier, like:

ps -eZ | grep nagios_checkdisk_plugin_t

literally that easy, slay 💖

🎀 ENTRYPOINTS 🎀

The nagios_checkdisk_plugin_t SELinux type can be entered via the nagios_checkdisk_plugin_exec_t file type. that's the doorway, bestie.

The default entrypoint paths for the nagios_checkdisk_plugin_t domain are, exactly:

• /usr/lib/nagios/plugins/check_disk
• /usr/lib/nagios/plugins/check_disk_smb
• /usr/lib/nagios/plugins/check_ide_smart
• /usr/lib/nagios/plugins/check_linux_raid

those four, in that order, periodt 🙈

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. so every process gets its own lil identity, main character energy fr fr.

you can see the context of a process using the -Z option to ps 🔍

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

The following process types are defined for nagios_checkdisk_plugin:

• nagios_checkdisk_plugin_t

Note: semanage permissive -a nagios_checkdisk_plugin_t can be used to make the process type nagios_checkdisk_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she's chill but she's still taking notes 📝

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. the nagios_checkdisk_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nagios_checkdisk_plugin with the tightest access possible. tightest access = the vibe.

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

go off, fips_mode 💀

⭐ FILE CONTEXTS ⭐

SELinux requires files to have an extended attribute to define the file type. yeah, files have labels now, it's giving organized 🎀

you can see the context of a file using the -Z option to ls ✨

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

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the nagios_checkdisk_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 this:

semanage fcontext -a -t nagios_checkdisk_plugin_exec_t '/srv/nagios_checkdisk_plugin/content(/.*)?'
restorecon -R -v /srv/mynagios_checkdisk_plugin_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies stay winning 💅

The following file types are defined for nagios_checkdisk_plugin:

nagios_checkdisk_plugin_exec_t

• set files with the nagios_checkdisk_plugin_exec_t type if you want to transition an executable to the nagios_checkdisk_plugin_t domain. that's the transition pipeline, iykyk 🔥

Paths:

/usr/lib/nagios/plugins/check_disk,
/usr/lib/nagios/plugins/check_disk_smb,
/usr/lib/nagios/plugins/check_ide_smart,
/usr/lib/nagios/plugins/check_linux_raid

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, bestie, know the difference 😭

💜 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. yes, a GUI, for the visual learners 🖥️✨
