πŸ’… nagios_script_selinux β€” the SELinux policy page for your nagios_script processes (8)

okay so bestie, this is nagios_script_selinux(8), and it's literally the whole scoop on how SELinux handles the nagios_script processes. settle in, grab a lil strawberry πŸ“ drink, we're getting into it.


✨ NAME ✨

nagios_script_selinux β€” the Security Enhanced Linux Policy for the nagios_script processes. that's the whole name, no notes. πŸŽ€


🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the nagios_script processes via flexible mandatory access control. like, it's giving bodyguard energy but for processes. πŸ’…

The nagios_script processes execute with the nagios_script_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier. easy.

For example:

ps -eZ | grep nagios_script_t

go off, ps. πŸ‘‘


πŸ¦‹ ENTRYPOINTS πŸ¦‹

The nagios_script_t SELinux type can be entered via the nagios_script_exec_t file type. that's the doorway, bestie, no cap.

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

  • /usr/lib/icinga/cgi(/.*)?
  • /usr/lib/nagios/cgi(/.*)?
  • /usr/lib/cgi-bin/nagios(/.+)?
  • /usr/lib/nagios/cgi-bin(/.*)?
  • /usr/lib/cgi-bin/netsaint(/.*)?

πŸ”₯ PROCESS TYPES πŸ”₯

SELinux defines process types (domains) for each process running on the system. yes, 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. πŸ’–

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

The following process types are defined for nagios_script:

  • nagios_script_t
Note: semanage permissive -a nagios_script_t can be used to make the process type nagios_script_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, it's more of a "we see you but we're not stopping you" vibe. πŸ‘€

πŸŽ€ BOOLEANS πŸŽ€

SELinux policy is customizable based on least access required β€” the tightest possible leash, basically. nagios_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nagios_script with the tightest access possible. slay for least privilege. ✨

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 httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default.

setsebool -P httpd_enable_cgi 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

🧚 MANAGED FILES 🧚

The SELinux process type nagios_script_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. and note: the process's UID still needs to have DAC permissions, so don't come crying to SELinux about that part, it's not its job. 😭

  • nagios_rw_content_t

πŸ’œ FILE CONTEXTS πŸ’œ

SELinux requires files to have an extended attribute to define the file type. it's the lil name tag every file wears to the party. πŸŽ€

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_script policy is very flexible, allowing users to setup their nagios_script processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for nagios_script. so 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. two-step process, bestie, don't skip the second one.

semanage fcontext -a -t nagios_script_exec_t '/srv/nagios_script/content(/.*)?'
restorecon -R -v /srv/mynagios_script_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_script:

nagios_script_exec_t

  • Set files with the nagios_script_exec_t type, if you want to transition an executable to the nagios_script_t domain.

Paths:

  • /usr/lib/icinga/cgi(/.*)?
  • /usr/lib/nagios/cgi(/.*)?
  • /usr/lib/cgi-bin/nagios(/.+)?
  • /usr/lib/nagios/cgi-bin(/.*)?
  • /usr/lib/cgi-bin/netsaint(/.*)?
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. chcon is the cute temporary tattoo, semanage fcontext + restorecon is the real ink. πŸ™ˆ

πŸ‘‘ COMMANDS πŸ‘‘

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 girlies. πŸ’…
