💅 MAIL_MUNIN_PLUGIN_SELINUX(8) 💅

okay bestie, welcome to the mail_munin_plugin_selinux page — section 8 of the manual, and literally the glow-up your mail munin plugin processes deserve ✨

🎀 NAME 🎀

mail_munin_plugin_selinux — the Security Enhanced Linux Policy for the mail_munin_plugin processes. she's the one keeping those processes in check, no cap 💅

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the mail_munin_plugin processes via flexible mandatory access control. like, flexible but also mandatory, which is giving "my rules but make it fashion" 💖

The mail_munin_plugin processes execute with the mail_munin_plugin_t SELinux type. wanna check if you've got these processes running? run the ps command with the -Z qualifier, easy peasy 🫶

For example:

ps -eZ | grep mail_munin_plugin_t

🦋 ENTRYPOINTS 🦋

The mail_munin_plugin_t SELinux type can be entered via the mail_munin_plugin_exec_t file type. that's the doorway, iykyk 🚪✨

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

/usr/share/munin/plugins/qmail.*, /usr/share/munin/plugins/exim_mail.*,
/usr/share/munin/plugins/sendmail_.*,
/usr/share/munin/plugins/courier_mta_.*,
/usr/share/munin/plugins/postfix_mail.*,
/usr/share/munin/plugins/mailman, /usr/share/munin/plugins/mailscanner

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every process gets its own little domain, main character energy for everyone 🎀

You can see the context of a process using the -Z option to ps.

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

The following process types are defined for mail_munin_plugin:

  • mail_munin_plugin_t
Note: semanage permissive -a mail_munin_plugin_t can be used to make the process type mail_munin_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she won't block you, but she WILL be taking notes 📝👀

✨ BOOLEANS ✨

SELinux policy is customizable based on least access required. mail_munin_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mail_munin_plugin with the tightest access possible. mix and match, set your boundaries, we stan 🌈

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 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 mail_munin_plugin_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. note bestie: the processes UID still need to have DAC permissions — SELinux isn't doing all the work for you 😭

krb5_host_rcache_t

/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

mail_munin_plugin_tmp_t — listed with no default paths, she's mysterious like that 🙈

munin_plugin_state_t

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

munin_var_lib_t

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

💀 FILE CONTEXTS 💀

SELinux requires files to have an extended attribute to define the file type. literally the file's whole identity, and honestly? iconic 💅

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 mail_munin_plugin policy is very flexible allowing users to setup their mail_munin_plugin processes in as secure a method as possible. yes we said this already, it's still true, periodt 🔥

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the mail_munin_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. relocate your files AND keep the labels? slay 🎀

semanage fcontext -a -t mail_munin_plugin_exec_t
'/srv/mail_munin_plugin/content(/.*)?'
restorecon -R -v /srv/mymail_munin_plugin_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🌸

The following file types are defined for mail_munin_plugin:

  • mail_munin_plugin_exec_t — Set files with the mail_munin_plugin_exec_t type, if you want to transition an executable to the mail_munin_plugin_t domain.

Paths:

/usr/share/munin/plugins/qmail.*,
/usr/share/munin/plugins/exim_mail.*,
/usr/share/munin/plugins/sendmail_.*,
/usr/share/munin/plugins/courier_mta_.*,
/usr/share/munin/plugins/postfix_mail.*,
/usr/share/munin/plugins/mailman,
/usr/share/munin/plugins/mailscanner
  • mail_munin_plugin_tmp_t — Set files with the mail_munin_plugin_tmp_t type, if you want to store mail munin plugin temporary files in the /tmp directories. temp files but make them labeled ✨
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, know the difference bestie — chcon is the fling, semanage fcontext is the whole relationship 💖

🌈 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 🖥️✨
