💅 ricci_modclusterd_selinux(8) — the glow-up version

okay so bestie, welcome to ricci_modclusterd_selinux(8), the manual page for the SELinux policy that keeps the ricci_modclusterd processes in check. yes, it's a whole thing, and yes, we're gonna get through it together 💖

✨ NAME ✨

ricci_modclusterd_selinux — Security Enhanced Linux Policy for the ricci_modclusterd processes. that's it. that's the vibe. 🎀

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the ricci_modclusterd processes via flexible mandatory access control. flexin' on 'em fr fr.

The ricci_modclusterd processes execute with the ricci_modclusterd_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 ricci_modclusterd_t

slay, now you know what's running 👑

🚪 ENTRYPOINTS 🚪

The ricci_modclusterd_t SELinux type can be entered via the ricci_modclusterd_exec_t file type.

The default entrypoint paths for the ricci_modclusterd_t domain are literally these:

/usr/bin/modclusterd

one path, one icon 💅

🧚 PROCESS TYPES 🧚

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

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

Policy governs the access confined processes have to files. SELinux ricci_modclusterd policy is very flexible allowing users to setup their ricci_modclusterd processes in as secure a method as possible. highkey generous of it.

The following process types are defined for ricci_modclusterd:

  • ricci_modcluster_t
  • ricci_modclusterd_t
Note: semanage permissive -a ricci_modclusterd_t can be used to make the process type ricci_modclusterd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it stops blocking you but it still talks about you 😭 the AVC receipts never stop.

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. ricci_modclusterd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ricci_modclusterd with the tightest access possible. customize your girl's boundaries, periodt.

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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

see, not so scary. three booleans, three little switches 🌸

🌈 PORT TYPES 🌈

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for ricci_modclusterd:

  • ricci_modcluster_port_t

Default Defined Ports:

tcp 16851
udp 16851

both protocols, same number, coordinated queen 💜

🗂️ MANAGED FILES 🗂️

The SELinux process type ricci_modclusterd_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. SELinux said "i'll handle the labels, you handle the perms" 🙈

🏷️ 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.

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the ricci_modclusterd. 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. relocating? valid. relabeling? mandatory 😌

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

The following file types are defined for ricci_modclusterd:

ricci_modclusterd_exec_t

  • Set files with the ricci_modclusterd_exec_t type, if you want to transition an executable to the ricci_modclusterd_t domain. it's giving doorway energy.

ricci_modclusterd_tmpfs_t

  • Set files with the ricci_modclusterd_tmpfs_t type, if you want to store ricci modclusterd files on a tmpfs file system. tmpfs = speedy little home for your files 🌸
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, it matters 💀

💻 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 port can also be used to manipulate the port definitions.
  • 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 graphical era 👑
