🦋 gdomap_selinux(8) — SELinux Policy for gdomap

okay so bestie, you're looking at gdomap_selinux, which is the SELinux policy page for the gdomap processes 💅 this whole thing lives in the SELinux Policy gdomap section, and it's giving "the vibes of your processes, but make it mandatory access control" ✨

🎀 NAME 🎀

gdomap_selinux — Security Enhanced Linux Policy for the gdomap processes 💖

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the gdomap processes via flexible mandatory access control. like, it's not optional, it's not vibes-based, it's the policy 😌

The gdomap processes execute with the gdomap_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier 🫶

For example:

ps -eZ | grep gdomap_t

that's it, that's the vibe check 🔍

⭐ ENTRYPOINTS ⭐

The gdomap_t SELinux type can be entered via the gdomap_exec_t file type 👑

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

/usr/bin/gdomap

one path. one icon. no cap 💅

🔥 PROCESS TYPES 🔥

SELinux defines process types (domains) for each process running on the system ✨

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

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

The following process types are defined for gdomap:

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

💜 BOOLEANS 💜

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

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

three booleans, all iconic, all doing their own little thing 🎀

🌈 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 gdomap policy is very flexible, allowing users to setup their gdomap processes in as secure a method as possible 🫶

The following port types are defined for gdomap:

  • gdomap_port_t

Default Defined Ports:

tcp 538
udp 538

538 for both, because consistency is main character energy 💅

🧚 MANAGED FILES 🧚

The SELinux process type gdomap_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. like, SELinux isn't gonna override DAC for you, bestie 🙈

🍓 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 gdomap policy is very flexible, allowing users to setup their gdomap processes in as secure a method as possible ✨

💖 STANDARD FILE CONTEXT 💖

SELinux defines the file context types for the gdomap. 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 🎯

semanage fcontext -a -t gdomap_exec_t '/srv/gdomap/content(/.*)?'
restorecon -R -v /srv/mygdomap_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 gdomap:

  • gdomap_conf_t — Set files with the gdomap_conf_t type, if you want to treat the files as gdomap configuration data, usually stored under the /etc directory. 📁
  • gdomap_exec_t — Set files with the gdomap_exec_t type, if you want to transition an executable to the gdomap_t domain. 🚀
  • gdomap_initrc_exec_t — Set files with the gdomap_initrc_exec_t type, if you want to transition an executable to the gdomap_initrc_t domain. 🌀
  • gdomap_var_run_t — Set files with the gdomap_var_run_t type, if you want to store the gdomap files under the /run or /var/run directory. 🏃‍♀️
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. no takebacks with chcon, sorry 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 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 🖥️✨
