💅 conntrackd_selinux — the SELinux glow-up for conntrackd ✨

okay bestie, so this is the <pink>conntrackd_selinux</pink> page from the SELinux Policy conntrackd manual — yes, section 8, we love a section 8 moment 🎀

✨ NAME ✨

conntrackd_selinux — the Security Enhanced Linux Policy for the conntrackd processes 🫶

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the conntrackd processes via flexible mandatory access control. no cap, that's literally its whole job 💅

The conntrackd processes execute with the conntrackd_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier. it's giving detective energy 🔍

For example:

ps -eZ | grep conntrackd_t

🦋 ENTRYPOINTS 🦋

The conntrackd_t SELinux type can be entered via the conntrackd_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/bin/conntrackd

👑 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 conntrackd policy is very flexible allowing users to setup their conntrackd processes in as secure a method as possible. highkey iconic behavior 🔥

The following process types are defined for conntrackd:

conntrackd_t
Note: semanage permissive -a conntrackd_t can be used to make the process type conntrackd_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 but it's still snitching 💀

🍓 BOOLEANS 🍓

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

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

🌈 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 conntrackd policy is very flexible allowing users to setup their conntrackd processes in as secure a method as possible ✨

The following port types are defined for conntrackd:

conntrackd_port_t

Default Defined Ports:

udp 3780

💖 MANAGED FILES 💖

The SELinux process type conntrackd_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. yes, SELinux isn't doing everything for you, go touch some DAC 😭

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. it's giving "everything has a label, bestie" 🏷️

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

💜 STANDARD FILE CONTEXT 💜

SELinux defines the file context types for the conntrackd, 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. relabeling era, we love to see it 🔥

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

The following file types are defined for conntrackd:

conntrackd_conf_t

  • Set files with the conntrackd_conf_t type, if you want to treat the files as conntrackd configuration data, usually stored under the /etc directory.

conntrackd_exec_t

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

conntrackd_initrc_exec_t

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

conntrackd_log_t

  • Set files with the conntrackd_log_t type, if you want to treat the data as conntrackd log data, usually stored under the /var/log directory.

conntrackd_unit_file_t

  • Set files with the conntrackd_unit_file_t type, if you want to treat the files as conntrackd unit content.

conntrackd_var_lock_t

  • Set files with the conntrackd_var_lock_t type, if you want to treat the files as conntrackd var lock data, stored under the /var/lock directory

conntrackd_var_run_t

  • Set files with the conntrackd_var_run_t type, if you want to store the conntrackd 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. temporary vs permanent, know the difference 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. a whole GUI, fancy 🎀
