πŸ’– vnstat_selinux(8) β€” the SELinux glow-up for vnstat πŸ’–

okay bestie, so this is the vnstat_selinux page from the SELinux Policy vnstat manual, and we're about to make SELinux make sense. no cap, it's giving "mandatory access control but make it cute." πŸŽ€


✨ NAME ✨

vnstat_selinux β€” Security Enhanced Linux Policy for the vnstat processes. literally the whole vibe of this page. πŸ¦‹


🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the vnstat processes via flexible mandatory access control. yes bestie, flexible mandatory access control. it's a whole thing. πŸ’…

The vnstat processes execute with the vnstat_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 vnstat_t

periodt. that's how you vibe check your processes. πŸ”₯


πŸšͺ ENTRYPOINTS πŸšͺ

The vnstat_t SELinux type can be entered via the vnstat_exec_t file type.

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

/usr/bin/vnstat

that's the one door in. iconic. πŸ‘‘


πŸ‘― PROCESS TYPES πŸ‘―

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 vnstat policy is very flexible allowing users to setup their vnstat processes in as secure a method as possible. lowkey obsessed with how customizable this is. 🫢

The following process types are defined for vnstat:

vnstat_t, vnstatd_t

Note: semanage permissive -a vnstat_t can be used to make the process type vnstat_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 blocking anything but it's still snitching in the logs. πŸ’€

πŸ”˜ BOOLEANS πŸ”˜

SELinux policy is customizable based on least access required. vnstat policy is extremely flexible and has several booleans that allow you to manipulate the policy and run vnstat with the tightest access possible. we love a "least access required" queen. 🌈

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

slay. secure by default fr fr. ⭐


πŸ“ MANAGED FILES πŸ“

The SELinux process type vnstat_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.

vnstatd_var_lib_t

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

that regex is matching everything under there bestie, no crumbs left. πŸ™ˆ


πŸ—‚οΈ FILE CONTEXTS πŸ—‚οΈ

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

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the vnstat, 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 vnstat_exec_t '/srv/vnstat/content(/.*)?'
restorecon -R -v /srv/myvnstat_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise. 🧚

The following file types are defined for vnstat:

vnstat_exec_t

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

vnstatd_exec_t

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

vnstatd_initrc_exec_t

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

vnstatd_var_lib_t

  • Set files with the vnstatd_var_lib_t type, if you want to store the vnstatd files under the /var/lib directory.

vnstatd_var_run_t

  • Set files with the vnstatd_var_run_t type, if you want to store the vnstatd 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 labels is such a main character energy distinction, don't @ me. πŸ’œ

πŸ› οΈ COMMANDS πŸ› οΈ

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.

that's a whole toolkit bestie, use it wisely. πŸ’…

okay that's the whole page bestie, you ate that. this was vnstat from 26-10-06, version vnstat_selinux(8). go forth and configure securely. πŸ’–πŸ¦‹πŸŒΈ
