afterburn_selinux(8)

✨ afterburn_selinux ✨

okay so bestie, this is the SELinux policy page for the afterburn processes, and it's literally gonna teach you how to keep things secure without losing your mind 💅

---

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the afterburn processes via flexible mandatory access control. no cap, it's giving protective bestie energy 🫶

The afterburn processes execute with the afterburn_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 afterburn_t

---

🚪 ENTRYPOINTS 🚪

The afterburn_t SELinux type can be entered via the afterburn_exec_t file type.

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

/usr/bin/afterburn

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. iconic behavior tbh 🌈

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

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

The following process types are defined for afterburn:

afterburn_t

Note: semanage permissive -a afterburn_t can be used to make the process type afterburn_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. it's like, still watching you, just not blocking you, iykyk 🙈

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. afterburn policy is extremely flexible and has several booleans that allow you to manipulate the policy and run afterburn with the tightest access possible. slay for granular control fr fr ✨

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

📁 MANAGED FILES 📁

The SELinux process type afterburn_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. okay so this is the whole list, don't skip it bestie 💖

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. it's literally the vibe check for your files 🦋

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the afterburn, 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. it's giving "relabeling era" 💅

semanage fcontext -a -t afterburn_exec_t '/srv/afterburn/content(/.*)?'
restorecon -R -v /srv/myafterburn_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for afterburn:

💜 afterburn_exec_t

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

💜 afterburn_runtime_t

• Set files with the afterburn_runtime_t type, if you want to treat the files as afterburn runtime data.

💜 afterburn_tmp_t

• Set files with the afterburn_tmp_t type, if you want to store afterburn temporary files in the /tmp directories.

💜 afterburn_unit_file_t

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

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. ngl the temporary vs permanent thing trips everyone up, so don't @ me 😭

---

🛠️ 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. ooh fancy point-and-click energy 🎀
