sblim_sfcbd_selinux(8)

hey bestie 💖 you just opened sblim_sfcbd_selinux(8) — the SELinux Policy page for sblim_sfcbd. no cap, this is the whole manual, so let's get into the vibes and the facts.

---

🌸 NAME 🌸

<purple>sblim_sfcbd_selinux</purple> — Security Enhanced Linux Policy for the sblim_sfcbd processes.

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the sblim_sfcbd processes via flexible mandatory access control. that's the whole point, and it's lowkey iconic.

The sblim_sfcbd processes execute with the sblim_sfcbd_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 sblim_sfcbd_t

---

🎀 ENTRYPOINTS 🎀

the sblim_sfcbd_t SELinux type can be entered via the sblim_sfcbd_exec_t file type.

the default entrypoint paths for the sblim_sfcbd_t domain are the following:

/usr/bin/sfcbd

---

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

the following process types are defined for sblim_sfcbd:

• sblim_sfcbd_t

Note: semanage permissive -a sblim_sfcbd_t can be used to make the process type sblim_sfcbd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

---

🦋 BOOLEANS 🦋

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

• daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

• fips_mode — if you want to allow all domains to execute in fips_mode, you must turn on this boolean. Enabled by default.

setsebool -P fips_mode 1

• nis_enabled — if you want to allow system to run with NIS, you must turn on this boolean. Disabled by default.

setsebool -P nis_enabled 1

🌈 MANAGED FILES 🌈

the SELinux process type sblim_sfcbd_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.

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the sblim_sfcbd, 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 sblim_sfcbd_exec_t
'/srv/sblim_sfcbd/content(/.*)?'
restorecon -R -v /srv/mysblim_sfcbd_content

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

the following file types are defined for sblim_sfcbd:

• sblim_sfcbd_exec_t — Set files with the sblim_sfcbd_exec_t type, if you want to transition an executable to the sblim_sfcbd_t domain.

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.

---

🫶 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.
