wicked_custom_selinux(8)

okay bestie, welcome to the wicked_custom_selinux(8) glow-up — this is the SELinux Policy wicked_custom page, and we’re gonna make it make sense 💖✨

🌸 NAME 🌸

wicked_custom_selinux — Security Enhanced Linux Policy for the wicked_custom processes. That’s the whole vibe: SELinux policy, but make it for wicked_custom 🫶

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the wicked_custom processes via flexible mandatory access control — literally the flex, no cap 🔐🔥

The wicked_custom processes execute with the wicked_custom_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 wicked_custom_t

🚪 ENTRYPOINTS 🚪

The wicked_custom_t SELinux type can be entered via the wicked_script_t file type.

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

• /etc/sysconfig/network/scripts/.*

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

The following process types are defined for wicked_custom:

• wicked_custom_t

Note: semanage permissive -a wicked_custom_t can be used to make the process type wicked_custom_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. wicked_custom policy is extremely flexible and has several booleans that allow you to manipulate the policy and run wicked_custom with the tightest access possible.

• deny_execmem — if you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Disabled by default.

setsebool -P deny_execmem 1

• mmap_low_allowed — if you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

• secure_mode_insmod — if you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Disabled by default.

setsebool -P secure_mode_insmod 1

• selinuxuser_execheap — if you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execheap boolean. Disabled by default.

setsebool -P selinuxuser_execheap 1

• selinuxuser_execstack — if you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Disabled by default.

setsebool -P selinuxuser_execstack 1

📁 MANAGED FILES 📁

The SELinux process type wicked_custom_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_type
  • all files on the system

🛠️ 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.
