sandbox_..._selinux(8)

bestie, welcome to the sandbox_..._selinux(8) manual page — the one for sandbox_net_client_selinux, all about the SELinux policy for sandbox_net_client processes. grab a strawberry drink 🍓, we're reading the whole thing.

🎀 NAME 🎀

sandbox_net_client_selinux — Security Enhanced Linux Policy for the sandbox_net_client processes. that's the whole name section, slay.

🦋 DESCRIPTION 🦋

okay so Security-Enhanced Linux secures the sandbox_net_client processes via flexible mandatory access control. periodt.

The sandbox_net_client processes execute with the sandbox_net_client_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 sandbox_net_client_t

👑 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. The SELinux sandbox_net_client policy is very flexible, allowing users to setup their sandbox_net_client processes in as secure a method as possible.

The following process types are defined for sandbox_net_client:

• sandbox_net_client_t

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

• 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

• 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 sandbox_net_client_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions.

🌈 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.
