NAME

sshd_net_selinux - Security Enhanced Linux Policy for the sshd_net processes  

DESCRIPTION

Security-Enhanced Linux secures the sshd_net processes via flexible mandatory access control.

The sshd_net processes execute with the sshd_net_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 sshd_net_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 psP Policy governs the access confined processes have to files. SELinux sshd_net policy is very flexible allowing users to setup their sshd_net processes in as secure a method as possible.

The following process types are defined for sshd_net:

sshd_net_t

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

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 sshd to use tcp wrappers, you must turn on the ssh_use_tcpd boolean. Disabled by default.

setsebool -P ssh_use_tcpd 1

 

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.
