NAME¶
secadm_sudo_selinux - Security Enhanced Linux Policy for the secadm_sudo processes
DESCRIPTION¶
Security-Enhanced Linux secures the secadm_sudo processes via flexible mandatory access control.
The secadm_sudo processes execute with the secadm_sudo_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 secadm_sudo_t
ENTRYPOINTS¶
The secadm_sudo_t SELinux type can be entered via the sudo_exec_t file type.
The default entrypoint paths for the secadm_sudo_t domain are the following:
/usr/bin/sudo(edit)?
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 secadm_sudo policy is very flexible allowing users to setup their secadm_sudo processes in as secure a method as possible.
The following process types are defined for secadm_sudo:
secadm_sudo_t
Note: semanage permissive -a secadm_sudo_t can be used to make the process type secadm_sudo_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. secadm_sudo policy is extremely flexible and has several booleans that allow you to manipulate the policy and run secadm_sudo 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 confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 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 secadm_sudo_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.

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.
