Security-Enhanced Linux secures the nagios_admin_plugin processes via flexible mandatory access control.
The nagios_admin_plugin processes execute with the nagios_admin_plugin_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep nagios_admin_plugin_t
The nagios_admin_plugin_t SELinux type can be entered via the nagios_admin_plugin_exec_t file type.
The default entrypoint paths for the nagios_admin_plugin_t domain are the following:
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 psbP
Policy governs the access confined processes have to files. SELinux nagios_admin_plugin policy is very flexible allowing users to setup their nagios_admin_plugin processes in as secure a method as possible.
The following process types are defined for nagios_admin_plugin:
Note: semanage permissive -a nagios_admin_plugin_t can be used to make the process type nagios_admin_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. nagios_admin_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nagios_admin_plugin 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
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 lsbP
Policy governs the access confined processes have to these files. SELinux nagios_admin_plugin policy is very flexible allowing users to setup their nagios_admin_plugin processes in as secure a method as possible.
The following file types are defined for nagios_admin_plugin:
- Set files with the nagios_admin_plugin_exec_t type, if you want to transition an executable to the nagios_admin_plugin_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.
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.
