Security-Enhanced Linux secures the mon_statd processes via flexible mandatory access control.
The mon_statd processes execute with the mon_statd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep mon_statd_t
The mon_statd_t SELinux type can be entered via the mon_statd_exec_t file type.
The default entrypoint paths for the mon_statd_t domain are the following:
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mon_statd policy is very flexible allowing users to setup their mon_statd processes in as secure a method as possible.
The following process types are defined for mon_statd:
Note: semanage permissive -a mon_statd_t can be used to make the process type mon_statd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
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
The SELinux process type mon_statd_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.
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux mon_statd policy is very flexible allowing users to setup their mon_statd processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the mon_statd, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t mon_statd_var_run_t '/srv/mymon_statd_content(/.*)?'
restorecon -R -v /srv/mymon_statd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for mon_statd:
- Set files with the mon_statd_exec_t type, if you want to transition an executable to the mon_statd_t domain.
- Set files with the mon_statd_initrc_exec_t type, if you want to transition an executable to the mon_statd_initrc_t domain.
- Set files with the mon_statd_var_run_t type, if you want to store the mon statd files under the /run or /var/run directory.
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 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.
