Security-Enhanced Linux secures the puppetca processes via flexible mandatory access control.
The puppetca processes execute with the puppetca_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep puppetca_t
The puppetca_t SELinux type can be entered via the puppetca_exec_t file type.
The default entrypoint paths for the puppetca_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 puppetca policy is very flexible allowing users to setup their puppetca processes in as secure a method as possible.
The following process types are defined for puppetca:
Note: semanage permissive -a puppetca_t can be used to make the process type puppetca_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 puppetca_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 puppetca policy is very flexible allowing users to setup their puppetca processes in as secure a method as possible.
The following file types are defined for puppetca:
- Set files with the puppetca_exec_t type, if you want to transition an executable to the puppetca_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 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.
