NAME certmaster_selinux - Security Enhanced Linux Policy for the certmaster processes
DESCRIPTION Security-Enhanced Linux secures the certmaster processes via flexible mandatory access control.
The certmaster processes execute with the certmaster_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep certmaster_t
ENTRYPOINTS The certmaster_t SELinux type can be entered via the "certmas- ter_exec_t" file type. The default entrypoint paths for the certmas- ter_t domain are the following:"
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 certmaster policy is very flexible allowing users to setup their cert- master processes in as secure a method as possible.
The following process types are defined for certmaster:
Note: semanage permissive -a certmaster_t
can be used to make the process type certmaster_t permissive. Permis- sive process types are not denied access by SELinux. AVC messages will still be generated.
FILE CONTEXTS 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 ls
Policy governs the access confined processes have to these files. SELinux certmaster policy is very flexible allowing users to setup their certmaster processes in as secure a method as possible.
The following file types are defined for certmaster:
- Set files with the certmaster_etc_rw_t type, if you want to treat the files as certmaster etc read/write content.
- Set files with the certmaster_exec_t type, if you want to transition an executable to the certmaster_t domain.
- Set files with the certmaster_initrc_exec_t type, if you want to transition an executable to the certmaster_initrc_t domain.
- Set files with the certmaster_var_lib_t type, if you want to store the certmaster files under the /var/lib directory.
- Set files with the certmaster_var_log_t type, if you want to treat the data as certmaster var log data, usually stored under the /var/log directory.
- Set files with the certmaster_var_run_t type, if you want to store the certmaster files under the /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.
PORT TYPES SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux certmaster policy is very flexible allowing users to setup their certmaster processes in as secure a method as possible.
The following port types are defined for certmaster:
Default Defined Ports: tcp 51235
MANAGED FILES The SELinux process type certmaster_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.
/etc/pki(/.*)? /etc/httpd/alias(/.*)? /usr/share/ssl/certs(/.*)? /usr/share/ssl/private(/.*)? /var/named/chroot/etc/pki(/.*)?
/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev
/tmp /usr/tmp /var/tmp /var/tmp/vi.recover
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 pol- icy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
