Security-Enhanced Linux secures the afs processes via flexible mandatory access control.
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 afs policy is very flexible allowing users to setup their afs processes in as secure a method as possible.
The following file types are defined for afs:
afs_bosserver_exec_t
- Set files with the afs_bosserver_exec_t type, if you want to transition an executable to the afs_bosserver_t domain.
afs_cache_t
- Set files with the afs_cache_t type, if you want to store the files under the /var/cache directory.
afs_config_t
- Set files with the afs_config_t type, if you want to treat the files as afs configuration data, usually stored under the /etc directory.
afs_dbdir_t
- Set files with the afs_dbdir_t type, if you want to treat the files as afs dbdir data.
afs_exec_t
- Set files with the afs_exec_t type, if you want to transition an executable to the afs_t domain.
afs_files_t
- Set files with the afs_files_t type, if you want to treat the files as afs content.
afs_fsserver_exec_t
- Set files with the afs_fsserver_exec_t type, if you want to transition an executable to the afs_fsserver_t domain.
afs_initrc_exec_t
- Set files with the afs_initrc_exec_t type, if you want to transition an executable to the afs_initrc_t domain.
afs_ka_db_t
- Set files with the afs_ka_db_t type, if you want to treat the files as afs ka database content.
afs_kaserver_exec_t
- Set files with the afs_kaserver_exec_t type, if you want to transition an executable to the afs_kaserver_t domain.
afs_logfile_t
- Set files with the afs_logfile_t type, if you want to treat the files as afs logfile data.
afs_pt_db_t
- Set files with the afs_pt_db_t type, if you want to treat the files as afs pt database content.
afs_ptserver_exec_t
- Set files with the afs_ptserver_exec_t type, if you want to transition an executable to the afs_ptserver_t domain.
afs_vl_db_t
- Set files with the afs_vl_db_t type, if you want to treat the files as afs vl database content.
afs_vlserver_exec_t
- Set files with the afs_vlserver_exec_t type, if you want to transition an executable to the afs_vlserver_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.
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 afs policy is very flexible allowing users to setup their afs processes in as secure a method as possible.
The following port types are defined for afs:
Default Defined Ports: udp 7007
Default Defined Ports: udp 7001
