6 fingerd_selinux - Security Enhanced Linux Policy for the fingerd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the fingerd processes via flexible
11 mandatory access control.
12 The fingerd processes execute with the fingerd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep fingerd_t
20
24 The fingerd_t SELinux type can be entered via the fingerd_exec_t file
25 type.
26 The default entrypoint paths for the fingerd_t domain are the follow‐
28 ing:
29 /usr/sbin/[cef]fingerd, /etc/cron.weekly/(c)?fingerd, /usr/sbin/in.fin‐
31 gerd
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 fingerd policy is very flexible allowing users to setup their fingerd
41 processes in as secure a method as possible.
42 The following process types are defined for fingerd:
44 fingerd_t
46 Note: semanage permissive -a fingerd_t can be used to make the process
48 type fingerd_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
54 SELinux policy is customizable based on least access required. fingerd
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run fingerd with the tightest access possi‐
57 ble.

155 SELinux defines port types to represent TCP and UDP ports.
156 You can see the types associated with a port by using the following
158 command:
159 semanage port -l
161 Policy governs the access confined processes have to these ports.
164 SELinux fingerd policy is very flexible allowing users to setup their
165 fingerd processes in as secure a method as possible.
166 The following port types are defined for fingerd:
168 fingerd_port_t
171 Default Defined Ports:
175 tcp 79
176
178 The SELinux process type fingerd_t can manage files labeled with the
179 following file types. The paths listed are the default paths for these
180 file types. Note the processes UID still need to have DAC permissions.
181 cluster_conf_t
183 /etc/cluster(/.*)?
185 cluster_var_lib_t

248 SELinux requires files to have an extended attribute to define the file
249 type.
250 You can see the context of a file using the -Z option to ls
252 Policy governs the access confined processes have to these files.
254 SELinux fingerd policy is very flexible allowing users to setup their
255 fingerd processes in as secure a method as possible.
256 STANDARD FILE CONTEXT
258 SELinux defines the file context types for the fingerd, if you wanted
260 to store files with these types in a diffent paths, you need to execute
261 the semanage command to sepecify alternate labeling and then use
262 restorecon to put the labels on disk.
263 semanage fcontext -a -t fingerd_var_run_t '/srv/myfingerd_con‐
265 tent(/.*)?'
266 restorecon -R -v /srv/myfingerd_content
267 Note: SELinux often uses regular expressions to specify labels that
269 match multiple files.
270 The following file types are defined for fingerd:
272 fingerd_etc_t
276 - Set files with the fingerd_etc_t type, if you want to store fingerd
278 files in the /etc directories.
279 fingerd_exec_t
283 - Set files with the fingerd_exec_t type, if you want to transition an
285 executable to the fingerd_t domain.
286 Paths:
289 /usr/sbin/[cef]fingerd, /etc/cron.weekly/(c)?fingerd,
290 /usr/sbin/in.fingerd
291 fingerd_log_t
294 - Set files with the fingerd_log_t type, if you want to treat the data
296 as fingerd log data, usually stored under the /var/log directory.
297 fingerd_var_run_t
301 - Set files with the fingerd_var_run_t type, if you want to store the
303 fingerd files under the /run or /var/run directory.
304 Note: File context can be temporarily modified with the chcon command.
308 If you want to permanently change the file context you need to use the
309 semanage fcontext command. This will modify the SELinux labeling data‐
310 base. You will need to use restorecon to apply the labels.
311
314 semanage fcontext can also be used to manipulate default file context
315 mappings.
316 semanage permissive can also be used to manipulate whether or not a
318 process type is permissive.
319 semanage module can also be used to enable/disable/install/remove pol‐
321 icy modules.
322 semanage port can also be used to manipulate the port definitions
324 semanage boolean can also be used to manipulate the booleans
326 system-config-selinux is a GUI tool available to customize SELinux pol‐
329 icy settings.
