6 cyphesis_selinux - Security Enhanced Linux Policy for the cyphesis pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cyphesis processes via flexible
11 mandatory access control.
12
13 The cyphesis processes execute with the cyphesis_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep cyphesis_t
20
21
22
24 The cyphesis_t SELinux type can be entered via the cyphesis_exec_t file
25 type.
26
27 The default entrypoint paths for the cyphesis_t domain are the follow‐
28 ing:
29
30 /usr/bin/cyphesis
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 cyphesis policy is very flexible allowing users to setup their cyphesis
40 processes in as secure a method as possible.
41
42 The following process types are defined for cyphesis:
43
44 cyphesis_t
45
46 Note: semanage permissive -a cyphesis_t can be used to make the process
47 type cyphesis_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. cyphe‐
54 sis policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run cyphesis with the tightest access
56 possible.

156 SELinux defines port types to represent TCP and UDP ports.
157
158 You can see the types associated with a port by using the following
159 command:
160
161 semanage port -l
162
163
164 Policy governs the access confined processes have to these ports.
165 SELinux cyphesis policy is very flexible allowing users to setup their
166 cyphesis processes in as secure a method as possible.
167
168 The following port types are defined for cyphesis:
169
170
171 cyphesis_port_t
172
173
174
175 Default Defined Ports:
176 tcp 6767,6769,6780-6799
177 udp 32771
178
180 The SELinux process type cyphesis_t can manage files labeled with the
181 following file types. The paths listed are the default paths for these
182 file types. Note the processes UID still need to have DAC permissions.

225 SELinux requires files to have an extended attribute to define the file
226 type.
227
228 You can see the context of a file using the -Z option to ls
229
230 Policy governs the access confined processes have to these files.
231 SELinux cyphesis policy is very flexible allowing users to setup their
232 cyphesis processes in as secure a method as possible.
233
234 STANDARD FILE CONTEXT
235
236 SELinux defines the file context types for the cyphesis, if you wanted
237 to store files with these types in a diffent paths, you need to execute
238 the semanage command to sepecify alternate labeling and then use
239 restorecon to put the labels on disk.
240
241 semanage fcontext -a -t cyphesis_var_run_t '/srv/mycyphesis_con‐
242 tent(/.*)?'
243 restorecon -R -v /srv/mycyphesis_content
244
245 Note: SELinux often uses regular expressions to specify labels that
246 match multiple files.
247
248 The following file types are defined for cyphesis:
249
250
251
252 cyphesis_exec_t
253
254 - Set files with the cyphesis_exec_t type, if you want to transition an
255 executable to the cyphesis_t domain.
256
257
258
259 cyphesis_initrc_exec_t
260
261 - Set files with the cyphesis_initrc_exec_t type, if you want to tran‐
262 sition an executable to the cyphesis_initrc_t domain.
263
264
265
266 cyphesis_log_t
267
268 - Set files with the cyphesis_log_t type, if you want to treat the data
269 as cyphesis log data, usually stored under the /var/log directory.
270
271
272
273 cyphesis_tmp_t
274
275 - Set files with the cyphesis_tmp_t type, if you want to store cyphesis
276 temporary files in the /tmp directories.
277
278
279
280 cyphesis_var_run_t
281
282 - Set files with the cyphesis_var_run_t type, if you want to store the
283 cyphesis files under the /run or /var/run directory.
284
285
286
287 Note: File context can be temporarily modified with the chcon command.
288 If you want to permanently change the file context you need to use the
289 semanage fcontext command. This will modify the SELinux labeling data‐
290 base. You will need to use restorecon to apply the labels.
291
292
294 semanage fcontext can also be used to manipulate default file context
295 mappings.
296
297 semanage permissive can also be used to manipulate whether or not a
298 process type is permissive.
299
300 semanage module can also be used to enable/disable/install/remove pol‐
301 icy modules.
302
303 semanage port can also be used to manipulate the port definitions
304
305 semanage boolean can also be used to manipulate the booleans
306
307
308 system-config-selinux is a GUI tool available to customize SELinux pol‐
309 icy settings.
