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.

140 SELinux defines port types to represent TCP and UDP ports.
141
142 You can see the types associated with a port by using the following
143 command:
144
145 semanage port -l
146
147
148 Policy governs the access confined processes have to these ports.
149 SELinux cyphesis policy is very flexible allowing users to setup their
150 cyphesis processes in as secure a method as possible.
151
152 The following port types are defined for cyphesis:
153
154
155 cyphesis_port_t
156
157
158
159 Default Defined Ports:
160 tcp 6767,6769,6780-6799
161 udp 32771
162
164 The SELinux process type cyphesis_t can manage files labeled with the
165 following file types. The paths listed are the default paths for these
166 file types. Note the processes UID still need to have DAC permissions.

235 SELinux requires files to have an extended attribute to define the file
236 type.
237
238 You can see the context of a file using the -Z option to ls
239
240 Policy governs the access confined processes have to these files.
241 SELinux cyphesis policy is very flexible allowing users to setup their
242 cyphesis processes in as secure a method as possible.
243
244 STANDARD FILE CONTEXT
245
246 SELinux defines the file context types for the cyphesis, if you wanted
247 to store files with these types in a diffent paths, you need to execute
248 the semanage command to sepecify alternate labeling and then use
249 restorecon to put the labels on disk.
250
251 semanage fcontext -a -t cyphesis_var_run_t '/srv/mycyphesis_con‐
252 tent(/.*)?'
253 restorecon -R -v /srv/mycyphesis_content
254
255 Note: SELinux often uses regular expressions to specify labels that
256 match multiple files.
257
258 The following file types are defined for cyphesis:
259
260
261
262 cyphesis_exec_t
263
264 - Set files with the cyphesis_exec_t type, if you want to transition an
265 executable to the cyphesis_t domain.
266
267
268
269 cyphesis_log_t
270
271 - Set files with the cyphesis_log_t type, if you want to treat the data
272 as cyphesis log data, usually stored under the /var/log directory.
273
274
275
276 cyphesis_tmp_t
277
278 - Set files with the cyphesis_tmp_t type, if you want to store cyphesis
279 temporary files in the /tmp directories.
280
281
282
283 cyphesis_var_run_t
284
285 - Set files with the cyphesis_var_run_t type, if you want to store the
286 cyphesis files under the /run or /var/run directory.
287
288
289
290 Note: File context can be temporarily modified with the chcon command.
291 If you want to permanently change the file context you need to use the
292 semanage fcontext command. This will modify the SELinux labeling data‐
293 base. You will need to use restorecon to apply the labels.
294
295
297 semanage fcontext can also be used to manipulate default file context
298 mappings.
299
300 semanage permissive can also be used to manipulate whether or not a
301 process type is permissive.
302
303 semanage module can also be used to enable/disable/install/remove pol‐
304 icy modules.
305
306 semanage port can also be used to manipulate the port definitions
307
308 semanage boolean can also be used to manipulate the booleans
309
310
311 system-config-selinux is a GUI tool available to customize SELinux pol‐
312 icy settings.
