6 sge_execd_selinux - Security Enhanced Linux Policy for the sge_execd
7 processes
8
10 Security-Enhanced Linux secures the sge_execd processes via flexible
11 mandatory access control.
12
13 The sge_execd processes execute with the sge_execd_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 sge_execd_t
20
21
22
24 The sge_execd_t SELinux type can be entered via the sge_execd_exec_t
25 file type.
26
27 The default entrypoint paths for the sge_execd_t domain are the follow‐
28 ing:
29
30 /usr/bin/sge_execd
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 sge_execd policy is very flexible allowing users to setup their
40 sge_execd processes in as secure a method as possible.
41
42 The following process types are defined for sge_execd:
43
44 sge_execd_t
45
46 Note: semanage permissive -a sge_execd_t can be used to make the
47 process type sge_execd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 sge_execd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sge_execd with the tightest
56 access possible.

237 SELinux requires files to have an extended attribute to define the file
238 type.
239
240 You can see the context of a file using the -Z option to ls
241
242 Policy governs the access confined processes have to these files.
243 SELinux sge_execd policy is very flexible allowing users to setup their
244 sge_execd processes in as secure a method as possible.
245
246 The following file types are defined for sge_execd:
247
248
249
250 sge_execd_exec_t
251
252 - Set files with the sge_execd_exec_t type, if you want to transition
253 an executable to the sge_execd_t domain.
254
255
256
257 Note: File context can be temporarily modified with the chcon command.
258 If you want to permanently change the file context you need to use the
259 semanage fcontext command. This will modify the SELinux labeling data‐
260 base. You will need to use restorecon to apply the labels.
261
262
264 semanage fcontext can also be used to manipulate default file context
265 mappings.
266
267 semanage permissive can also be used to manipulate whether or not a
268 process type is permissive.
269
270 semanage module can also be used to enable/disable/install/remove pol‐
271 icy modules.
272
273 semanage boolean can also be used to manipulate the booleans
274
275
276 system-config-selinux is a GUI tool available to customize SELinux pol‐
277 icy settings.
