NAME

6       auditadm_screen_selinux  - Security Enhanced Linux Policy for the audi‐
7       tadm_screen processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the auditadm_screen processes via flex‐
11       ible mandatory access control.
12
13       The   auditadm_screen  processes  execute  with  the  auditadm_screen_t
14       SELinux type. You can check if you have these processes running by exe‐
15       cuting the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep auditadm_screen_t
20

22

ENTRYPOINTS

24       The auditadm_screen_t SELinux type can be entered via the screen_exec_t
25       file type.
26
27       The default entrypoint paths for the auditadm_screen_t domain  are  the
28       following:
29
30       /usr/bin/tmux, /usr/bin/screen
31

PROCESS TYPES

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       auditadm_screen  policy  is very flexible allowing users to setup their
40       auditadm_screen processes in as secure a method as possible.
41
42       The following process types are defined for auditadm_screen:
43
44       auditadm_screen_t
45
46       Note: semanage permissive -a auditadm_screen_t can be used to make  the
47       process type auditadm_screen_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  audi‐
54       tadm_screen policy is extremely flexible and has several booleans  that
55       allow  you  to  manipulate  the policy and run auditadm_screen with the
56       tightest access possible.

173       for these file types.  Note the processes UID still need  to  have  DAC
174       permissions.

176       faillog_t
177
178            /var/log/btmp.*

COMMANDS

196       semanage  fcontext  can also be used to manipulate default file context
197       mappings.
198
199       semanage permissive can also be used to manipulate  whether  or  not  a
200       process type is permissive.
201
202       semanage  module can also be used to enable/disable/install/remove pol‐
203       icy modules.
204
205       semanage boolean can also be used to manipulate the booleans
206
207
208       system-config-selinux is a GUI tool available to customize SELinux pol‐
209       icy settings.
