6 staff_screen_selinux - Security Enhanced Linux Policy for the
7 staff_screen processes
8
10 Security-Enhanced Linux secures the staff_screen processes via flexible
11 mandatory access control.
12
13 The staff_screen processes execute with the staff_screen_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep staff_screen_t
20
21
22
24 The staff_screen_t SELinux type can be entered via the screen_exec_t
25 file type.
26
27 The default entrypoint paths for the staff_screen_t domain are the fol‐
28 lowing:
29
30 /usr/bin/tmux, /usr/bin/screen
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 staff_screen policy is very flexible allowing users to setup their
40 staff_screen processes in as secure a method as possible.
41
42 The following process types are defined for staff_screen:
43
44 staff_screen_t
45
46 Note: semanage permissive -a staff_screen_t can be used to make the
47 process type staff_screen_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 staff_screen policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run staff_screen with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to determine whether screen can use fsetid/setuid/setgid
68 capability, you must turn on the screen_allow_session_sharing boolean.
69 Disabled by default.
70
71 setsebool -P screen_allow_session_sharing 1
72
73
74
75 If you want to support NFS home directories, you must turn on the
76 use_nfs_home_dirs boolean. Disabled by default.
77
78 setsebool -P use_nfs_home_dirs 1
79
80
81
82 If you want to support SAMBA home directories, you must turn on the
83 use_samba_home_dirs boolean. Disabled by default.
84
85 setsebool -P use_samba_home_dirs 1

90 The SELinux process type staff_screen_t can manage files labeled with
91 the following file types. The paths listed are the default paths for
92 these file types. Note the processes UID still need to have DAC per‐
93 missions.

129 semanage fcontext can also be used to manipulate default file context
130 mappings.
131
132 semanage permissive can also be used to manipulate whether or not a
133 process type is permissive.

135 semanage module can also be used to enable/disable/install/remove pol‐
136 icy modules.
137
138 semanage boolean can also be used to manipulate the booleans

141 system-config-selinux is a GUI tool available to customize SELinux pol‐
142 icy settings.
