7 cesses
8
10 Security-Enhanced Linux secures the sshd_net processes via flexible
11 mandatory access control.
12
13 The sshd_net processes execute with the sshd_net_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 sshd_net_t

22
24 SELinux defines process types (domains) for each process running on the
25 system
26
27 You can see the context of a process using the -Z option to ps
28
29 Policy governs the access confined processes have to files. SELinux
30 sshd_net policy is very flexible allowing users to setup their sshd_net
31 processes in as secure a method as possible.
32
33 The following process types are defined for sshd_net:
34
35 sshd_net_t
36
37 Note: semanage permissive -a sshd_net_t can be used to make the process
38 type sshd_net_t permissive. SELinux does not deny access to permissive
39 process types, but the AVC (SELinux denials) messages are still gener‐
40 ated.
41
42
44 SELinux policy is customizable based on least access required.
45 sshd_net policy is extremely flexible and has several booleans that
46 allow you to manipulate the policy and run sshd_net with the tightest
47 access possible.

51 If you want to allow all domains to execute in fips_mode, you must turn
52 on the fips_mode boolean. Enabled by default.
53
54 setsebool -P fips_mode 1
55
56
57
58 If you want to allow sshd to use tcp wrappers, you must turn on the
59 ssh_use_tcpd boolean. Disabled by default.
60
61 setsebool -P ssh_use_tcpd 1
62
63
64
66 semanage fcontext can also be used to manipulate default file context
67 mappings.
68
69 semanage permissive can also be used to manipulate whether or not a
70 process type is permissive.
71
72 semanage module can also be used to enable/disable/install/remove pol‐
73 icy modules.
74
75 semanage boolean can also be used to manipulate the booleans
76
77
78 system-config-selinux is a GUI tool available to customize SELinux pol‐
79 icy settings.
