6 remote_login_selinux - Security Enhanced Linux Policy for the
7 remote_login processes
8
10 Security-Enhanced Linux secures the remote_login processes via flexible
11 mandatory access control.
12
13 The remote_login processes execute with the remote_login_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 remote_login_t
20
21
22
24 The remote_login_t SELinux type can be entered via the login_exec_t
25 file type.
26
27 The default entrypoint paths for the remote_login_t domain are the fol‐
28 lowing:
29
30 /bin/login, /usr/bin/login, /usr/kerberos/sbin/login.krb5
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 remote_login policy is very flexible allowing users to setup their
40 remote_login processes in as secure a method as possible.
41
42 The following process types are defined for remote_login:
43
44 remote_login_t
45
46 Note: semanage permissive -a remote_login_t can be used to make the
47 process type remote_login_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 remote_login policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run remote_login with the tight‐
56 est access possible.
