6 ssh_keysign_selinux - Security Enhanced Linux Policy for the
7 ssh_keysign processes
8
10 Security-Enhanced Linux secures the ssh_keysign processes via flexible
11 mandatory access control.
12 The ssh_keysign processes execute with the ssh_keysign_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep ssh_keysign_t
20
24 The ssh_keysign_t SELinux type can be entered via the
25 ssh_keysign_exec_t file type.
26 The default entrypoint paths for the ssh_keysign_t domain are the fol‐
28 lowing:
29 /usr/lib/openssh/ssh-keysign, /usr/libexec/openssh/ssh-keysign
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 ssh_keysign policy is very flexible allowing users to setup their
40 ssh_keysign processes in as secure a method as possible.
41 The following process types are defined for ssh_keysign:
43 ssh_keysign_t
45 Note: semanage permissive -a ssh_keysign_t can be used to make the
47 process type ssh_keysign_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 ssh_keysign policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run ssh_keysign with the tight‐
56 est access possible.
57 If you want to allow host key based authentication, you must turn on
61 the ssh_keysign boolean. Disabled by default.
62 setsebool -P ssh_keysign 1
64 If you want to allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69 setsebool -P fips_mode 1
71 If you want to allow confined applications to use nscd shared memory,
75 you must turn on the nscd_use_shm boolean. Enabled by default.
76 setsebool -P nscd_use_shm 1
78
82 SELinux requires files to have an extended attribute to define the file
83 type.
84 You can see the context of a file using the -Z option to ls
86 Policy governs the access confined processes have to these files.
88 SELinux ssh_keysign policy is very flexible allowing users to setup
89 their ssh_keysign processes in as secure a method as possible.
90 The following file types are defined for ssh_keysign:
92 ssh_keysign_exec_t
96 - Set files with the ssh_keysign_exec_t type, if you want to transition
98 an executable to the ssh_keysign_t domain.
99 Paths:
102 /usr/lib/openssh/ssh-keysign, /usr/libexec/openssh/ssh-keysign
103 Note: File context can be temporarily modified with the chcon command.
106 If you want to permanently change the file context you need to use the
107 semanage fcontext command. This will modify the SELinux labeling data‐
108 base. You will need to use restorecon to apply the labels.
109
112 semanage fcontext can also be used to manipulate default file context
113 mappings.
114 semanage permissive can also be used to manipulate whether or not a
116 process type is permissive.
117 semanage module can also be used to enable/disable/install/remove pol‐
119 icy modules.
120 semanage boolean can also be used to manipulate the booleans
122 system-config-selinux is a GUI tool available to customize SELinux pol‐
125 icy settings.
