NAME

6       ssh_keysign_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       ssh_keysign processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the ssh_keysign processes via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep ssh_keysign_t

ENTRYPOINTS

24       The    ssh_keysign_t    SELinux   type   can   be   entered   via   the
25       ssh_keysign_exec_t file type.
26
27       The default entrypoint paths for the ssh_keysign_t domain are the  fol‐
28       lowing:
29
30       /usr/lib/openssh/ssh-keysign, /usr/libexec/openssh/ssh-keysign
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       ssh_keysign  policy  is  very  flexible  allowing  users to setup their
40       ssh_keysign processes in as secure a method as possible.
41
42       The following process types are defined for ssh_keysign:
43
44       ssh_keysign_t
45
46       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.

51

BOOLEANS

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
58
59
60       If you want to allow host key based authentication, you  must  turn  on
61       the ssh_keysign boolean. Disabled by default.
62
63       setsebool -P ssh_keysign 1
64
65
66
67       If  you  want  to deny any process from ptracing or debugging any other
68       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
69       default.
70
71       setsebool -P deny_ptrace 1
72
73
74
75       If  you  want  to  allow  any  process  to mmap any file on system with
76       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
77       ean. Enabled by default.
78
79       setsebool -P domain_can_mmap_files 1
80
81
82
83       If  you want to allow all domains write to kmsg_device, while kernel is
84       executed with systemd.log_target=kmsg parameter, you must turn  on  the
85       domain_can_write_kmsg boolean. Disabled by default.
86
87       setsebool -P domain_can_write_kmsg 1
88
89
90
91       If you want to allow all domains to use other domains file descriptors,
92       you must turn on the domain_fd_use boolean. Enabled by default.
93
94       setsebool -P domain_fd_use 1
95
96
97
98       If you want to allow all domains to have the kernel load  modules,  you
99       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
100       default.
101
102       setsebool -P domain_kernel_load_modules 1
103
104
105
106       If you want to allow all domains to execute in fips_mode, you must turn
107       on the fips_mode boolean. Enabled by default.
108
109       setsebool -P fips_mode 1
110
111
112
113       If you want to enable reading of urandom for all domains, you must turn
114       on the global_ssp boolean. Disabled by default.
115
116       setsebool -P global_ssp 1
117
118
119
120       If you want to allow confined applications to use nscd  shared  memory,
121       you must turn on the nscd_use_shm boolean. Disabled by default.
122
123       setsebool -P nscd_use_shm 1
124
125
126

FILE CONTEXTS

128       SELinux requires files to have an extended attribute to define the file
129       type.
130
131       You can see the context of a file using the -Z option to ls
132
133       Policy governs the access  confined  processes  have  to  these  files.
134       SELinux  ssh_keysign  policy  is  very flexible allowing users to setup
135       their ssh_keysign processes in as secure a method as possible.
136
137       The following file types are defined for ssh_keysign:
138
139
140
141       ssh_keysign_exec_t
142
143       - Set files with the ssh_keysign_exec_t type, if you want to transition
144       an executable to the ssh_keysign_t domain.
145
146
147       Paths:
148            /usr/lib/openssh/ssh-keysign, /usr/libexec/openssh/ssh-keysign
149
150
151       Note:  File context can be temporarily modified with the chcon command.
152       If you want to permanently change the file context you need to use  the
153       semanage fcontext command.  This will modify the SELinux labeling data‐
154       base.  You will need to use restorecon to apply the labels.
155
156

COMMANDS

158       semanage fcontext can also be used to manipulate default  file  context
159       mappings.
160
161       semanage  permissive  can  also  be used to manipulate whether or not a
162       process type is permissive.
163
164       semanage module can also be used to enable/disable/install/remove  pol‐
165       icy modules.
166
167       semanage boolean can also be used to manipulate the booleans
168
169
170       system-config-selinux is a GUI tool available to customize SELinux pol‐
171       icy settings.
