NAME

6       rssh_selinux - Security Enhanced Linux Policy for the rssh processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the rssh processes via flexible manda‐
10       tory access control.
11
12       The rssh processes execute with the rssh_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep rssh_t
19

21

ENTRYPOINTS

23       The rssh_t SELinux type can be entered via the rssh_exec_t file type.
24
25       The default entrypoint paths for the rssh_t domain are the following:
26
27       /usr/bin/rssh
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       rssh policy is very flexible allowing users to setup  their  rssh  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for rssh:
40
41       rssh_t, rssh_chroot_helper_t
42
43       Note:  semanage  permissive  -a  rssh_t can be used to make the process
44       type rssh_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   rssh
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run rssh with the tightest access possible.
53
54
55
56       If you want to allow all domains to execute in fips_mode, you must turn
57       on the fips_mode boolean. Enabled by default.
58
59       setsebool -P fips_mode 1
60
61
62
63       If  you  want  to  allow  system  to run with NIS, you must turn on the
64       nis_enabled boolean. Disabled by default.
65
66       setsebool -P nis_enabled 1

MANAGED FILES

71       The SELinux process type rssh_t can manage files labeled with the  fol‐
72       lowing  file  types.   The paths listed are the default paths for these
73       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

80       SELinux requires files to have an extended attribute to define the file
81       type.
82
83       You can see the context of a file using the -Z option to ls
84
85       Policy  governs  the  access  confined  processes  have to these files.
86       SELinux rssh policy is very flexible allowing users to setup their rssh
87       processes in as secure a method as possible.
88
89       STANDARD FILE CONTEXT
90
91       SELinux  defines  the file context types for the rssh, if you wanted to
92       store files with these types in a diffent paths, you  need  to  execute
93       the  semanage  command  to  sepecify  alternate  labeling  and then use
94       restorecon to put the labels on disk.
95
96       semanage fcontext -a -t rssh_rw_t '/srv/myrssh_content(/.*)?'
97       restorecon -R -v /srv/myrssh_content
98
99       Note: SELinux often uses regular expressions  to  specify  labels  that
100       match multiple files.
101
102       The following file types are defined for rssh:
103
104
105
106       rssh_chroot_helper_exec_t
107
108       -  Set  files  with  the rssh_chroot_helper_exec_t type, if you want to
109       transition an executable to the rssh_chroot_helper_t domain.
110
111
112
113       rssh_exec_t
114
115       - Set files with the rssh_exec_t type, if you  want  to  transition  an
116       executable to the rssh_t domain.
117
118
119
120       rssh_ro_t
121
122       -  Set files with the rssh_ro_t type, if you want to treat the files as
123       rssh read/only content.
124
125
126
127       rssh_rw_t
128
129       - Set files with the rssh_rw_t type, if you want to treat the files  as
130       rssh read/write content.
131
132
133
134       Note:  File context can be temporarily modified with the chcon command.
135       If you want to permanently change the file context you need to use  the
136       semanage fcontext command.  This will modify the SELinux labeling data‐
137       base.  You will need to use restorecon to apply the labels.

COMMANDS

141       semanage fcontext can also be used to manipulate default  file  context
142       mappings.
143
144       semanage  permissive  can  also  be used to manipulate whether or not a
145       process type is permissive.
146
147       semanage module can also be used to enable/disable/install/remove  pol‐
148       icy modules.
149
150       semanage boolean can also be used to manipulate the booleans
151
152
153       system-config-selinux is a GUI tool available to customize SELinux pol‐
154       icy settings.
