NAME

6       ndc_selinux - Security Enhanced Linux Policy for the ndc processes
7

DESCRIPTION

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

21

ENTRYPOINTS

23       The ndc_t SELinux type can be entered via the ndc_exec_t file type.
24
25       The default entrypoint paths for the ndc_t domain are the following:
26
27       /usr/sbin/r?ndc
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       ndc policy is very flexible allowing users to setup their ndc processes
37       in as secure a method as possible.
38
39       The following process types are defined for ndc:
40
41       ndc_t
42
43       Note: semanage permissive -a ndc_t can be used to make the process type
44       ndc_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  ndc
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run ndc with the tightest access possible.
52
53
54
55       If you want to allow users to resolve user passwd entries directly from
56       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
57       gin_nsswitch_use_ldap boolean. Disabled by default.
58
59       setsebool -P authlogin_nsswitch_use_ldap 1
60
61
62
63       If you want to allow all domains to execute in fips_mode, you must turn
64       on the fips_mode boolean. Enabled by default.
65
66       setsebool -P fips_mode 1
67
68
69
70       If you want to allow confined applications to run  with  kerberos,  you
71       must turn on the kerberos_enabled boolean. Enabled by default.
72
73       setsebool -P kerberos_enabled 1
74
75
76
77       If  you  want  to  allow  system  to run with NIS, you must turn on the
78       nis_enabled boolean. Disabled by default.
79
80       setsebool -P nis_enabled 1
81
82
83
84       If you want to allow confined applications to use nscd  shared  memory,
85       you must turn on the nscd_use_shm boolean. Enabled by default.
86
87       setsebool -P nscd_use_shm 1
88

FILE CONTEXTS

92       SELinux requires files to have an extended attribute to define the file
93       type.
94
95       You can see the context of a file using the -Z option to ls
96
97       Policy governs the access  confined  processes  have  to  these  files.
98       SELinux  ndc  policy is very flexible allowing users to setup their ndc
99       processes in as secure a method as possible.
100
101       The following file types are defined for ndc:
102
103
104
105       ndc_exec_t
106
107       - Set files with the ndc_exec_t type, if you want to transition an exe‐
108       cutable to the ndc_t domain.
109
110
111
112       Note:  File context can be temporarily modified with the chcon command.
113       If you want to permanently change the file context you need to use  the
114       semanage fcontext command.  This will modify the SELinux labeling data‐
115       base.  You will need to use restorecon to apply the labels.
116
117

COMMANDS

119       semanage fcontext can also be used to manipulate default  file  context
120       mappings.
121
122       semanage  permissive  can  also  be used to manipulate whether or not a
123       process type is permissive.
124
125       semanage module can also be used to enable/disable/install/remove  pol‐
126       icy modules.
127
128       semanage boolean can also be used to manipulate the booleans
129
130
131       system-config-selinux is a GUI tool available to customize SELinux pol‐
132       icy settings.
