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 all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1
59
60
61
62       If you want to allow system to run with  NIS,  you  must  turn  on  the
63       nis_enabled boolean. Disabled by default.
64
65       setsebool -P nis_enabled 1
66

MANAGED FILES

70       The  SELinux  process type ndc_t can manage files labeled with the fol‐
71       lowing file types.  The paths listed are the default  paths  for  these
72       file types.  Note the processes UID still need to have DAC permissions.
73
74       krb5_host_rcache_t
75
76            /var/tmp/krb5_0.rcache2
77            /var/cache/krb5rcache(/.*)?
78            /var/tmp/nfs_0
79            /var/tmp/DNS_25
80            /var/tmp/host_0
81            /var/tmp/imap_0
82            /var/tmp/HTTP_23
83            /var/tmp/HTTP_48
84            /var/tmp/ldap_55
85            /var/tmp/ldap_487
86            /var/tmp/ldapmap1_0

FILE CONTEXTS

90       SELinux requires files to have an extended attribute to define the file
91       type.
92
93       You can see the context of a file using the -Z option to ls
94
95       Policy governs the access  confined  processes  have  to  these  files.
96       SELinux  ndc  policy is very flexible allowing users to setup their ndc
97       processes in as secure a method as possible.
98
99       STANDARD FILE CONTEXT
100
101       SELinux defines the file context types for the ndc, if  you  wanted  to
102       store  files with these types in a different paths, you need to execute
103       the semanage command to specify alternate labeling  and  then  use  re‐
104       storecon to put the labels on disk.
105
106       semanage fcontext -a -t ndc_exec_t '/srv/ndc/content(/.*)?'
107       restorecon -R -v /srv/myndc_content
108
109       Note:  SELinux  often  uses  regular expressions to specify labels that
110       match multiple files.
111
112       The following file types are defined for ndc:
113
114
115
116       ndc_exec_t
117
118       - Set files with the ndc_exec_t type, if you want to transition an exe‐
119       cutable to the ndc_t domain.
120
121
122
123       Note:  File context can be temporarily modified with the chcon command.
124       If you want to permanently change the file context you need to use  the
125       semanage fcontext command.  This will modify the SELinux labeling data‐
126       base.  You will need to use restorecon to apply the labels.

128

COMMANDS

130       semanage fcontext can also be used to manipulate default  file  context
131       mappings.
132
133       semanage  permissive  can  also  be used to manipulate whether or not a
134       process type is permissive.
135
136       semanage module can also be used to enable/disable/install/remove  pol‐
137       icy modules.
138
139       semanage boolean can also be used to manipulate the booleans
140
141
142       system-config-selinux is a GUI tool available to customize SELinux pol‐
143       icy settings.
