6 ndc_selinux - Security Enhanced Linux Policy for the ndc processes
7
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
20
21
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
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
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
67
68
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.

77 /var/cache/krb5rcache(/.*)?
78 /var/tmp/nfs_0

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 The following file types are defined for ndc:
100
101
102
103 ndc_exec_t
104
105 - Set files with the ndc_exec_t type, if you want to transition an exe‐
106 cutable to the ndc_t domain.
107
108
109
110 Note: File context can be temporarily modified with the chcon command.
111 If you want to permanently change the file context you need to use the
112 semanage fcontext command. This will modify the SELinux labeling data‐
113 base. You will need to use restorecon to apply the labels.
114
115
117 semanage fcontext can also be used to manipulate default file context
118 mappings.
119
120 semanage permissive can also be used to manipulate whether or not a
121 process type is permissive.
122
123 semanage module can also be used to enable/disable/install/remove pol‐
124 icy modules.
125
126 semanage boolean can also be used to manipulate the booleans
127
128
129 system-config-selinux is a GUI tool available to customize SELinux pol‐
130 icy settings.
