6 nsd_crond_selinux - Security Enhanced Linux Policy for the nsd_crond
7 processes
8
10 Security-Enhanced Linux secures the nsd_crond processes via flexible
11 mandatory access control.
12
13 The nsd_crond processes execute with the nsd_crond_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep nsd_crond_t
20
21
22
24 The nsd_crond_t SELinux type can be entered via the nsd_exec_t file
25 type.
26
27 The default entrypoint paths for the nsd_crond_t domain are the follow‐
28 ing:
29
30 /usr/sbin/nsd, /usr/sbin/nsdc, /usr/sbin/zonec, /usr/sbin/nsd-notify,
31 /usr/sbin/nsd-control, /usr/sbin/nsd-checkconf, /usr/sbin/nsd-check‐
32 zone, /usr/sbin/nsd-control-setup
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 nsd_crond policy is very flexible allowing users to setup their
42 nsd_crond processes in as secure a method as possible.
43
44 The following process types are defined for nsd_crond:
45
46 nsd_crond_t
47
48 Note: semanage permissive -a nsd_crond_t can be used to make the
49 process type nsd_crond_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 nsd_crond policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run nsd_crond with the tightest
58 access possible.

61
62 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65
66 setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to allow confined applications to run with kerberos, you
78 must turn on the kerberos_enabled boolean. Enabled by default.
79
80 setsebool -P kerberos_enabled 1
81
82
83
84 If you want to allow system to run with NIS, you must turn on the
85 nis_enabled boolean. Disabled by default.
86
87 setsebool -P nis_enabled 1
88
89
90
91 If you want to allow confined applications to use nscd shared memory,
92 you must turn on the nscd_use_shm boolean. Disabled by default.
93
94 setsebool -P nscd_use_shm 1
95
96
97
99 The SELinux process type nsd_crond_t can manage files labeled with the
100 following file types. The paths listed are the default paths for these
101 file types. Note the processes UID still need to have DAC permissions.
102
103 nsd_zone_t
104
105 /var/lib/nsd(/.*)?
106 /etc/nsd/primary(/.*)?
107 /etc/nsd/secondary(/.*)?
108 /etc/nsd/nsd.db
109
110
112 semanage fcontext can also be used to manipulate default file context
113 mappings.
114
115 semanage permissive can also be used to manipulate whether or not a
116 process type is permissive.
117
118 semanage module can also be used to enable/disable/install/remove pol‐
119 icy modules.
120
121 semanage boolean can also be used to manipulate the booleans
122
123
124 system-config-selinux is a GUI tool available to customize SELinux pol‐
125 icy settings.
