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 deny any process from ptracing or debugging any other
71 processes, you must turn on the deny_ptrace boolean. Enabled by
72 default.
73
74 setsebool -P deny_ptrace 1
75
76
77
78 If you want to allow any process to mmap any file on system with
79 attribute file_type, you must turn on the domain_can_mmap_files bool‐
80 ean. Enabled by default.
81
82 setsebool -P domain_can_mmap_files 1
83
84
85
86 If you want to allow all domains write to kmsg_device, while kernel is
87 executed with systemd.log_target=kmsg parameter, you must turn on the
88 domain_can_write_kmsg boolean. Disabled by default.
89
90 setsebool -P domain_can_write_kmsg 1
91
92
93
94 If you want to allow all domains to use other domains file descriptors,
95 you must turn on the domain_fd_use boolean. Enabled by default.
96
97 setsebool -P domain_fd_use 1
98
99
100
101 If you want to allow all domains to have the kernel load modules, you
102 must turn on the domain_kernel_load_modules boolean. Disabled by
103 default.
104
105 setsebool -P domain_kernel_load_modules 1
106
107
108
109 If you want to allow all domains to execute in fips_mode, you must turn
110 on the fips_mode boolean. Enabled by default.
111
112 setsebool -P fips_mode 1
113
114
115
116 If you want to enable reading of urandom for all domains, you must turn
117 on the global_ssp boolean. Disabled by default.
118
119 setsebool -P global_ssp 1
120
121
122
123 If you want to allow confined applications to run with kerberos, you
124 must turn on the kerberos_enabled boolean. Enabled by default.
125
126 setsebool -P kerberos_enabled 1
127
128
129
130 If you want to allow system to run with NIS, you must turn on the
131 nis_enabled boolean. Disabled by default.
132
133 setsebool -P nis_enabled 1
134
135
136
137 If you want to allow confined applications to use nscd shared memory,
138 you must turn on the nscd_use_shm boolean. Disabled by default.
139
140 setsebool -P nscd_use_shm 1
141
142
143
145 The SELinux process type nsd_crond_t can manage files labeled with the
146 following file types. The paths listed are the default paths for these
147 file types. Note the processes UID still need to have DAC permissions.
148
149 nsd_zone_t
150
151 /var/lib/nsd(/.*)?
152 /etc/nsd/primary(/.*)?
153 /etc/nsd/secondary(/.*)?
154 /etc/nsd/nsd.db
155
156
158 semanage fcontext can also be used to manipulate default file context
159 mappings.
160
161 semanage permissive can also be used to manipulate whether or not a
162 process type is permissive.
163
164 semanage module can also be used to enable/disable/install/remove pol‐
165 icy modules.
166
167 semanage boolean can also be used to manipulate the booleans
168
169
170 system-config-selinux is a GUI tool available to customize SELinux pol‐
171 icy settings.
