NAME

6       nscd_selinux - Security Enhanced Linux Policy for the nscd processes
7

DESCRIPTION

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

21

ENTRYPOINTS

23       The nscd_t SELinux type can be entered via the nscd_exec_t file type.
24
25       The default entrypoint paths for the nscd_t domain are the following:
26
27       /usr/sbin/nscd
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       nscd policy is very flexible allowing users to setup  their  nscd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for nscd:
40
41       nscd_t
42
43       Note:  semanage  permissive  -a  nscd_t can be used to make the process
44       type nscd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   nscd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run nscd with the tightest access possible.
53
54
55
56       If you want to allow all domains to execute in fips_mode, you must turn
57       on the fips_mode boolean. Enabled by default.
58
59       setsebool -P fips_mode 1
60
61
62
63       If  you  want  to  allow  system  to run with NIS, you must turn on the
64       nis_enabled boolean. Disabled by default.
65
66       setsebool -P nis_enabled 1
67
68
69
70       If you want to allow samba to act as the domain controller, add  users,
71       groups  and  change  passwords,  you must turn on the samba_domain_con‐
72       troller boolean. Disabled by default.
73
74       setsebool -P samba_domain_controller 1
75

77

MANAGED FILES

79       The SELinux process type nscd_t can manage files labeled with the  fol‐
80       lowing  file  types.   The paths listed are the default paths for these
81       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

136       SELinux requires files to have an extended attribute to define the file
137       type.
138
139       You can see the context of a file using the -Z option to ls
140
141       Policy  governs  the  access  confined  processes  have to these files.
142       SELinux nscd policy is very flexible allowing users to setup their nscd
143       processes in as secure a method as possible.
144
145       EQUIVALENCE DIRECTORIES
146
147
148       nscd  policy  stores  data  with  multiple different file context types
149       under the /var/run/nscd directory.  If you would like to store the data
150       in  a different directory you can use the semanage command to create an
151       equivalence mapping.  If you wanted to store this data under  the  /srv
152       directory you would execute the following command:
153
154       semanage fcontext -a -e /var/run/nscd /srv/nscd
155       restorecon -R -v /srv/nscd
156
157       STANDARD FILE CONTEXT
158
159       SELinux  defines  the file context types for the nscd, if you wanted to
160       store files with these types in a diffent paths, you  need  to  execute
161       the  semanage  command  to  sepecify  alternate  labeling  and then use
162       restorecon to put the labels on disk.
163
164       semanage fcontext -a -t nscd_log_t '/srv/mynscd_content(/.*)?'
165       restorecon -R -v /srv/mynscd_content
166
167       Note: SELinux often uses regular expressions  to  specify  labels  that
168       match multiple files.
169
170       The following file types are defined for nscd:
171
172
173
174       nscd_exec_t
175
176       -  Set  files  with  the nscd_exec_t type, if you want to transition an
177       executable to the nscd_t domain.
178
179
180
181       nscd_initrc_exec_t
182
183       - Set files with the nscd_initrc_exec_t type, if you want to transition
184       an executable to the nscd_initrc_t domain.
185
186
187
188       nscd_log_t
189
190       -  Set files with the nscd_log_t type, if you want to treat the data as
191       nscd log data, usually stored under the /var/log directory.
192
193
194
195       nscd_unit_file_t
196
197       - Set files with the nscd_unit_file_t type, if you want  to  treat  the
198       files as nscd unit content.
199
200
201
202       nscd_var_run_t
203
204       - Set files with the nscd_var_run_t type, if you want to store the nscd
205       files under the /run or /var/run directory.
206
207
208       Paths:
209            /var/db/nscd(/.*)?,  /var/run/nscd(/.*)?,   /var/cache/nscd(/.*)?,
210            /var/run/nscd.pid, /var/run/.nscd_socket
211
212
213       Note:  File context can be temporarily modified with the chcon command.
214       If you want to permanently change the file context you need to use  the
215       semanage fcontext command.  This will modify the SELinux labeling data‐
216       base.  You will need to use restorecon to apply the labels.
217
218

COMMANDS

220       semanage fcontext can also be used to manipulate default  file  context
221       mappings.
222
223       semanage  permissive  can  also  be used to manipulate whether or not a
224       process type is permissive.
225
226       semanage module can also be used to enable/disable/install/remove  pol‐
227       icy modules.
228
229       semanage boolean can also be used to manipulate the booleans
230
231
232       system-config-selinux is a GUI tool available to customize SELinux pol‐
233       icy settings.
