6 dccm_selinux - Security Enhanced Linux Policy for the dccm processes
7
9 Security-Enhanced Linux secures the dccm processes via flexible manda‐
10 tory access control.
11
12 The dccm processes execute with the dccm_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 dccm_t
19
20
21
23 The dccm_t SELinux type can be entered via the dccm_exec_t file type.
24
25 The default entrypoint paths for the dccm_t domain are the following:
26
27 /usr/sbin/dccm, /usr/libexec/dcc/dccm
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 dccm policy is very flexible allowing users to setup their dccm pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for dccm:
40
41 dccm_t
42
43 Note: semanage permissive -a dccm_t can be used to make the process
44 type dccm_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
50 SELinux policy is customizable based on least access required. dccm
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run dccm with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux dccm policy is very flexible allowing users to setup their dccm
103 processes in as secure a method as possible.
104
105 The following port types are defined for dccm:
106
107
108 dccm_port_t
109
110
111
112 Default Defined Ports:
113 tcp 5679
114 udp 5679
115
117 The SELinux process type dccm_t can manage files labeled with the fol‐
118 lowing file types. The paths listed are the default paths for these
119 file types. Note the processes UID still need to have DAC permissions.

177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux dccm policy is very flexible allowing users to setup their dccm
184 processes in as secure a method as possible.
185
186 STANDARD FILE CONTEXT
187
188 SELinux defines the file context types for the dccm, if you wanted to
189 store files with these types in a diffent paths, you need to execute
190 the semanage command to sepecify alternate labeling and then use
191 restorecon to put the labels on disk.
192
193 semanage fcontext -a -t dccm_var_run_t '/srv/mydccm_content(/.*)?'
194 restorecon -R -v /srv/mydccm_content
195
196 Note: SELinux often uses regular expressions to specify labels that
197 match multiple files.
198
199 The following file types are defined for dccm:
200
201
202
203 dccm_exec_t
204
205 - Set files with the dccm_exec_t type, if you want to transition an
206 executable to the dccm_t domain.
207
208
209 Paths:
210 /usr/sbin/dccm, /usr/libexec/dcc/dccm
211
212
213 dccm_tmp_t
214
215 - Set files with the dccm_tmp_t type, if you want to store dccm tempo‐
216 rary files in the /tmp directories.
217
218
219
220 dccm_var_run_t
221
222 - Set files with the dccm_var_run_t type, if you want to store the dccm
223 files under the /run or /var/run directory.
224
225
226
227 Note: File context can be temporarily modified with the chcon command.
228 If you want to permanently change the file context you need to use the
229 semanage fcontext command. This will modify the SELinux labeling data‐
230 base. You will need to use restorecon to apply the labels.
231
232
234 semanage fcontext can also be used to manipulate default file context
235 mappings.
236
237 semanage permissive can also be used to manipulate whether or not a
238 process type is permissive.
239
240 semanage module can also be used to enable/disable/install/remove pol‐
241 icy modules.
242
243 semanage port can also be used to manipulate the port definitions
244
245 semanage boolean can also be used to manipulate the booleans
246
247
248 system-config-selinux is a GUI tool available to customize SELinux pol‐
249 icy settings.
