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 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 For example:
17 ps -eZ | grep dccm_t
19
23 The dccm_t SELinux type can be entered via the dccm_exec_t file type.
24 The default entrypoint paths for the dccm_t domain are the following:
26 /usr/sbin/dccm, /usr/libexec/dcc/dccm
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for dccm:
40 dccm_t
42 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
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 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 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 SELinux defines port types to represent TCP and UDP ports.
72 You can see the types associated with a port by using the following
74 command:
75 semanage port -l
77 Policy governs the access confined processes have to these ports.
80 SELinux dccm policy is very flexible allowing users to setup their dccm
81 processes in as secure a method as possible.
82 The following port types are defined for dccm:
84 dccm_port_t
87 Default Defined Ports:
91 tcp 5679
92 udp 5679
93
95 The SELinux process type dccm_t can manage files labeled with the fol‐
96 lowing file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.

152 SELinux requires files to have an extended attribute to define the file
153 type.
154 You can see the context of a file using the -Z option to ls
156 Policy governs the access confined processes have to these files.
158 SELinux dccm policy is very flexible allowing users to setup their dccm
159 processes in as secure a method as possible.
160 STANDARD FILE CONTEXT
162 SELinux defines the file context types for the dccm, if you wanted to
164 store files with these types in a diffent paths, you need to execute
165 the semanage command to sepecify alternate labeling and then use
166 restorecon to put the labels on disk.
167 semanage fcontext -a -t dccm_var_run_t '/srv/mydccm_content(/.*)?'
169 restorecon -R -v /srv/mydccm_content
170 Note: SELinux often uses regular expressions to specify labels that
172 match multiple files.
173 The following file types are defined for dccm:
175 dccm_exec_t
179 - Set files with the dccm_exec_t type, if you want to transition an
181 executable to the dccm_t domain.
182 Paths:
185 /usr/sbin/dccm, /usr/libexec/dcc/dccm
186 dccm_tmp_t
189 - Set files with the dccm_tmp_t type, if you want to store dccm tempo‐
191 rary files in the /tmp directories.
192 dccm_var_run_t
196 - Set files with the dccm_var_run_t type, if you want to store the dccm
198 files under the /run or /var/run directory.
199 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217 semanage port can also be used to manipulate the port definitions
219 semanage boolean can also be used to manipulate the booleans
221 system-config-selinux is a GUI tool available to customize SELinux pol‐
224 icy settings.
