6 collectd_selinux - Security Enhanced Linux Policy for the collectd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the collectd processes via flexible
11 mandatory access control.
12
13 The collectd processes execute with the collectd_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 collectd_t
20
21
22
24 The collectd_t SELinux type can be entered via the file_type, col‐
25 lectd_exec_t, unlabeled_t, proc_type, filesystem_type, mtrr_device_t,
26 sysctl_type file types.
27
28 The default entrypoint paths for the collectd_t domain are the follow‐
29 ing:
30
31 all files on the system, /usr/sbin/collectd, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 collectd policy is very flexible allowing users to setup their collectd
41 processes in as secure a method as possible.
42
43 The following process types are defined for collectd:
44
45 collectd_t
46
47 Note: semanage permissive -a collectd_t can be used to make the process
48 type collectd_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. col‐
55 lectd policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run collectd with the tightest access
57 possible.
58
59
60
61 If you want to determine whether collectd can connect to the network
62 using TCP, you must turn on the collectd_tcp_network_connect boolean.
63 Disabled by default.
64
65 setsebool -P collectd_tcp_network_connect 1
66
67
68
69 If you want to allow all daemons to write corefiles to /, you must turn
70 on the allow_daemons_dump_core boolean. Disabled by default.

94 setsebool -P allow_domain_fd_use 1
95
96
97
98 If you want to allow unconfined executables to make their heap memory
99 executable. Doing this is a really bad idea. Probably indicates a
100 badly coded executable, but could indicate an attack. This executable
101 should be reported in bugzilla, you must turn on the allow_execheap
102 boolean. Disabled by default.
103
104 setsebool -P allow_execheap 1
105
106
107
108 If you want to allow unconfined executables to map a memory region as

111 boolean. Enabled by default.
112
113 setsebool -P allow_execmem 1
114

122
123
124
125 If you want to allow unconfined executables to make their stack exe‐
126 cutable. This should never, ever be necessary. Probably indicates a
127 badly coded executable, but could indicate an attack. This executable
128 should be reported in bugzilla), you must turn on the allow_execstack
129 boolean. Enabled by default.
130
131 setsebool -P allow_execstack 1
132
133
134

166
167 setsebool -P global_ssp 1
168
169
170
171 If you want to enable support for upstart as the init program, you must
172 turn on the init_upstart boolean. Enabled by default.
173
174 setsebool -P init_upstart 1
175
176
177
178 If you want to allow certain domains to map low memory in the kernel,
179 you must turn on the mmap_low_allowed boolean. Disabled by default.
180
181 setsebool -P mmap_low_allowed 1
182
183
184
185 If you want to boolean to determine whether the system permits loading
186 policy, setting enforcing mode, and changing boolean values. Set this
187 to true and you have to reboot to set it back, you must turn on the

202 SELinux defines port types to represent TCP and UDP ports.
203
204 You can see the types associated with a port by using the following
205 command:
206
207 semanage port -l
208
209
210 Policy governs the access confined processes have to these ports.
211 SELinux collectd policy is very flexible allowing users to setup their
212 collectd processes in as secure a method as possible.
213
214 The following port types are defined for collectd:
215
216
217 collectd_port_t
218
219
220
221 Default Defined Ports:
222 udp 25826
223
225 The SELinux process type collectd_t can manage files labeled with the
226 following file types. The paths listed are the default paths for these
227 file types. Note the processes UID still need to have DAC permissions.
228
229 file_type
230
231 all files on the system
232
233
235 SELinux requires files to have an extended attribute to define the file
236 type.
237
238 You can see the context of a file using the -Z option to ls
239
240 Policy governs the access confined processes have to these files.
241 SELinux collectd policy is very flexible allowing users to setup their
242 collectd processes in as secure a method as possible.
243
244 STANDARD FILE CONTEXT
245
246 SELinux defines the file context types for the collectd, if you wanted
247 to store files with these types in a diffent paths, you need to execute
248 the semanage command to sepecify alternate labeling and then use
249 restorecon to put the labels on disk.
250
251 semanage fcontext -a -t collectd_var_run_t '/srv/mycollectd_con‐
252 tent(/.*)?'
253 restorecon -R -v /srv/mycollectd_content
254
255 Note: SELinux often uses regular expressions to specify labels that
256 match multiple files.
257
258 The following file types are defined for collectd:
259
260
261
262 collectd_exec_t
263
264 - Set files with the collectd_exec_t type, if you want to transition an
265 executable to the collectd_t domain.
266
267
268
269 collectd_initrc_exec_t
270
271 - Set files with the collectd_initrc_exec_t type, if you want to tran‐
272 sition an executable to the collectd_initrc_t domain.
273
274
275
276 collectd_script_tmp_t
277
278 - Set files with the collectd_script_tmp_t type, if you want to store
279 collectd script temporary files in the /tmp directories.
280
281
282
283 collectd_var_lib_t
284
285 - Set files with the collectd_var_lib_t type, if you want to store the
286 collectd files under the /var/lib directory.
287
288
289
290 collectd_var_run_t
291
292 - Set files with the collectd_var_run_t type, if you want to store the
293 collectd files under the /run or /var/run directory.
294
295
296
297 Note: File context can be temporarily modified with the chcon command.
298 If you want to permanently change the file context you need to use the
299 semanage fcontext command. This will modify the SELinux labeling data‐
300 base. You will need to use restorecon to apply the labels.
301
302
304 semanage fcontext can also be used to manipulate default file context
305 mappings.
306
307 semanage permissive can also be used to manipulate whether or not a
308 process type is permissive.
309
310 semanage module can also be used to enable/disable/install/remove pol‐
311 icy modules.
312
313 semanage port can also be used to manipulate the port definitions
314
315 semanage boolean can also be used to manipulate the booleans
316
317
318 system-config-selinux is a GUI tool available to customize SELinux pol‐
319 icy settings.
