6 memcached_selinux - Security Enhanced Linux Policy for the memcached
7 processes
8
10 Security-Enhanced Linux secures the memcached processes via flexible
11 mandatory access control.
12
13 The memcached processes execute with the memcached_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 memcached_t
20
21
22
24 The memcached_t SELinux type can be entered via the memcached_exec_t
25 file type.
26
27 The default entrypoint paths for the memcached_t domain are the follow‐
28 ing:
29
30 /usr/bin/memcached
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 memcached policy is very flexible allowing users to setup their mem‐
40 cached processes in as secure a method as possible.
41
42 The following process types are defined for memcached:
43
44 memcached_t
45
46 Note: semanage permissive -a memcached_t can be used to make the
47 process type memcached_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. mem‐
54 cached policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run memcached with the tightest access
56 possible.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
83 SELinux defines port types to represent TCP and UDP ports.
84
85 You can see the types associated with a port by using the following
86 command:
87
88 semanage port -l
89
90
91 Policy governs the access confined processes have to these ports.
92 SELinux memcached policy is very flexible allowing users to setup their
93 memcached processes in as secure a method as possible.
94
95 The following port types are defined for memcached:
96
97
98 memcache_port_t
99
100
101
102 Default Defined Ports:
103 tcp 11211
104 udp 11211
105
107 The SELinux process type memcached_t can manage files labeled with the
108 following file types. The paths listed are the default paths for these
109 file types. Note the processes UID still need to have DAC permissions.

168 SELinux requires files to have an extended attribute to define the file
169 type.
170
171 You can see the context of a file using the -Z option to ls
172
173 Policy governs the access confined processes have to these files.
174 SELinux memcached policy is very flexible allowing users to setup their
175 memcached processes in as secure a method as possible.
176
177 STANDARD FILE CONTEXT
178
179 SELinux defines the file context types for the memcached, if you wanted
180 to store files with these types in a different paths, you need to exe‐
181 cute the semanage command to specify alternate labeling and then use
182 restorecon to put the labels on disk.
183
184 semanage fcontext -a -t memcached_exec_t '/srv/memcached/content(/.*)?'
185 restorecon -R -v /srv/mymemcached_content
186
187 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189
190 The following file types are defined for memcached:
191
192
193
194 memcached_exec_t
195
196 - Set files with the memcached_exec_t type, if you want to transition
197 an executable to the memcached_t domain.
198
199
200
201 memcached_initrc_exec_t
202
203 - Set files with the memcached_initrc_exec_t type, if you want to tran‐
204 sition an executable to the memcached_initrc_t domain.
205
206
207
208 memcached_var_run_t
209
210 - Set files with the memcached_var_run_t type, if you want to store the
211 memcached files under the /run or /var/run directory.
212
213
214 Paths:
215 /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
216
217
218 Note: File context can be temporarily modified with the chcon command.
219 If you want to permanently change the file context you need to use the
220 semanage fcontext command. This will modify the SELinux labeling data‐
221 base. You will need to use restorecon to apply the labels.
222
223
225 semanage fcontext can also be used to manipulate default file context
226 mappings.
227
228 semanage permissive can also be used to manipulate whether or not a
229 process type is permissive.
230
231 semanage module can also be used to enable/disable/install/remove pol‐
232 icy modules.
233
234 semanage port can also be used to manipulate the port definitions
235
236 semanage boolean can also be used to manipulate the booleans
237
238
239 system-config-selinux is a GUI tool available to customize SELinux pol‐
240 icy settings.
