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 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 For example:
18 ps -eZ | grep memcached_t
20
24 The memcached_t SELinux type can be entered via the memcached_exec_t
25 file type.
26 The default entrypoint paths for the memcached_t domain are the follow‐
28 ing:
29 /usr/bin/memcached
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for memcached:
43 memcached_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 SELinux defines port types to represent TCP and UDP ports.
69 You can see the types associated with a port by using the following
71 command:
72 semanage port -l
74 Policy governs the access confined processes have to these ports.
77 SELinux memcached policy is very flexible allowing users to setup their
78 memcached processes in as secure a method as possible.
79 The following port types are defined for memcached:
81 memcache_port_t
84 Default Defined Ports:
88 tcp 11211
89 udp 11211
90
92 The SELinux process type memcached_t can manage files labeled with the
93 following file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.
95 cluster_conf_t

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux memcached policy is very flexible allowing users to setup their
145 memcached processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the memcached, if you wanted
150 to store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t memcached_var_run_t '/srv/mymemcached_con‐
155 tent(/.*)?'
156 restorecon -R -v /srv/mymemcached_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for memcached:
162 memcached_exec_t
166 - Set files with the memcached_exec_t type, if you want to transition
168 an executable to the memcached_t domain.
169 memcached_initrc_exec_t
173 - Set files with the memcached_initrc_exec_t type, if you want to tran‐
175 sition an executable to the memcached_initrc_t domain.
176 memcached_var_run_t
180 - Set files with the memcached_var_run_t type, if you want to store the
182 memcached files under the /run or /var/run directory.
183 Paths:
186 /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
187 Note: File context can be temporarily modified with the chcon command.
190 If you want to permanently change the file context you need to use the
191 semanage fcontext command. This will modify the SELinux labeling data‐
192 base. You will need to use restorecon to apply the labels.
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage port can also be used to manipulate the port definitions
206 semanage boolean can also be used to manipulate the booleans
208 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
