6 ccs_selinux - Security Enhanced Linux Policy for the ccs processes
7
9 Security-Enhanced Linux secures the ccs processes via flexible manda‐
10 tory access control.
11 The ccs processes execute with the ccs_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep ccs_t
19
23 The ccs_t SELinux type can be entered via the ccs_exec_t file type.
24 The default entrypoint paths for the ccs_t domain are the following:
26 /sbin/ccsd, /usr/sbin/ccsd
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 ccs policy is very flexible allowing users to setup their ccs processes
37 in as secure a method as possible.
38 The following process types are defined for ccs:
40 ccs_t
42 Note: semanage permissive -a ccs_t can be used to make the process type
44 ccs_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. ccs
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run ccs with the tightest access possible.
52 If you want to allow all domains to execute in fips_mode, you must turn
56 on the fips_mode boolean. Enabled by default.
57 setsebool -P fips_mode 1
59 If you want to allow confined applications to use nscd shared memory,
63 you must turn on the nscd_use_shm boolean. Enabled by default.
64 setsebool -P nscd_use_shm 1
66
70 The SELinux process type ccs_t can manage files labeled with the fol‐
71 lowing file types. The paths listed are the default paths for these
72 file types. Note the processes UID still need to have DAC permissions.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 Policy governs the access confined processes have to these files.
139 SELinux ccs policy is very flexible allowing users to setup their ccs
140 processes in as secure a method as possible.
141 STANDARD FILE CONTEXT
143 SELinux defines the file context types for the ccs, if you wanted to
145 store files with these types in a diffent paths, you need to execute
146 the semanage command to specify alternate labeling and then use re‐
147 storecon to put the labels on disk.
148 semanage fcontext -a -t ccs_var_run_t '/srv/myccs_content(/.*)?'
150 restorecon -R -v /srv/myccs_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for ccs:
156 ccs_exec_t
160 - Set files with the ccs_exec_t type, if you want to transition an exe‐
162 cutable to the ccs_t domain.
163 Paths:
166 /sbin/ccsd, /usr/sbin/ccsd
167 ccs_initrc_exec_t
170 - Set files with the ccs_initrc_exec_t type, if you want to transition
172 an executable to the ccs_initrc_t domain.
173 ccs_tmp_t
177 - Set files with the ccs_tmp_t type, if you want to store ccs temporary
179 files in the /tmp directories.
180 ccs_tmpfs_t
184 - Set files with the ccs_tmpfs_t type, if you want to store ccs files
186 on a tmpfs file system.
187 ccs_var_lib_t
191 - Set files with the ccs_var_lib_t type, if you want to store the ccs
193 files under the /var/lib directory.
194 ccs_var_log_t
198 - Set files with the ccs_var_log_t type, if you want to treat the data
200 as ccs var log data, usually stored under the /var/log directory.
201 ccs_var_run_t
205 - Set files with the ccs_var_run_t type, if you want to store the ccs
207 files under the /run or /var/run directory.
208 Paths:
211 /var/run/cluster/((ccs)|(ccsd)).pid, /var/run/clus‐
212 ter/((ccs)|(ccsd)).sock
213 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
