6 ibacm_selinux - Security Enhanced Linux Policy for the ibacm processes
7
9 Security-Enhanced Linux secures the ibacm processes via flexible manda‐
10 tory access control.
11 The ibacm processes execute with the ibacm_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep ibacm_t
19
23 The ibacm_t SELinux type can be entered via the ibacm_exec_t file type.
24 The default entrypoint paths for the ibacm_t domain are the following:
26 /usr/sbin/ibacm
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 ibacm policy is very flexible allowing users to setup their ibacm pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for ibacm:
40 ibacm_t
42 Note: semanage permissive -a ibacm_t can be used to make the process
44 type ibacm_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. ibacm
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ibacm 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 The SELinux process type ibacm_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux ibacm policy is very flexible allowing users to setup their
151 ibacm processes in as secure a method as possible.
152 STANDARD FILE CONTEXT
154 SELinux defines the file context types for the ibacm, if you wanted to
156 store files with these types in a diffent paths, you need to execute
157 the semanage command to sepecify alternate labeling and then use re‐
158 storecon to put the labels on disk.
159 semanage fcontext -a -t ibacm_tmpfs_t '/srv/myibacm_content(/.*)?'
161 restorecon -R -v /srv/myibacm_content
162 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165 The following file types are defined for ibacm:
167 ibacm_conf_t
171 - Set files with the ibacm_conf_t type, if you want to treat the files
173 as ibacm configuration data, usually stored under the /etc directory.
174 ibacm_exec_t
178 - Set files with the ibacm_exec_t type, if you want to transition an
180 executable to the ibacm_t domain.
181 ibacm_log_t
185 - Set files with the ibacm_log_t type, if you want to treat the data as
187 ibacm log data, usually stored under the /var/log directory.
188 ibacm_tmpfs_t
192 - Set files with the ibacm_tmpfs_t type, if you want to store ibacm
194 files on a tmpfs file system.
195 ibacm_var_run_t
199 - Set files with the ibacm_var_run_t type, if you want to store the
201 ibacm files under the /run or /var/run directory.
202 Paths:
205 /var/run/ibacm.*, /var/run/ibacm.*, /var/run/ibacm-unix.*
206 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
