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 users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1
89
93 The SELinux process type ibacm_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux ibacm policy is very flexible allowing users to setup their
158 ibacm processes in as secure a method as possible.
159 STANDARD FILE CONTEXT
161 SELinux defines the file context types for the ibacm, if you wanted to
163 store files with these types in a diffent paths, you need to execute
164 the semanage command to sepecify alternate labeling and then use
165 restorecon to put the labels on disk.
166 semanage fcontext -a -t ibacm_tmpfs_t '/srv/myibacm_content(/.*)?'
168 restorecon -R -v /srv/myibacm_content
169 Note: SELinux often uses regular expressions to specify labels that
171 match multiple files.
172 The following file types are defined for ibacm:
174 ibacm_conf_t
178 - Set files with the ibacm_conf_t type, if you want to treat the files
180 as ibacm configuration data, usually stored under the /etc directory.
181 ibacm_exec_t
185 - Set files with the ibacm_exec_t type, if you want to transition an
187 executable to the ibacm_t domain.
188 ibacm_log_t
192 - Set files with the ibacm_log_t type, if you want to treat the data as
194 ibacm log data, usually stored under the /var/log directory.
195 ibacm_tmpfs_t
199 - Set files with the ibacm_tmpfs_t type, if you want to store ibacm
201 files on a tmpfs file system.
202 ibacm_var_run_t
206 - Set files with the ibacm_var_run_t type, if you want to store the
208 ibacm files under the /run or /var/run directory.
209 Paths:
212 /var/run/ibacm.*, /var/run/ibacm.*, /var/run/ibacm-unix.*
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.
