6 bcfg2_selinux - Security Enhanced Linux Policy for the bcfg2 processes
7
9 Security-Enhanced Linux secures the bcfg2 processes via flexible manda‐
10 tory access control.
11 The bcfg2 processes execute with the bcfg2_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 bcfg2_t
19
23 The bcfg2_t SELinux type can be entered via the bcfg2_exec_t file type.
24 The default entrypoint paths for the bcfg2_t domain are the following:
26 /usr/sbin/bcfg2-server
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 bcfg2 policy is very flexible allowing users to setup their bcfg2 pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for bcfg2:
40 bcfg2_t
42 Note: semanage permissive -a bcfg2_t can be used to make the process
44 type bcfg2_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. bcfg2
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run bcfg2 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. Enabled by default.
87 setsebool -P nscd_use_shm 1

93 The SELinux process type bcfg2_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.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux bcfg2 policy is very flexible allowing users to setup their
149 bcfg2 processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the bcfg2, if you wanted to
154 store files with these types in a diffent paths, you need to execute
155 the semanage command to sepecify alternate labeling and then use
156 restorecon to put the labels on disk.
157 semanage fcontext -a -t bcfg2_var_run_t '/srv/mybcfg2_content(/.*)?'
159 restorecon -R -v /srv/mybcfg2_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for bcfg2:
165 bcfg2_exec_t
169 - Set files with the bcfg2_exec_t type, if you want to transition an
171 executable to the bcfg2_t domain.
172 bcfg2_initrc_exec_t
176 - Set files with the bcfg2_initrc_exec_t type, if you want to transi‐
178 tion an executable to the bcfg2_initrc_t domain.
179 bcfg2_unit_file_t
183 - Set files with the bcfg2_unit_file_t type, if you want to treat the
185 files as bcfg2 unit content.
186 bcfg2_var_lib_t
190 - Set files with the bcfg2_var_lib_t type, if you want to store the
192 bcfg2 files under the /var/lib directory.
193 bcfg2_var_run_t
197 - Set files with the bcfg2_var_run_t type, if you want to store the
199 bcfg2 files under the /run or /var/run directory.
200 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
