Security-Enhanced Linux secures the auditd processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the auditadm_t, auditadm_gkeyringd_t, auditadm_su_t, auditd_t, auditadm_sudo_t, auditadm_screen_t, auditadm_wine_t, auditadm_seunshare_t, auditadm_dbusd_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the auditadm_t, auditadm_gkeyringd_t, auditadm_su_t, auditd_t, auditadm_sudo_t, auditadm_screen_t, auditadm_wine_t, auditadm_seunshare_t, auditadm_dbusd_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux auditd policy is very flexible allowing users to setup their auditd processes in as secure a method as possible.
The following file types are defined for auditd:
auditd_etc_t
- Set files with the auditd_etc_t type, if you want to store auditd files in the /etc directories.
auditd_exec_t
- Set files with the auditd_exec_t type, if you want to transition an executable to the auditd_t domain.
auditd_initrc_exec_t
- Set files with the auditd_initrc_exec_t type, if you want to transition an executable to the auditd_initrc_t domain.
auditd_log_t
- Set files with the auditd_log_t type, if you want to treat the data as auditd log data, usually stored under the /var/log directory.
auditd_unit_file_t
- Set files with the auditd_unit_file_t type, if you want to treat the files as auditd unit content.
auditd_var_run_t
- Set files with the auditd_var_run_t type, if you want to store the auditd files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux auditd policy is very flexible allowing users to setup their auditd processes in as secure a method as possible.
The following port types are defined for auditd:
Default Defined Ports: tcp 60
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux auditd policy is very flexible allowing users to setup their auditd processes in as secure a method as possible.
The following process types are defined for auditd:
auditadm_su_t, auditadm_seunshare_t, auditadm_dbusd_t, auditadm_t, auditadm_sudo_t, auditadm_wine_t, auditadm_screen_t, auditadm_gkeyringd_t, auditd_t, auditctl_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
