auditd_selinux(8) auditd SELinux Policy documentation auditd_selinux(8)NAMEauditd_selinux - Security Enhanced Linux Policy for the auditd pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the auditd processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the audi‐
tadm_t, auditadm_gkeyringd_t, auditadm_su_t, auditd_t, auditadm_sudo_t,
auditadm_screen_t, auditadm_wine_t, auditadm_seunshare_t, audi‐
tadm_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, audi‐
tadm_sudo_t, auditadm_screen_t, auditadm_wine_t, auditadm_seunshare_t,
auditadm_dbusd_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the auditadm_t, audi‐
tadm_gkeyringd_t, auditadm_su_t, auditd_t, auditadm_sudo_t, audi‐
tadm_screen_t, auditadm_wine_t, auditadm_seunshare_t, auditadm_dbusd_t,
you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
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.
Paths:
/sbin/auditd, /usr/sbin/auditd
auditd_initrc_exec_t
- Set files with the auditd_initrc_exec_t type, if you want to transi‐
tion 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.
Paths:
/var/log/audit(/.*)?, /var/log/audit.log
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.
Paths:
/var/run/audit_events, /var/run/auditd_sock, /var/run/auditd.pid
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
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:
audit_port_t
Default Defined Ports:
tcp 60
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
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.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
