amavis_selinux(8) amavis SELinux Policy documentation amavis_selinux(8)NAMEamavis_selinux - Security Enhanced Linux Policy for the amavis pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the amavis processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
amavis_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
amavis_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 amavis_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 amavis policy is very flexible allowing users to setup their
amavis processes in as secure a method as possible.
The following file types are defined for amavis:
amavis_etc_t
- Set files with the amavis_etc_t type, if you want to store amavis
files in the /etc directories.
Paths:
/etc/amavis.conf, /etc/amavisd(/.*)?
amavis_exec_t
- Set files with the amavis_exec_t type, if you want to transition an
executable to the amavis_t domain.
Paths:
/usr/sbin/amavisd.*, /usr/lib/AntiVir/antivir
amavis_initrc_exec_t
- Set files with the amavis_initrc_exec_t type, if you want to transi‐
tion an executable to the amavis_initrc_t domain.
Paths:
/etc/rc.d/init.d/amavis, /etc/rc.d/init.d/amavisd-snmp
amavis_quarantine_t
- Set files with the amavis_quarantine_t type, if you want to treat the
files as amavis quarantine data.
amavis_spool_t
- Set files with the amavis_spool_t type, if you want to store the
amavis files under the /var/spool directory.
amavis_tmp_t
- Set files with the amavis_tmp_t type, if you want to store amavis
temporary files in the /tmp directories.
amavis_var_lib_t
- Set files with the amavis_var_lib_t type, if you want to store the
amavis files under the /var/lib directory.
Paths:
/var/lib/amavis(/.*)?, /var/opt/f-secure(/.*)?, /var/amavis(/.*)?
amavis_var_log_t
- Set files with the amavis_var_log_t type, if you want to treat the
data as amavis var log data, usually stored under the /var/log direc‐
tory.
amavis_var_run_t
- Set files with the amavis_var_run_t type, if you want to store the
amavis files under the /run directory.
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 amavis policy is very flexible allowing users to setup their
amavis processes in as secure a method as possible.
The following port types are defined for amavis:
amavisd_recv_port_t
Default Defined Ports:
tcp 10024
amavisd_send_port_t
Default Defined Ports:
tcp 10025
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
amavis policy is very flexible allowing users to setup their amavis
processes in as secure a method as possible.
The following process types are defined for amavis:
amavis_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.
