NAME

amavis_selinux - Security Enhanced Linux Policy for the amavis processes  

DESCRIPTION

Security-Enhanced Linux secures the amavis processes via flexible mandatory access control.

 

BOOLEANS

SELinux policy is customizable based on least access required. amavis policy is extremely flexible and has several booleans that allow you to manipulate the policy and run amavis with the tightest access possible.

If you want to allow amavis to use JIT compiler, you must turn on the amavis_use_jit boolean.

setsebool -P amavis_use_jit 1

 

NSSWITCH DOMAIN

If you want to allow users to resolve user passwd entries directly from ldap rather then 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 kerberos_enabled boolean.

setsebool -P kerberos_enabled 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 lsP 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/amavisd(/.*)?, /etc/amavis(d)?.conf

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 transition 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 directory.

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 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.

 

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 pro
