NAME
amavis_selinux - Security Enhanced Linux Policy for the amavis processesDESCRIPTION
SELinux Linux secures amavis ( Daemon that interfaces mail transfer agents and content checkers, such as virus scanners. ) processes via flexible mandatory access control.
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/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/lib(64)?/AntiVir/antivir, /usr/sbin/amavisd.*
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.
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/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 8021
- amavisd_send_port_t
-
Default Defined Ports: tcp 8021
PROCESS TYPES
SELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psP 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 policy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux policy settings.
