mscan_selinux(8) mscan SELinux Policy documentation mscan_selinux(8)NAMEmscan_selinux - Security Enhanced Linux Policy for the mscan processes
DESCRIPTION
Security-Enhanced Linux secures the mscan processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. mscan
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run mscan with the tightest access possible.
If you want to allow clamscan to read user conten, you must turn on the
clamscan_read_user_content boolean.
setsebool -P clamscan_read_user_content 1
If you want to allow clamscan to non security files on a syste, you
must turn on the clamscan_can_scan_system boolean.
setsebool -P clamscan_can_scan_system 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the mscan_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
mscan_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 mscan_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 mscan policy is very flexible allowing users to setup their
mscan processes in as secure a method as possible.
The following file types are defined for mscan:
mscan_etc_t
- Set files with the mscan_etc_t type, if you want to store mscan files
in the /etc directories.
Paths:
/etc/sysconfig/MailScanner, /etc/MailScanner(/.*)?, /etc/syscon‐
fig/update_spamassassin
mscan_exec_t
- Set files with the mscan_exec_t type, if you want to transition an
executable to the mscan_t domain.
mscan_initrc_exec_t
- Set files with the mscan_initrc_exec_t type, if you want to transi‐
tion an executable to the mscan_initrc_t domain.
mscan_tmp_t
- Set files with the mscan_tmp_t type, if you want to store mscan tem‐
porary files in the /tmp directories.
mscan_var_run_t
- Set files with the mscan_var_run_t type, if you want to store the
mscan 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.
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
mscan policy is very flexible allowing users to setup their mscan pro‐
cesses in as secure a method as possible.
The following process types are defined for mscan:
mscan_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 boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
