clamd_selinux(8) clamd SELinux Policy documentation clamd_selinux(8)NAMEclamd_selinux - Security Enhanced Linux Policy for the clamd processes
DESCRIPTION
Security-Enhanced Linux secures the clamd processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. clamd
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run clamd 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
If you want to allow clamd to use JIT compile, you must turn on the
clamd_use_jit boolean.
setsebool -P clamd_use_jit 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the clamd_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
clamd_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 clamd_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 clamd policy is very flexible allowing users to setup their
clamd processes in as secure a method as possible.
The following file types are defined for clamd:
clamd_etc_t
- Set files with the clamd_etc_t type, if you want to store clamd files
in the /etc directories.
clamd_exec_t
- Set files with the clamd_exec_t type, if you want to transition an
executable to the clamd_t domain.
Paths:
/usr/sbin/clamd, /usr/sbin/clamav-milter
clamd_initrc_exec_t
- Set files with the clamd_initrc_exec_t type, if you want to transi‐
tion an executable to the clamd_initrc_t domain.
clamd_tmp_t
- Set files with the clamd_tmp_t type, if you want to store clamd tem‐
porary files in the /tmp directories.
clamd_unit_file_t
- Set files with the clamd_unit_file_t type, if you want to treat the
files as clamd unit content.
clamd_var_lib_t
- Set files with the clamd_var_lib_t type, if you want to store the
clamd files under the /var/lib directory.
Paths:
/var/lib/clamd.*, /var/clamav(/.*)?, /var/lib/clamav(/.*)?
clamd_var_log_t
- Set files with the clamd_var_log_t type, if you want to treat the
data as clamd var log data, usually stored under the /var/log direc‐
tory.
Paths:
/var/log/clamav.*, /var/log/clamd.*
clamd_var_run_t
- Set files with the clamd_var_run_t type, if you want to store the
clamd files under the /run directory.
Paths:
/var/run/amavis(d)?/clamd.pid, /var/run/clamd.*, /var/run/cla‐
mav.*, /var/spool/MailScanner(/.*)?, /var/spool/amavisd/clamd.sock
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 clamd policy is very flexible allowing users to setup their
clamd processes in as secure a method as possible.
The following port types are defined for clamd:
clamd_port_t
Default Defined Ports:
tcp 3310
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
clamd policy is very flexible allowing users to setup their clamd pro‐
cesses in as secure a method as possible.
The following process types are defined for clamd:
clamd_t, clamscan_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
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
