NAME
       antivirus_selinux  -  Security  Enhanced Linux Policy for the antivirus
       processes

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

       The  antivirus processes execute with the antivirus_t SELinux type. You
       can check if you have these processes running by executing the ps  com‐
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep antivirus_t

ENTRYPOINTS
       The  antivirus_t	 SELinux  type can be entered via the antivirus_exec_t
       file type.

       The default entrypoint paths for the antivirus_t domain are the follow‐
       ing:

       /usr/sbin/amavisd.*,	    /usr/sbin/clamd,	    /usr/bin/clamscan,
       /usr/bin/clamdscan,    /usr/bin/freshclam,     /usr/sbin/clamav-milter,
       /usr/lib/AntiVir/antivir

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
       antivirus  policy  is  very  flexible  allowing	users  to  setup their
       antivirus processes in as secure a method as possible.

       The following process types are defined for antivirus:

       antivirus_t

       Note: semanage permissive -a  antivirus_t  can  be  used	 to  make  the
       process	type  antivirus_t  permissive. SELinux does not deny access to
       permissive process types, but the AVC (SELinux  denials)	 messages  are
       still generated.

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

       If you want to allow antivirus programs to read non security files on a
       system,	you  must  turn on the antivirus_can_scan_system boolean. Dis‐
       abled by default.

       setsebool -P antivirus_can_scan_system 1

       If you want to determine whether can antivirus programs	use  JIT  com‐
       piler,  you  must  turn	on  the antivirus_use_jit boolean. Disabled by
       default.

       setsebool -P antivirus_use_jit 1

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If  you	want  to allow confined applications to run with kerberos, you
       must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with	NIS,  you  must	 turn  on  the
       nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If  you	want to allow confined applications to use nscd shared memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap rather then using a sssd server for the antivirus_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
       antivirus_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The  SELinux process type antivirus_t can manage files labeled with the
       following file types.  The paths listed are the default paths for these
       file types.  Note the processes UID still need to have DAC permissions.

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 antivirus policy is very flexible allowing users to setup their
       antivirus processes in as secure a method as possible.

       EQUIVALENCE DIRECTORIES

       antivirus policy stores data with multiple different file context types
       under  the  /var/run/amavis(d)?	directory.  If you would like to store
       the data in a different directory you can use the semanage  command  to
       create  an equivalence mapping.	If you wanted to store this data under
       the /srv dirctory you would execute the following command:

       semanage fcontext -a -e /var/run/amavis(d)? /srv/amavis(d)?
       restorecon -R -v /srv/amavis(d)?

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the antivirus, if you wanted
       to store files with these types in a diffent paths, you need to execute
       the semanage command  to	 sepecify  alternate  labeling	and  then  use
       restorecon to put the labels on disk.

       semanage fcontext -a -t antivirus_conf_t '/srv/antivirus/content(/.*)?'
       restorecon -R -v /srv/myantivirus_content

       Note:  SELinux  often  uses  regular expressions to specify labels that
       match multiple files.

       The following file types are defined for antivirus:

       antivirus_conf_t

       - Set files with the antivirus_conf_t type, if you want	to  treat  the
       files  as  antivirus  configuration data, usually stored under the /etc
       directory.

       Paths:
	    /etc/amavis(d)?.conf, /etc/amavisd(/.*)?

       antivirus_db_t

       - Set files with the antivirus_db_t type, if  you  want	to  treat  the
       files as antivirus database content.

       Paths:
	    /var/clamav(/.*)?,	     /var/amavis(/.*)?,	     /var/lib/clamd.*,
	    /var/lib/amavis(/.*)?,     /var/lib/clamav(/.*)?,	   /var/virus‐
	    mails(/.*)?, /var/opt/f-secure(/.*)?, /var/spool/amavisd(/.*)?

       antivirus_exec_t

       -  Set  files with the antivirus_exec_t type, if you want to transition
       an executable to the antivirus_t domain.

       Paths:
	    /usr/sbin/amavisd.*,      /usr/sbin/clamd,	    /usr/bin/clamscan,
	    /usr/bin/clamdscan,	 /usr/bin/freshclam,  /usr/sbin/clamav-milter,
	    /usr/lib/AntiVir/antivir

       antivirus_home_t

       - Set files with the  antivirus_home_t  type,  if  you  want  to	 store
       antivirus files in the users home directory.

       antivirus_initrc_exec_t

       - Set files with the antivirus_initrc_exec_t type, if you want to tran‐
       sition an executable to the antivirus_initrc_t domain.

       Paths:
	    /etc/rc.d/init.d/clamd.*,		      /etc/rc.d/init.d/amavis,
	    /etc/rc.d/init.d/amavisd-snmp

       antivirus_log_t

       -  Set  files  with  the antivirus_log_t type, if you want to treat the
       data as antivirus log data, usually stored under	 the  /var/log	direc‐
       tory.

       Paths:
	    /var/log/clamd.*,	  /var/log/clamav.*,	 /var/log/freshclam.*,
	    /var/log/amavisd.log.*, /var/log/clamav/freshclam.*

       antivirus_tmp_t

       - Set files with	 the  antivirus_tmp_t  type,  if  you  want  to	 store
       antivirus temporary files in the /tmp directories.

       antivirus_unit_file_t

       -  Set  files with the antivirus_unit_file_t type, if you want to treat
       the files as antivirus unit content.

       antivirus_var_run_t

       - Set files with the antivirus_var_run_t type, if you want to store the
       antivirus files under the /run or /var/run directory.

       Paths:
	    /var/run/clamd.*,	/var/run/clamav.*,  /var/run/amavis(d)?(/.*)?,
	    /var/run/amavis(d)?/clamd.pid, /var/run/amavisd-snmp-subagent.pid

       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 data‐
       base.  You will need to use restorecon to apply the labels.

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.
