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
       command 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 following:

       /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  per-
       missive 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.
       Disabled by default.

       setsebool -P antivirus_can_scan_system 1

       If  you	want  to  determine  whether  can antivirus programs use JIT compiler, 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. Enabled 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

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/lib/clamav 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/lib/clamav /srv/clamav
       restorecon -R -v /srv/clamav

       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/virusmails(/.*)?,
	    /var/opt/f-secure(/.*)?, /var/spool/amavisd(/.*)?, /var/lib/clamav-unofficial-sigs(/.*)?

       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 transition 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 database.	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 policy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
