NAME

6       antivirus_selinux  -  Security  Enhanced Linux Policy for the antivirus
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the antivirus  processes  via  flexible
11       mandatory access control.
12
13       The  antivirus processes execute with the antivirus_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep antivirus_t
20
21
22

ENTRYPOINTS

24       The  antivirus_t  SELinux  type can be entered via the antivirus_exec_t
25       file type.
26
27       The default entrypoint paths for the antivirus_t domain are the follow‐
28       ing:
29
30       /usr/sbin/amavisd.*,  /usr/sbin/amavi,  /usr/sbin/clamd, /usr/bin/clam‐
31       scan, /usr/bin/clamdscan, /usr/bin/freshclam,  /usr/sbin/clamav-milter,
32       /usr/lib/AntiVir/antivir
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       antivirus  policy  is  very  flexible  allowing  users  to  setup their
42       antivirus processes in as secure a method as possible.
43
44       The following process types are defined for antivirus:
45
46       antivirus_t
47
48       Note: semanage permissive -a  antivirus_t  can  be  used  to  make  the
49       process  type  antivirus_t  permissive. SELinux does not deny access to
50       permissive process types, but the AVC (SELinux  denials)  messages  are
51       still generated.
52
53

BOOLEANS

55       SELinux   policy  is  customizable  based  on  least  access  required.
56       antivirus policy is extremely flexible and has  several  booleans  that
57       allow  you to manipulate the policy and run antivirus with the tightest
58       access possible.
59

FILE CONTEXTS

293       SELinux requires files to have an extended attribute to define the file
294       type.
295
296       You can see the context of a file using the -Z option to ls
297
298       Policy governs the access  confined  processes  have  to  these  files.
299       SELinux antivirus policy is very flexible allowing users to setup their
300       antivirus processes in as secure a method as possible.
301
302       EQUIVALENCE DIRECTORIES
303
304
305       antivirus policy stores data with multiple different file context types
306       under  the  /var/lib/clamav  directory.  If you would like to store the
307       data in a different directory you can use the semanage command to  cre‐
308       ate an equivalence mapping.  If you wanted to store this data under the
309       /srv dirctory you would execute the following command:
310
311       semanage fcontext -a -e /var/lib/clamav /srv/clamav
312       restorecon -R -v /srv/clamav
313
314       antivirus policy stores data with multiple different file context types
315       under  the  /var/run/amavis(d)?  directory.  If you would like to store
316       the data in a different directory you can use the semanage  command  to
317       create  an equivalence mapping.  If you wanted to store this data under
318       the /srv dirctory you would execute the following command:
319
320       semanage fcontext -a -e /var/run/amavis(d)? /srv/amavis(d)?
321       restorecon -R -v /srv/amavis(d)?
322
323       STANDARD FILE CONTEXT
324
325       SELinux defines the file context types for the antivirus, if you wanted
326       to store files with these types in a diffent paths, you need to execute
327       the semanage command  to  sepecify  alternate  labeling  and  then  use
328       restorecon to put the labels on disk.
329
330       semanage  fcontext  -a  -t  antivirus_var_run_t  '/srv/myantivirus_con‐
331       tent(/.*)?'
332       restorecon -R -v /srv/myantivirus_content
333
334       Note: SELinux often uses regular expressions  to  specify  labels  that
335       match multiple files.
336
337       The following file types are defined for antivirus:
338
339
340
341       antivirus_conf_t
342
343       -  Set  files  with the antivirus_conf_t type, if you want to treat the
344       files as antivirus configuration data, usually stored  under  the  /etc
345       directory.
346
347
348       Paths:
349            /etc/amavis(d)?.conf, /etc/amavisd(/.*)?

351
352       antivirus_db_t
353
354       -  Set  files  with  the  antivirus_db_t type, if you want to treat the

363
364
365       antivirus_exec_t

375
376
377       antivirus_home_t
378
379       - Set files with the  antivirus_home_t  type,  if  you  want  to  store
380       antivirus files in the users home directory.
381
382
383
384       antivirus_initrc_exec_t
385
386       - Set files with the antivirus_initrc_exec_t type, if you want to tran‐
387       sition an executable to the antivirus_initrc_t domain.
388
389
390       Paths:
391            /etc/rc.d/init.d/clamd.*,                 /etc/rc.d/init.d/amavis,

396
397       -  Set  files  with  the antivirus_log_t type, if you want to treat the
398       data as antivirus log data, usually stored under  the  /var/log  direc‐
399       tory.
400
401
402       Paths:
403            /var/log/clamd.*,     /var/log/clamav.*,     /var/log/freshclam.*,
404            /var/log/amavisd.log.*, /var/log/clamav/freshclam.*
405
406
407       antivirus_tmp_t
408

410       antivirus temporary files in the /tmp directories.

413
414       antivirus_unit_file_t
415

429            /var/run/amavis(d)?/clamd.pid, /var/run/amavisd-snmp-subagent.pid
430
431
432       Note: File context can be temporarily modified with the chcon  command.
433       If  you want to permanently change the file context you need to use the
434       semanage fcontext command.  This will modify the SELinux labeling data‐
435       base.  You will need to use restorecon to apply the labels.
436
437

COMMANDS

439       semanage  fcontext  can also be used to manipulate default file context
440       mappings.
441
442       semanage permissive can also be used to manipulate  whether  or  not  a
443       process type is permissive.
444
445       semanage  module can also be used to enable/disable/install/remove pol‐
446       icy modules.
447
448       semanage boolean can also be used to manipulate the booleans
449
450
451       system-config-selinux is a GUI tool available to customize SELinux pol‐
452       icy settings.
