6 antivirus_selinux - Security Enhanced Linux Policy for the antivirus
7 processes
8
10 Security-Enhanced Linux secures the antivirus processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep antivirus_t
20
24 The antivirus_t SELinux type can be entered via the antivirus_exec_t
25 file type.
26 The default entrypoint paths for the antivirus_t domain are the follow‐
28 ing:
29 /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
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 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 The following process types are defined for antivirus:
45 antivirus_t
47 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
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 If you want to determine whether antivirus programs can use JIT com‐
63 piler, you must turn on the antivirus_use_jit boolean. Disabled by
64 default.
65 setsebool -P antivirus_use_jit 1
67 If you want to allow users to resolve user passwd entries directly from
71 ldap rather then using a sssd server, you must turn on the authlo‐
72 gin_nsswitch_use_ldap boolean. Disabled by default.
73 setsebool -P authlogin_nsswitch_use_ldap 1
75 If you want to allow all domains to execute in fips_mode, you must turn
79 on the fips_mode boolean. Enabled by default.
80 setsebool -P fips_mode 1
82 If you want to allow confined applications to run with kerberos, you
86 must turn on the kerberos_enabled boolean. Enabled by default.
87 setsebool -P kerberos_enabled 1
89 If you want to allow system to run with NIS, you must turn on the
93 nis_enabled boolean. Disabled by default.
94 setsebool -P nis_enabled 1
96 If you want to allow confined applications to use nscd shared memory,
100 you must turn on the nscd_use_shm boolean. Enabled by default.
101 setsebool -P nscd_use_shm 1
103
107 If you want to allow users to resolve user passwd entries directly from
108 ldap rather then using a sssd server for the antivirus_t, you must turn
109 on the authlogin_nsswitch_use_ldap boolean.
110 setsebool -P authlogin_nsswitch_use_ldap 1
112 If you want to allow confined applications to run with kerberos for the
115 antivirus_t, you must turn on the kerberos_enabled boolean.
116 setsebool -P kerberos_enabled 1
118
121 The SELinux process type antivirus_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.

211 SELinux requires files to have an extended attribute to define the file
212 type.
213 You can see the context of a file using the -Z option to ls
215 Policy governs the access confined processes have to these files.
217 SELinux antivirus policy is very flexible allowing users to setup their
218 antivirus processes in as secure a method as possible.
219 EQUIVALENCE DIRECTORIES
221 antivirus policy stores data with multiple different file context types
224 under the /var/lib/clamav directory. If you would like to store the
225 data in a different directory you can use the semanage command to cre‐
226 ate an equivalence mapping. If you wanted to store this data under the
227 /srv dirctory you would execute the following command:
228 semanage fcontext -a -e /var/lib/clamav /srv/clamav
230 restorecon -R -v /srv/clamav
231 antivirus policy stores data with multiple different file context types
233 under the /var/run/amavis(d)? directory. If you would like to store
234 the data in a different directory you can use the semanage command to
235 create an equivalence mapping. If you wanted to store this data under
236 the /srv dirctory you would execute the following command:
237 semanage fcontext -a -e /var/run/amavis(d)? /srv/amavis(d)?
239 restorecon -R -v /srv/amavis(d)?
240 STANDARD FILE CONTEXT
242 SELinux defines the file context types for the antivirus, if you wanted
244 to store files with these types in a diffent paths, you need to execute
245 the semanage command to sepecify alternate labeling and then use
246 restorecon to put the labels on disk.
247 semanage fcontext -a -t antivirus_tmp_t '/srv/myantivirus_con‐
249 tent(/.*)?'
250 restorecon -R -v /srv/myantivirus_content
251 Note: SELinux often uses regular expressions to specify labels that
253 match multiple files.
254 The following file types are defined for antivirus:
256 antivirus_conf_t
260 - Set files with the antivirus_conf_t type, if you want to treat the
262 files as antivirus configuration data, usually stored under the /etc
263 directory.
264 Paths:
267 /etc/amavis(d)?.conf, /etc/amavisd(/.*)?
268 antivirus_db_t
271 - Set files with the antivirus_db_t type, if you want to treat the
273 files as antivirus database content.
274 Paths:
277 /var/amavis(/.*)?, /var/clamav(/.*)?, /var/lib/clamd.*,
278 /var/lib/amavis(/.*)?, /var/lib/clamav(/.*)?, /var/virus‐
279 mails(/.*)?, /var/opt/f-secure(/.*)?, /var/spool/amavisd(/.*)?,
280 /var/lib/clamav-unofficial-sigs(/.*)?
281 antivirus_exec_t
284 - Set files with the antivirus_exec_t type, if you want to transition
286 an executable to the antivirus_t domain.
287 Paths:
290 /usr/sbin/amavisd.*, /usr/sbin/amavi, /usr/sbin/clamd,
291 /usr/bin/clamscan, /usr/bin/clamdscan, /usr/bin/freshclam,
292 /usr/sbin/clamav-milter, /usr/lib/AntiVir/antivir
293 antivirus_home_t
296 - Set files with the antivirus_home_t type, if you want to store
298 antivirus files in the users home directory.
299 antivirus_initrc_exec_t
303 - Set files with the antivirus_initrc_exec_t type, if you want to tran‐
305 sition an executable to the antivirus_initrc_t domain.
306 Paths:
309 /etc/rc.d/init.d/clamd.*, /etc/rc.d/init.d/amavis,
310 /etc/rc.d/init.d/amavisd-snmp
311 antivirus_log_t
314 - Set files with the antivirus_log_t type, if you want to treat the
316 data as antivirus log data, usually stored under the /var/log direc‐
317 tory.
318 Paths:
321 /var/log/clamd.*, /var/log/clamav.*, /var/log/freshclam.*,
322 /var/log/amavisd.log.*, /var/log/clamav/freshclam.*
323 antivirus_tmp_t
326 - Set files with the antivirus_tmp_t type, if you want to store
328 antivirus temporary files in the /tmp directories.
329 antivirus_unit_file_t
333 - Set files with the antivirus_unit_file_t type, if you want to treat
335 the files as antivirus unit content.
336 antivirus_var_run_t
340 - Set files with the antivirus_var_run_t type, if you want to store the
342 antivirus files under the /run or /var/run directory.
343 Paths:
346 /var/run/clamd.*, /var/run/clamav.*, /var/run/amavis(d)?(/.*)?,
347 /var/run/amavis(d)?/clamd.pid, /var/run/amavisd-snmp-subagent.pid
348 Note: File context can be temporarily modified with the chcon command.
351 If you want to permanently change the file context you need to use the
352 semanage fcontext command. This will modify the SELinux labeling data‐
353 base. You will need to use restorecon to apply the labels.
354
357 semanage fcontext can also be used to manipulate default file context
358 mappings.
359 semanage permissive can also be used to manipulate whether or not a
361 process type is permissive.
362 semanage module can also be used to enable/disable/install/remove pol‐
364 icy modules.
365 semanage boolean can also be used to manipulate the booleans
367 system-config-selinux is a GUI tool available to customize SELinux pol‐
370 icy settings.
