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
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
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
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
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
60
61
62 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
66 setsebool -P antivirus_use_jit 1
67
68
69
70 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
74 setsebool -P authlogin_nsswitch_use_ldap 1
75
76
77
78 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
81 setsebool -P fips_mode 1
82
83
84
85 If you want to allow confined applications to run with kerberos, you
86 must turn on the kerberos_enabled boolean. Enabled by default.
87
88 setsebool -P kerberos_enabled 1
89
90
91
92 If you want to allow system to run with NIS, you must turn on the
93 nis_enabled boolean. Disabled by default.
94
95 setsebool -P nis_enabled 1
96
97
98
99 If you want to allow confined applications to use nscd shared memory,
100 you must turn on the nscd_use_shm boolean. Disabled by default.
101
102 setsebool -P nscd_use_shm 1
103
104
105
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
111 setsebool -P authlogin_nsswitch_use_ldap 1
112
113
114 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
117 setsebool -P kerberos_enabled 1
118
119
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
214 You can see the context of a file using the -Z option to ls
215
216 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
220 EQUIVALENCE DIRECTORIES
221
222
223 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
229 semanage fcontext -a -e /var/lib/clamav /srv/clamav
230 restorecon -R -v /srv/clamav
231
232 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
238 semanage fcontext -a -e /var/run/amavis(d)? /srv/amavis(d)?
239 restorecon -R -v /srv/amavis(d)?
240
241 STANDARD FILE CONTEXT
242
243 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
248 semanage fcontext -a -t antivirus_tmp_t '/srv/myantivirus_con‐
249 tent(/.*)?'
250 restorecon -R -v /srv/myantivirus_content
251
252 Note: SELinux often uses regular expressions to specify labels that
253 match multiple files.
254
255 The following file types are defined for antivirus:
256
257
258
259 antivirus_conf_t
260
261 - 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
265
266 Paths:
267 /etc/amavis(d)?.conf, /etc/amavisd(/.*)?
268

281
282
283 antivirus_exec_t
284
285 - Set files with the antivirus_exec_t type, if you want to transition
286 an executable to the antivirus_t domain.
287
288
289 Paths:
290 /usr/sbin/amavisd.*, /usr/sbin/amavi, /usr/sbin/clamd,
291 /usr/bin/clamscan, /usr/bin/clamdscan, /usr/bin/freshclam,

293
294
295 antivirus_home_t

299
300
301
302 antivirus_initrc_exec_t
303
304 - Set files with the antivirus_initrc_exec_t type, if you want to tran‐
305 sition an executable to the antivirus_initrc_t domain.

311
312
313 antivirus_log_t
314

316 data as antivirus log data, usually stored under the /var/log direc‐
317 tory.
318
319
320 Paths:
321 /var/log/clamd.*, /var/log/clamav.*, /var/log/freshclam.*,
322 /var/log/amavisd.log.*, /var/log/clamav/freshclam.*
323
324
325 antivirus_tmp_t
326
327 - Set files with the antivirus_tmp_t type, if you want to store
328 antivirus temporary files in the /tmp directories.
329
330
331
332 antivirus_unit_file_t

348
349
350 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
355
357 semanage fcontext can also be used to manipulate default file context
358 mappings.
359
360 semanage permissive can also be used to manipulate whether or not a
361 process type is permissive.
362
363 semanage module can also be used to enable/disable/install/remove pol‐
364 icy modules.
365
366 semanage boolean can also be used to manipulate the booleans
367
368
369 system-config-selinux is a GUI tool available to customize SELinux pol‐
370 icy settings.
