6 denyhosts_selinux - Security Enhanced Linux Policy for the denyhosts
7 processes
8
10 Security-Enhanced Linux secures the denyhosts processes via flexible
11 mandatory access control.
12
13 The denyhosts processes execute with the denyhosts_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 denyhosts_t
20
21
22
24 The denyhosts_t SELinux type can be entered via the denyhosts_exec_t
25 file type.
26
27 The default entrypoint paths for the denyhosts_t domain are the follow‐
28 ing:
29
30 /usr/bin/denyhosts.py
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 denyhosts policy is very flexible allowing users to setup their deny‐
40 hosts processes in as secure a method as possible.
41
42 The following process types are defined for denyhosts:
43
44 denyhosts_t
45
46 Note: semanage permissive -a denyhosts_t can be used to make the
47 process type denyhosts_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. deny‐
54 hosts policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run denyhosts with the tightest access
56 possible.
57

59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
83 The SELinux process type denyhosts_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149
150 You can see the context of a file using the -Z option to ls
151
152 Policy governs the access confined processes have to these files.
153 SELinux denyhosts policy is very flexible allowing users to setup their
154 denyhosts processes in as secure a method as possible.
155
156 STANDARD FILE CONTEXT
157
158 SELinux defines the file context types for the denyhosts, if you wanted
159 to store files with these types in a different paths, you need to exe‐
160 cute the semanage command to specify alternate labeling and then use
161 restorecon to put the labels on disk.
162
163 semanage fcontext -a -t denyhosts_exec_t '/srv/denyhosts/content(/.*)?'
164 restorecon -R -v /srv/mydenyhosts_content
165
166 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168
169 The following file types are defined for denyhosts:
170
171
172
173 denyhosts_exec_t
174
175 - Set files with the denyhosts_exec_t type, if you want to transition
176 an executable to the denyhosts_t domain.
177
178
179
180 denyhosts_initrc_exec_t
181
182 - Set files with the denyhosts_initrc_exec_t type, if you want to tran‐
183 sition an executable to the denyhosts_initrc_t domain.
184
185
186
187 denyhosts_var_lib_t
188
189 - Set files with the denyhosts_var_lib_t type, if you want to store the
190 denyhosts files under the /var/lib directory.
191
192
193
194 denyhosts_var_lock_t
195
196 - Set files with the denyhosts_var_lock_t type, if you want to treat
197 the files as denyhosts var lock data, stored under the /var/lock direc‐
198 tory
199
200
201
202 denyhosts_var_log_t
203
204 - Set files with the denyhosts_var_log_t type, if you want to treat the
205 data as denyhosts var log data, usually stored under the /var/log di‐
206 rectory.
207
208
209
210 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
215
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219
220 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222
223 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225
226 semanage boolean can also be used to manipulate the booleans
227
228
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
