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 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 For example:
18 ps -eZ | grep denyhosts_t
20
24 The denyhosts_t SELinux type can be entered via the denyhosts_exec_t
25 file type.
26 The default entrypoint paths for the denyhosts_t domain are the follow‐
28 ing:
29 /usr/bin/denyhosts.py
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for denyhosts:
43 denyhosts_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type denyhosts_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux denyhosts policy is very flexible allowing users to setup their
146 denyhosts processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the denyhosts, if you wanted
151 to store files with these types in a diffent paths, you need to execute
152 the semanage command to specify alternate labeling and then use re‐
153 storecon to put the labels on disk.
154 semanage fcontext -a -t denyhosts_var_log_t '/srv/mydenyhosts_con‐
156 tent(/.*)?'
157 restorecon -R -v /srv/mydenyhosts_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for denyhosts:
163 denyhosts_exec_t
167 - Set files with the denyhosts_exec_t type, if you want to transition
169 an executable to the denyhosts_t domain.
170 denyhosts_initrc_exec_t
174 - Set files with the denyhosts_initrc_exec_t type, if you want to tran‐
176 sition an executable to the denyhosts_initrc_t domain.
177 denyhosts_var_lib_t
181 - Set files with the denyhosts_var_lib_t type, if you want to store the
183 denyhosts files under the /var/lib directory.
184 denyhosts_var_lock_t
188 - Set files with the denyhosts_var_lock_t type, if you want to treat
190 the files as denyhosts var lock data, stored under the /var/lock direc‐
191 tory
192 denyhosts_var_log_t
196 - Set files with the denyhosts_var_log_t type, if you want to treat the
198 data as denyhosts var log data, usually stored under the /var/log di‐
199 rectory.
200 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
