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.

124 SELinux requires files to have an extended attribute to define the file
125 type.
126 You can see the context of a file using the -Z option to ls
128 Policy governs the access confined processes have to these files.
130 SELinux denyhosts policy is very flexible allowing users to setup their
131 denyhosts processes in as secure a method as possible.
132 STANDARD FILE CONTEXT
134 SELinux defines the file context types for the denyhosts, if you wanted
136 to store files with these types in a diffent paths, you need to execute
137 the semanage command to sepecify alternate labeling and then use
138 restorecon to put the labels on disk.
139 semanage fcontext -a -t denyhosts_var_log_t '/srv/mydenyhosts_con‐
141 tent(/.*)?'
142 restorecon -R -v /srv/mydenyhosts_content
143 Note: SELinux often uses regular expressions to specify labels that
145 match multiple files.
146 The following file types are defined for denyhosts:
148 denyhosts_exec_t
152 - Set files with the denyhosts_exec_t type, if you want to transition
154 an executable to the denyhosts_t domain.
155 denyhosts_initrc_exec_t
159 - Set files with the denyhosts_initrc_exec_t type, if you want to tran‐
161 sition an executable to the denyhosts_initrc_t domain.
162 denyhosts_var_lib_t
166 - Set files with the denyhosts_var_lib_t type, if you want to store the
168 denyhosts files under the /var/lib directory.
169 denyhosts_var_lock_t
173 - Set files with the denyhosts_var_lock_t type, if you want to treat
175 the files as denyhosts var lock data, stored under the /var/lock direc‐
176 tory
177 denyhosts_var_log_t
181 - Set files with the denyhosts_var_log_t type, if you want to treat the
183 data as denyhosts var log data, usually stored under the /var/log
184 directory.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
