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 daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1
129
133 The SELinux process type denyhosts_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

218 SELinux requires files to have an extended attribute to define the file
219 type.
220 You can see the context of a file using the -Z option to ls
222 Policy governs the access confined processes have to these files.
224 SELinux denyhosts policy is very flexible allowing users to setup their
225 denyhosts processes in as secure a method as possible.
226 STANDARD FILE CONTEXT
228 SELinux defines the file context types for the denyhosts, if you wanted
230 to store files with these types in a diffent paths, you need to execute
231 the semanage command to sepecify alternate labeling and then use
232 restorecon to put the labels on disk.
233 semanage fcontext -a -t denyhosts_var_log_t '/srv/mydenyhosts_con‐
235 tent(/.*)?'
236 restorecon -R -v /srv/mydenyhosts_content
237 Note: SELinux often uses regular expressions to specify labels that
239 match multiple files.
240 The following file types are defined for denyhosts:
242 denyhosts_exec_t
246 - Set files with the denyhosts_exec_t type, if you want to transition
248 an executable to the denyhosts_t domain.
249 denyhosts_initrc_exec_t
253 - Set files with the denyhosts_initrc_exec_t type, if you want to tran‐
255 sition an executable to the denyhosts_initrc_t domain.
256 denyhosts_var_lib_t
260 - Set files with the denyhosts_var_lib_t type, if you want to store the
262 denyhosts files under the /var/lib directory.
263 denyhosts_var_lock_t
267 - Set files with the denyhosts_var_lock_t type, if you want to treat
269 the files as denyhosts var lock data, stored under the /var/lock direc‐
270 tory
271 denyhosts_var_log_t
275 - Set files with the denyhosts_var_log_t type, if you want to treat the
277 data as denyhosts var log data, usually stored under the /var/log
278 directory.
279 Note: File context can be temporarily modified with the chcon command.
283 If you want to permanently change the file context you need to use the
284 semanage fcontext command. This will modify the SELinux labeling data‐
285 base. You will need to use restorecon to apply the labels.
286
289 semanage fcontext can also be used to manipulate default file context
290 mappings.
291 semanage permissive can also be used to manipulate whether or not a
293 process type is permissive.
294 semanage module can also be used to enable/disable/install/remove pol‐
296 icy modules.
297 semanage boolean can also be used to manipulate the booleans
299 system-config-selinux is a GUI tool available to customize SELinux pol‐
302 icy settings.
