denyhosts_selinux(8)denyhosts SELinux Policy documentationdenyhosts_selinux(8)NAMEdenyhosts_selinux - Security Enhanced Linux Policy for the denyhosts
processes
DESCRIPTION
Security-Enhanced Linux secures the denyhosts processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the deny‐
hosts_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
denyhosts_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the denyhosts_t, you
must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux denyhosts policy is very flexible allowing users to setup their
denyhosts processes in as secure a method as possible.
The following file types are defined for denyhosts:
denyhosts_exec_t
- Set files with the denyhosts_exec_t type, if you want to transition
an executable to the denyhosts_t domain.
denyhosts_initrc_exec_t
- Set files with the denyhosts_initrc_exec_t type, if you want to tran‐
sition an executable to the denyhosts_initrc_t domain.
denyhosts_var_lib_t
- Set files with the denyhosts_var_lib_t type, if you want to store the
denyhosts files under the /var/lib directory.
denyhosts_var_lock_t
- Set files with the denyhosts_var_lock_t type, if you want to treat
the files as denyhosts var lock data, stored under the /var/lock direc‐
tory
denyhosts_var_log_t
- Set files with the denyhosts_var_log_t type, if you want to treat the
data as denyhosts var log data, usually stored under the /var/log
directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
denyhosts policy is very flexible allowing users to setup their deny‐
hosts processes in as secure a method as possible.
The following process types are defined for denyhosts:
denyhosts_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
