Security-Enhanced Linux secures the webalizer processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the webalizer_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 webalizer_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux webalizer policy is very flexible allowing users to setup their webalizer processes in as secure a method as possible.
The following file types are defined for webalizer:
webalizer_etc_t
- Set files with the webalizer_etc_t type, if you want to store webalizer files in the /etc directories.
webalizer_exec_t
- Set files with the webalizer_exec_t type, if you want to transition an executable to the webalizer_t domain.
webalizer_tmp_t
- Set files with the webalizer_tmp_t type, if you want to store webalizer temporary files in the /tmp directories.
webalizer_usage_t
- Set files with the webalizer_usage_t type, if you want to treat the files as webalizer usage data.
webalizer_var_lib_t
- Set files with the webalizer_var_lib_t type, if you want to store the webalizer files under the /var/lib directory.
webalizer_write_t
- Set files with the webalizer_write_t type, if you want to treat the files as webalizer read/write content.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux webalizer policy is very flexible allowing users to setup their webalizer processes in as secure a method as possible.
The following process types are defined for webalizer:
webalizer_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.
The SELinux user type webalizer_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
anon_inodefs_t
