You can do that this way:
1. Create the folders and file custom/Extension/modules/Administration/Ext/Administration/admin_opt.php containing something like that:
PHP Code:
$admin_group_header[] = array(
'LBL_SECURITYSETTINGS',
'',
false,
array(
'SecuritySettings' => array(
'SecuritySettings' => array(
$image_path . 'SecuritySettings',
'LBL_SECURITYSETTINGS',
'LBL_SECURITYSETTINGS_DESCRIPTION',
'./index.php?module=SecuritySettings&action=DetailView&record=1',
),
),
),
'LBL_SECURITYSETTINGS_DESCRIPTION',
);
2. Create an extended language for the module Administration and add the new labels into it;
3. Replace the module name SecuritySettings by the one you want to define in the Admin page;
4. Go to Admin -> Repair -> Rebuild Extensions
