Displaying a generic error message without details about the system architecture or software versions is the correct approach because it prevents attackers from gaining insights into the underlying system, which could assist in crafting targeted attacks. Providing excessive details can inadvertently supply attackers with valuable information. Logging the error internally is useful for debugging but does not directly address the concern of exposing details to the user. Redirecting to the home page could create usability concerns and may not address the root issue of sensitive error disclosures. Customizing HTTP response codes is not a sufficient method for obscuring sensitive error information because these codes could still reveal system characteristics.
