This has +implications throughout the game design. + +For instance, to avoid a hack from making invisible players visible, it is +up to the servers not to transmit update information for invisible players +to the clients. This means that invisible players can not make 3d-positional +noises as this would give an exploitable piece of information. + +The front end servers clearly have to be robust too which means that all +incoming data from the clients is treated with caution - packets containing +invalid data are simply ignored. + + +In a nutshell - we assume that servers are trustworthy and that clients are +not. + + +Daniel. + +-----Original Message----- +From: <A HREF="mailto:nel-admin@nevrax.org">nel-admin@nevrax.org</A> [mailto:<A HREF="mailto:nel-admin@nevrax.org">nel-admin@nevrax.org</A>]On Behalf Of +Vincent Caron +Sent: Sunday, December 16, 2001 7:13 PM +To: <A HREF="mailto:nel@nevrax.org">nel@nevrax.org</A> +Subject: Re: [Nel] open source MMORPG and hacks/cheats question +(probablyoff topic) + + +There's a bit more than the 'security through obscurity' debate in this +question.
