Let's remake the Internet

[ShawnJG]

One of the best things about writing software is that you constantly get to make things that didn't exist before. Internet was originally created so scientists could share information almost instantaneously. The Internet has evolved into something most people could not have conceived back then. Now that we know it's capabilities, if we could remake the Internet from the ground up, how would you do it, what would you include? Even with web 2.0 there's a lot of legacy involved if we were completely unshackled from the past to make it in HN's image, how would it look?

I know this is a radical idea, but just imagine making something completely new to compete with the entire Internet! Forget just targeting individual sites or services, what could be awesome enough to change the entire face of online computing? please promote this topic, we are really smart people on the HN message boards and I would really like to get comments from as many people as possible. Not only is it a great thought exercise but who knows what could come out of it in real life. Thank you.

ShawnJG: I share your Interests and have plans on how to redesign the Internet as well. Are you looking for a co-founder? I am. Call/text me on 850-240-1383 (Florida number but I'm local to SV) I'd like to discuss this topic with you off-line. Or email a4c4g4@gmail.com.

and here is the second repost bynextparadigms...

Make it even more decentralized and more P2P based. Eliminate as many points of failure as possible. Use something like the Phantom Protocol for increased freedom and security as well:

I posted this topic super early in the morning and it got pushed down before a lot of people could see it. I did manage to get two really good comments before that happened. I'm going to repost them here including the usernames of the people who posted them.

I would replace the server - I mean, do we really need servers? In short, the internet and networks in general were not designed with security in mind. (I would like to apologize in advance for the lengthy response but I want to make myself clear)

The Client-Server model is the most widely adopted model of networking. As the basis of the internet, it is also most difficult to depose. Even in its most basic form, it precludes security and rejects attempts to secure interacting systems for the following reasons: 1) The server is just that - a slave that serves its masters, the clients. Despite security measures to limit and control client access, the server must at least: a) Listen for client requests - clients must be able to locate, and thus can target servers. b) Attempt to interpret, then determine whether to grant or deny the request - performing redundant (permissions are decided a-priori) and risky work in its own environment. 2) Clients need servers throughout their entire presence on the network, so servers remain open to attack throughout a client’s session. 3) Servers have access to all resources and to other clients’ data during any session with an individual client. 4) Exploiting a server confers the ability to exploit all of its clients and all resources.

The mode of implementation of networks introduces even more insecurities: 1) The system relies on explicit security-related information - such information can be falsified, thus the system cannot support non-repudiation. 2) The system transports clients to any destination they specify - it is up to the destination to defend itself against unwanted guests. 3 )Any client or server on the network can be discovered by any other client or server - the network can be searched systematically to find and exploit vulnerable targets.

In short, the server is and will continue to be a target for hackers. However, if the target (server) was removed, would we have security breaches? Probably not, but more importantly for all users, we would not have an internet as we know it. Therefore, we need a medium that accomplishes both - a hardware element that allows for network communications (but without the insecure handles that make up a server) as well as allowing us to make up the network we now call the internet. Pure fantasy or are we just too engrained with what we have to be able to ‘think outside the box’?

Let’s look at why? There have been admirable strides towards making today’s systems more secure. There is also significant and proactive efforts focused on finding vulnerabilities and developing patches to fix them before they can be exploited. Although security measures exist, none are truly pre-emptive. In my view, everyone is just making variations of the same thing and, more importantly, we’re just ‘barking up the wrong tree’! Current defense strategies follow three common underlying themes: 1) most tend to focus on particular attackers, attacks, or attack methodologies; 2) many aim to defend particular targets or groups of targets; 3) all are confined and subverted by the existing framework for computing and networks. In its entirety and more importantly, current defensive strategies cannot 1) prevent most unknown attacks; 2) make targets unavailable for exploitation, nor 3) compensate for design flaws in the system being defended. Therefore, would it not be more instructive to examine what enables the initiation of attacks? i.e., what are the handles that allow the system to be breached?

As I eluded to above, the interaction between client and server software/systems, on which (often flawed) software is based, presents too many handles for misuse and abuse. Therefore, this argument points to one and only one common denominator - the network is inherently insecure by design, i.e., this is the problem that security people should be addressing, not a new variant-kind-of patch. So, if I could travel back to the 1990’s to design the networks/internet (as you have suggested) and knowing what I know now, what and how would I design it? More importantly, can it be redesigned today? Or should security product developers stay content and conform to the present hardware and software platforms and just develop ‘patches’? Even if software could be made flawless in logic, it may not be feasible to prevent the misuse of software. Don’t forget the human element - that in itself is the weakest ‘link’ in network security.

We are therefore left with redesigning the computer and network environments to allow flawed software (and people) to operate securely and render such software (and people) inoffensive should their flaws (and actions) be targeted (be used) for exploitation. This implies that the network (and elements of the network) be fault-tolerant or, more to the point, secure by design. So, we can have the benefits of a network and the protection from network security into one all encompassing computer-network infrastructure.

My suggestion: It should be conceivable and possible to map and mete out resources to clients/users as they are accepted onto the network. This is the basis of client completion; for each user/client, a host environment is created in which all allowable services and resources are locally available and locally supported. We already pre-determine the "stuff" the user needs/requires to have access to on the server - so why not bypass the server? Since access to and management of these resources is local, there is no need, or means by which, to interact with the server or the network; the client is thus complete - a discrete entity on the network. The containment of this discrete component must be as complete as possible to ensure that there is no "leakage" to other client or server environments if the user exploits any vulnerability in the client.

I can see a distinct and separate internet from the current one and more businesses and services coming out from this model.

OK, I've said enough...hopefully that will spur more discussions on this subject =)
