SES-shim VS JS-Interpreter

I used E in the 90s: http://erights.org/

I haven't kept up with newer systems but I've heard of https://github.com/endojs/endo and just came across http://reports-archive.adm.cs.cmu.edu/anon/home/anon/isr2017... (which says "in the style of the E programming language" -- that's as far as I've read) while looking that up.

WebAssembly was designed to follow the same capability security principles. CHERI too as someone else just brought up.

There are other potential solutions I haven’t explored close enough (like Endo and SES), or completely omitted as they’re based on an imperfect blacklist-based approach to security (like sandboxed WebWorkers). However, the mentioned 4 solutions are the top contenders, at least in my mind.

I don't know why you are being silently downvoted, as I think it is worth talking about the potential of using static analysis to improve things.

One promising approach is Endo[0] which "uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."

Agoric moved forward and Realms gave way to SES

https://github.com/endojs/endo/tree/master/packages/ses

And Endo is a set of tools (being) built around it to make it more practical for particular usecases

Yea you could restrict the app by whitelisting only the network services and folders that it will use and that's pretty valuable though at least on Linux could already easily be achieved otherwise. It's good that Deno makes it easy but let's be honest, most people will just pass -A.

I'd love to see a permissions system on a library basis. It would ask the first time a dependency is added and when a new permission is requested after an update. Javascript doesn't make that easy though by being so dynamic. SES could maybe help: https://github.com/endojs/endo/blob/master/packages/ses/READ...

I was poking around on the internet a bit earlier and I found this project. It looks pretty cool, and I figured perhaps a few of y'all might find it cool too!

I have no idea if it actually sandboxes networking by default. This other project, endo[0], seems to add some of that functionality.

Regardless of the maturity though, it makes me excited to see this type of work getting done now!

(What made me want to research it was this[1] thread from the other day.)

Fortunately the problem could become more tractable if something like SES / Endo takes off:

"Endo protects program integrity both in-process and in distributed systems. SES protects local integrity, defending an application against supply chain attacks: hacks that enter through upgrades to third-party dependencies. Endo does this by encouraging the Principle of Least Authority. ... Endo uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."

Yeah. JavaScript is probably the closest to being there (with things like SES[0], LavaMoat[1], etc.) but we're not quite there yet. It's just shocking that this sort of thing is as seemingly obscure as it is; it's like the whole industry has collectively thrown up their hands and said code execution is unavoidably radioactively dangerous. (While simultaneously using package managers that... well.) But it doesn't have to be!

JS-based JavaScript interpreter — even though it was a more reassuring option for me (especially with some projects already available in this space), a JS interpreter written in JS simply isn’t a performant solution;

See: #242

Each program is written in JavaScript and interpreted by JS-Interpreter. A step() function of JS-Interpreter is applied to each program alternately.

Here you are, its A JS Interpreter written in JS https://github.com/NeilFraser/JS-Interpreter

Haha, both of those cases are killing both the iframe and the UI. I have to get around to using totally different domain on the iframe to really take advantage of the Chrome process isolation. Previously I was using a really nice JS interpreter written in JS[0] before to solve that problem, but it ran 200 times slower than the browser interpreter(!)

I don't care what current level he is he could Learn and use a "proper" already sanetized interpreter like https://github.com/NeilFraser/JS-Interpreter and implement it by a command sending the result back it demends a real level in Javascript but if he really wants to do it he could. But if you rly wanna drag down someone on his level for no reason go on I am not judge on here and btw I don't advertise I just provide info and links to people / servers whitch did it or here a way to do it. If you are rly that dumb or think you are the only one able to think properly here I invite you to get outta here ;) and as always have a great rest of your day :) I don't consider the invite as advertising taking that taking as point that it is a community server on the subject of this subreadit.
