Secure EcmaScript (SES)
Secure EcmaScript (SES) is a frozen environment for running EcmaScript
(Javascript) 'strict' mode programs with no ambient authority in their global
scope, and with the addition of a safe two-argument evaluator
(SES.confine(code, endowments)). By freezing everything accessible from the
global scope, it removes programs abilities to interfere with each other, and
thus enables isolated evaluation of arbitrary code.
It runs atop an ES6-compliant platform, enabling safe interaction of mutually-suspicious code, using object-capability -style programming.
See https://github.com/Agoric/Jessie to see how SES fits into the various flavors of confined EcmaScript execution. And visit https://rawgit.com/Agoric/SES/master/demo/ for a demo.
Derived from the Caja project, https://github.com/google/caja/wiki/SES .
Still under development: do not use for production systems yet, there are known security holes that need to be closed.
Incorporates (as a git submodule) the Realms shim from https://github.com/tc39/proposal-realms .
