Playing in the sandbox
The second category of change is more recent, and it really changes the game. The buzzword is “sandbox”, and it needs a lot of clarification because it is used all over the place in different ways. Roughly the idea is that something can do what it wants within a limited area and cannot really interact with anything outside of that sandbox. It is a safe place to play.
Increased browser sandboxing affects 1Password in two very big ways, and these are because of two different kinds of sandboxing relevant to us.
Sandboxing the browser
The first sandbox that matters for us is that browsers are becoming increasingly restrictive in what bits of your system they can interact with. The way that 1Password interacts with Safari 5.0 and earlier is profoundly different than the way that 1Password is allowed to interact with Safari 5.1 and above. Prior to Safari 5.1, there were “hooks” in Safari that allowed external applications to communicate with Safari. But in Chrome, from its inception, and in Safari from version 5.1 that kind of communication isn’t allowed. This is a major security enhancement; it limits the damage that a browser exploit can do. A successful browser exploit now can only interact with data and processes that are within the browsers’ sandboxes.
