Gatekeeper gives you three options for choosing which types of applications you can install on your Mac. There are two types of signatures: those included in applications downloaded from the Mac App Store, and those of developers who have registered with Apple and obtained Developer IDs. Gatekeeper looks for a “signature” in an application this is a sort of certificate that is included in an application, and it tells Mountain Lion where the application came from. GatekeeperĪnother essential security feature in Mountain Lion is Gatekeeper, a technology that prevents certain applications from being installed on a Mac. Threats using these types of elements are theoretically prevented from doing anything outside the boundaries of the web browser. Sandboxing is not only important because of the possibility of a user unwittingly installing a Trojan horse, but also to prevent threats that come through web pages: Java, Flash, QuickTime and others.
Any application you use that creates or edits files can only access files it creates, or files that you expressly import to that application’s space. If you use an iPhone or iPad, you can see this. A set of restrictions prevents the application from accessing files it doesn’t need, and a set of “entitlements” allows the application to access certain files or folders. When an application runs in a sandbox, its rights are limited.

If you are, applications have more rights than if you have a standard user account.) Even if an application doesn’t need to access certain system files, it still has the right to do so. (This depends on whether you are running an administrator’s account or not. Without sandboxing, any application can read and write files almost anywhere on your Mac. In computer security, sandboxing is similar any application you run is in a “sandbox” that prevents it from going beyond certain boundaries and performing actions that it shouldn’t. A traditional sandbox has boundaries that allows kids to play within a certain space. One of Mountain Lion’s marquee security features is called sandboxing.
