Embodiments provide a security infrastructure that may be configured to run on top of an existing operating system to control what resources can be accessed by an applications and what APIs an application can call. Security decisions are made by taking into account both the current thread's identity and the current thread's call chain context to enable minimal privilege by default. The current thread context is captured and a copy of it is created to be used to perform security checks asynchronously. Every thread in the system has an associated identity. To obtain access to a particular resource, all the callers on the current thread are analyzed to make sure that each caller and thread has access to that resource. Only when each caller and thread has access to that resource is the caller given access to that resource.

Granting least privilege access for computing processes

This disclosure describes techniques of using a centralized rule database to control the abilities of software processes to perform actions with regard to resources provided by a computer. As described herein, each software process executing in a computer executes within a chamber and each resource provided by the computer is associated with a canonical name that uniquely identifies the resource. Furthermore, the computer stores a set of security rules in a centralized rule database. In addition, this disclosure describes techniques of enforcing the rules stored in the centralized rule database.

Centralized enforcement of name-based computer system security rules

Systems and methods of position sensing for a receiver, via employing an ability thereof to receive signals in a broader range than what such receiver is initially tuned for. A frequency skip component can skip channel frequencies such that the spectrum range is scanned without a typical requirement of tuning to all the channels during such scan. Accordingly, the subject innovation enables the entire spectrum of interest to be scanned at a substantially reduced amount of time. Location interpolation for the receiver and time stamping of received signals can be implemented as part of the position sensing.
