Abstract: A distributed security system can include instances of a compute engine that can execute either locally in security agents on client devices or as cloud instances in a security network. Event data can be processed by elements of the distributed security system according to centrally-defined ontological definitions and/or configurations. Bounding managers of local security agents can control how much event data is sent to the security network. A storage engine in the security network can store event data received from client devices, can route event data to other elements of the security network, including cloud instances of the compute engine. An experimentation engine of the security network can also at least temporarily adjust other elements of the distributed security system during experiments or tests.

Abstract: Interpolant pattern matching reflects a runtime environment. Any interpolant finite automata (such as a DFA) using a regular expression may be modified with an interpolant string to create an interpolant finite automata (such as an IDFA). The interpolant string incorporates a placeholder that is then modified according to the runtime environment. An environmental variable or a directory path, for example, may be inserted into the placeholder at runtime. An input string may be pattern matched to the IDFA that reflects the runtime environment.
