A computing system and related method protect a computer network connection manager's resources from attempted resource attacks by extracting SrcIP and TTL values from received data packet headers. Extracted SrcIP and TTL values are analyzed to determine the probability that a received data packet is malicious. If the probability exceeds a specified threshold, resources are denied, and the packet is dropped. If the specified threshold is not exceeded, resources are allocated to the received data packet. The SrcIP reputation score, TTL value frequency, SrcIP frequency, SrcIP geo-location, and resource occupancy may all be used in computing the probability of a malicious data packet. These factors may be weighted and summed to calculate the probability of a malicious data packet.

A method and system for generating an API schema associated with at least one API Endpoint by inspecting network data traffic. Network data requests that have been successfully served by an application associated with at least one API endpoint are examined, parsed and processed to generate an API schema corresponding to the service associated with the at least one API Endpoint.

A method and system for generating a set of API Endpoints includes receiving network data requests to extract raw URL strings and http Methods therefrom, splitting the URL strings into component groups, and building a component tree. Dynamic components are detected and replaced with a generic designator. The component tree is then collapsed by merging identical branches into a single branch, thereby providing a set of API Endpoints. Detection of dynamic components can include determining that the number of child nodes paired with a parent node is relatively large; detecting that the number of occurrences of a parent node component is relatively high within a predetermined time in comparison to the number of occurrences of corresponding child node components; detecting a relatively high similarity of grandchild node components that share a parent node; and detecting child components having randomly generated character sequences.

A memory management unit responds to an invalidate by class command by identifying a marker for a class of cache entries that the invalidate by class command is meant to invalidate. The memory management unit stores the active marker as a retired marker and then sets the active marker to the next available marker. Thereafter, the memory management sends an acknowledgement signal (e.g., to the operating system) while invalidating the cache entries having the class and the retired marker in the background. By correlating markers with classes of cache entries, the memory management can more quickly respond to class invalidation requests.
