A candidate selection algorithm efficiently matches thousands of vulnerability signatures simultaneously using a small amount of memory. A parsing transition state machine achieves fast protocol parsing. Certain examples provide a computer-implemented method for network intrusion detection. The method includes capturing a data message and invoking a protocol parser to parse the data message. The method also includes matching the parsed data message against a plurality of vulnerability signatures in parallel using a candidate selection algorithm and detecting an unwanted network intrusion based on an outcome of the matching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Matching with a large vulnerability signature ruleset for high performance network defense","description":"Systems, methods, and apparatus are provided for vulnerability signature based Network Intrusion Detection and/or Prevention which achieves high throughput comparable to that of the state-of-the-art r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8522348","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
