  • Patent number: 11736498
    Abstract: A system for stateful detection of cyberattacks includes an endpoint computer and a backend computer system. The endpoint computer monitors for cyberattacks and sends out queries for detected security events. The backend computer system stores observation data that are included in the queries. The backend computer system combines current observation data from a current query, relevant observation data from previous queries, and relevant cybersecurity data. The combined data are evaluated for cyberattacks.
