  • Intrusion detection to prevent impersonation attacks in computer networks
    Patent number: 10193907
    Abstract: In an embodiment, a central computer performs a data processing method. The central computer receives telemetry data from intrusion sensors. The central computer stores authentication records in a hosts database. Each authentication record is based on the telemetry data and comprises a thumbprint of a public key certificate and a host identifier of a sender computer. The central computer receives a suspect record that was sent by a first intrusion sensor. The suspect record has a first particular thumbprint of a first particular public key certificate and a first particular host identifier of a suspect sender. From the hosts database, the central computer searches for a matching record having a same host identifier as the first particular host identifier of the suspect record and a same thumbprint as the first particular thumbprint of the suspect record. The central computer generates an intrusion alert when no matching record is found.
