Publication number: 20260342856Abstract: Techniques for determining, by a network security device, a security policy for a data packet with an unknown fingerprint using protocol-aware edit distance, are described. The network security device intercepts a data packet from a source and determines a fingerprint of the source from the data packet. The network security device compares the fingerprint to a plurality of fingerprints in a fingerprint database and determines whether the fingerprint corresponds to an individual fingerprint of the plurality of fingerprints. Based at least in part on determining that the fingerprint does not correspond to an individual fingerprint of the plurality of fingerprints, the network security device determine a protocol-aware edit distance is within a predetermined threshold protocol-aware edit distance of an individual fingerprint of the plurality of fingerprints and applies a security policy associated with the individual fingerprint to the data packet.Type: ApplicationFiled: April 29, 2025Publication date: October 29, 2026Inventors: David Arthur McGrew, Blake Harrell Anderson, Andrew Chi, Adam Burke Weller

Publication number: 20260322587Abstract: Devices and methods relate to managing encrypted communication protocols for network security. A network device may include a security logic. The security logic may receive a domain name system (DNS) response including a first Encrypted Client Hello (ECH) configuration key. Based on receiving the DNS response including the first ECH configuration key, the security logic may replace the first ECH configuration key in the DNS response with a second ECH configuration key. A decryption corresponding to the second ECH configuration key may be supported at the network device. The security logic may transmit the DNS response with the second ECH configuration key. By providing the second ECH configuration key that is known to the security logic to a client device, the security logic gains visibility into one or more encrypted portions of an ECH message from the client device that follows the DNS response.Type: ApplicationFiled: April 14, 2025Publication date: October 15, 2026Inventors: Apoorv Raj, Vikash Ranjan, David Arthur McGrew, Blake Harrell Anderson, Andrew Chi, Durairaj Murugasamy, Shabham Kumar Singh Rajput

Publication number: 20250293992Abstract: Techniques and mechanisms for identifying unmanaged cloud resources with endpoint and network logs and attributing the identified cloud resources to an entity of an enterprise that owns the cloud resources. The process collects data from sources, e.g., endpoint and network logs, with respect to traffic in a computer network and based at least in part on the data, extracts relationships related to the traffic. The process applies rules to the relationships to extract destinations in the computer network that provide cloud resources in a cloud environment, wherein the cloud resources are owned by an enterprise. One or more users or business entities of the enterprise are identified as accessing the cloud resources.Type: ApplicationFiled: February 19, 2025Publication date: September 18, 2025Inventors: Blake Harrell Anderson, Andrew Chi, David Arthur McGrew, Saran Singh Ahluwalia

Patent number: 7379531Abstract: A system uses a digital photographic camera attached to a radiation therapy device to create an overlay of radiation beam information comprising data identifying treated patient anatomical region data and supporting determination of cumulative radiation treatment information from multiple treatment overlays. A system records a treatment beam landing area on the anatomical body surface of a patient for use in radiation or other therapy. The system includes an input processor for receiving data representing an image of the surface of a portion of the anatomy of a patient. A data processor provides beam landing position data relative to the image by calculating a position of a treatment beam landing area relative to the image using received input data indicating projection characteristics of a treatment beam used in treating the portion of the anatomy of the patient. A storage processor stores the beam landing position data in a record associated with the patient.Type: GrantFiled: March 29, 2006Date of Patent: May 27, 2008Assignee: Siemens Medical Solutions Health Services CorporationInventors: Matthew Paul Esham, Loretta A.
