Nozomi Networks has patented a method for verifying network device vulnerabilities using Common Vulnerabilities and Exposures (CVE) entries. The method involves indexing CVE entries, decoding network packets, and matching them with CVE entries to raise alerts. The process includes generating a CVE tree, splitting CPE records, and tokenizing decoded strings for matching.

Method for verifying network device vulnerabilities using cve entries
A recently granted patent (Publication Number: US11930033B2) outlines a method for verifying vulnerabilities of network devices using Common Vulnerabilities and Exposures (CVE) entries. The method involves indexing each CVE entry, decoding network packets related to the network device, and matching the decoded string with the indexed CVE entry to raise an alert when a match is found. The indexing process includes generating a CVE tree, identifying vulnerable configuration fields, and extracting sets of vulnerable conditions. The decoding process involves tokenizing the decoded string into n-grams, while the matching process includes a lookup into the CVE tree based on the operator attribute and CPE records.
Furthermore, the patent details additional aspects of the method, such as identifying main operator attributes and nested sets of vulnerable conditions, as well as specific protocols like the Cisco Discovery Protocol for network packets. The method also specifies the range of n-gram sizes used, the identification of vulnerable configuration fields and operator attributes, and the normalization process for the decoded string before tokenizing. Overall, the method provides a comprehensive approach to verifying vulnerabilities in network devices using CVE entries, enhancing cybersecurity measures for network infrastructure.
