Latest Patents

Among his latest innovations is a patent for a **System and method for utilizing DHCP relay to police DHCP address assignment in ransomware protected network**. This advanced technique aims to mitigate the lateral movement of ransomware within a VLAN. By setting a security appliance as the default gateway for intra-LAN communication, the DHCP responses are overwritten to enhance security. The system can detect message traffic from compromised endpoints, identifying ransomware attributes and attempts to bypass the security measures. Furthermore, it enables the quarantine of compromised devices and polices DHCP address assignments to ensure accuracy and correctness.

Another significant patent focuses on **Troubleshooting multi-layered networks using datapath analysis**. This invention implements a recursive routing mechanism to identify packet-forwarding errors within an IP network that comprises several network-connected devices. By receiving indications of potential errors, a software-defined network device can inject a test packet and determine whether it successfully reaches its intended destination. This capability allows for effective diagnosis and resolution of routing errors, thus maintaining the integrity of the network.
