Security Enhancement Technology Preventing SDN Link Attacks Through LLDP Integrity Verification

This technology relates to SDN controllers, security enhancement systems in SDN environments, and security enhancement methods in SDN environments. Specifically, it is a security enhancement technology that prevents SDN link attacks through LLDP integrity verification.

Existing technologies needed to address LLDP link fabrication attacks and LLDP flood attacks in SDN environments by verifying the integrity of LLDP packets and monitoring the ports of each switch. To address this, this technology proposes a configuration that includes an SDN controller with a monitoring module, a switch list module, and a detection module.

Accordingly, this technology can improve the security of SDN environments by preventing LLDP link fabrication attacks and LLDP flood attacks. It has value for use in the broadcasting, telecommunications, IT, internet, and software fields.
