FloRa: Flow Table Low-Rate Overflow Reconnaissance and Detection in SDN
August 2024 • Ankur Mudgal, Abhishek Verma, Munesh Singh, Kshira Sagar Sahoo, Erik Elmroth, Monowar Bhuyan
Software Defined Networking (SDN) has evolved to revolutionize next-generation networks, offering programmability for on-the-fly service provisioning, primarily supported by the OpenFlow (OF) protocol. The limited storage capacity of Ternary Content Addressable Memory (TCAM) for storing flow tables in OF switches introduces vulnerabilities, notably the Low-Rate Flow Table Overflow (LOFT) attacks. LOFT exploits the flow table's storage capacity by occupying a substantial amount of space with malicious flow, leading…
