This talk provides campus leaders with a strategic overview of Distributed Denial of Service (DDoS) attacks, tailored for CIOs and institutional executives. Unlike previous talks that focused on technical details, this session emphasizes the broader implications and risks associated with DDoS threats. Attendees will gain valuable insights into how these attacks can impact institutional operations and learn best practices for prevention and response. This strategic discussion aims to equip leaders with the knowledge needed to safeguard their campuses from these growing threats.
