👉 Catch computing, also known as catch-and-replay, is a method used in network security and data integrity verification where packets of data are captured from a network traffic flow, stored in a buffer, and then replayed back to the original sender or receiver at a later time for analysis. This technique is often employed to detect and analyze malicious activities, such as intrusions or data exfiltration, by comparing the captured packets against known attack signatures or behaviors. Catch-and-replay attacks are particularly insidious because they can bypass traditional network monitoring tools and evade detection by appearing as legitimate traffic. By replaying these captured packets, attackers can manipulate network flows, steal sensitive information, or disrupt services, making catch computing a critical tool for enhancing network security and forensic analysis.
