Which technique can help identify the true source of attacks by tracing back to the origin?

• A. Event Log Analysis
• B. Packet Traceback
• C. Rate limiting
• D. Load Balancing

Answer: (B)

Tracing the path of packets back to their origin is the purpose of packet traceback. This technique helps reveal the true source of an attack by reconstructing the route that malicious packets took through the network, which is especially valuable when the attacker uses spoofed addresses. By collecting trace data from routers or using packet markings, you can infer where the traffic began and follow it back toward its source. Event log analysis focuses on examining records from hosts and applications to detect events, but it doesn’t reliably trace traffic across the network to its true origin. Rate limiting and load balancing are defensive measures to manage or distribute traffic and reduce impact, not methods for locating where an attack originates.
