Which Burp Suite tool tests the randomness of session tokens?

• A. ID Serve
• B. Sequencer tool
• C. NCollector Studio
• D. httprecon

Answer: (B)

Testing the randomness of session tokens means checking whether those tokens are unpredictable enough to resist guessing or prediction. Burp Suite's Sequencer analyzes token values extracted from server responses and applies statistical checks to assess entropy and detect patterns. If the tokens show high entropy and no repeating or recognizable patterns, they’re considered random and secure against simple guesswork. If there’s any determinism or low entropy, it signals a weakness that could enable session hijacking or fixation. Sequencer is the right tool for this because it’s specifically built to test token randomness, including session IDs and other security tokens. The other options are used for different tasks like service identification or reconnaissance, not for evaluating the randomness of tokens.
