GIAC Certified Enterprise Defender (GCED) — Question 7

If a Cisco router is configured with the "service config" configuration statement, which of the following tools could be used by an attacker to apply a new router configuration?

Answer options

• A. TFTPD
• B. Hydra
• C. Ettercap
• D. Yersinia

Correct answer: A

Explanation

The correct answer is A, TFTPD, as it is a Trivial File Transfer Protocol daemon that can be used to transfer configuration files to the router. The other options, Hydra, Ettercap, and Yersinia, are tools focused on different types of attacks and do not specifically serve the purpose of applying configurations to routers.
