Security Fundamentals — Question 47
Which provides the highest level of security in a firewall?
Answer options
- A. Stateful inspection
- B. Outbound packet filters
- C. Stateless inspection
- D. Inbound packet filters
Correct answer: A
Explanation
Stateful inspection provides the highest level of security because it monitors the state of active connections and makes decisions based on the context of the traffic. In contrast, stateless inspection and packet filters do not track the state of connections and are less effective at preventing sophisticated attacks.
