14. How does a firewall's intrusion detection system (IDS) differ from an intrusion prevention system (IPS)?

IDS monitors and alerts, while IPS monitors and actively prevents

IDS and IPS are the same

IDS prevents, while IPS alerts

IDS and IPS only monitor incoming traffic

15. What is the significance of deep packet inspection (DPI) in firewall security, and how does it contribute to threat detection?

DPI focuses only on the size of data packets.

DPI involves analyzing the content of data packets, enabling detailed inspection and enhanced threat detection.

DPI is outdated.

Firewalls do not support deep packet inspection.

16. Which firewall feature allows or denies traffic based on the application being used?

Packet filtering

Proxy

Deep packet inspection

Stateful inspection

17. What is a benefit of using a firewall's stateful inspection feature?

To block all network traffic

To filter spam emails

To monitor and allow traffic based on the state of active connections

To enhance internet speed

18. Explain the role of anomaly-based intrusion detection in firewall security and its effectiveness against evolving threats.

Anomaly-based intrusion detection relies on predefined signatures to detect threats.

Anomaly-based intrusion detection identifies deviations from established baselines and is effective against evolving threats.

Anomaly-based intrusion detection is obsolete.

Anomaly-based intrusion detection only works for known threats.

19. How can firewalls contribute to a defense-in-depth security strategy, and why is this approach crucial in modern cybersecurity?

Firewalls are the sole defense layer in a defense-in-depth strategy.

Defense-in-depth involves deploying multiple layers of security, and firewalls play a crucial role by adding depth to the protection.

Defense-in-depth is an outdated approach.

Firewalls are not effective in a defense-in-depth strategy.

20. Which term refers to a security mechanism that monitors and manages network traffic based on predetermined security rules?

Firewall

Intrusion Prevention System

Anti-virus

Router

21. Explain the role of a honeypot in firewall security and how it can be used to detect and analyze potential threats.

A honeypot is a security vulnerability in firewalls.

A honeypot is a decoy system designed to attract and detect unauthorized access or attacks, providing valuable insights for threat analysis.

Honeypots are only used for offensive security.

Firewalls cannot incorporate honeypots.

22. What is the primary purpose of a firewall's access control list (ACL)?

To slow down internet speed

To block all network traffic

To define what is allowed or denied

To monitor network traffic

Packet filtering

Proxy

Deep packet inspection

Stateful inspection

33. How does a stateless firewall differ from a stateful firewall, and what are the advantages of each approach?

Stateless firewalls keep track of the state of active connections, while stateful firewalls do not.

Stateless firewalls inspect individual packets, while stateful firewalls examine the context of the traffic.

Stateful firewalls are faster but less secure, while stateless firewalls provide more robust protection.
