Which of the following is NOT a technique used in a MitM attack?Select one:a.Port knockingb.SSL stripingc.ARP spoofingd.Phishinge.DNS spoofing

Breakdown of the Problem

1. Understanding MitM Attacks: A Man-in-the-Middle (MitM) attack occurs when an attacker intercepts the communication between two parties without their knowledge.

2. Identifying Techniques: Review the options provided for techniques commonly used in MitM attacks.

Relevant Concepts

1. Port Knocking: A security measure that involves sending a series of connection attempts to different ports to gain access, not typically used for intercepting communications.

2. SSL Striping: A technique used to downgrade secure HTTPS connections to insecure HTTP, allowing the attacker to intercept and read communications.

3. ARP Spoofing: A method of associating the attacker's MAC address with the IP address of another device, which can redirect traffic through the attacker.

4. Phishing: A social engineering technique used to trick individuals into providing sensitive information; not a traditional MitM attack.

5. DNS Spoofing: A technique to redirect traffic from a legitimate website to a malicious site by corrupting the DNS cache.

Analysis and Detail

1. Port Knocking is primarily a means of securing access rather than intercepting ongoing communications, which makes it distinct from the other options.
2. The other techniques (SSL stripping, ARP spoofing, phishing, DNS spoofing) are all strategies that a MitM attack might employ to gain unauthorized access to or intercept communications.

Verify and Summarize

• Port knocking does contrast with the other techniques mentioned as it does not actively intercept or manipulate communication streams.
• Therefore, it is identified as the method not used in a typical MitM attack.

Final Answer

a. Port knocking is NOT a technique used in a MitM attack.
