9. What is session hijacking in the context of Man-in-the-Middle (MitM) attacks?

a) Session hijacking involves taking control of a user's active session with a web application or service, allowing the attacker to impersonate the user and perform unauthorized actions.

b) Session hijacking involves intercepting and potentially altering the communication between two parties without their knowledge, allowing the attacker to eavesdrop on sensitive information or manipulate the communication.

c) Session hijacking involves flooding a target system with a large volume of traffic or requests, causing it to become overwhelmed and unavailable to legitimate users.

d) Session hijacking involves exploiting vulnerabilities in the encryption protocols used to secure network communication, allowing the attacker to decrypt and access sensitive information transmitted between two parties.
