What are the two types of sniffing techniques?

• A. Active and passive sniffing
• B. Automated and manual sniffing
• C. Static and dynamic sniffing
• D. Local and remote sniffing

Answer: (A)

The two types of sniffing techniques are active and passive sniffing. Active sniffing involves the attacker actively sending packets to the network to intercept or manipulate data being transmitted. This may include techniques like ARP spoofing, where the attacker sends falsified ARP messages over the network, associating their own MAC address with the IP address of another device, allowing them to capture and manipulate traffic. On the other hand, passive sniffing is a technique where the attacker listens to the traffic on the network without actively injecting or modifying packets. This is typically done on networks where traffic is not encrypted, allowing the attacker to observe data being transmitted. Passive sniffing is often used in environments like a shared Ethernet segment where all devices can see the same data packets on the network. Understanding these two techniques is crucial for ethical hackers, as it helps in assessing how data can be exposed and what strategies can be employed to secure sensitive information during transmission.
