Hubs Are Best for Us, But Everyone Is Using Switches

This lecture explains the network topology impact on sniffing, comparing hubs and switches. You’ll understand why hubs allow easy traffic capture, and why switched networks complicate sniffing efforts. You'll also learn about techniques used to bypass switch limitations.

Key topics:

• Hub vs switch behavior at Layer 2

• Broadcast domains and packet visibility

• Why switched networks limit passive sniffing

• Techniques like MAC flooding and ARP spoofing

• Realistic sniffing conditions in modern networks
