What Are OSI Layers in Networking? 

The OSI Model has 7 layers, each handling a specific network function. Cyberattacks target these layers differently — knowing them helps improve security. 

Layer 1: Physical Layer Attacks 

This layer includes cables, switches, and hardware. 

Common Attacks: – Cable tapping – Hardware destruction – Signal interference – Unauthorized device acce

Layer 2: Data Link Layer Attacks 

Targets MAC addresses & switching. 

Attacks:  MAC flooding, ARP poisoning, CAM table overflow, Switch spoofing

Layer 3: Network Layer Attacks 

Attacks: – IP spoofing – Route hijacking – ICMP flooding – DoS/DDoS attack

Focused on IP routing & traffic flow.

Layer 4–7 Attacks 

Attacks include: – SYN Flood (Layer 4) – Session hijacking (Layer 5) – SSL stripping (Layer 6) – SQL injection, XSS, CSRF (Layer 7)
