Every layer of the OSI model is a potential target for cybercriminals — from physical tampering to application-level exploits like SQL injection. Understanding these risks and applying the right defensive measures is key to building a strong security posture.

Check this ultimate OSI Layers vs Cyber Attacks breakdown

The OSI Model is the backbone of how networks communicate – but each layer can be a target for cyberattacks. Here’s how hackers strike & how to defend:

1-Application Layer

🔴 Attacks: SQL Injection, Cross-site Scripting (XSS), Remote Code Execution (RCE)

🟢 Defense: Regular patching, input validation, Web Application Firewall (WAF).

2-Presentation Layer

🔴 Attacks: DAT format manipulation, code injection, serialization attacks

🟢 Defense: Validate inputs, secure serialization libraries, prevent code injection.

3-Session Layer

🔴Attacks: Session hijacking, token-based attacks, sidjacking

🟢 Defense: Randomize session IDs, enforce secure logout, secure tokens.

4-Transport Layer

🔴Attacks: SYN Flood, TCP Session Hijacking, UDP Flood

🟢 Defense: Firewall monitoring, mitigate SYN floods, secure data exchange.

5- Network Layer

🔴Attacks: IP Spoofing, ICMP Flood, DoS Attacks

🟢 Defense: IDS/IPS, firewall filtering, anti-spoofing router configs.

6-Data Link Layer

🔴Attacks: MAC Spoofing, ARP Spoofing, VLAN Hopping

🟢 Defense: Port security, ARP spoofing detection, VLAN protocols.

7-Physical Layer

🔴Attacks: Eavesdropping, cable tapping, power disruption, tampering

🟢 Defense: CCTV, secure cabling, access control, monitoring.
