How to test for MITM attacks and strengthen network security
Key Takeaways
- MITM attacks intercept network communications by impersonating trusted networks or services, allowing attackers to steal credentials and sensitive data.
- Common MITM techniques, including ARP spoofing, DNS spoofing, rogue Wi-Fi, and session hijacking, can be simulated with penetration-testing tools to identify and fix security weaknesses.
- The most effective defense against credential theft is certificate-based authentication (PKI with 802.1X/EAP-TLS), supported by layered security controls such as MFA, network segmentation and regular security testing.
