Episode 89 — On-Path Attacks: what gets exposed and how to reduce it

On-path attacks appear in CloudNetX scenarios as threats to confidentiality and integrity when attackers can observe, intercept, or manipulate traffic between endpoints. This episode defines on-path attacks as situations where an adversary is positioned to read or alter communications, often through compromised network devices, rogue access points, spoofing techniques, or traffic redirection. The first paragraph focuses on what gets exposed: credentials sent in cleartext, session tokens, sensitive data, and the ability to modify responses or redirect users to malicious destinations. It explains how encryption and certificate validation reduce these risks by protecting confidentiality and ensuring that endpoints can verify they are communicating with the intended party. The episode also emphasizes that on-path risk increases in untrusted networks and poorly segmented internal environments, making control placement and secure defaults central to risk reduction.
