Still Using These Legacy Protocols? You Could Be Putting Your Network At Risk

Legacy protocols like SMBv1, NTLMv1, and LLMNR persist despite their security risks. Attackers know it and frequently exploit these outdated protocols. If you’ve encountered NT AUTHORITY\ANONYMOUS LOGON in your logs, that can be a sign that legacy authentication protocols like NTLM or SMB are still active in your environment.

Disabling legacy authentication methods and network protocols is a crucial step in hardening your server environments.

In this guide, you’ll learn:

The top five legacy protocols putting your system at risk and how to harden them.
How attacks like NTLM relay, WannaCry, NotPetya, and NTLM Relay Attacks exploit legacy protocols to breach systems.
Manual server hardening, demystified, and how to integrate legacy protocol controls and the tradeoffs of doing it by hand.
Automating legacy protocol hardening using tools to streamline enforcement and reduce misconfiguration risk
