The ever-changing landscape of cybersecurity means that with new threats, older technologies give way to more secure and effective means to protect against these threats. One such technology nearing discontinuation is Microsoft NTLM, or NT LAN Manager.
What is NTLM?
Well, Microsoft NTLM is just the set of security protocols created for authentication in a Windows environment. NTLM was crafted to make sure safe login processes over the network, mostly in environments that do not use Active Directory. It operates on the challenge-response concept, which helps a user authenticate without actually sending his or her password across the network. So why is MSFT killing it off?
Why is Microsoft Discontinuing NTLM?
The Transition to Modern Authentication Protocols
As Microsoft phases out NTLM, organizations must transition to modern authentication protocols like Kerberos or Azure AD. This transition involves the important step of assessing what you have in the environment. This includes identifying applications and systems that rely on NTLM and determining the impact of transitioning to newer protocols. This is where Uila uObserve as an observability solution can play a critical role in identifying servers and systems that are running NTLM. It is also recommended that the actual transition should be carried out in stages to minimize disruptions. IT teams must ensure that all systems and applications are compatible with the new protocols and that users are adequately trained on the changes. Post-transition, continuous monitoring using a solution like Uila uObserve is essential to ensure that the new protocols are functioning as expected and that there are no security lapses.
Conclusion
Microsoft NTLM did what it had to, but now it's time to let more secure and efficient authentication methods do their job. By killing NTLM, Microsoft is making an active investment in security for its users. Enterprises should be fast to migrate to modern authentication protocols. Only then will security be at the top spot in the ever-changing cybersecurity environment.
