Simplify CISA’s Zero Trust Roadmap with Modern Microsegmentation

[johny899]

Are you feeling like Zero Trust security is too twisted? You’re not alone. Many organizations struggle with the confusion surrounding it. The good news is: modern microsegmentation makes it much easier to follow CISA’s Zero Trust roadmap and keep your network secure.

Why is Microsegmentation Important?​

Many organizations struggle either with implementing microsegmentation or they are simply skeptical due to past experiences. Microsegmentation sounded like a good idea in theory, but when organizations would spend months trying to implement it, it would bring their environment to a standstill. But, besides considering what organizations used to think about microsegmentation, CISA has since indicated given the need for organizations to shift away from the classical perimeter back to a trust-based security model, microsegmentation is a important part of the Zero Trust security model. It helps:

• Prevent lateral movement of threat actors inside of the network
• Contain ransomware incidents, limiting restore scope
• Compliance with security risks and regulations

The Common Problems​

Despite being a valuable tool in the toolbox of security processes, it is not utilized at high levels across teams in the field. Why?

• Derivative to difficulty to implement
• Disruption to normal business activity
• Limitation on older applications
• High cost factor for traditional vendors

CISA indicates to approach microsegmentation in increments, including: finding your most important resources, mapping resource connectivity, writing rules, and introducing protections in intervals. It is also easier to think about this concept in terms of securing one room at a time versus the entire building.

How Modern Microsegmentation Helps​

Modern technology makes microsegmentation much easier for teams to:

• Quickly block attacks
• Quickly stop ransomware
• Always monitor networks without stopping work

This all makes it easier to implement, scale, and manage Zero Trust.

Why You Should Care​

Microsegmentation isn’t a cool buzzword. In today’s world of networks and advanced cyber-attacks, limiting damage fast is crucial. Modern technology makes it possible for all organizations to do this, not just the largest IT teams.

My Perspective​

I have watched many teams use legacy, manual processes - when they are slow, it’s frustrating to get things done. Modern microsegmentation feels like it saves time and alleviates stress. It allows you to get back to real security work, rather than dealing with all the setup complexity.
