Have you Instituted Zero Trust Security?

As technology propels us forward at a rapid pace, the cybersecurity landscape must not only keep up but stay ahead of the curve. Zero Trust security has played a major role in this transformative improvement. Its approach is to continuously verify every connection attempt before granting resource access rather than the traditional perimeter-based security models.

Adopting Zero Trust is a “Top” or “High” priority to 56% of global organizations.

Zero Trust offers significant security advantages, but the transition process does present several potential pitfalls. Running afoul of these can significantly harm a company’s security efforts.

To avoid costly mistakes, let’s examine these common roadblocks and offer guidance on navigating a successful Zero Trust security policy.

What is the zero trust technique?

In ITFIRM.COM’s blog pages, we have likened network cybersecurity to a castle with all its fortifications, but Zero Trust throws out the simple old periphery-based ‘castle and moat’ security model where everyone inside the network perimeter is trusted and only those outside are held to scrutiny.

Not ‘Trust but Verify’ – Verify First, THEN Trust.

When you use Zero Trust, you assume that everyone and everything is a potential threat until proven otherwise. This is true even for users already inside the network. This may sound extreme, but cybersecurity needs to be swift and sure, and Zero Trust enforces a rigorous ‘verify first, access later. approach.

What are the three principles of Zero Trust?

1) Always Explicitly Verify: Authentication doesn't happen once. It's an ongoing, exacting process. Users and devices are constantly re-evaluated for access rights.

2) Use Least Privileged Access: Users only get access to the specific resources they need to do their jobs, no more.

3) Assume the Breach: Zero Trust simply assumes that breaches are inevitable, and that the network has already been compromised. It counters this assumption through Risk Mitigation Through Micro-Segmentation, wherein Your IT Services team will divide the network into smaller segments, limiting the damage if a breach occurs.

Typical Zero Trust Adoption Errors

Zero Trust is not something you can just take out of the box, plug in and walk away. Care must be taken to implement it, but it’s worth it. Here are some missteps you must not take:

Zero Trust is a Strategy, not Just a Product

People who hawk Zero Trust might make it sound like a product they can sell you. Don't be fooled! It is a security philosophy that requires a cultural shift within your organization.

A Zero Trust strategy requires the use of many approaches and tools, include things like multi-factor authentication (MFA) and advanced threat detection and response.

Focus on the Big Picture, not Just on Technical Controls

Your people and processes play as crucial crucial role in Zero Trust as the technology itself. This is a team sport. Your employees will need to be trained on the new security culture and the updated access control policies. The human element is critical in any solid security strategy.

KISS (Keep It Simple, Stupid!)

Do NOT Overcomplicate the Process. For it to work, the steps to Zero Trust must be calculated and measured. – taken one at a time. Do NOT try to tackle everything at once, because that can be overwhelming, and smaller companies may give up. Start with a pilot program focusing on critical areas. Then, gradually expand your Zero Trust deployment bit by bit.

Pay Heed to the User Experience

This is not something you can just throw at your staff – that can create excessive hurdles for legitimate users. Adopting controls like MFA (Multi-Factor Authentication) can backfire if employees aren’t kept in the loop. Find the right balance between security and a smooth user experience. Use change management to help ease the transition process.

Take Inventory

You can’t reliably secure what you don't know exists. Find out what you have and catalogue all your devices, users, and applications before deploying Zero Trust. This helps identify potential access risks. It also provides a roadmap for prioritizing your efforts.

Bear Your Legacy Systems in Mind

You still need to rely on your older security systems while you are implementing Zero Trust, so don’t leave yourself unprotected during the transition. Integrate your legacy systems into your security framework or consider secure migration plans. Forgotten legacy systems can lead to data breaches that impact your entire network.

Beware of Third-Party Access

One of your weakest security points are third-party vendors. Clearly define access controls and check their activity within your network. Set time-limited access as appropriate.

Zero Trust is a Journey

Take your time - no hurry. Don’t be like The White Rabbit in Alice in Wonderland, who prophetically stated, "The hurrier I go, the behinder I get." Building a robust Zero Trust environment takes time, effort, and care.

Stay on track by following these tips:

Establish Realistic Goals: Exercise patience - don't expect overnight success. Define achievable milestones and celebrate progress along the way.

Adopt Continuous Monitoring: Whether you’re adopting Zero Trust, growing a field of corn, or raising a herd of cattle, keep an eye on things. Security threats are constantly evolving, and so must you. Continuously watch your Zero Trust system and adjust your strategies as needed.

Train Your Employees: Empower your employees as active participants in your Zero Trust journey. Regular security awareness training is vital.

Enjoy the Rewards of a Secure Future

By avoiding these common mistakes and adopting a strategic approach, you enable your business to leverage the big advantages of Zero Trust security. Here's what you can expect:

Enhanced Data Protection: Zero Trust minimizes the damage from a potential breach. It does this by limiting access to sensitive data.

Improved User Experience: Streamlining your access control creates a smoother experience for authorized users.

Increased Compliance: Zero Trust aligns with many industry regulations and compliance standards.

Once you decide to take the first step with Zero Trust security, first equip yourself with knowledge, then plan your approach, and above all, avoid these common pitfalls. This will enable you to transform your security posture and build a more resilient business in the face of evolving cyber threats.

A Zero Trust cybersecurity strategy provides for better peace of mind.
