Embracing a Zero Trust Security Model

How to protect your people, devices, and data across the enterprise.

The Journey to Zero Trust

Digital transformation, cloud technologies, and the remote workforce have created new cybersecurity challenges for organizations across the globe. The need to defend and respond to security threats has never been more apparent before.

Today’s modern-day organizations require an adaptive and resilient Zero Trust security model to effectively protect people, devices, and data across the enterprise.

Wondering where to start with Zero Trust? Gauge your security maturity to identify gaps in coverage and develop a cohesive strategy.

What is Zero Trust?

Coined by Forrester over 10 years ago, the phrase “Zero Trust” is based on the belief that trust is a vulnerability, and therefore, security must be defined by the strategy, “Never trust, always verify.”

With the rise of mobile technology and cloud migration, an organization’s network perimeter is much harder to define. Data is now continuously transferred between software as a service (SaaS) applications, infrastructure as a service (IaaS), remote users, IoT devices and more, providing multiple entry points for hackers to access sensitive information.

Instead of assuming everything behind the corporate firewall is safe, Zero Trust principles strengthen an organization’s security maturity by eliminating a perimeter-based defense and focusing on strict authentication at each access point. A Zero Trust security model ensures that no device, user, system, or workload is trusted by default, regardless of the location it is operating from.

Zero Trust Principles

Presume all networks are untrusted:

Verify each request as though it originates from an open network.

Apply least privilege access: 

Restrict access based on the minimum permissions required to carry out a task.

Assume breach:

Reduce risk by inspecting and monitoring everything.

A Practical Guide to a Zero Trust Implementation

Forrester’s guide provides a roadmap to help you understand the practical building blocks of a successful Zero Trust implementation. 

Is Zero Trust Right for You? The Barriers and Benefits

Interest in Zero Trust has increased during the COVID-19 pandemic as many organizations have acknowledged their perimeter-based security strategy produces vulnerabilities, especially with a remote workforce. Over the years, applications have been pushed into the cloud, but users unexpectedly being pushed outside the perimeter is a new challenge for many IT and security teams.

On top of these recent obstacles, threat actors are becoming more sophisticated than ever before with their tactics. Along with many others, your organization may be leaning towards a Zero Trust security model to help improve security posture and reduce risk to your business. Depending on your business goals, resources, and legacy systems, you may run into different barriers and benefits while implementing a Zero Trust security model.

Barriers:

Implementing a Zero Trust architecture requires you to unwind legacy infrastructure, workflows, and processes that create new challenges. Depending on the size and complexity of your organization, you may run into barriers such as:

Benefits:

While organizations may face many barriers when implementing a Zero Trust security model, the outcome can lead to many benefits, including:

  • Budget and funding
  • Team buy-in
  • Board-level support
  • Change with vendors
  • Complete and cohesive execution
  • Time investment
  • Resource constraints
  • Improve network traffic visibility
  • Increase control in the cloud environment
  • Prevent threats and mitigate breaches
  • Enhanced compliance reporting
  • Enable adaptability with digital transformation
  • Reduce overall capital expenditure (CAPEX)
  • Streamline operating expenses (OPEX)

Building a Zero Trust Security Model

Implementing a Zero Trust architecture is a complex journey that is a continual process. Every organization’s path to Zero Trust can look different and it’s important to be patient and prioritize your projects and initiatives one step at a time. From small to large companies, expect the process to be a marathon, not a sprint.

Forrester recommends building a security model that requires an end-to-end strategy based on seven elements in the Zero Trust eXtended ecosystem (ZTX):

Data

Classify sensitive information in your data to guide policies and controls on what needs to be protected.

People

Consistently monitor user access and apply least privileged concepts at every level.

Workloads

Establish a cloud governance process and management solution, conduct inventory, and monitor workload configurations.

Devices

Apply network segmentation principles to create microperimeters that isolate IoT devices.

Networks

Reduce attack surface and lateral movement by segmenting boundaries around network assets.

Visibility and Analytics

Invest in the ability to correlate events across disparate domains.

Automation and Orchestration

Implement response protocols and technologies that can prioritize threats, improve workflow, and reduce mean time to respond (MTTR).

Learn About LogRhythm's Journey to a Zero Trust Model

Zero Trust is the next evolution of the industry’s security model. It moves organizations away from large, corporate perimeters with layered-in or bolted-on compensating security controls, to a model comprised of many micro perimeters at each identity type. Charting a strategy is essential to successfully making the transition.

Having been through it ourselves, we know how challenging and yet rewarding the journey to a Zero Trust model can be.

This white paper introduces the concept of a Zero Trust ecosystem and illustrates how we at LogRhythm embarked on our own Zero Trust journey. Read more to discover:
