How to Implement Zero Trust in the Cloud

Key takeaways

Zero trust is a framework built around the belief that a network is always vulnerable to threats, both internal and external. 

• Zero-trust architecture adoption is rapidly growing, with the market worth predicted to reach $84.08 billion in 2030 [1]. 

• Zero trust differs from traditional security systems, which typically fail to consider internal threats, by operating on “least privilege per request.” This minimizes internal and external security risks. 

• You can work in zero trust in roles like cloud security engineer, identity and access engineer, or information security engineer, among others.

What is zero-trust architecture?

This security framework operates based on a belief in constant network vulnerability from external and internal threats. A zero-trust security system operates on what’s called least privilege per request, which ensures an unauthorized user can’t access sensitive data because of the authorization requirements at every step of access. This helps minimize risks. It differs from the traditional “castle-and-moat” security system framework, which considers external threats but considers any internal user safe.

What are the 5 pillars of zero trust?

The US Cybersecurity & Infrastructure Security Agency (CISA) identifies five key areas in its zero trust maturity model: identity, devices, networks, applications and workloads, and data. 

- Identity: The need to verify the digital identity of anyone able to access an organization’s network

- Devices: Organizations should check all devices prior to giving them network access

- Networks: Organizations must segment their networks to minimize access to bad actors

- Applications and workloads: Applications should have limited access to data and systems, and allow only users who must access them with privileges

- Data: Organizations must classify data by importance and value, and encrypt it to prevent unauthorized viewing and access

Understanding the main concepts of the zero-trust approach

Zero trust is quickly becoming the standard for modern security for the public and private sectors, replacing the old model that assumed trust in favor of a strategy that requires more robust authorization. The main concepts of zero trust are as follows:

Data-centric model

Zero-trust security is a data-centric model, meaning it doesn’t base access on a person’s location but rather on the information required for user authentication, such as a password. This approach is helpful because many workers and other users may require remote access to a computer network based in the cloud rather than a network established on computers in an office.

Access control

With zero-trust security, all assets and resources are inaccessible by default. Controlling the access to entry ports and the separate resources themselves implies that if a hostile user manages to get through, the exposure remains limited with minimal fallout. You implement access control by authenticating or verifying a user whenever they ask to access a resource. In preventing access to the entire network in favor of role-based access, you can reduce the risk of a breach and optimize the network’s traffic flow. 

Inspect and log

A crucial part of zero trust is inspecting and logging every user access request and activity. Doing so makes it easier for the system and the IT professionals monitoring it to catch suspicious or repeat access requests that might signal a hacking attempt. Over time, the analysis of these logs leads to more effective security.

What are the benefits and disadvantages of zero-trust policies?

Transitioning from traditional policies to a zero-trust approach requires a commitment to evolving how your business or organization approaches security and access to devices, networks, and data. The primary benefit is more robust security, but zero-trust policies have several other advantages and potential limitations.

Some examples of these pros and cons include:

Pros

• Seamless experiences for employees: Zero-trust authentication methods, such as two-factor authentication, help provide robust security while offering employees a seamless experience.

• Supports hybrid workforce: Zero-trust security systems offer secure remote access to a cloud networking system, which is very effective for a hybrid workforce. This way, resources stay secure no matter where workers log in from.

• Allows for automation: Zero-trust security provides for automation of monitoring, authenticating, and logging of access requests, which saves IT teams time from having to do the same tasks manually.

• Ability to apply consistent policy: Zero-trust security makes it easy to apply authentication policies, increasing the resources' safety consistently.

Cons

• Identity theft could pose a problem: Identity security and preventing someone from maliciously gaining user credentials and accessing sensitive data requires unifying security silos.

• Erosion of control points: Employees often use third-party apps or other SaaS services, which poses a challenge for businesses when ensuring control over every access point or resource, which is vital for zero trust.

• Complicated setup: Zero trust requires companies to invest a lot of time and money into setup, often taking three to five years to integrate zero-trust architecture successfully.

Who uses the zero-trust approach?

Any enterprise using a cloud-based or digital computing network for its daily operations benefits from a zero-trust approach. Both federal and private businesses have used zero trust as part of their security frameworks.

How to implement zero-trust security in the cloud

Data from Grand View Research predicts that the zero-trust architecture market will grow to a worth of $84.08 billion in 2030, up from $39.23 billion in 2025, suggesting accelerating adoption of zero-trust security strategies [1]. Successfully implementing it requires a solid action plan and a few essential steps, including the following:

Prepare

Before committing to a zero-trust framework, it’s essential to consider where your business stands as-is. What does your security look like now? What assets and resources are you trying to protect? Who is leadership, and whose buy-in do you need? What type of budget will you have for a new security system? The answers can help give you an idea about your starting point.

Plan

Next, examine the different workflows your business utilizes. You’ll need to know exactly what resources and access points your business has before you can successfully implement the right kinds of authentication and security applications. Knowing everything that’s part of your computing network also makes tracking and logging activities easier, encouraging transparency.

Assess

Once you have an inventory of everything that needs protection, it’s time to assess any security gaps or weaknesses you might have. What security technology is already in place? Where are there opportunities to implement zero trust? Identifying the weak spots and how you might address them helps make the framework more efficient and secure.

Implement

Once you’ve assessed and identified where to begin, it’s time to implement. Rolling out new applications and security protocols requires cooperation and staff, so be diligent and aware that this new process takes time, but it will be a net positive in the end.

How to implement zero trust: Cybersecurity roles to consider

Zero trust has roots stretching back to the 1990s when it was a largely academic concept. The modern security landscape increasingly demands these types of stringent security policies. It also requires professionals with the skills to help implement cybersecurity strategies. If you’re interested in a career that uses zero trust, you should know that the US Bureau of Labor Statistics anticipates the information security job market will grow by 29 percent in the decade leading up to 2034 [2]. A few of the jobs that you might consider include the following:
