Zero Trust Security: Ensuring You Are the Only One Logging In

Nov 02, 2025  Jortty

Zero Trust is a network security strategy. Its philosophy is that no other device or person, inside or outside an organization’s network, is granted access to IT workloads or systems unless they are considered necessary. Thus, it implies zero trust.

The real foundation of the core principles of Zero Trust includes:

• Verify Explicitly: Using something other than the “trust but verify” methods as the principle here aims towards authenticating and authorizing the data available, like the location, identity, workload, data, and others.

• Least Privilege Access: Access gets limited to what is important at the right time with enough access preventing any lateral movement or unauthorized access to the different parts of the network.

• Assume Breach: Operating under the circumstances of possible data breaches, Zero Trust focuses on detection, responses, and instant recovery to reduce any impact on security breaches and their affected radius. Here, you can also get help from reliable tech solutions.

At Jortty, we will now help you learn the best steps to implement this model as a proactive measure to reduce cyber threats.

Implementing Zero Trust

It is a five-step process that is derived from zero-trust methods for empowering individuals.

Switch from Threat Surface to Protect Surface

The conventional concept of the threat surface turns out to be less related to modern IT space. Since the environment is extremely dynamic and created with several elements outside the company’s control, it becomes impossible to address the entire threat surface. Here, it would help if you aimed onto “protect surface” as the highly essential assets of your company that need to get defended:

• Business-critical, private, or sensitive data
• Mission-critical applications
• Software services required for business operations
• Other valuable assets

Map Transaction Flows

Know how to identify the flow of traffic in your network and related networks. You can even use tech help for it. Define the traffic flows needed for business operations, as these should be protected as the other flows are mitigated or blocked out.

Architect a Zero Trust Network

There is no such model as a ZTN or zero-trust network. Your ZTN should be built around safeguarding the surfaces that are considered transaction flows. Always establish a mechanism for enforcing micro-segmentation and using it to create micro-perimeters around important assets, enforce access control, and allow monitoring across different communication layers.

Create a Zero Trust Policy

Once you have ZTN in place, try defining your zero-trust policies. Use the 5 Ws method to ensure that the policy answers the questions about network traffic, those who are allowed to access the resources through what application, when they are allowed access, their location or the address of the assets, and why or for which purpose they need access to it and how.

Monitor and Maintain the Network

Try reviewing the logs regularly to identify anomalies lurking within the traffic, both across the network and at the application level. This will give you key insights into the evolving networks and their policies.

Carrying out these critical steps for your important assets is a lot, and from there, you can eventually extend to additional assets and networks to expand your zero-trust protection.
