Zero Trust Security Framework Explained: What Is It And Do I Need It?
What is Zero Trust and what does it include? How will implementing a Zero Trust strategy strengthen my IT infrastructure security posture? Can Zero Trust be added to my existing systems seamlessly?
If you’re like many small and medium-sized businesses, you may be asking these and other questions when it comes to protecting your network against cyber threats.
A Zero Trust security framework is a cybersecurity model that protects an organization’s sensitive data by relying on the premise that threat actors are lurking all around, both within and outside your network infrastructure.
The rapid rise of cloud migration and the growing trend toward hybrid and remote work models are driving factors in the increasing demand for Zero Trust.
It recognizes that your network perimeter can include on premises data centers, cloud storage and computing, and remote devices and applications.
Zero Trust requires that all users be constantly validated, abandoning the old method of “trust first, verify later.” By upending the traditional implicit trust model, Zero Trust’s system of continual verification is designed to better safeguard modern business environments against cyber threats.
After reading this article, you will have a thorough understanding of what Zero Trust principles are and the steps you need to take to implement this effective security strategy.
What Is A Zero Trust Security Framework?
A Zero Trust approach incorporates many factors since each device or user must be verified at every stage of interaction.
Zero Trust predetermines and regulates communication between users, devices, and applications. It requires that everyone trying to access your network provide more than one method of verification (or multi-factor authentication).
The basic philosophy behind Zero Trust is what’s known as “least privilege access,” or zero trust network access (ZTNA). This security measure simply approves the least amount of access needed for users to do their jobs. It also provides end-to-end encryption over the internet to ensure secure remote access to data on your network.
Following its fundamental principle of “never trust, always verify,” Zero Trust’s demand for continuous authentication means no one and nothing is to be trusted by default.
Zero Trust assumes that breaches can happen both inside and outside your network. By limiting network authorization on a need-to-know basis, Zero Trust restricts movement within your IT network to prevent hackers from gaining access to your sensitive files and applications.
You might be wondering at this point what goes into launching a Zero Trust framework?
While the concept is relatively straightforward, seamlessly weaving it into an established network environment is far from simple.
That’s because it can mean significant changes to your IT infrastructure and logistics and require knowledgeable personnel to handle it.
Here are the main components of a Zero Trust security framework:
- Critical asset identification and verification
- Strong multi-factor authentication of user
- Biometrics
- Device privileges and certification
- Identity and Access Management
- Endpoint security
- Data and email encryption
- Geolocation
- Firmware updates
- Authentication protocol and risk assessment
As you can see, Zero Trust encompasses many different security systems within your network. So, while Zero Trust does offer advanced protection for your IT infrastructure, its complexity also means that it will require more time and cost more to implement than standard measures.
Establishing A Zero Trust Model: 3 Essential Components
Before you can get started in setting up Zero Trust, it is important to have a team in place to begin evaluating your entire IT environment. Undertaking a Zero Trust architecture means having a thorough understanding of your assets and how they function within your IT landscape.
3 steps to launching a Zero Trust Security Framework:
1. Evaluate Your IT Infrastructure
To begin your Zero Trust implementation journey, start by conducting a thorough inventory of your IT environment, including users, devices, data, applications and services. You can then classify and segment these critical assets by roles, device types, services, identity, or group functions.
A systemwide review and audit analysis will help you know your starting point and understand what vital assets you have that need safeguarding.
A Zero Trust Security Model uses real-time visibility to evaluate all access requests. So, you have to identify who your users are, the applications they use, and their methods of access.
2. Establish Your Policies and Procedures
From here, you can set up controls to regulate access to the critical assets you identified, being mindful of your existing protocols as well as any regulatory requirements.
Develop and launch a policy of continuous tracking and monitoring as the basis for your Zero Trust framework. This process should include devising an effective incident response plan to cyber threats to allow time for an appropriate response and to mitigate damage.
A comprehensive Zero Trust system will evaluate your established policies and user behavior in real-time to guard against possible cyberthreats. In this way, Zero Trust acts as a perpetual security system to watch over your organization’s IT infrastructure.
Federal regulations such as NIST 800-171 and CMMC establish robust cybersecurity requirements for companies doing business with the Department of Defense.

The regulations are meant to better safeguard federal contract information (FCI) and controlled unclassified information (CUI) among DoD contractors and subcontractors that handle such sensitive information.
While adopting a Zero Trust security framework is not a requirement, it is a best practice for organizations looking to optimize their security.
3. Create Cybersecurity Buy-in Within Your Organization
Change is never easy, and trying to implement new processes and procedures as part of your overall security initiative will require that everyone within your organization is on board.
Providing employee security awareness training is an essential part of fostering employee buy-in.
The cybersecurity education helps staff to not only be able to identify potential threats, but also to understand how to avoid them altogether. They also learn what to do and who to reach out to in the event of a cyber incident.
