Cybersecurity for Counties: Navigate the Principles of Zero Trust Architecture

Never trust, always verify. This is the foundation of the zero trust model, and is key to safeguarding critical systems and data in an increasingly digital world.

The persistent and evolving nature of cyberattacks has driven many organizations around the globe to adopt more effective cybersecurity strategies. Data shows that 81% of organizations have adopted or are in progress of adopting zero trust architecture, and have reported a 68% insider threat reduction. 

For counties, having a strong framework to ensure sensitive records and public services stay protected is imperative, and zero trust is becoming a sought-after option to fulfill that goal. Our team specializes in technological solutions for the public sector, enabling county agencies to protect their systems with the latest technology and best practices. We understand the challenges that can come with legacy systems and embracing modern technology, and our team is equipped to tailor specific service offerings to each client based on their needs.

What is Zero Trust Architecture?

It is not uncommon for users who gain access to a network to remain trusted and to always be able to easily log back in. This trust can be exploited by cyber attackers and systems can become compromised much easier, especially from an inside threat. With zero trust, verification will always be required, no matter which user wishes to access the system. 

Zero trust architecture, or ZTA, operates on the concept that any attempt at access could be coming from an attacker. Even if the user or device is within the network perimeter, verification will still be required, and the model will continue to validate users, devices, and connections before granting access to any additional resources. 

When it comes to effective cybersecurity, it is beneficial to embrace the phrase, “it’s better to be safe than sorry.” Zero trust ensures that no access attempt goes unverified.

Principles of ZTA & Their Benefit in County Operations

Least Privilege

This concept, “least privilege,” is a concept utilized by ZTA to grant minimum access privileges in order to minimize any potential damage should a breach occur. Users are given access only to the information and resources that are necessary to perform their job duties. This helps minimize insider threats and mitigates any sensitive county information getting into the wrong hands. Counties are responsible for critical systems that house critical data and power necessary services, so only allowing users to access what they need will help safeguard these assets. 

Never Trust, Always Verify

As stated previously, ZTA requires verification for every user and device that wishes to access a network. Identity, device health, and location are typical pieces of data that will need to be verified before accessing sensitive information and resources. This is another factor that ensures the effectiveness of safeguarding critical data in county networks. 

Micro-Segmentation

With ZTA, networks are segmented into smaller, isolated zones to prevent lateral movement should a breach occur. If one part of a network becomes compromised, micro-segmentation seals off just the one zone in order to contain the threat and prevent it from reaching other parts of the network. Within county systems, there are many different elements that can become the target of a cyber attack, and attackers may attempt to gain access through one part of the system. ZTA ensures that even if an incident occurs, it will remain isolated to one small area.

Continuous Monitoring 

ZTA uses real-time monitoring to detect any threats and address them in an efficient manner. Any unusual login patterns or other suspicious activity will be reported immediately, ensuring county data and resources are kept safe and secure. With many different tasks and projects occurring at the county level, this type of technology is beneficial in enabling continuous monitoring to detect potential threats.

Zero trust architecture is an effective framework that works with traditional cybersecurity methods to ensure systems remain uncompromised. Cyberattacks are becoming increasingly sophisticated with the rise of advanced technologies such as artificial intelligence, and even strong firewalls may not be able to hold up against them. 

By requiring continuous authentication and limiting lateral movement, counties are able to strengthen their digital defense strategy in order to safeguard vital records and services. 

“Zero Trust is not a technology; it’s a security philosophy that rewires how we think about access.”
