WHAT IS ZERO TRUST?

Cybersecurity is constantly changing; your business is like a castle under siege from hackers who use a variety of tactics to gain access to your information. It’s been compared to an ongoing?Game of Thrones?scenario with barbarians continually at the gates. But what if instead of just not trusting those outside your castle, you also decided to not trust those inside your castle? What is Zero Trust??

While this also sounds like a?Game of Thrones?scenario, the analogy ends there. Zero Trust in cybersecurity promotes the idea of not trusting any user or device by default, regardless of their location or network environment. Unlike traditional security models that assume trust once a user or device gains access to a network, zero trust assumes that no user or device should be inherently trusted. The core principle of zero trust is?“never trust, always verify.”?

“This isn’t about not trusting your employees,” says MacguyverTech CEO Steve (Mac) McKeon. “It’s about not trusting any?devices that have access to your data. We need to be vigilant about making sure devices are what they appear to be and the people using them are who they appear to be, and we need to check it every single time.”?

This means that internal and external networks and devices are viewed as equal risks, and require strict access controls and continuous monitoring. An example of this is requiring that every user uses multi-factor authentication (MFA) to access a network every time they log in.??

Other practices implemented in Zero Trust include:?

Least Privilege:?Implementing a policy of granting users the minimum access permissions required to perform their tasks minimizes the damage if their credentials are compromised.?

Network Segmentation:?Dividing a business’s network into segments helps isolate and control access to sensitive resources. If a company’s cyber defenses are breached, this helps contain the breach and limit lateral movement.?

Persistent Vulnerability Assessment:?Just because a network is secure today doesn’t mean that it will be secure tomorrow, next week or next month. Real-time monitoring and analysis of user and network behavior are essential to detect anomalies and potential security threats.??

Data protection:?Encryption and data-centric security measures are employed to protect sensitive data, both at rest and in transit.?

These practices and others are part of a growing list used to establish Zero Trust architecture for your business network. As hackers keep finding new ways to compromise data, Zero Trust is becoming more appealing as the best way to keep your data safe. Because unlike?Game of Thrones,?it’s highly unlikely that a bad actor is going to actually tell you that you shouldn’t trust them.?
