Zero-trust security is the new buzzword in the cybersecurity world. You’ve probably heard of it but don’t know what it means, or perhaps you have a vague sense but are waiting to learn more. Here’s all you need to know about zero trust security and why it’s important for your business:
What is zero trust security?
What is zero trust security? Zero-trust security is a way of thinking about security that is based on the premise that everyone and everything in your environment is untrustworthy. This can mean something like:
- With zero trust, you assume an external user attempting to access your network will be malicious. In other words, you don’t take it for granted that they’re trying to help you or do their job well.
- Zero-trust assumes an attacker has already infiltrated your network before detection occurs, so there’s no need to spend time doing perimeter security (like firewalls). Instead, focus on protecting sensitive resources in your environment and preventing unauthorized access by any means necessary—even if it means blocking traffic entirely!
What are the benefits of zero trust security?
Zero trust security provides a number of benefits, including:
- Increased Productivity and Efficiency. With a zero-trust environment, employees are able to access the resources they need to get their jobs done without having to jump through hoops. This helps increase employee productivity and efficiency, leading to better business outcomes.
- Reduced Costs. Zero trust security also helps reduce costs by eliminating the need for complex permissions schemes (which can be very expensive) while still providing full control over access privileges across all devices used by employees in your organization.
How does zero trust work?
Zero trust is a security model that assumes that all users are untrusted and establishes access to systems and data based on user identity and the context of their request. Zero trust is not a silver bullet, but it can be used as a practical approach to protecting your organization’s information assets. Micro Focus experts say, “As hackers are growing more sophisticated, security also needs to adapt and improve.”
How does zero trust work? The principle behind zero trust is that there is no such thing as a trusted network. You can only partially control what happens on your network because you might not know where or how things are being used, what devices people have connected to your systems, or even who those people are. This means that you need to focus on identity management—the ability to identify who someone is—and then ensure appropriate access controls for each person’s role within the organization.
The four fundamentals of zero trust security
Zero trust security is based on four fundamentals:
- Identity – Each person’s unique identity can be authenticated and authorized.
- Location – A person’s location is known, and access to data depends on the user’s location.
- Behavior – Users are authorized based on their behavior, also known as “who they are,” rather than on how they got there (what device they used).
- Device – Devices use authentication information from a separate source so that you don’t have to rely on an insecure device-based approach (like passwords).
Now that they’ve covered zero trust security, have a look at why you need it. According to Gartner research, by 2022, 60% of all cyberattacks will target zero-trust networks. So if you don’t implement zero trust now, you’ll be more vulnerable.
