MONITORING ZERO TRUST

"The only safe computer is the one that's unplugged, locked in a safe, and buried 20 feet under the ground in a secret location... and I'm not even too sure about that one."

​— ​DENNIS HUGES, FBI.

In our age of rampant digital threats, this quote rings true more than ever. But burying computers isn't an option. Instead, we secure them. And Zero Trust is the way to go. Its enforcement, though, relies on real-time visibility into hundreds of user and application identity attributes. These attributes are the eyes and ears of your cybersecurity strategy.

First, consider user identity and credential types. Every user, be it human or programmatic, has a unique identity. Their credentials carry the access keys to your systems. The type of these credentials—whether they belong to a person or a software—matters greatly. It's like the ID card at the entrance of a high-security building, defining who gets in and who doesn't.

Next, look at credential privileges on each device. Not all credentials should have the same access. It's like the key card that grants entry to some doors but not others in an office building. Similarly, in your digital landscape, privileges should be tailored per device, per user. This fine-grained access control is a cornerstone of the Zero Trust model.

Thirdly, consider the normal connections for the credential and device, their behavior patterns. Just like knowing the usual paths of a person helps in spotting any unusual activity, understanding the normal patterns of credentials and devices aids in detecting anomalies. It's like a digital footprint that should follow a predictable trail.

Then, there's the endpoint hardware type and function. Knowing what device is connecting to your network and for what purpose is crucial. It's like knowing if a car or a bike is entering your premises and why. An unfamiliar hardware type or an unexpected function could be a red flag.

Your strategy should also account for geo-location. In the same way, you'd be alert if a person from a distant, unexpected location tries to access your building, be aware if a connection request comes from an unusual geo-location. It could be a sign of a potential security threat.

Firmware versions are like the engine versions in vehicles. Some are up-to-date, reliable, and efficient, while others might be outdated and susceptible to breakdowns. Keeping track of these versions helps you ensure your digital engines are robust and secure.

The same applies to operating system versions and patch levels. Just as a patched-up tire might need more attention than a brand new one, devices running on outdated operating systems or patch levels may pose a risk to your network's security. Regular updates and patching are essential in maintaining a strong security posture.

Then, there's the matter of applications installed on the endpoint. It's like knowing what's inside a car before allowing it inside your premises. A dangerous item could pose a risk. Similarly, a malicious application on a device could be a threat to your network.

Lastly, security or incident detections play a critical role. It's
