🔐 Zero Trust isn’t simply:

“Trust nobody.”

It’s about continuously evaluating access based on factors such as:

Identity
Device
Location
Application
Risk
Context

Access should be verified—not automatically assumed.

What Zero Trust concept took you the longest to understand?

The big takeaway:

STP doesn’t eliminate redundancy.

It controls redundancy by preventing Layer 2 loops while keeping backup paths available.

That’s why STP is so important in switched networks.

I’m looking to connect with more people in tech. 🤝💻

Whether you’re in IT Support, Networking, Cybersecurity, Cloud, DevOps, or Software Engineering, I’d love to learn from your journey and share what I’m learning along the way.

What area of tech are you in? 👇

[Tremaine McAdams @TreyInTech]

@aformerdriver Yes endpoint security has been big, aswell as least privilege.

[Tremaine McAdams @TreyInTech]

Help Desk is teaching me something I didn’t fully appreciate before:

Every user account, permission, endpoint, and access request is part of an organization’s security posture.

IT support isn’t separate from security.

It’s one of the foundations.

Agree or disagree? 🔐
