A cybersecurity strategy based on the principle of "never trust, always verify," assuming threats exist everywhere. Rather than relying on a single technology, it implements multiple security controls, including multi-factor authentication, EDR, Zero Trust Network Access, and dark web credential monitoring. In addition, users only have access to the specific parts of the network they need and not more.
A security model that requires strict identity verification for every person and device, inside or outside the network perimeter, trying to access resources on a private network.
A security framework that assumes threats are everywhere and therefore verifies every user and device attempting to access resources, and grants least-privileged access to specific applications rather than to the entire network. A foundational security model within SASE.
A type of threat that exploits an unknown software vulnerability before the user/developer knows about it or has a patch ready, giving defenders no time to fix it. Also known as a 0-day.
