Zero Trust is a high-level strategy that assumes that individuals, devices, and services that are attempting to access company resources, even those inside the network, cannot automatically be trusted. To enhance security these users are verified every time they request access, even if they were authenticated earlier.
- Zero trust has become very important as more security breaches happen from inside a network than from the outside.
- Two-factor authentication (2FA) remains the foundational element of a zero-trust security architecture or process.
- Zero trust incorporates adaptive security controls that dynamically adjust access privileges and security measures based on changing risk factors and contextual information. Allowing organizations to adapt their security posture in response to evolving threats and business requirements.
- The seven pillars of zero trust are: User, Device, Network & Environment, Application & Workload, Data, Automation & Orchestration, and Visibility & Analytics.
- Zero trust adoption can offer organizations benefits like protection of sensitive data; support for compliance auditing; a lower breach risk and detection time; clear cut visibility into network traffic; and good control in cloud environments.
- Cisco’s perspective is that for organization to ensure zero trust they must: establish trust, enforce trust-based access, continually verify trust, and respond to change in trust.
- To promote security Zero trust, ensure these users are verified every time they request access, even if they were authenticated earlier.
