一覽

Zero Trust is a security framework where every access request is authenticated, authorized, and encrypted regardless of source. No implicit trust based on network perimeter; every user, device, and service is verified. Used by security architects, DevOps engineers, and infrastructure teams. Salary band $110K–$220K depending on role and experience. Takes 5–6 months to reach competency. Adjacent to network security, identity management, encryption, and compliance.

什麼是 Zero Trust Architecture Design

Zero Trust is a security framework that eliminates implicit trust and requires verification of every access request. Rather than trusting a user or device because they're on the corporate network, Zero Trust verifies identity (who are you?), device posture (is your device secure?), and context (where are you accessing from?) for every access. Access is granted only if all factors check out, and communication between services is encrypted and mutually authenticated. Zero Trust spans identity and access management (IAM), network segmentation, encryption, logging, and continuous monitoring. It's implemented through technologies like multi-factor authentication, mutual TLS (mTLS), API gateways, service meshes, and secrets management.

❓ 常見問題

What is Zero Trust and how does it differ from traditional perimeter security?
Traditional security trusts everything inside the corporate network and blocks external access. Zero Trust assumes no implicit trust; every access (internal or external) must be authenticated, authorized, and encrypted. This is essential as workforces become distributed and cloud-native.
What are the core pillars of Zero Trust architecture?
NIST defines Zero Trust across identity verification, device posture, application authentication, network segmentation, encryption, and monitoring. Together they create defense-in-depth; if one layer is breached, others still protect.
How do I implement Zero Trust in a legacy on-premises infrastructure?
Start with identity: require multi-factor authentication, establish a central identity provider (Okta, Azure AD). Then add encryption (TLS everywhere), network segmentation (microsegmentation), and logging. This is a multi-year journey; prioritize critical systems first.
What is mTLS and why is it critical for Zero Trust?
mTLS (mutual TLS) requires both client and server to authenticate to each other using certificates. This ensures only authorized services communicate. In Kubernetes, service meshes (Istio, Linkerd) implement mTLS automatically between pods.
How do I balance Zero Trust security with user experience and performance?
Automation is key: automate MFA (passwordless via FIDO2), cache authentication decisions (avoid auth latency), and use fast encryption (hardware acceleration). Transparent security (invisible to users) is the goal. User friction should be minimized.
