mTLS & Service Mesh Security FAQs

Question 1

How does this skill help with Istio configurations?

Accepted Answer

It provides patterns for PeerAuthentication modes (Permissive vs. Strict), AuthorizationPolicies for workload isolation, and managing the Istiod control plane for certificate issuance.

Question 2

Does this support Linkerd specifically?

Accepted Answer

Yes, it covers Linkerd-specific automatic mTLS features, identity services, and ServerAuthorization resources for securing mesh traffic without complex YAML.

Question 3

Can I migrate to mTLS without causing service downtime?

Accepted Answer

Yes, the skill outlines a phased migration strategy starting with Permissive mode to observe traffic, followed by testing and gradual namespace-by-namespace enforcement of Strict mode.

Question 4

Why use short-lived certificates in a service mesh?

Accepted Answer

Short-lived certificates (often 24 hours or less) significantly reduce the security risk if a key is compromised and eliminate the operational overhead of managing Certificate Revocation Lists (CRLs).

Question 5

What is the difference between TLS and mTLS?

Accepted Answer

Standard TLS involves the client verifying the server's identity. Mutual TLS (mTLS) requires both the client and the server to present and verify each other's certificates, ensuring two-way authentication.
