• Choosing encryption methods for stored data
• Reviewing TLS settings for encrypted connections
• Designing password storage and token signatures

Analyze a target's TLS configuration — negotiated protocol version, cipher suite, certificate chain, expiry, and downgrade vectors. Use when: SOC2 auditor flagged your endpoint for "weak TLS" but you don't know which control failed (TSC CC6.7 transmission integrity vs CC6.6 encryption) or which cipher is the problem. Threshold: any negotiated TLSv1.0 or TLSv1.1, OR a cipher with RC4 / 3DES / null / EXPORT, OR a cert with under 30 days to expiry, OR a chain that fails hostname verification. Trigger with: "audit tls", "check ssl config", "weak tls", "analyze tls".

Comprehensive methodology for auditing and exploiting TLS/SSL implementations and misconfigurations across network services and mobile applications. Covers protocol downgrade attacks including POODLE (CVE-2014-3566) against SSLv3 CBC padding, DROWN (CVE-2016-0800) cross-protocol attack leveraging SSLv2 export ciphers to decrypt TLS sessions, and FREAK (CVE-2015-0204) forcing RSA export-grade key exchange.

Configures Amazon CloudFront content delivery across six workflows: when to use CloudFront and how it fits with AWS WAF, Shield, CloudFront Functions, Lambda@Edge, Route 53, and origins (creating a distribution, caching, and Flat Rate Pricing (FRP) versus pay-as-you-go pricing); managing custom-domain TLS certificates (ACM in us-east-1); configuring multi-tenant distributions; protecting origins with origin access control (OAC), VPC origins, and origin mutual TLS (mTLS); securing content with signed URLs and cookies, geographic restrictions, viewer mutual TLS, and edge token validation; and observing traffic with standard and real-time logs. Applicable when the customer wants to put CloudFront in front of content, choose pricing, lock an origin, restrict who can view content, or analyze logs. Not applicable for the Route 53 DNS side of a CloudFront custom domain or failover between distributions (see the route53-cloudfront skill), or for pure-Route 53 DNS work (see the route53 skill).
