AWS Security & Compliance
Writes the FactualMinds guides on AWS security and compliance: identity, threat detection, data protection, and audit readiness.
On Jul 27, 2026, AWS launched the Security Hub MCP App preview—8 read-only tools that bring exposure findings, attack paths, and remediation guidance into Claude Desktop at no additional cost for Security Hub customers.
After Cognito multi-Region replication (June 2026), a B2B API platform (~18k RPS peak) cut auth-related 5xx during a regional drill from 4.2% → 0.1% — but a missing WAF rate rule still let a scraper burn $1.8k in a weekend.
A 280-user SaaS ops team cut Client VPN connection-hours ~62% after moving 34 HTTPS apps to Verified Access — Site-to-Site on TGW stayed for the colo; full-tunnel Client VPN had been burning ~$1.1k/mo in idle connection fees.
After the April 2026 S3 default that blocks SSE-C on new buckets (and on existing buckets in accounts with zero SSE-C objects), a SaaS media platform (~2.4 PB, 418 buckets) found 11 legacy upload paths still sending customer-key headers — all failing 403 until migrated to SSE-KMS.
Shield Advanced is $3,000/mo per org plus DTO fees — for a consumer marketplace (~180M req/mo CloudFront), cost protection credited $41k in scaling charges after a 38-minute L7 event when WAF rate rules were pre-configured.
On a defense-subcontract SaaS (~$42k/mo AWS, CUI in scope), choosing GovCloud (US) over commercial US-East cut inherited-control review from 11 weeks to 4 — after mapping 47 customer-responsibility controls in the SSP inheritance worksheet.
Most remote-access RFPs still default to full Windows desktops — but 60%+ of contractor work is browser-only. WorkSpaces Secure Browser isolates SaaS in AWS; WorkSpaces Applications (formerly AppStream 2.0) streams fat clients without a desktop. A composite regulated services firm cut 3 legacy VDI vendors to 2 OU-scoped patterns and reduced unmanaged-endpoint incidents from ~9/quarter to ~2 after splitting browser vs app streaming.
Prowler finds AWS misconfigurations. This guide covers who remediates findings, IaC fix patterns, Security Hub workflows, and when to bring in AWS security consulting.
Production checklist for Prowler and AWS Security Hub — multi-account setup, scheduled scans, finding workflows, and remediation patterns on AWS.
On June 15, 2026 AWS made Console Private Access work without internet — VPC endpoints route 100% of browser traffic. First-party benchmark: 161 interface endpoints and ~$263/mo for a 12-service 3-AZ pilot in us-east-1.
Security Hub detects control failures. It is not the compliance pipeline — and treating it as one is why teams still scramble for evidence at audit time. The four jobs are distinct: AWS Config detects drift, conformance packs deploy rules org-wide as immutable bundles, SSM Automation remediates the safe class, and evidence accrues via conformance-pack exports plus Security Hub control status (Audit Manager only if you onboarded before it closed to new customers on 30 April 2026). Here is the tool-per-job matrix, a conformance pack with auto-remediation, and the auto-remediation gotcha to design around.
Two 2025 shifts rewrite the IR playbook: GuardDuty Extended Threat Detection now emits a single critical attack-sequence finding instead of a pile of high findings, and AWS Security Incident Response moved to metered pricing (free first 10,000 findings/month, then $0.000676 each) on November 21, 2025. The lesson is to page humans on the top 1% of correlated criticals, isolate instead of terminate, and let auto-triage absorb the rest. Here are the runbooks.
