AWS Platform Security
Fixed-scope, evidence-backed AWS implementations for security, governance, and regulated environments.
Scope depends on your account model (single, org, multi-org) and target compliance framework. Confirmed in the execution plan before changes.
Engagement Outputs
Secure AWS foundations - IAM, networking, logging, monitoring, and Well-Architected security baselines.
AWS Security Baseline
Foundational security controls for AWS accounts. GuardDuty, Security Hub, CloudTrail, and Config implemented with correct scoping, retention, and aggregation.
Why it matters: Most AWS accounts have these services enabled but misconfigured. Correct baselines prevent blind spots in detection, logging, and alerting.
Deliverables
- Terraform modules for baseline services
- GuardDuty enablement (org/account scope)
- Security Hub enablement with standards selection
- CloudTrail multi-region logging with central S3 destination
- AWS Config baseline (recorders, delivery, core rules)
- Alerting and notifications (SNS and routing targets)
- Evidence pack: before/after exports, Terraform plan/apply logs, validation outputs
Security Hub Hardening & Findings Triage
Turn findings into fixes. Reduce noise, normalize standards, and route actionable issues to owners with evidence and tracking.
Why it matters: Untuned Security Hub generates hundreds of findings. Without normalization and routing, critical issues get buried in noise.
Deliverables
- Standards tuning (CIS, AWS Foundational)
- Suppression rules with documented rationale
- Finding normalization and severity mapping
- Routing to SNS/Slack/Jira (as applicable)
- Remediation backlog with ownership and priority
- Posture snapshot report (weekly cadence available)
- Evidence pack: suppression config, routing config, backlog export, posture snapshot
IAM Security & Least Privilege
Reduce blast radius by removing over-privileged access. Policy analysis, role consolidation, permission boundaries, and controlled cross-account access.
Why it matters: Over-privileged IAM roles are the most common path to lateral movement. Least privilege limits what a compromised credential can reach.
Deliverables
- IAM policy audit and access review
- Least-privilege role designs
- Permission boundaries as code
- Cross-account role architecture (Org-ready)
- IAM Access Analyzer enablement and review
- Policy validation gates in CI/CD
- Evidence pack: IAM policy diffs, Access Analyzer outputs, validation results
Multi-Account Governance
Consistent security controls across AWS Organizations. SCP guardrails, cross-account roles, centralized logging, and aggregated security visibility.
Why it matters: Without org-level guardrails, each account drifts independently. SCPs and centralized logging enforce consistency at scale.
Prereqs: AWS Organizations access, target OU structure, and account inventory.
Deliverables
- Organizations OU structure and account placement plan
- Service Control Policies (SCPs) as code
- Cross-account IAM roles and trust model
- Centralized logging account architecture
- Security Hub aggregation and delegated admin setup
- New-account baseline automation
- Evidence pack: SCP exports, org structure, aggregation verification, baseline automation logs
Regulatory assurance for AWS: ISO 27001, SOC 2, GDPR, NIS2. Evidence automation and audit-ready outputs mapped to controls.
Compliance Evidence Automation
Continuous evidence capture with cryptographic integrity. Tamper-evident storage, indexed retrieval, and framework mapping.
Why it matters: Manual evidence collection breaks at audit time. Automated capture with integrity proof means evidence is always current and verifiable.
Deliverables
- Event-driven change detection (EventBridge)
- Evidence capture functions (Lambda)
- Tamper-evident storage (S3 Object Lock where applicable)
- Integrity proof (hashing and KMS signing)
- Evidence index (DynamoDB) and retrieval queries
- Framework mapping (ISO 27001/SOC 2/GDPR/NIS2)
- Evidence pack: sample evidence bundle, integrity proofs, mapping output
Compliance Readiness
Implement technical controls for a target framework. Gap assessment, control deployment in AWS, and evidence mapping to audit-ready outputs.
Why it matters: Compliance without technical controls is paperwork. Controls deployed in AWS with mapped evidence give auditors what they actually verify.
Deliverables
- Gap assessment against target framework
- Control-to-AWS service mapping
- Control implementation plan and execution
- Incident response runbooks and automation
- Evidence documentation and mappings
- Reporting templates and audit support pack
- Evidence pack: gap report, mappings, implementation diffs, runbooks
Security embedded in CI/CD - policy-as-code, drift detection, and controlled remediation.
Policy-as-Code Implementation
Shift-left enforcement for infrastructure changes. OPA/Rego policies integrated into CI/CD to block non-compliant plans before deploy.
Why it matters: Catching violations after deployment means rollback. Catching them in CI prevents most non-compliant changes from reaching production.
Deliverables
- OPA/Rego policy library aligned to baseline
- Terraform validation hooks
- CI/CD integration (GitHub Actions/GitLab CI)
- Policy test suite
- Violation reporting format and evidence
- Policy documentation and handover
- Evidence pack: pipeline runs, policy test results, violation examples
Drift Detection & Remediation
Continuous enforcement of your baseline. Detect drift, raise findings, and remediate only with explicit approval or scoped auto-remediation rules.
Why it matters: Console changes bypass IaC. Without drift detection, your Terraform state diverges from reality and your baseline erodes silently.
Deliverables
- AWS Config managed and custom rules
- Drift detection policies (OPA or equivalent)
- Remediation functions (Lambda) with safeguards
- Alerting configuration (SNS and routing)
- Security Hub integration for drift findings
- Runbook and rollback steps
- Evidence pack: drift event logs, remediation logs, before/after state
Secure CI/CD Pipeline
Security gates throughout delivery. Secrets scanning, SAST, infrastructure validation, artifact signing, and approvals.
Why it matters: A pipeline without security gates is a deployment path for vulnerabilities. Gates at each stage make insecure deploys structurally difficult.
Deliverables
- Pipeline security architecture
- Secrets scanning integration
- SAST integration (Semgrep/CodeQL or equivalent)
- Infrastructure validation gates (Terraform + policy)
- Artifact signing and provenance
- Deployment approval workflows
- Evidence pack: gate outputs, signing proof, approvals trail
