Compliance Framework Alignment
AWS maintains certifications across major compliance frameworks, but you must configure your environment correctly to inherit these certifications.
| Framework | AWS Coverage | Your Responsibility |
|---|---|---|
| SOC 2 | Infrastructure controls certified | Application-level controls, access reviews |
| HIPAA | BAA available, eligible services defined | PHI handling, access controls, audit logging |
| GDPR | Data processing agreement, EU regions | Consent management, data residency, DPO appointment |
| PCI DSS | Level 1 certified infrastructure | Application security, network segmentation, testing |
| ISO 27001 | Infrastructure certified | ISMS implementation, risk assessment, controls |
Use AWS Security Hub compliance standards (CIS Benchmark, PCI DSS, NIST 800-53) to continuously validate your configuration against these frameworks. For zero-trust architecture guidance, see our AWS zero trust guide.
What to Expect From an AWS Security Assessment
A comprehensive AWS security assessment evaluates your environment across identity, network, data protection, logging, and incident response domains. Key assessment components include:
- IAM policy review for over-privileged roles and unused credentials
- Network security analysis including VPC configuration, security groups, and NACLs
- Encryption posture assessment for data at rest and in transit
- Logging and monitoring coverage validation
- Incident response readiness evaluation
Opsio delivers security assessments that produce actionable findings ranked by risk severity, with remediation guidance and effort estimates for each finding.
Data Protection Best Practices
Effective data protection on AWS requires encryption everywhere, least-privilege access, and continuous monitoring for data exposure.
- Encrypt by default: Enable default encryption on S3 buckets, EBS volumes, RDS instances, and all data stores using AWS KMS
- Classify sensitive data: Use Amazon Macie to automatically discover and classify PII, financial data, and other sensitive information in S3
- Control access: Implement attribute-based access control (ABAC) and require MFA for all console and API access
- Monitor data movement: Configure VPC Flow Logs and S3 access logs to track data transfer patterns
- Backup and recovery: Use AWS Backup with cross-region replication for critical data protection
Incident Detection and Response
AWS GuardDuty processes billions of events daily to detect threats including compromised credentials, cryptocurrency mining, and data exfiltration. Build your detection and response capability with:
- GuardDuty enabled across all AWS accounts and regions
- Security Hub aggregating findings from GuardDuty, Inspector, Macie, and Firewall Manager
- Automated remediation using EventBridge rules and Lambda functions for common findings
- Runbooks for human-in-the-loop response to high-severity incidents
For managed security operations, contact our security team to discuss 24/7 threat monitoring and incident response services.
Frequently Asked Questions
What are the essential AWS security services every organization should enable?
At minimum, enable AWS CloudTrail (audit logging), GuardDuty (threat detection), Security Hub (posture management), IAM Identity Center (access management), and AWS Config (configuration compliance). These five services provide foundational security visibility.
How much does AWS security cost?
Core security services like IAM, KMS (first key), and Config rules have minimal or no additional cost. GuardDuty, Security Hub, and Inspector are priced based on data volume processed. Typical monthly cost for a medium AWS environment is $200-$1,000 for security tooling.
Can AWS meet HIPAA compliance requirements?
Yes, but compliance is a shared responsibility. AWS provides a Business Associate Agreement (BAA) and designates eligible services. You must configure those services correctly and implement application-level PHI protections.
How often should we conduct security assessments?
Perform a comprehensive assessment annually at minimum, with continuous automated checks through Security Hub. Trigger additional assessments after major infrastructure changes, security incidents, or regulatory updates.
What is the difference between GuardDuty and Security Hub?
GuardDuty is a threat detection service that analyzes CloudTrail, VPC Flow Logs, and DNS logs for suspicious activity. Security Hub aggregates findings from GuardDuty and other services, provides compliance checks, and serves as a central security dashboard.
