As US companies accelerate their shift toward cloud-native architectures, AWS has become the preferred platform for everything from SaaS applications and fintech infrastructure to healthcare systems and AI/ML pipelines. However, this rapid cloud adoption has also created a significantly larger attack surface. In 2025, security threats are more sophisticated, compliance audits are stricter, and regulators expect companies to enforce airtight cloud governance.

Ransomware gangs now target cloud misconfigurations, insider threats continue to rise, and data exposure from poorly secured S3 buckets still ranks among the most common security incidents in the US. Add remote work, distributed engineering teams, and the growing complexity of multi-account architectures – and AWS security is no longer optional; it is a business-critical discipline.

Fortunately, AWS provides a powerful suite of native security services, such as GuardDuty, Security Hub, IAM Identity Center, AWS WAF, Shield, Macie, Inspector, KMS, and CloudTrail. But the challenge is not availability – it’s correct configuration and continuous monitoring. Most breaches happen not because AWS lacks security features, but because teams fail to enable them, enforce them, or automate them.

At the same time, US companies must comply with regulatory frameworks such as:

HIPAA for healthcare data
SOC 2 for SaaS and B2B services
PCI DSS for payment data
NIST 800-53 & FedRAMP for government-facing systems

These frameworks map directly to AWS security best practices, but only if companies implement the right controls.

This guide breaks down the top 10 AWS security best practices for 2025, combining AWS-native tools with compliance-aligned strategies. Whether you’re a startup looking to strengthen your baseline, or an enterprise preparing for a SOC2/HIPAA audit, this guide gives you a practical, actionable security roadmap.

Enforce IAM Best Practices (Least Privilege, MFA, Identity Center)

Identity is the foundation of AWS security. In nearly every cloud breach reported over the last few years, the root cause traces back to misconfigured access controls overly permissive IAM users, exposed access keys, missing MFA, or unclear permission boundaries. Strengthening identity and access management is the first and most critical security best practice for any US company running workloads on AWS.

The principle you must enforce is simple: never grant more access than needed, and never rely on long-term credentials.

AWS Identity and Access Management (IAM) and AWS IAM Identity Center (formerly AWS SSO) provide the tools to implement strong, least-privilege access across your organization.

Use IAM Roles Instead of Access Keys

Long-lived access keys are one of the biggest risks in cloud environments. Keys can be leaked in:

GitHub repositories
CI/CD pipelines
Developer laptops
Scripts and configuration files

Replace them with IAM roles + short-term credentials issued via STS. This eliminates key exposure and dramatically reduces the blast radius of compromised credentials.

Enforce MFA on All Privileged Accounts

Every root and admin-level user must have Multi-Factor Authentication enabled. MFA is a mandatory requirement for SOC2, HIPAA, and PCI DSS compliance, and it blocks a large percentage of unauthorized access attempts.

Use AWS IAM Identity Center for Centralized Access

Identity Center allows teams to:

Integrate SSO with Okta, Azure AD, Google Workspace
Assign permission sets instead of individual IAM roles
Standardize user provisioning and deprovisioning
Track access centrally

This reduces identity sprawl and enforces consistent access governance across multiple AWS accounts.

Grant Least-Privilege Permissions

Use managed policies only when necessary; otherwise create fine-grained, custom permission boundaries. Regularly audit:

Users
Roles
Policies
Keys (if any)

Use AWS Organizations & SCPs for Governance

As companies scale into multiple AWS accounts – development, staging, production, analytics, security, sandbox environments – the complexity of governance increases dramatically. Without centralized controls, teams can accidentally deploy resources in the wrong region, disable logging, create overly permissive IAM policies, or expose public endpoints that violate compliance.

This is where AWS Organizations and Service Control Policies (SCPs) become essential. They provide a unified, top-down governance model that ensures every account follows mandatory security rules, regardless of who creates resources.

Structure Your AWS Environment With a Multi-Account Strategy

AWS recommends separating workloads across accounts rather than isolating them only with VPCs. A well-designed structure includes:

Security account: central logging, GuardDuty, Security Hub
Shared services account: CI/CD, networking
Workload accounts: per-app or per-team
Sandbox accounts: safe experimentation for developers

This reduces the blast radius, improves compliance mapping, and simplifies auditing.

Enforce Guardrails Using Service Control Policies (SCPs)

SCPs allow you to define what cannot be done across your organization. For example, you can prevent:

Disabling CloudTrail
Creating IAM users
Making S3 buckets public
Launching unapproved instance types
Deploying resources outside allowed regions

SCPs act as a global “deny layer,” ensuring that even administrators cannot break security baselines.

Centralize Billing, Logging & Permissions

With AWS Organizations, you can consolidate:

Billing (for cost visibility)
CloudTrail logs (for compliance)
Security findings (via Security Hub)
Identity governance (via IAM Identity Center)

This aligns with SOC2 CC1 (control environment), PCI DSS 12, and HIPAA administrative safeguards.

Benefits for US Companies

A centralized governance model reduces operational risk, simplifies audits, and ensures consistent application of AWS security services across all environments.

is aligned directly with SOC2 CC6 and HIPAA 164.308 access control requirements.

Enable Encryption Everywhere (KMS, SSE, TLS)

Encryption is one of the strongest security controls available on AWS and one of the easiest to implement. Yet many breaches still occur because data was stored in plaintext, encryption was not enforced, or keys were improperly managed. For US companies handling sensitive information especially healthcare, finance, or customer data encryption is both a security requirement and a compliance mandate.

AWS follows a shared responsibility model:
AWS secures the infrastructure, but you must encrypt your data.

Encrypt All Data at Rest Using AWS-Managed or Customer-Managed Keys

Every major AWS storage service supports encryption:

S3 – Server-Side Encryption (SSE-S3 or SSE-KMS)
EBS – Volume encryption with KMS keys
RDS & Aurora – Transparent data encryption
EFS & FSx – Integrated KMS encryption
Redshift – Cluster-level encryption

For most regulated workloads, SSE-KMS (with AWS KMS keys) is the recommended choice it provides full auditability and granular control.

Use Customer-Managed Keys (CMKs) When Compliance Requires It

US companies under HIPAA, PCI DSS, or SOC2 often need more control over:

Key rotation
Key deletion
Key access policies
Audit logs

Customer-managed keys offer these capabilities and allow fine-grained permission management using IAM.

Encrypt Data in Transit (TLS 1.2 or Higher)

Every application should enforce:

HTTPS for public endpoints
TLS encryption for internal APIs
Encrypted connections for RDS, ElastiCache, Redshift, and EKS pods

AWS ALB, CloudFront, and API Gateway make it easy to enforce TLS 1.2+.

Restrict Who Can Access KMS Keys

Encryption is only as strong as the policies securing your keys. Limit who can:

Use keys
Rotate keys
Schedule key deletion

Every key action is logged in CloudTrail, which supports SOC2 CC6, PCI DSS 3.x, and HIPAA 164.312 compliance mapping.

Strengthen Network Security With VPC Best Practices

A secure network architecture is essential for protecting workloads on AWS. Most cloud breaches occur not because attackers “break in,” but because companies unknowingly expose resources to the public internet or fail to isolate sensitive systems. Amazon VPC provides the tools to build a tightly controlled, private network but only if configured correctly.

Use Private Subnets for Sensitive Workloads

Databases, backend services, cache clusters, internal APIs, and analytics engines should never reside in public subnets. Place them in private subnets with no direct internet exposure. Outbound access, if required, should flow through:

NAT Gateways
VPC endpoints
Transit Gateway (for hybrid setups)

This reduces attack surface and aligns with SOC2 Logical Access requirements.

Enforce Layered Security With Security Groups and NACLs

Security Groups act as stateful firewalls; NACLs provide stateless filtering. Together, they help:

Restrict east–west traffic
Prevent lateral movement
Limit access to specific ports/IP ranges

Follow a “deny by default, allow by exception” model.

Use VPC Endpoints to Access AWS Services Privately

Instead of routing traffic over the public internet, use VPC Interface Endpoints (PrivateLink) or Gateway Endpoints for:

S3
DynamoDB
Secrets Manager
SQS
CloudWatch

This ensures all traffic stays inside AWS’s private network and supports HIPAA and PCI DSS encryption-in-transit requirements.

Block Public Access at the Network Level

Prevent accidental exposure by:

Disabling public IP assignment
Enforcing Internet Gateway restrictions
Using AWS Organizations SCPs to block forbidden actions
Enabling S3 Block Public Access

A misconfigured security group should never be able to expose an entire workload.

Monitor Network Traffic Continuously

Enable:

VPC Flow Logs
GuardDuty
Network Access Analyzer

These detect anomalies, suspicious IPs, and unintended data flows.

Use AWS Security Services for Continuous Threat Detection

Security on AWS is not a one-time setup – it’s a continuous monitoring process. Threats evolve, infrastructure changes, developers deploy new features, and security configurations drift over time. AWS provides a suite of native security services that automate detection, alerting, and remediation, making it possible for US companies to maintain a strong security posture without building their own security tools from scratch.

Enable AWS GuardDuty for Intelligent Threat Detection

GuardDuty uses machine learning and threat intelligence to detect:

Unusual API calls
Compromised credentials
Malicious IP interactions
Crypto-mining attempts
Lateral movement

It protects your environment without requiring agents or complex deployments.

Use Amazon Inspector for Vulnerability Scanning

Inspector automatically scans:

EC2 instances
ECR container images
Lambda functions

It identifies software vulnerabilities, misconfigurations, and exposures. As US companies adopt containers and microservices, Inspector becomes essential for runtime security.

Enable AWS Security Hub for Centralized Findings

Security Hub aggregates data from:

GuardDuty
Inspector
Macie
IAM Access Analyzer
Firewall Manager
Third-party tools (CrowdStrike, Splunk, Datadog)

It provides consolidated dashboards mapped to CIS, NIST, PCI DSS, and SOC2 benchmarks.

Use AWS Macie for Data Loss Prevention (DLP)

Macie automatically discovers and classifies sensitive data in S3, such as:

PHI (protected health information)
PII (personal identifiable information)
Credit card details

This is critical for HIPAA and PCI DSS compliance.

Turn On CloudTrail & CloudWatch for Audit Logging

CloudTrail records every API call; CloudWatch provides real-time monitoring and alerting. Together they form the foundation for:

SOC2 auditing
HIPAA access tracking
Forensic analysis
Incident response

No AWS environment is secure without CloudTrail enabled in every region.

Implement Zero Trust Access Controls

Traditional security models assumed that anything inside the network was trustworthy. That approach no longer works – remote teams, distributed systems, public cloud workloads, and identity-based access require a Zero Trust model. On AWS, Zero Trust means verifying every request, enforcing continuous authorization, and ensuring no user or workload has implicit trust.

Replace Trust Assumptions With Identity-Based Access

AWS Identity and Access Management (IAM) enables fine-grained policies that restrict exactly who can perform which actions on which resources. Instead of relying on network boundaries, Zero Trust shifts security to identity:

Assign IAM roles to workloads
Use IAM Identity Center for human users
Apply permission boundaries to limit escalation
Use STS-issued short-lived credentials

This limits lateral movement and protects against compromised accounts.

Use Micro-Segmentation in Your AWS Architecture

In a Zero Trust environment, applications communicate only with the services they require. You can enforce this through:

Security Groups with narrow rules
VPC endpoint policies
Kubernetes network policies (for EKS)
Application Load Balancers with strict routing rules

Micro-segmentation prevents attackers from moving freely within your systems.

Adopt AWS PrivateLink and VPC Lattice for Private Communication

AWS PrivateLink ensures services such as S3, DynamoDB, or internal APIs are accessed privately, without traversing the public internet. VPC Lattice (for service-to-service communication) adds identity-based access controls at the application layer, enhancing Zero Trust consistency across microservices.

Continuously Validate Access and Monitor Behavior

Zero Trust is not set-and-forget. Use:

GuardDuty for anomaly detection
CloudTrail to monitor API behavior
Security Hub for suspicious patterns
IAM Access Analyzer to detect unintended access

This continuous validation aligns directly with SOC2 and HIPAA access control requirements.

Protect Data in S3 With Strong Security Controls

Amazon S3 is one of the most widely used services in AWS – and one of the most common sources of security breaches when misconfigured. Public bucket exposure, overly permissive access policies, and lack of auditing have led to high-profile data leaks across the US. Securing S3 requires applying AWS’s built-in controls consistently.

Block Public Access at the Account and Bucket Level

The most effective protection starts with enabling S3 Block Public Access across your entire AWS account. This prevents:

Accidental public ACLs
Public bucket policies
Unintended exposure of sensitive files

For HIPAA, SOC2, and PCI DSS workloads, public S3 buckets should never be allowed unless explicitly required (e.g., static website hosting).

Use IAM Policies and Bucket Policies With Explicit Deny

Avoid using overly broad permissions like s3:* or s3:GetObject on “*” resources. Instead:

Grant access only to specific prefixes or buckets
Use resource-level conditions
Deny access unless requests originate from approved VPC endpoints or IAM roles

This ensures that even privileged accounts cannot bypass security boundaries.

Enforce Encryption With SSE-KMS

Server-Side Encryption with AWS KMS (SSE-KMS) enables:

Key-level access control
Audit logging of every key usage
Secure key rotation

This is mandatory for most regulated industries, including healthcare (HIPAA) and finance (PCI DSS).

Use S3 Object Lock for Compliance Retention

Object Lock enforces Write-Once-Read-Many (WORM) retention, preventing anyone- even administrators- from deleting or modifying files until the retention period expires. It is invaluable for:

Audit logs
Legal records
Compliance archives
Forensic snapshots

This directly supports SOC2 and FINRA retention requirements.

Monitor S3 With Macie and CloudTrail

Amazon Macie automatically identifies sensitive data (PII, PHI, financial information).
CloudTrail logs every object access and API action, enabling detection of unusual access patterns.

Harden EC2, EKS, and Containers

As US companies adopt microservices, Kubernetes, and container-based architectures, the attack surface expands rapidly. Amazon EC2 instances, EKS clusters, Docker images, and running containers all require continuous hardening to prevent vulnerabilities from turning into full-blown breaches. Security in these environments must be automated, consistent, and tightly integrated with AWS-native services.

Harden EC2 Instances With Secure Configurations

A secure EC2 environment begins with:

Patching automation using AWS Systems Manager Patch Manager
IMDSv2 enforced to block metadata exploitation
Minimal-access IAM roles assigned per instance
Encrypted EBS volumes for all disks

Use Systems Manager (SSM) Session Manager to replace unsecured SSH access. This removes the need for public bastion hosts and ensures full auditability of all administrative actions.

Secure EKS Clusters Using Kubernetes Best Practices

Kubernetes provides flexibility – but misconfigurations can be dangerous. Strengthen your cluster by enabling:

IRSA (IAM Roles for Service Accounts) to avoid static credentials
Network Policies to restrict pod-to-pod communication
Runtime threat detection using Inspector or third-party tools
Private cluster endpoints so the control plane isn’t exposed

Always scan container images stored in Amazon ECR and enforce signed, trusted base images across your CI/CD pipeline.

Use Container Vulnerability Scanning and Policy Enforcement

Modern container security requires:

Automated image scanning
Dependency vulnerability analysis
Misconfiguration detection
Policy enforcement (e.g., blocking images with critical CVEs)

Amazon Inspector integrates directly with ECR to identify vulnerabilities before images reach production.

Lock Down Permissions and Networking for Compute Workloads

Whether running on EC2 or EKS:

Assign least-privilege IAM roles
Restrict Security Groups by port and source
Use PrivateLink, not public endpoints
Monitor all API and container activity through CloudTrail and GuardDuty

Together, these controls create a hardened compute environment aligned with SOC2 CC7, HIPAA 164.308, and PCI DSS secure configuration requirements.

Enable Automated Backups & Disaster Recovery

Even the most secure AWS environment remains vulnerable without strong backup and disaster recovery plans. Hardware failures, human errors, ransomware attacks, data corruption, or region-level outages can still disrupt operations. Automated backups and well-tested DR strategies ensure business continuity – a requirement emphasized across SOC2, HIPAA, and PCI DSS.

Automate Backups Across Databases and Storage

Enable automated backups for:

RDS & Aurora (point-in-time restore, automated snapshots)
DynamoDB (on-demand or continuous backups)
EFS-to-EFS Backup
EC2 snapshots
EBS snapshot lifecycle policies

Use AWS Backup to centralize policies, retention periods, and compliance requirements across all accounts.

Implement Disaster Recovery Based on Your RTO & RPO

Different businesses need different levels of resilience. AWS supports multiple DR models:

Backup & Restore – lowest cost, higher recovery time
Pilot Light – minimal infrastructure running, faster recovery
Warm Standby – partially running environment in another region
Multi-Region Active/Active – highest performance and availability

Map your DR strategy to regulatory requirements and business-critical workloads.

Integrate Backup Monitoring and Compliance

AWS Backup Audit Manager evaluates whether your backups meet:

Retention mandates
Encryption requirements
Backup frequency policies
Cross-region protection rules

This helps satisfy HIPAA 164.308(a)(7), SOC2 Availability, and PCI DSS continuity controls.

Test Your Recovery Regularly

A DR plan is only successful if validated. Conduct:

Restore drills
Failover simulations
Region outage tests
Access recovery assessments

Regular testing ensures your recovery procedures actually work during an incident.

Implement Continuous Compliance & Auditing

Security is not a one-time configuration it’s an ongoing discipline. For US companies subject to SOC2, HIPAA, PCI DSS, or federal frameworks, continuous compliance is now mandatory. AWS provides several native tools that automate auditing, detect misconfigurations, and ensure that your cloud environment stays compliant every day, not just during audit season.

Use AWS Config to Track Every Configuration Change

AWS Config continuously evaluates resources such as:

S3 buckets
Security groups
IAM roles
KMS keys
VPC configurations
RDS, DynamoDB, EFS, and Lambda settings

You can enforce compliance rules like:

“S3 buckets must be encrypted.”
“Security groups cannot allow 0.0.0.0/0 on port 22.”
“CloudTrail must be enabled in all regions.”

AWS Config provides remediation actions that automatically fix violations ideal for SOC2 CC7, HIPAA technical safeguards, and PCI DSS 2.x/6.x.

Use AWS Audit Manager for SOC2, HIPAA & PCI DSS Readiness

Audit Manager maps AWS services to compliance requirements and generates evidence automatically. It reduces weeks of manual spreadsheet work during audits by:

Collecting logs
Mapping them to controls
Producing ready-to-submit audit artifacts

This is especially powerful for enterprises and SaaS companies undergoing recurring SOC2 Type II evaluations.

Use Security Hub Compliance Packs

AWS Security Hub includes compliance frameworks such as:

CIS AWS Foundations Benchmark
PCI DSS
NIST 800-53
SOC2
Foundational Security Best Practices

It aggregates findings from GuardDuty, Inspector, Macie, IAM Access Analyzer, and Config, giving teams a unified compliance posture across accounts.

Keep CloudTrail Enabled in All Regions

CloudTrail is the single most important logging service on AWS. It provides a complete API history for:

Incident investigation
Forensic analysis
Access tracking
Regulatory audits

Disabling CloudTrail (intentionally or not) should be impossible use AWS Organizations SCPs to enforce this safeguard.

AWS Security Compliance Mapping (SOC2, HIPAA, PCI DSS)

For US companies operating in regulated industries, AWS security is not just about best practices – it’s about meeting formal compliance requirements. SOC2, HIPAA, and PCI DSS all demand strict controls around identity, data security, encryption, monitoring, and change management. AWS provides the building blocks, but companies must configure and maintain them correctly.

Below is a simplified compliance mapping that shows how AWS security services align with real-world audit requirements.

Why Compliance Mapping Matters

Compliance teams, security architects, auditors, and CISOs rely on such mappings to:

Prove that AWS configurations meet regulatory standards
Accelerate SOC2 and HIPAA readiness
Eliminate manual evidence collection
Reduce audit friction and costs
Create repeatable security baselines across accounts

AWS provides the technical controls, but continuous monitoring, remediation, and governance ensure that compliance is maintained- not just during audit preparation, but year-round.

Final Summary - Secure Your AWS Environment the Right Way

AWS offers one of the most secure cloud platforms in the world but only when companies configure, monitor, and govern it correctly. In 2025, US businesses face a new wave of threats: ransomware campaigns targeting unpatched systems, insider risks, misconfigured identity policies, public bucket exposures, and supply-chain vulnerabilities. Compliance frameworks like SOC2, HIPAA, and PCI DSS now expect continuous monitoring, encryption everywhere, strong identity governance, and clear incident response procedures.

The top AWS security best practices covered in this guide from IAM hardening and Zero Trust controls to encryption, continuous threat detection, S3 protection, vulnerability scanning, and automated compliance create a solid foundation for securing cloud workloads at any scale.
