Securing Containerized Workloads: ISO Hardening on Amazon ECS

HAZERCLOUD implemented a secure, ISO-hardened containerized architecture on Amazon ECS (EC2) — with WAF, GuardDuty, AWS Config, CI/CD pipelines, and Multi-AZ redundancy for production-grade workloads.

The Challenges

Lacking production readiness and security posture.

The customer’s containerized workloads needed to move beyond a baseline setup — lacking production readiness, governance, and the security controls required to meet ISO standards on AWS.

Challenges

Infrastructure gaps and security risks

  • Existing setup lacked production readiness, scalability, and compliance enforcement
  • Manual deployments led to inconsistent releases and downtime across services
  • Security measures were minimal, with no IAM governance, WAF, or network flow visibility
  • Absence of centralised monitoring, auditing, or automated alert mechanisms
  • Required fault-tolerant data persistence and auto-scaling capability under variable loads
Goal

Secure, compliant, production-grade platform

  • Deploy containerized architecture on Amazon ECS with Multi-AZ redundancy
  • Implement automated CI/CD pipelines with zero-downtime deployments
  • Harden environment to ISO standards with AWS security best practices
  • Enable continuous monitoring, compliance tracking, and audit logging
  • Establish fault-tolerant data layer with caching and shared storage
The Solution

ISO-hardened containerized architecture. ECS, security, CI/CD.

HAZERCLOUD migrated to an ECS-based containerized architecture with ISO Hardening, AWS WAF, GuardDuty, CI/CD pipelines, and comprehensive monitoring — delivering a secure, compliant, production-grade platform.

Container Architecture

ECS-based containerized deployment on EC2

Migrated frontend, backend, and admin services to Amazon ECS on EC2 capacity provider with Multi-AZ redundancy, auto-scaling task definitions, and service discovery.

CI/CD Pipeline

Automated deployments with CodePipeline and CodeBuild

Implemented CI/CD pipelines with AWS CodePipeline and CodeBuild integrated with GitHub. Container images stored in ECR with ECS rolling deployments for zero-downtime releases.

Network & Security

VPC design with WAF, ALB, and ISO Hardening

Designed VPC with public/private subnets, ALB for intelligent traffic routing, and AWS WAF for application-layer security. IAM least-privilege policies enforced across all services following ISO Hardening standards.

Monitoring & Compliance

CloudWatch, Config, GuardDuty, and CloudTrail

Enabled CloudWatch for operational monitoring, AWS Config for compliance rules, GuardDuty for threat detection, CloudTrail for centralised audit logging, and SNS for automated alerting.

Architecture

The security architecture.

Amazon ECS on EC2 with public/private subnets, ALB, WAF, and security services — backed by RDS, EFS, ElastiCache, CI/CD pipelines, and centralised audit logging.
