How We Strengthened AWS Security for a Leading B2C Multi-Brand Service Provider With a 63% Improvement in Data Protection

Misconfigurations and weak controls across IAM, data, and infrastructure increased security and operational risks

As the client scaled their AWS environment across multiple locations and brands, gaps in security, configuration, and monitoring became apparent. Weak identity and access controls, limited data protection, unencrypted resources, and insufficient logging and governance increased operational and security risks. These issues highlighted the need for a structured assessment to guide improvements across identity, data protection, infrastructure, monitoring, and threat detection.

Streamlined AWS security assessment and actionable roadmap

We collaborated closely with the client to carry out a detailed AWS security assessment across identity, data protection, infrastructure, monitoring, and threat detection. Our approach delivered a structured roadmap with targeted improvements:

Strengthening Identity & Access Management Strong password policies were enforced, access key rotation was implemented, and automatic secrets rotation in AWS Secrets Manager was enabled to eliminate long-lived credentials.

Enhancing Data Protection Public access to Redshift was restricted and audit logging was activated to safeguard sensitive data. Encryption was enforced across EBS volumes and SNS topics, S3 access logging and versioning were enabled for better tracking and recovery, and KMS key rotation was activated to ensure proper encryption key management.

Securing Infrastructure Resources Termination protection was enabled for both EC2 instances and CloudFormation stacks to prevent accidental deletions. DMS tasks were validated to improve data migration reliability, and image scanning on push was activated in ECR to mitigate container vulnerabilities. Enhanced monitoring was also applied to EC2 instances and RDS databases for better performance visibility.

Upgrading Logging & Monitoring VPC Flow Logs was enabled to improve network traffic visibility. CloudWatch anomaly detection was activated to detect unusual activity, and log encryption was enforced. S3 buckets were also configured with access logging and versioning to strengthen auditability and recovery capabilities.

Improving Threat Detection & Governance GuardDuty and Security Hub were deployed for automated, continuous threat detection across the environment. Additionally, AWS Control Tower was introduced to centralize governance and streamline compliance management across accounts.

55% enhanced threat visibility and 63% operational continuity
