Amazon GuardDuty has expanded its RDS Protection capabilities to identify data exfiltration and destruction attacks targeting Amazon Aurora PostgreSQL and RDS for PostgreSQL. This new RDS Protection for data activity uses machine learning and threat intelligence to monitor query patterns for anomalies, requiring no agents or configuration changes. The update addresses the growing threat of attackers using valid credentials to steal or wipe data after initial compromise.

  • Detects data exfiltration and destruction, not just login anomalies.
  • Applies to Aurora PostgreSQL and RDS for PostgreSQL only.
  • Uses ML and threat intelligence for continuous query monitoring.
  • Zero-config deployment with no agents or infrastructure needed.
  • Targets threats exploiting valid credentials via phishing or misconfig.

Amazon EventBridge now supports enhanced custom event buses that enable centralized bus sharing across multiple AWS accounts. Key additions include ordered delivery guarantees, simplified subscriber management, event replay capabilities, and content-based deduplication. The announcement also introduces a new publisher/subscriber-based pricing model to replace previous structures.

  • Centralized multi-account bus sharing simplifies cross-account event routing.
  • Ordered delivery and replay features improve reliability for stateful consumers.
  • Content-based deduplication reduces redundant processing and noise.
  • Publisher/subscriber pricing model may alter cost expectations for high-volume buses.

AWS Network Firewall adds wildcard support for EKS/ECS container filters

AWS Network Firewall now supports wildcard patterns in container attribute-based inspection filters for Amazon EKS and ECS. This update allows administrators to match multiple container workloads, such as all variants of an application, using a single rule. The feature eliminates the need to manually create individual container associations for each new deployment variant.

  • Use wildcard patterns like app=payments-* to match multiple container variants in one rule.
  • Reduces operational overhead by avoiding manual association of individual container instances.
  • Ensures consistent security coverage as new application variants are deployed dynamically.
  • Applies to both Amazon EKS and Amazon ECS container workloads.
