AWS GuardDuty extends threat detection for EC2 and ECS

🔍 AWS announced an update to GuardDuty Extended Threat Detection that adds multistage attack detection for Amazon EC2 instances and Amazon ECS clusters running on Fargate or EC2. The release introduces two critical findings — AttackSequence:EC2/CompromisedInstanceGroup and AttackSequence:ECS/CompromisedCluster — that group related events into a single, high-priority alert. Findings include a summary, event timeline, MITRE ATT&CK mappings, and remediation guidance to speed response. Runtime Monitoring must be enabled for full coverage, and customers can try the feature free for 30 days.

Automated AWS Integration: CrowdStrike Falcon Next-Gen SIEM

🛡️ AWS and CrowdStrike have launched an automated integration experience for CrowdStrike Falcon Next-Gen SIEM in AWS Marketplace that streamlines cloud-native security monitoring. The guided wizard automates connector configuration and provisions least-privilege IAM roles, Amazon SQS queues, EventBridge rules, and SNS topics. Security teams can quickly enable agentic AI-assisted investigation, advanced correlation, and automated response across their AWS Organization, and subscribe via new pay-as-you-go pricing.

Practical Steps to Minimize Key Exposure in AWS Environments

🔐 This AWS Security blog by Jennifer Paz outlines a layered, practical approach to reduce exposure from long‑term AWS credentials. It recommends discovery and risk assessment with CodeGuru Security, IAM Access Analyzer, credential reports, and Trusted Advisor, followed by enforcement using SCPs and RCPs to create a network data perimeter. The post also covers runtime protections (security groups, NACLs, Network Firewall, AWS WAF), automated rotation using Secrets Manager or rotation patterns, and threat detection via GuardDuty, all intended to bridge the gap until migration to temporary credentials is feasible.

Amazon GuardDuty Malware Protection for AWS Backup

🔒 Amazon announced GuardDuty Malware Protection for AWS Backup, extending malware detection to backups of Amazon EC2 instances, Amazon EBS volumes, and Amazon S3 objects. The capability automatically scans new backups, supports on-demand scans of existing backups, and can identify the last known clean backup to reduce recovery impact. It offers incremental scanning to analyze only changed data between backups, lowering costs versus full rescans, and can be enabled even if GuardDuty foundational data sources are not active. The feature is available in supported Regions and accessible via the AWS Backup console, API, or CLI.

Planning and Running an AWS Security Hub POC Guide

🔒 This post explains how to plan and implement an AWS Security Hub proof of concept (POC) to evaluate unified cloud security operations. It outlines steps to define success criteria, configure integrations with GuardDuty, Amazon Inspector, Macie, and Security Hub CSPM, and to prepare, enable, and validate the deployment. The guidance recommends using overlapping trial periods, adopting the OCSF standard for normalized findings, and leveraging automation and ticketing integrations to measure operational impact.

Security Services Available in AWS Dedicated Local Zones

🛡️ This post explains how organizations can use AWS security services while keeping data within Dedicated Local Zones. It describes the AWS Nitro System for hardware-enforced isolation, AWS KMS with an external key store option, and continuous protection from Amazon Inspector and GuardDuty. It also covers certificate management via ACM, DDoS mitigation with AWS Shield, and centralized auditing through CloudTrail.

Amazon GuardDuty Adds Custom Entity Lists for Domains

🛡️ AWS announced general availability of Amazon GuardDuty custom threat detection using entity lists, extending support beyond IP-only lists to include malicious domains and IP addresses. GuardDuty introduces a new finding type, Impact:EC2/MaliciousDomainRequest.Custom, triggered when activity related to a listed domain is observed. Entity lists also allow suppression of alerts from trusted sources and simplify cross-region permission management, avoiding IAM policy size limits. The feature is available in all GuardDuty Regions except China and GovCloud (US).

Amazon GuardDuty Adds Custom Entity Lists for Detection

🛡️ AWS announced general availability of Amazon GuardDuty custom threat detection using entity lists, expanding support beyond legacy IP-only lists to include domains and mixed IP/domain lists. The service adds a new finding type, Impact:EC2/MaliciousDomainRequest.Custom, when activity involves a listed domain. Entity lists can also be used to suppress alerts from trusted sources, and they simplify permissions and cross-region management. The capability is available in all Regions where GuardDuty runs, excluding China and GovCloud (US).
