The latest AWS Security Digest (Issue 204) covers critical topics in cloud security, including misconfigured API Gateways, rising IAM threats, and Infrastructure as Code (IaC) ownership strategies. Read the full digest here: AWS Security Digest 204.
You Should Know:
1. Misconfigured API Gateways in AWS
Attackers can exploit misconfigured API Gateways to gain unauthorized access from external AWS accounts. Below are key commands to audit your API Gateway configurations:
AWS CLI Commands to Check API Gateway Permissions:
aws apigateway get-rest-apis aws apigateway get-resources --rest-api-id <API_ID> aws apigateway get-method --rest-api-id <API_ID> --resource-id <RESOURCE_ID> --http-method GET
Mitigation Steps:
- Enable AWS CloudTrail to monitor API Gateway activity:
aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=UpdateRestApi
- Apply least privilege policies using AWS IAM:
aws iam create-policy --policy-name APIGatewayLeastPrivilege --policy-document file://policy.json
2. Rising IAM Threats & Exfiltration Risks
Attackers increasingly target AWS IAM roles for privilege escalation. Use these commands to detect suspicious activity:
Check IAM Role Permissions:
aws iam list-roles aws iam list-attached-role-policies --role-name <ROLE_NAME>
Detect Anomalous IAM Activity:
aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=AssumeRole
Enable AWS GuardDuty for Automated Threat Detection:
aws guardduty create-detector --enable
3. IaC Ownership via Tag-Based Approach
Managing Infrastructure as Code (IaC) requires proper tagging for accountability. Use AWS Systems Manager to enforce tagging:
Enforce Tagging on EC2 Instances:
aws ec2 create-tags --resources i-1234567890abcdef0 --tags Key=Owner,Value=DevTeam
Audit Untagged Resources:
aws resourcegroupstaggingapi get-resources --tag-filters Key=Owner,Values=
What Undercode Say:
AWS security requires continuous monitoring, least privilege enforcement, and automated threat detection. Key takeaways:
– Audit API Gateway permissions to prevent cross-account exploits.
– Monitor IAM roles for unusual `AssumeRole` activities.
– Enforce IaC tagging for better resource governance.
– Use GuardDuty & CloudTrail for real-time threat detection.
Expected Output:
A hardened AWS environment with reduced attack surface, automated security checks, and clear IaC ownership tracking.
