This allows you to protect applications deployed on these services without requiring additional infrastructure.
Compliance and Regulatory Requirements: AWS WAF helps you meet compliance requirements (e.g., PCI DSS) by providing protection against web-based attacks and offering features like logging and monitoring that support auditing and reporting.
AWS CloudTrail
Visibility into AWS API Activity: CloudTrail records all API calls made in your AWS account, providing comprehensive visibility into who made the call, the source IP address, when the call was made, and other details. This audit trail helps you understand and track changes and activities across your AWS infrastructure.
Security and Compliance Auditing: CloudTrail aids in security monitoring and compliance auditing by capturing detailed information about API requests and changes to AWS resources. This information is crucial for investigating security incidents, conducting forensic analysis, and demonstrating compliance with regulatory requirements (e.g., GDPR, HIPAA, PCI DSS).
Operational Troubleshooting: It helps troubleshoot operational issues by providing a detailed history of API calls and changes to AWS resources. This can assist in diagnosing errors, identifying the source of operational problems, and understanding resource usage patterns.
Change Management and Governance: CloudTrail facilitates effective change management and governance by documenting changes to AWS resources over time. This enables administrators to track modifications, ensure accountability, and enforce governance policies related to resource configuration and access control.
Integration with AWS Services: CloudTrail integrates seamlessly with other AWS services such as AWS Config, AWS CloudWatch Logs, and AWS Security Hub. This allows you to correlate CloudTrail events with other monitoring and security data, enhancing your overall visibility and enabling automated responses to security events.
Centralized Logging and Monitoring: CloudTrail aggregates logs from multiple AWS accounts and regions into a centralized Amazon S3 bucket. This centralized logging simplifies log management, analysis, and retention policies, making it easier to maintain an audit trail across your AWS environment.
Real-time Event Notification: With CloudTrail, you can set up real-time notifications for specific API activities using Amazon SNS (Simple Notification Service). This proactive alerting mechanism allows you to respond promptly to critical events or unauthorized activities in your AWS account.
Granular Access Control: CloudTrail supports fine-grained access control through AWS Identity and Access Management (IAM), allowing you to restrict who can view or modify CloudTrail configurations and access log files. This helps enforce the principle of least privilege and enhances security posture.
Historical Analysis and Forensics: CloudTrail logs are retained for long periods (up to 90 days by default, extendable to years), allowing historical analysis and forensic investigations into security incidents or operational issues that occurred in the past.
Cost-Effective and Scalable: CloudTrail is a managed service with flexible pricing based on the volume of API events recorded. It scales automatically with your AWS infrastructure, handling large volumes of API activity without requiring manual intervention or additional infrastructure.
AWS Secrets Manager
