Effective security incident response depends on adequate logging, as described in the AWS Security Incident Response Guide. If you have the proper logs and the ability to query them, you can respond more rapidly and effectively to security events.
This article provides an overview of the logging strategies that can be used to respond to security incidents in the cloud. It covers the different types of logs that can be used to track object level access when using S3 buckets to store confidential or sensitive data, such as CloudTrail, Elastic Load Balancing, CloudFront, AWS WAF, and Serverless logs. It also explains how to analyze the logs using Amazon Athena, Amazon OpenSearch Service, CloudTrail Event History, AWS CloudTrail Lake, and third-party SIEM solutions. Additionally, the article provides sample queries that can be used to investigate unauthorized attempts, rejected TCP connections, connections over older TLS versions, connections from an IP address, and user actions.
