AWS Security Monitoring in 2023: Untangle the chaos

AWS security monitoring involves practices, tools, and processes to detect and respond to security threats in the Amazon Web Services (AWS) cloud. To effectively manage security in AWS, one should categorize services into three groups: sources of information, best practices and anomaly detection, and aggregation. Selecting the right combination of AWS services, such as AWS Config, AWS Security Hub, and optionally Amazon GuardDuty and Amazon Inspector, can help streamline security monitoring and reduce duplicate findings and costs. Additionally, setting up EventBridge rules to alert the right teams about new security findings is crucial for an efficient incident response process.
