Real-Time Log Analytics & Security Monitoring Platform

Cloud Security Project

You were been asked by the Chief Information Officer to build-out a cloud native Security Information and Event Managment (SIEM) system that should be able to support both the DevOps and Application team as they migrate their workload to the cloud.

Operations & Observability

Focus: Keeping the "lights on" through monitoring and automated recovery.

The Project: Build a Centralized Logging & Alerting System.

Key Tasks:

  • Configure Organizational Cloudtrail Logs to an s3 bucket

  • Use CloudWatch Logs and VPC Flow Logs to monitor traffic.

  • Configure Continuous Security Monitoring using AWS Security Hub

  • Using AWS Guard duty for automated threat detection and response

  • Set up CloudWatch Alarms that trigger SNS notifications (e.g., Slack/Email) when CPU or 4xx errors spike.

  • Implement AWS Config to monitor for non-compliant resources (e.g., unencrypted S3 buckets).

  • Advanced Twist: Use AWS Systems Manager (SSM) to patch EC2 instances automatically without SSH.
