In 2016, the importance of maintaining secure services and preventing unauthorized access was underscored by previous high-profile cyberattacks on companies like Sony and Anthem, which suffered significant financial and data losses. This text introduces Security Information and Event Management (SIEM) as a comprehensive approach to IT security management, combining Security Event Management (SEM) and Security Information Management (SIM) to provide real-time analysis, centralized log storage, and automatic reporting. Using the ELK Stack (Elasticsearch, Logstash, and Kibana) alongside Amazon Web Services (AWS), the article outlines a step-by-step process to build a custom SIEM solution, emphasizing the integration of AWS CloudTrail and VPC Flow logs for effective monitoring and threat detection. The creation of dashboards and alerts in Logz.io, an ELK-as-a-service platform, is also covered, allowing users to visualize data, track anomalies, and set rule-based alerts to enhance security measures. The article concludes by advocating for proactive threat intelligence to safeguard resources against increasing cyber threats such as botnet attacks.
