The text discusses the role of log management in security analytics, emphasizing the centrality of logs in systems like the ELK Stack, which comprises Elastic Search, Logstash, and Kibana. While traditional SIEM solutions such as AlienVault, QRadar, and Splunk offer comprehensive capabilities, the ELK Stack is increasingly being utilized as a more agile, cost-effective alternative for log management and analysis. However, it lacks certain out-of-the-box SIEM capabilities, requiring integration with additional tools for functionalities like alerting, correlation, and incident management. Various solutions have emerged to enhance ELK's capabilities in security analytics, such as Logz.io, which adds threat detection and dashboards, and Elastic SIEM, which offers a dedicated UI for event analysis but is still in beta. Wazuh, another option, provides a more comprehensive list of security-focused features while using ELK for log storage and analysis. Despite its limitations, ELK's open-source nature offers a solid foundation for developing more complete security systems, contributing to its growing popularity in the security analytics market.
