Information security is the foundation of enterprise information framework, and a strong enterprise information framework benefits business growth. Information security management system combined with business data can provide more effective service for enterprise. When IC production enters into the nanometer generation, more and more semiconductor manufacture companies have taken a lot of effort in information security area to prevent company information security. Lots of traditional security approaches are deployed, such as firewall, IDS, HIPS, anti-virus, DLP. But these products and applications like information islands, to protect sensitive data independently. This paper tempts to analysis semiconductor industry security requirements and to describe our practice on building up a high-performance Light SIEM. The Light SIEM system links with different security products and applications, correlates business data with information security management, and an effective approach to support enterprise information security management, including threat detection and security incident response and reports for compliance purposes.
