ALEX NOORDERGRAAF has over 10 years' experience in the area of Computer and Network Security. As a security architect of the Enterprise Server Products (ESP) group at Sun Microsystems, he is responsible for the security of midframe and high-end Sun servers. He is a co-founder of the very popular freeware Solaris Security Toolkit. Prior to his role in ESP, he was a senior staff engineer in the Enterprise Engineering (EE) gourp, where he developed, documented, and published security best practices through the Sun BluePrints program. Published topics include security for Sun Fire servers, Sun Cluster software, Sun Fire Midframe servers, Sun Enterprise 10000 servers, N-Tier environments, the Solaris OE, and Solaris OE Network settings. He co-authored the Sun BluePrints publications, Jumpstart Technology: Effective Use in the Solaris Operating Environment.
Before joining ESP, he was a senior architect with Sun Professional Services (SunPS) where he worked with many Fortune 500 companies in projects that included security assessments, architecture development, architectural reviews, and policy/procedure review and development. He developed and delivered an enterprise security assessment methodology and training cirriculum that is used worldwide by SunPS. His customers included major telecommunication firms, financial institutions, ISPs, and ASPs. Before joing Sun, Alex was an independent contractor specializing in network security. His clients included BTG, Inc. and Thinking Machines Corporation.
