This White Paper is available as a PDF: OculanSecurity.pdf

Summary:

This white paper focuses on the processes and tools required to assemble and deploy a successful security solution. As with any technology-centric discussion of security, it spends a good amount of time discussing tools, but this does not preclude the necessity nor importance of having a well defined policy in place. Once completed, this security policy will help you to define and fill the needs for specific tools addressing specific risks.
