Chapter 10. Security
Security is integral to any mission-critical enterprise-wide system. To paraphrase a recent animated hit movie, “Security is like an onion...it has layers.” Whether the system is a messaging system or a database system, there are many layers (FIGURE 10-1) when addressing security—each and every layer is integral to the overall security of the system. The question is how much effort is really appropriate for the level of security required.
