How is the CISSP different from other security certifications?
The CISSP is a high-level security certification. The material covered will give you the overall view of IT security. In general the material covered does not include much that is particular to any one platform or brand of software. It is the big picture view. The advantage to this is that your skills will be transferable to any platform. Remember security is only as effective as its weakest link. If you are using very strong encryption but someone takes advantage of the fact that they are an insider or walks off with your hardware you have not accomplished much. Many breaches of security are not technical in nature.
