ABSTRACT
Although this book has “Advanced Topics” in its title, the topics covered may look familiar as common capabilities enterprises are deploying. What is advanced is not the topic, but the approach to provide capabilities for that topic in accordance with a consistent security model based on sound principles. Security always requires “moving forward to stand still.” The problem we attempt to address in this book is how to design a system that can be managed with a slow jog instead of a constant, frenzied sprint. The fact that the original book on Enterprise Level Security (ELS) has a sequel suggests that this work is ongoing. Even as we finish writing this book, we see many new challenges and opportunities on the horizon. Quantum computing threatens to disrupt cryptography, which is the foundation of many security protocols that we use today. Homomorphic encryption and computation are seeing rapid growth. 5G and IoT together will change what the Internet means. Artificial intelligence is promising to aid security decisions while simultaneously threating to break them. With proper care, we anticipate that each of these can be integrated into the ELS design to expand capabilities while maintaining a solid security foundation.
