Day One Book: Securing the Routing Engine on M, MX, and T Series

I work closely with many large, enterprise customers in the San Francisco Bay Area. One of the most common questions I receive is "how do we secure the router?" It's a very valid concern because in many of the implementation scenarios the routers are being directly exposed to the Internet, partners or customers.

Securing the Routing Engine for the M, MX and T Series is for anyone who is responsible for designing, implementing and maintaining security on Juniper routers. It isn't specific for enterprise or service provider customers, as the problems addressed in this book are common to all customers. The book is written by network engineers for network engineers.

This book arms the reader with all the tools requires to secure the routing engine. There are three primary building blocks in this book: firewall filters, policers and Junos configuration automation. The book is bundled with a security framework that the reader can instantly deploy into his or her environment with very little customization required.

It's generally accepted that there's a hard way of doing things and there's an easy way. I hope that it becomes self-evident how powerful Junos is compared to other network operating systems. Junos allows the network administrator to focus on the difficult problems while offloading repetitive and mundane tasks. Ultimately, Junos allows your business to "do more with less."

I have no specific book recommendation, but instead I encourage the reader to pursue a Junos certification. There are three tracks: enterprise, service provider, and security. Each track begins with the JNCIA-Junos certification and branches out from there. Each track has three levels certification: specialist, professional and expert. The certification process is a very challenging and rewarding experience. I'm currently going through the certification process and it has taught me to have a new level of respect of the amount of work and knowledge required to obtain the highest certificate of JNCIE.Find out more at http://www.juniper.net/us/en/training/certification/

I love writing. It's something that I wish I could do more of. I was fortunate enough to recognize a major concern out in the field and have the opportunity to work with Juniper to publish this book.

Chapter 2: Policers. I'm a visual learner and for a very long time I had trouble fully understanding how they actually work. Policers aren't a tangible thing you can pick up and take apart. If there are other readers that have difficulty understanding policers, I hope that this book clearly illustrates how they work and can be used.
