Finally getting caught up with work since my time in Cali and although this post is a little late, I wanted to take a moment to capture my thoughts on Juniper Network’s Data Center Cohesion event which took place in Sunnyvale at Juniper’s Aspiration Dome last week. I had an awesome time and the sessions were full of a ton of useful information geared towards all things Data Center. Apparently this was the first time that Juniper opened the conference to outside partners — roughly 16 partners showed up, so to say that I was honored to be there is quite an understatement.
On February 8th I gave a webinar on network modernization initiatives with Doug Nash, the Deputy Chief Information Officer, Operations & Infrastructure at the USDA.
I thoroughly enjoyed the opportunity to speak with Doug and discuss some of the new directions that various Federal agencies are undertaking to create more modernized and agile networks.
Data Centers and the Cloud are all the rage right now, and Juniper has been at the forefront of the Data Center revolution from the very beginning – early on with their introduction of the QFX and the much maligned QFabric, and more recently with the addition of Virtual Chassis Fabric (VCF), various open architectures for creating IP Clos Fabrics, and even advanced features such as Junos Fusion for the Data Center which collapse and simplify the deployment and management of a large number of Ethernet switches.
The JNCIP-DC is currently rated as the fifth hottest Data Center certification by Tom’s IT Pro, an online resource tracking the demand of various industry certifications.
I am delighted to announce that earlier this week I was accepted into Juniper’s Ambassador program. To say that I am completely honored is an understatement. Working with Juniper’s products and technologies has been a labor of love for me dating back almost 18 years, since my first introduction to Junos back in early 1999 — as such, I am thrilled to join the ranks of my esteemed peers, whom I sincerely consider to be the best in the industry. A special thanks goes out to Andy Green, Director of Education Services Americas at Juniper Networks for nominating me and to the rest of the Juniper Ambassadors who apparently endorsed that nomination with a resounding yes. I look forward to seeing and collaborating with all of you on the J-Net Forums!
Juniper took a big step forward in rounding out their certification programs by announcing a new Design Training and Certification curriculum, focusing on best practices and techniques that can be used across the spectrum of network architecture and design. Slated to be included in this program are also technologies around software-defined networking (SDN) and network functions virtualization (NFV).
Not a day that goes by since having passed the JNCIE-SEC exam that I don’t receive an inquiry in one form or another regarding how I prepared for the exam. It seems that there is an incredible amount of interest in this exam, especially from all those die-hard ScreenOS folks that are now converting to Junos. So instead of constantly repeating myself, I figured I’d just put it up on the blog so others can benefit (leaving me more time to do other things, ‘heh).
In our previous article, we looked at using apply-groups to alter all the security policies uniformly on an SRX device such that they would all have an implicit logging statement. And while this is fine for all existing policies, it doesn’t log traffic which doesn’t match any explicitly defined security policy.
The reason for this is due to the fact that in Junos, traffic which doesn’t match an explicitly defined security policy matches against the default-deny policy. However, given the fact that the default-deny policy is implicitly defined, apply-group configurations are of little benefit as apply-groups can only be inherited by those elements which have been explicitly defined.
