CCIE Security: IPSec VPN Overview (IKEv1)

In this post, I'm going to go over a high level explanation of VPNs and specifically IPSec. This is going to be the first in a series of VPN posts focusing on the various types of VPNs one might see on the CCIE Security lab or on the job. I think it's important to have this overview because as you configure IPSec VPN or troubleshoot it, it'll help you to know what's going on under the covers of that configuration. 

Integrating ISE with Splunk for Reporting

This post is going to be a bit different. I'm configuring Splunk in my lab currently for reporting and as I go through it, I'm going to detail my configurations here. I am going to use Splunk to aggregate my ISE logs to it. In order to do so, we're going to have to install the Spunk for Identity Services (ISE) app onto Splunk. Before starting, please download the app

Installing Splunk

I'm currently adding Splunk to my lab so as I'm going through the configuraitons, I'm going to list out what I do here as a series of blog posts. Splunk is a pretty power SIEM that works to aggregate and correlate data across your network and security tools. If you ever wanted to try it out for free, go to and you should be able to download it for free for use up to a certain point. The nice thing about Splunk is that there are tons of free pre-built apps and dashboards for multiple vendors which you can download

State of the IT field: Demand is high for SKILLED engineers

I've been thinking about writing this post all week and decided to wait until I processed my thoughts a little more before I wrote it out. There's a lot of fear, uncertainty and doubt that's been going on in the field for years and here are some of repetitive questions I tend to hear on Linkedin, Techexams and other social media: 

  • Is it worth going into networking/getting a CCIE/etc if SDN is going to take over? 
  • There's so many engineers out there, why do companies choose to hire H1Bs? 
  • Do I have to worry about my job getting outsourced to another country? 
  • Do I have to worry about H1Bs taking my job?
