In 2008/2009 I studied for an Advanced Diploma in Network Security, and an Advanced Diploma in Telecommunications Networks. The study was at the Cisco Academy in Meadowbank, and also included the CCNP v5.0 – BSCI, BCMSN, ISCW, and ONT; and modules from the CCSP – SNPA, and SNRS. Unfortunately I never actually got around to sitting the CCNP exams, and wish to do so now.

I’ve decided to go through all my old lab manuals and redo each lab in GNS3, and of course, post notes for those labs here. While the CCNP has been updated to v6.0, a lot of the lab work is the same. Any knowledge gaps I will fill as I go. Some labs that require switch work (most of BCMSN) will either be done in GNS3 using a 3700 IOS and a 16port switch module; else, I will be using actual hardware.

I’ve added a Cisco labs category to my category list for this purpose. I may add more categories (such as EIGRP, OSPF, etc) in the future.

“The man in black fled across the desert and the gunslinger followed” — Stephen King; The Dark Tower. How I wish I could have been so resolute in my pursuit to be part of the blogosphere; a goal I’ve had on my check-list for so long, but a task that my ever prevailing procrastination has always disallowed. Never did it seem like I’d actually be writing this post.

I registered the domain name “null-security.com” in 2006 when I first started dabbling in the field of information security (in particular, web-hacking). A discussion took place between myself and a couple of other up-and-coming “hackers” on irc.2600.net #somerandomchannel, that it would be a something of a good idea to publish our thoughts, findings, and research for reasons that would be beneficial to ourselves and others in the form of a blog. In retrospect, it was a good idea. In retrospect, I should have started it then.

There is reason for my procrastination, but in all truth, it was more excuse than sound reason. You see, I’d originally started a blog not much earlier than the discussion took place; I had great plans and high hopes. At the time, I was pretty stuck into PHP coding and had created my own blogging platform–albeit, a very limited blogging platform–and wanted to continue developing that in conjunction with related blog posts.

Unfortunately I ran into some troubles with my host at the time (DreamHost) who didn’t like the idea of hosting anything remotely related to hacking. They removed my account without warning; wiping my profile and everything hosted by them- including my blogging platform. It was quite a blow and I never quite regained the motivation to start over. Backing up my code would have been a great idea, but hindsight is 20/20 and a hard lesson is a lesson learned.

With the hundreds of FOSS options for blogging, I don’t understand why I just didn’t pick one up and continue with that. I guess I always thought it best practice to develop your own blogging platform if a integral part of your blog was to be about development. Fortunately I’ve left that mentality behind and picked up WordPress as my platform. It’s so feature-rich it makes it difficult to warrant building your own.

Four years on from the tragic day my ~ directory was rm -rf’d by an over-security-zealous host, I’ve moved on from the trouble-making black hat I was, to a network engineer and security enthusiast. I’m currently employed by a large government body where I deal with a range of issues from building multi-layered switched networks, to applying relevant IDS rules, monitoring network traffic, and ensuring that the network is performing at an optimal state, even penetration testing in-house developed applications.

I still get excited when I find an unknown hole in a popular CMS. I still get excited when I get to play with new networking equipment. I still get excited when I get to plan and perform a penetration test at work; and get paid to do so.
