After putting it off until the very last moment, I finally wrote and passed the Certified Wireless Security Professional (CWSP) PW0-204 exam. This was important since it had been almost 3 years since I passed the CWSP (PW0-200) exam and my credentials were set to expire on the 25th of June. Crisis averted! With the exam out of the way, I thought it would be worthwhile to share some thoughts on my experiences while preparing for it.
In no specific order, here are a few things I found very interesting about my time studying for PW0-204:
- Wireless security was much less complicated 3 years ago. When I took the PW0-200 exam, I didn’t have to know anything about 802.11n, 802.11k, 802.11w, or 802.11r. All of these, now ratified, IEEE standard amendments come with their own set of additional security settings and concerns that must be taken into consideration when securing a WLAN. Continuing to educate yourself and staying on top of the latest industry developments is the easiest way to ensure that a certification’s body of knowledge doesn’t leave you behind.
- Experience in the field helps immensely with this exam. When I first wrote the PW0-200 exam, 3 years ago, I had a great interest in the subject but very little real-world WLAN experience. This time around, after living and breathing WLANs for 3 years, I found I was able to quickly skim or review a lot of the CWSP Study Guide since I deal with 802.1X/EAP, PKI, and WIDS/WIPS solutions quite frequently in my role as a security consultant. In my opinion, the CWSP certification is a great example of an exam that goes beyond ‘textbook studying’ and really tries to incorporate lessons that can only truly be learned through hands-on experience. Certifications like that rock because they signify practical/useful knowledge instead of just the ability to memorize answers for a test.
Keeping my existing CWNA and CWSP credentials was just stop number one on this journey. With that out of the way, I’m now beginning my assault on the Certified Wireless Network Expert (CWNE) designation. Last time I check there were less than 100 CWNEs globally so it’s definitely going to be a challenge. I have to pass both the CWDP and CWAP exams first. Wish me luck and I look forward to posting my thoughts and insights on my next exam this summer.
