A "job in Information Security" is a rather ambiguous statement. With today's technology environments, security is becoming more and more specialized. I agree to a point with a previous responder that certs are only an indication of an area of study. It really does not prove ability in a real-time situation. But, studying in your preferred area is VERY important.
CISSP is a great place to start. Many places will only hire someone with certs, so that is where the importance of certifications lie.
My preferred interest area is in digital forensics. More specialized, less in demand, but I find it a lot more interesting, personally.
I think the most important thing is to never stop studying. This is an ever changing industry. The techniques evolve very frequently, so our duty as IT Professionals (in all areas of IT, not just infosec), is to never stop learning.
One of the most common questions I get asked is “How can I become an information security professional?”. These days, it seems that a ton more people want to be in the “business” of information security. I get the question so often, I thought I would write this post as a quick and easy way to respond.
Are You Serious?
The first response is a “gut check”. Are you serious that you want to be an infosec person? Do you even know what you are asking? My suggestion is 2 steps. Number 1, read a basic information security guide (not Hacking Exposed or something on an aspect, but something more general like the ISO standards). Number 2, invest in your career option enough to buy a few coffees or beers and ask a couple of security folks you know of and trust to sit down, one on one with you for an hour chat. Talk about that person’s career, what day to day security work is like in their experience and what they think about your ideas for moving forward. If you can’t or won’t invest in these basic steps, then quit now and choose another career path. Security work is all about research, reading, guidance, networking and conversations with other humans. If you can’t do these toddler steps, then forget running with the big dogs and find another pack.
Get Serious, Quick!
Step 1: Knowledge boost: Start to read every single security book you can find. Listen to podcasts, read web sites, subscribe to mailing lists. Read RSS feeds.
Step 2: Find a way to contribute: Work on an open source security project. If you can’t code, then write the documentation or contribute to testing. Start a website/blog and start to aggregate or gather other security news. Wax poetic on what you think of certain topics. Think of this part as turning knowledge into wisdom. It is where the rubber meets the road and where you will encounter some pain, humiliation and grief, but it is another form of “gut check” to make sure you are ready to be in infosec.
Step 3: Build a lab & practice security skills: Build a lab. Make it out of old hardware, virtualization systems, Live CD’s, etc. Then hack stuff. Secure stuff. Apply settings, scenarios, access controls. Shop at eBay, garage sales, thrift stores or Walmart to cut the cost down. Be creative and pragmatic, both are essential security skills.
Step 4: Brand yourself: Once you have some wisdom and insight, then update your resume. Build a personal brand. Read books by Seth Godin and Guy Kawasaki to learn to do this. Learn how to separate yourself from Joe Six-Pack and how to turn your security experiences with the above projects into valuable differentiators that open doors for you to get that job you wanted. Is it work? Yes. Is it hard work? Yes. Does it take time? Heck, yes. Is it worth it? If you get what you really want, heck yeah!!!!
It’s OK to Turn Back
If, at any point during the above steps, you decide you are not interested enough to continue, then don’t. Security is tedious, hard work. Most of it is COMPLETELY NOT SEXY and has nothing to do with Swordfish, Hackers or the Matrix, no matter how much you want to be Neo, Cereal Killer or Angelina Jolie. Security is mundane, boring, full of science, analysis and research. If you want to be great at it, you also need to understand business, marketing, math, human resources, education, more marketing, sales, basic programming, public speaking, more marketing and oh, yeah, more marketing. Why so much marketing? Because, believe it or not, people need to be sold on being secure. That is the largest irony of the job. You have to not just identify how to make them secure AND teach them how to be secure, BUT you ALSO have to SELL them on the idea that security is worth their investment of time, energy and resources. It’s not that they don’t want to be secure, it’s that humans are REALLY BAD AT MAKING RISK DECISIONS. Keep this in mind as your security career progresses. It is a handy meme.
Are there Shortcuts?
Maybe, if you wanna be average. More than likely not, if you wanna be truly GREAT at what you do. Everything in life has a price. The good, the bad and the security career. Paying that price is a part of the reward, you just might not know it yet. Pay the price. This is one system you really don’t wanna “hack” to get at the “easy way”, it makes for a lot of pain down the road when you look foolish.
What About Certifications?
I am not a believer in certs. I have never made any secret about my position. I DO NOT HAVE MY CISSP NOR AM I LOOKING TO EVER HAVE ONE. Certs are NOT a good measure of experience, work ethic or intelligence. They represent all that I hate about the security industry and the idea of doing the minimum. This is not to say that you should not pursue them or that they are not valuable, it is just my belief that the IT industry puts way too much stock in certs. They believe that most every CISSP is a real “security person” and knows their stuff. I have met plenty who do not. I have met plenty who I would not let manage my security. I have met some that I would, as well. The same goes for all certs (MCSE, CSA, etc.). Certs are just a BASIC qualification mechanism, no more, no less. Experience and what you have done in the past speak volumes more to me, and anyone I would want to work for or with, than a cert. Period.
I hope this answers those basic questions about how I think you should move toward being a security professional. I hope you do choose security as a career, if you are willing to invest in being great at it. The world needs more great security people, but we also need less inadequate security professionals. The industry has its charlatans and fakes, but it also has some of the best people on the planet. This industry has been good to me for almost two decades. I have met and made friends with some of the most talented, fascinating and warm people in the world. I am very blessed and very grateful. I hope you will be too. Buy me a cup of coffee if you want to talk more about it. I promise to try and help you figure out if this is the way you want to go, if you are willing to invest in yourself first BEFORE you seek my input. More than likely, you will find the same to be true for other security experts too. They just might like cheaper coffee than I do….
