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….

Tips for getting started in information security
SOURCE:http://www.leune.org/blog/kees/2008/10/-tips-for-getting-started-1.html
I regularly get questions of students who expect to graduate soon asking what they need to do to get started in the information security field. Unfortunately, I cannot give a straight unambiguous answer to that. What I can do is start a thought process for that student. In the end, they will have to do the work.
Become experienced
Get a job that sounds like it is relevant to security. It does not actually have to be dead-on, but when a potential employer reads your resume, she must feel some sort of connect. Unfortunately, most security jobs ask for experience, so that is exactly what you need to get.
Most likely, the easiest way to do so is to find a job for a large consultancy organization and make it clear to them that you are willing to work hard, travel when necessary, and add value to their organization. At the same time, don't let your employer ever doubt that you are going to become an information security specialist.
Focus
Information security professionals are service providers and you need to figure out if you want to become a consultant that comes in to do a job, or if you want to work for the organization that uses your services. Make up your mind if you want to become a product specialist. Early in your career, consulting is not a bad way to go, since that will expose you to different industries, different problems and different working cultures.
Deciding if you want to work in a specific industry, or in a particular geographic area is also part of making the focus decisions. I know people who decided very early on that they wanted to work for a specific organization and they had their career plan centered around that goal. The same is true for geographical areas. If you decide that you want to work in the New York City, you will probably end up in the financial services industry or in fashion. If you are on Long Island, start learning about medical services. Other areas have similar industry focuses.
Specialize
Think hard about the area in which you want to specialize and work towards that. Depending on the direction in which you want to move, you will need to spend just about every waking hour doing "stuff" with security.
If you chose your direction to be penetration testing, find a pentesting job. When you come home, start doing stuff in your own lab. If you want to become an incident responder, look in that area and start dabbling with forensics-type stuff on your own time. If you want to become an information security manager, try to get some leadership experience. If you want to become an application security specialist, start coding.
Certify
There is much discussion surrounding the actual value of a security certification, but the basic fact is that employers will look for something that can distinguish you from the rest. Not having a certification is definitely a distinguishing factor, but it may not be what you want.
When choosing your certifications, keep your specialization goals in mind. It is useless (and may even work against you) to pursue vendor-specific certifications if you want to do something with a broader scope. The opposite is also true-- striving to pursue a general certification when you want to be a niche specialist is also pointless.
Branding
Make yourself visible: become a member of security organizations and go to chapter meetings. Attend as many events as you can, even if they are not in your focus area. At worst, you will spend an afternoon thinking about why the topic is not relevant to you (also valuable), and at best you meet your next employer.
If there are no chapters, start one. If you can afford it, begin visiting security conventions and conferences, reading (and comment on) blogs, maybe even start your own blog, join dedicated chat rooms and online forums, jump on twitter, linkedin, etc. Set up your own web site; don't be afraid to oversell yourself, but never lie. As an information security professional, your personal reputation and credibility is everything. The information security field is young, highly dynamic and the good people in the field form a close community. Associate with the right people.
Plan
Finally, come up with a career plan. That plan will be perfect nor complete when you make it first, but continue to update it as your expectations of the future take on more concrete form. Write down that plan on paper (not just as a file on a computer-- paper is more convincing!)
No employer expects that you spend your entire working life with them, but job-hopping every few months will come back to bite you. It creates the impression that you are not reliable, because you are not going to be around long enough to invest in. Plan to stay in a position for at least a year.

Ideal Skill Set For the Penetration Testing
SOURCE: http://resources.infosecinstitute.com/ideal-skill-set-for-the-penetration-testing/
Based on questions I’ve gotten over the years and specifically in class, I’ve decided that we need to address some basic skills that every penetration tester should have. While we can’t realistically expect everyone to have the exact same skill set, there are some commonalities.
1. Mastery of an operating system. I can’t stress how important it is. So many people want to become hackers or systems security experts, without actually knowing the systems they’re supposed to be hacking or securing. It’s common knowledge that once you’re on a target/victim, you need to somewhat put on the hat of a sysadmin. After all, having root means nothing if you don’t know what to do with root. How can you cover your tracks if you don’t even know where you’ve left tracks? If you don’t know the OS in detail, how can you possibly know everywhere things are logged?
2. Good knowledge of networking and network protocols. Being able to list the OSI model DOES NOT qualify as knowing networking and network protocols. You must know TCP in and out. Not just that it stands for Transmission Control Protocol, but actually know that structure of the packet, know what’s in it, know how it works in detail. A good place to start is TCP/IP Illustrated by W. Richard Stevens (either edition works). Know the difference between TCP and UDP. Understand routing, be able to in detail describe how a packet gets from one place to another. Know how DNS works, and know it in detail. Understand ARP, how it’s used, why it’s used. Understand DHCP. What’s the process for getting an automatic IP address? What happens when you plug in? What type of traffic does your NIC generate when it’s plugged in and tries to get an automatically assigned address? Is it layer 2 traffic? Layer 3 traffic?
3. If you don’t understand the things in item 2, then you can’t possibly understand how an ARP Spoof or a MiTM attack actually works. In short how can you violate or manipulate a process, if you don’t even know how the process works, or worse, you don’t even know the process exists! Which brings me to the next point. In general you should be curious as to how things work. I’ve evaluated some awesome products in the last 10 years, and honestly, after I see it work, the first thing that comes to my mind is “how does it work”.
4. Learn some basic scripting. Start with something simple like vbs or Bash. As a matter of fact, I’ll be posting a “Using Bash Scripts to Automate Recon” video tonight. So if you don’t have anywhere else to start, you can start there! Eventually you’ll want to graduate from scripting and start learning to actually code/program or in short write basic software (hello world DOES NOT count).
5. Get yourself a basic firewall, and learn how to configure it to block/allow only what you want. Then practice defeating it. You can find cheap used routers and firewalls on ebay, or maybe ask your company for old ones. Start with simple ACL’s on a router. Learn how to scan past them using basic IP spoofing and other simple techniques. There’s not better way to understand these concepts than to apply them. Once you’re mastered this, you can move to a PIX, or ASA and start the process over again. Start experimenting with trying to push Unicode through it, and other attacks. Spend time on this site and other places to find info on doing these things. Really the point is to learn to do them.
6. Know some forensics! This will only make you better at covering your tracks. The implications should be obvious.
7. Eventually learn a programming language, then learn a few more. Don’t go and by a “How to program in C” book or anything like that. Figure out something you want to automate, or think of something simple you’d like to create. For example, a small port scanner. Grab a few other port scanners (like nmap), look at the source code, see if you can figure any of it out. Then ask questions on forums and other places. Trust me, it’ll start off REALLY shaky, but just keep chugging away!
8. Have a desire and drive to learn new stuff. This is a must; It’s probably more important than everything else listed here. You need to be willing to put in some of your own time (time you’re not getting paid for), to really get a handle on things and stay up to date.
9. Learn a little about databases, and how they work. Go download mysql, read some of the tutorials on how to create simple sample databases. I’m not saying you need to be a DB expert, but knowing the basic constructs help.
10. Always be willing to interact and share your knowledge with like minded professionals and other smart people. Some of the most amazing hackers I know have jobs like pizza delivery, janitorial, one is a marketing exec, another is actually an MD. They do this strictly because they love to. And one thing I see in them all is their excitement and willingness to share what they’ve learned with people who actually care to listen and are interested in the same.
These things should get you started. Let me know if you have questions or comments.
