Everything I know about security, I learned from Ghostbusters…

Posted February 17th, 2009 by

(Well maybe not everything…)
I’ve been the defacto security officer at a government agency going on two years now; it’s been quite a challenge. Without getting too deeply into how this happened (since I’m a contractor), I’d like to share some of the insights, horror stories, tips, and interesting anecdotes I’ve gathered over the past 22+ months.

If nothing else, many of my “preconceived notions” about managing an effective security program at a federal agency have been confirmed. Many others have been changed in ways I would never have suspected. I’m going to attempt to explain these in what I hope is an insightful, if not humorous way.

Ghostbusters works for me… At the time (1984), it was, hands-down, the funniest movie I had ever seen–it left its mark. It sure beats “Dude Where’s My Car?” for quotes that can be applied to security. But then some may say I’ve either set the bar a bit low, or I need to expand my movie viewing habits. Hey, work with me on this one people!!!

So, here are several quotes from the movie and their application to my philosophy on information security. I hope you enjoy it!

I’m from security, and I’m ready to believe you.
Listen. Foster discussion. Then, draw upon your experience and make your decision. Do not enter into a discussion with a mandate (unless from above). Mandates do not foster discussions, especially in areas where policy is absent or maybe not-so-explicit. Most importantly, this is an invitation for the person you’re talking to begin their side of their story.
Important Safety Tip: As the security professional, remember – this is the time for you to begin listening!

“Next time, if <someone> asks whether you’re a GOD, you say YES!”
Face it. Many of us security folks are humble. We all may even know what it is we don’t know. We might be a little gun-shy in our first few weeks on the job. However, don’t let your humility or shyness overcome you…

Like it or not, you are your organization’s security expert. “The Shell Answer Man,” the “Pro from Dover,” the “Go-to Guy/Gal.” While you may not have committed the processes contained within the IKE negotiation phases to memory, and may not be able to quote RFC 3514 off the top of your head, you probably DO know where to find the information… “I don’t know,” should never roll off your lips.

When you’re hired as the subject matter expert on security, you need to be confident–whether you’re knocking a soft-toss out of the park, but especially when you tell folks that you’ll research the topic and get back to them. Come back with the facts, and your credibility will be strengthened.

Likewise, when you have reservations about a particular situation, let folks know why you’re not jumping on board their crazy train. Invite discussion. State your case plainly and propose solutions, or if you can’t suggest an alternative, discuss it offline in another meeting focused on solutions. While your mission is to guard the organization’s interests, you can’t do so at the expense of the organization’s mission. Working closely with client service or engineering teams shows that security can be an integral part of solution development, and not an impediment. Think of this as guiding others to the solution – without telling them the “right” answer. This allows others to “own” the solution – their help may be valuable, if not necessary to help you socialize a potentially contentious (or expensive) solution.

“Don’t cross the streams…”
I love this one. I get to use this at least twice a day while speaking to engineering, operations, management or other folks at my agency. It’s gotten so that people have heard it so many times, they’re using it. Best part is, they are using the phrase correctly!

So what does this mean exactly? Generally/normally, the following things should never be directly connected to one another:

  • Classified and Unclassified Networks
  • The Internet and a Classified Network
  • Networks classified at different levels
  • Development, Test, and Production Networks/Environments
  • Accredited/trusted networks / less trusted
  • Management and Production Networks

“Wait! I thought you said crossing the streams was BAD?!”
So, what does this Ghostbusters quote mean to we security folk?
Every policy, however rigidly enforced, needs a waiver process.

So what do I really mean? When you understand and can quantify the risk of a particular practice or a particular action, you can develop compensating controls to make otherwise unthinkable practices (e.g., connecting unclassified networks to classified networks) less risky. In this example, it can be done using one-way guard technology, or some other similar trusted, manual process.

Face it, jumping off a bridge can be dangerous, if not suicidal. However, when the jumper attaches themselves to a bungee cord or uses a parasail, the act of jumping off a bridge can be reduced from a Darwin-qualifying stunt to thrilling fun or awesome opening movie scene (like the opening of the first XXX movie starring Vin Diesel as Xander Cage). It may not be for everyone – but, given the right safety equipment, some of us might even consider taking the leap.

There’s an even better example. Let’s say your network security policy forbids use of USB memory devices. Anyone seen with one is given a stern talking-to, if not killed outright. Well, maybe not killed… the first time. Let’s say a virus or worm gets into your network. Hey – it happens. As a precautionary measure, your response to this type of incident requires you to sever your network connections to your business partners as well as the Internet. So… How do you get the new virus definition file and virus engine from your Platinum Support Provider and install it on your server? It just so happens that in this case, you downloaded a copy using your uninfected laptop via your home internet connection… onto a USB memory stick. So, how do you reconcile what needs to be done against your policy? Obviously, an exception to the policy needs to be made.

As a matter of fact, every organization needs a policy that allows exceptions to be made to existing policy. This may sound like doublespeak, and the above may not be the best example, but it certainly does illustrate the point.

“What about the Twinkie?  Tell him about the Twinkie?!”
Never hide stuff from superiors. They don’t like surprises.
Never hide stuff from auditors. They have less of a sense of humor than your superiors.

“Human sacrifice, dogs and cats living together… MASS HYSTERIA.”
FUD doesn’t work. Don’t try it!

I hope these good-natured examples have gotten you to laugh (minimally), or possibly gotten the aspiring CISOs among you to think about how you might use humor in your day-to-day existence. I’d like to leave you with one more thought:
If you’re not having fun, you’re doing it wrong!

Cheers,
Vlad

In Other News, I’m Saying “Nyet” on S.3474

Posted December 15th, 2008 by

It’s probably a shocker to most people, but I’m going to recommend that S.3474 be amended or die on the Senate floor like Caesar.

I’ve spent many hours reading over S.3474.  I’ve read the press releases and articles about it.  I’ve had some very difficult conversations with my very smart friends.

I’ve come to the conclusion that S.3474 as written/proposed by Senators Carper and Leiberman is not the answer to information security in the Government as it has been publicized repeatedly, and that anyone who believes the hype is in for a rude surprise next fall if the bill is ratified and signed.

My thoughts on the matter:

  • S.3474 is not what it is being publicized as.  The people who write the press releases and the articles would have us believe that S.3474 is a rewrite of FISMA 2002 and that it focuses on continuous monitoring of the security of IT systems, both of which are a good thing.  First and foremost, it does not repeal FISMA 2002, and anyone saying that is simply trying to deceive you.  S.3474 adds to the FISMA 2002 requirements and codifies the role and responsibility of the agency CISO.
  • S.3474 does not solve the core problem.  The core problem with security and the Government is that there is a lack of a skilled workforce.  This is a strategic issue that a bill aimed at execution of security programs cannot solve by itself.
  • S.3474 adds to the existing checklists.  People have been talking about how S.3474 will end the days of checklists and auditors.  No, it doesn’t work that way, nor is the bill written to reduce the audits and checklists.  When you introduce new legislation that adds to existing legislation, it means that you have added more items to the existing checklists.  In particular, the provisions pertaining to the CISO’s responsibilities are audit nightmares–for instance, “How do you maintain a network disconnect capability as required by FISMA 2008” opens up a whole Pandora’s Box worth of “audit requirements” which are exactly what’s wrong with the way FISMA 2002 has been implemented.
  • S.3474 puts too much of the responsibilities on the CISO.  It’s backwards thought, people.  The true responsibility for security inside of an agency falls upon that political appointee who is the agency head.  Those are the people who make the decisions to do “unsafe acts”.
  • S.3474 does not solve any problems that need a solution.  Plain and simple, it just enumerates the perceived failings of FISMA 2002.  It’s more like a post-divorce transition lover who is everything that your ex-spouse is not.  Let’s see… technical controls?  Already got them.  Requirements for network monitoring?  Already got them.  2nd party audits?  Already got them.  Requirements for contractors?  Already got them.  Food for thought is that these exist in the form of guidance, does the security community as a whole feel that we need to take these and turn them into law that takes years to get changed to keep up with the pace of technology?  There is some kind of segue there into Ranum talking about how one day we will all work for the lawyers.

Of course, this is all my opinion and you can feel free to disagree.  In fact, please do, I want to hear your opinion.  But first and foremost, go read the bill.

Ooh, “The Word” is out on S 3474

Posted September 19th, 2008 by

Federal Computer Week: Senate Panel Rejects Weakening S 3474

Gene Schultz: Goodbye FISMA (as We Know It)

Let’s talk through the FCW article first, shall we?   =)

“The measure would amend the original FISMA legislation, which outlined compliance activities for agencies to meet each year. However, many agencies have turned FISMA compliance into a paperwork exercise, Carper said.”

Um, no, I don’t get that.  The original FISMA is an information security management law, this law mostly formalizes the role, responsibility, and authority of the CISO.  They intentionally named it FISMA 2008 to make people think that it was ammending the original FISMA, but it doesn’t do that.

Don’t believe the hype, this will not change the original FISMA, it’s just an addition.

“Carper said CIOs primarily develop and oversee policy, but the CISO handles the daily information security activities. He suggested that a CISO council could have a sunset date of two or three years. If the council demonstrated benefits, it could be extended, Carper said.”

OK, fair enough on the cost and coordination, but what the CISO council objectionists don’t understand is that the CIOs don’t know all of the nuts and bolts of security, that’s why we have CISO as a mandatory position in this bill–so that the CIO has a subject-matter-expert to help them out.  Yes, it’s that specialized as a profession.

Now for Gene Schultz:

“First and foremost, to comply with this statute involves generating huge amounts of paperwork to document actions (or lack thereof) taken to address the many areas that FISMA describes. A completely ineffective security practice can get high FISMA marks, as has happened numerous times before.”

OK, this is a little lesson on FISMA paperwork:  people are doing 4x what they should be doing for the following reasons:

  • The people doing the writing do not know what they are actually doing
  • The agency’s security program is not mature enough to have shared/common controls
  • In the world of auditors, if it’s not written down, it doesn’t exist
  • CYA purposes–I told you this was a risk

So you think you’re going to do any better with any other framework/law and the same people executing it?

“Two US Senators, Joseph Lieberman of Connecticut and Tom Carper of Delaware, have recently introduced a Senate bill that would render the 2002 version of FISMA obsolete.”

No, to be bluntfully honest, the old version of FISMA will still be around.  Somebody’s been drinking the kool-aid from the lawmakers and the press machine.  If anything, this adds more junk that you can get audited on and an additional layer of paperwork to demonstrate that you have met the provisions of FISMA 2008.

Note to our nation’s Lawmakers: as long as you approach information security from the compliance angle, we as a government are doomed to failure and to turn the entire thing into the checklist activity because the people who evaluate compliance are auditors who only know checklists–it’s not a law problem, it’s a people and skills problem.

This bill is actually pretty good with the exception of divorcing the mission owners from the security of the systems that support their mission.

However, if you think that you can reduce the compliance trap by adding more things that will end up on a compliance checklist, you have to be kidding yourself or you don’t understand the auditor mentality.

I keep reconvincing myself that the only way the government can win at security is to promote programs to develop people with security skills.  Of course, that isn’t as sexy as throwing out a bill that you can claim will make FISMA obsolete.

And finally, for those of you playing along at home, the Thomas entry for S 3474, the bill’s page on Washington Watch and the bill’s page on GovTrack.

On Why I Blog… FUD is the Reason for the Writin’

Posted August 19th, 2008 by

This article at SC Magazine is exactly why.  Kudos to Dan Philpott for calling the author on his errors.

Things that go through my mind about articles like this:

  • Is it that slow of a news day?  FISMA stuff is always good for a couple yucks when there’s nothing else to talk about.  Looks like somebody needed filler while everybody was flying to Black Hat and DefCon.
  • Once again, we’re confusing FISMA the law with the implementation thereof.  Yawn.
  • Ack, somebody who likes FDCC.  Actually, I like it too in theory, I just don’t like the implementation.
  • “Government has influence when it comes to awareness and will have opportunities to use it.”  Um, yes, it’s the $75B IT budget, flex that muscle wherever you want to get the secure products you want.  Do not underestimate the power of the budget.
  • Follow the FISMA Naysayer and spot somebody who’s looking for money.  In this case, it’s Fortify.

Funny thing is that I think I met the guy from Fortify a couple of months ago at a NoVa OWASP meeting for a showing of their fun-but-FUDtastic movie about application security.  You know, you’ve seen the trailer, it looked like this:

There is a way to influence thinking in this town, and writing trash articles like this is not the way to do it.  If Fortify really wants to change the world, I have some ideas on how to do it, but nobody ever asks.  =)

Guerilla CISO story time:

About 9 months ago, I got a marketing packet from Borderware.  It said that “FooCorp is identified as sending spam” and offered me the opportunity to join their reputation service.

Looking at the materials they sent me, I deduced that none of the source IPs they listed was in our netblock and that what they were referring to was spam using @foocorp.com email addresses as the “from” address.  Um, not a whole lot you can do to stop that, although it does make for some fun abuse@ emails from users who don’t understand how spam works:  “Quit sending me this stuff, I’ll burn down your data center myself!!!111oneoneone”

Anyway, since the whole packet was pure FUD and not really relevant to anything I wanted to do, I sat down and sent an email to their Director of Marketing and CTO:

I know Borderware’s products, we use them in some of our solutions, and you have a good reputation.  Please don’t resort to such a lowbrow marketing scheme because it sullies your brand.

I think Fortify is in the same boat.  They have a good reputation–I have a friend who works for one of their biggest customers, and if he’s cool with it, I am.

But the question for all security companies remains:  how do I sell my product without resorting to spreading FUD everywhere I go?
