Old Saint NIST: Ho Ho Hold on, what’s this?

Posted December 13th, 2009 by DanPhilpott

Every once in a while an opportunity presents itself to affect some real change in federal information security practice.  Now is such a time.  A slew of new NIST documents are being released between now and April.  These are the core NIST documents that describe how to satisfy FISMA.  They include NIST SPs 800-30 Revision 1, 800-39, 800-37 Revision 1 and 800-53A Revision 1. That’s where you come in.

The documents define what federal government practice will look like in the coming years.  If they are flawed then the practice will be flawed.  To prevent stupidity from leaking in when nobody is looking NIST releases the documents as drafts so everyone gets a chance to eyeball them.  First you eyeball, then you comment.  They look at the comments and they fix the flaws.  Fix the flaws now and you don’t live with them later.

The most important document in draft right now is the NIST Special Publication 800-37 Revision 1.  This document describes the central processes involved in the authorization of information systems that support the federal government.  Notice I didn’t say Certification and Accreditation?  That’s because C&A is deader than a sheep at a wolf convention. Want to know what replaces it?  Pick up a copy of NIST SP 800-37r1 FPD, give it a read and send in your comments.

Better yet, consider joining a formal document review process.  I’m leading a team of hale and hearty volunteers at OWASP in a NIST SP 800-37r1 FPD review and we’d love to have you come join the fun.   We’re on a tight schedule so now is the time to act.

Time is short, the comment period for NIST SP 800-37 Revision 1 FPD ends on December 31st, 2009.

NIST Framework for FISMA Dates Announced

Posted April 10th, 2009 by rybolov

Some of my friends (and maybe myself) will be teaching the NIST Framework for FISMA in May and June with Potomac Forum.   This really is an awesome program.  Some highlights:

  • Attendance is limited to Government employees only so that you can talk openly with your peers.
  • Be part of a cohort that trains together over the course of a month.
  • The course is 5 Fridays so that you can learn something then take it back to work the next week.
  • We have a Government speaker ever week, from the NIST FISMA guys to agency CISOs and CIOs.
  • No pitching, no marketing, no product placement (OK, maybe we’ll go through DoJ’s CSAM but only as an example of what kinds of tools are out there) , no BS.

See you all there!

Certification and Accreditation Seminar, March 30th and 31st

Posted March 13th, 2009 by rybolov

We’ve got another good US Government Security Certification and Accreditation (C&A) Seminar/Workshop coming up at the end of March with Potomac Forum.

Graydon McKee (Ascension Risk Management and associated blog) and Dan Philpott (Fismapedia Mastermind and Guerilla-CISO Contributor) are going to the core of the instruction, with a couple others thrown in to round it all out.  I might stop by if I have the time.

What we promise:

  • An opportunity to hear NIST’s version of events and what they’re trying to accomplish
  • An opportunity to ask as many questions as you possibly can in 2 days
  • Good materials put together
  • An update on some of the recent security initiatives
  • An opportunity to commiserate with security folks from other agencies and contractors
  • No sales pitches and no products

See you all there!

The 10 CAG-egorically Wrong Ways to Introduce Standards

Posted February 20th, 2009 by DanPhilpott

The Consensus Audit Guidelines (CAG) appear, at this point, to be a reasonable set of guidelines for mediating some human threats. I’m looking forward to seeing what CAG offers and have no doubt there will be worthwhile and actionable controls in the document. That said, there are significant reasons approach CAG with skepticism and assess it critically.

The motivation for CAG is described in a set of slides at the Gilligan Group site. It starts with a focus on what CIO’s fear most: attacks, reduced operational capability, public criticism, data loss, etc. Then it rightly questions whether FISMA is adequately addressing those problems. It doesn’t and this is the genesis of the CAG.

Unfortunately CAG subsequently develops by pairing this first valid premise with a set of false premises.  These propositions are drawn from slides at gilligangroupinc.com, attributed to John Gilligan or Alan Paller:

  1. All that matters are attacks. The central tenet of Bush’s Comprehensive National Cyber Initiative (CNCI) is adopted as the CAG theme: “Defense Must Be Informed by the Offense”. CAG envisions security as defense against penetration attacks. As any seasoned security practitioner knows, attacks are a limited subset of the threats to confidentiality, integrity and availability that information and information systems face.
  2. Security through obscurity. CAG seems to have taken the unspoken CNCI theme to heart too, “The most effective security is not exposed to public criticism.” Since its very public December 11th announcement no drafts have been made publicly available for comment.
  3. False dichotomy. CAG has been promoted as an alternative to the OMB/NIST approach to FISMA. It isn’t. An alternative would target a fuller range of threats to information and information system security. CAG should be considered a complement to NIST guidance, an addendum of security controls focused on defense against penetration by hackers. NIST has even acted on this approach by including some CAG controls into the 800-53 Rev. 3 catalog of controls.
  4. There is too much NIST guidance! This is the implication of one CAG slide that lists 1200 pages of guidance, 15 FIPS docs and the assorted Special Publications not related to FISMA as detriments to security. It’s like complaining that Wikipedia has too many articles to contribute to improved learning. Speaking as someone who scrambled to secure Federal systems before FISMA and NIST’s extensive guidance, having that documentation greatly improves my ability to efficiently and effectively secure systems.
  5. NIST guidance doesn’t tell me how to secure my systems! NIST’s FISMA guidance doesn’t step you through securing your SQL Server. The Chairman of the Joint Chiefs also doesn’t deliver your milk. Why not? It’s not their job. NIST’s FISMA guidance helps you to assess the risks to the system, decide how to secure it, secure it accordingly, check that a minimum of controls are in place and then accept responsibility for operating the system. NIST also provides documents, checklists, repositories, standards, working groups and validation of automated tools that help with the actual security implementation.
  6. Automated security controls negate human errors. With the premise of all threats being attacks this is nearly a plausible premise. But not all security is technical. Not all threats come from the Internet. DHS, NIST, Mitre, and their partners have pursued automated security controls to enforce and audit security controls for years but automated security controls can only go so far. Human errors, glitches, unexpected conflicts and operational requirements will always factor into the implementation of security.
  7. Audit compatibility as a hallmark of good security. There is a conflict of focus at the heart of the CAG, it seeks to both improve its subset of security and improve audit compatibility. For technical controls this is somewhat achievable using automation, something NIST has pursued for years with government and industry partners. For operational and management controls it results in audit checklists. But audits are fundamentally concerned with testing the particular and repeatable, security needs focus on evaluating the whole to ensure the necessary security results. An audit sees if antivirus software is installed, an evaluation sees if the antivirus software is effective.
  8. Metrics, but only these metrics over here. When selecting the current crop of CAG controls decisions on what to include were reportedly based on metrics of the highest threats. Great idea, a quantitative approach often discovers counter-intuitive facts. Only the metrics were cherry picked. Instead of looking at all realized threats or real threat impacts only a count of common penetration attacks were considered.
  9. With a sample of 1. As a basis for determining what security should focus on the whole breadth of the security profession was queried, so long as they were penetration testers. Yes, penetration testers are some very smart and talented people but penetration testing is to security what HUMINT is to intelligence services. Important players, expert practitioners but limited in scope and best used in conjunction with other intelligence assets.
  10. Assessments rely on paper artifacts. The NIST guidance does not require paper artifacts. The first line in the NIST SP 800-53A preface is, “Security control assessments are not about checklists, simple pass-fail results, or generating paperwork to pass inspections or audits-rather, security controls assessments are the principal vehicle used to verify that the implementers and operators of information systems are meeting their stated security goals and objectives.” NIST SP 800-37 specifically and repeatedly states, “Security accreditation packages can be submitted in either paper or electronic format.”

CAG is a missed opportunity. Of the myriad problems with our current FISMA regime a lot of good could be achieved. The problems with guidance have many causes but can be addressed through cooperative development of best practices outside of NIST. The Assessment Cases for SP 800-53A is an example of how cooperative development can achieve great results and provide clear guidance. Other problems exist and can be addressed with better training and community developments.

My hope is that the Consensus Audit Guidelines will move towards a more open, collaborative development environment. The first release is sure to deliver useful security controls against penetration attacks. As with all good security practices it will likely need to go through a few iterations and lots of critical assessment to mature. An open environment would help foster a more complete consensus.

The Accreditation Decision and the Authorizing Official

Posted February 10th, 2009 by rybolov

The accreditation decision is one of the most key activities in how the US Government secures its systems. It’s also one of the most misunderstood activities. This slideshow aims to explain the role of the Authorizing Official and to give you some understanding into why and how accreditation decisions are made.

I would like to give a big thanks to Joe Faraone and Graydon McKee who helped out.

When the Feds Come Calling

Posted October 21st, 2008 by rybolov

I’ve seen the scenario about a dozen times in the last 2 months–contractors and service providers of all sorts responding to the Government’s security requirements in the middle of a contract.  It’s almost reached the stage where I have it programmed as a “battle drill” ala the infantryman’s Battle Drill 1A, and I’m here to share the secret of negotiating these things.

Let’s see, without naming names, let’s look at where I’ve seen this come up:

  • Non-Government Organizations that assist the Government with para-Government services to the citizens
  • Companies doing research and development funded by the Government–health care and military
  • Universities who do joint research with the Government
  • Anybody who runs something that the Government has designated as “critical infrastructure”
  • State and local governments who use Federal Government data for their social plans (unemployment system, food stamps, and ) and homeland security-esque activities (law enforcement, disaster response)
  • Health Care Providers who service Government insurance plans

For the purposes of this blog post, I’ll refer to all of these groups as contractors or service providers.  Yes, I’m mixing analogies, making huge generalizations, and I’m not precise at all.  However, these groups should all have the same goals and the approach is the same, so bear with me while I lump them all together.

Really, guys, you need to understand both sides of the story because this a cause for negotiations.  I’ll explain why in a minute.

On the Government side:  Well, we have some people we share data with.  It’s not a lot, and it’s sanitized so the value of it is minimal except for the Washington Post Front Page Metric.  Even so, the data is PII that we’ve taken an anonymizer to so that it’s just statistical data that doesn’t directly identify anybody.  We’ve got a pretty good handle on our own IT systems over the past 2 years, so our CISO and IG want us to focus on data that goes outside of our boundaries.  Now I don’t expect/want to “own” the contractor’s IT systems because they provide us a service, not an IT system.  My core problem is that I’m trying to take an existing contract and add security requirements retroactively to it and I’m not sure exactly how to do that.

Our Goals:

  • Accomplishing the goals of the program that we provided data to support
  • Protection of the data outside of our boundaries
  • Proving due-diligence to our 5 layers of oversight that we are doing the best we can to protect the data
  • Translating what we need into something the contractor understands
  • Being able to provide for the security of Government-owned data at little to no additional cost to the program

On the contractor/service provider side:  We took some data from the Government and now they’re coming out of the blue saying that we need to be FISMA-compliant.  Now I don’t want to sound whiney, but this FISMA thing is a huge undertaking and I’ve heard that for a small business such as ourselves, it can cripple us financially.  While I still want to help the Government add security to our project, I need to at least break even on the security support.  Our core problem is to keep security from impacting our project’s profitability.

Our Goals:

  • Accomplishing the goals of the program that we were provided data to support
  • Protection of the data given to us to keep the Government happy and continuing to fund us (the spice must flow!)
  • Giving something to the Government so that they can demonstrate due-diligence to their auditors and IG
  • Translating what we do into something the Government understands
  • Keeping the cost of security to an absolute minimum or at least funded for what we do add because it wasn’t scoped into the SOW

Hmm, looks like these goals are very much in alignment with each other.  About the only thing we need to figure out is scope and cost, which sounds very much like a negotiation.

Little-known facts that might help in our scenario here:

  • Section 2.4 of SP 800-53 discusses the use of compensating controls for contractor and service-provider systems.
  • One of the concepts in security and the Government is that agencies are to provide “adequate security” for their information and information systems.  Have a look at FISMA and OMB Circular A-130.
  • Repeat after me:  “The endstate is to provide a level of protection for the data equivalent or superior to what the Government would provide for that data.”
  • Appendix G in SP 800-53 has a traceability matrix through different standards that can serve as a “Rosetta Stone” for understanding each other.  Note to NIST:  let’s throw in PCI-DSS, Sarbanes-Oxley,  and change ISO 17799 to 27001.

So what’s a security geek to do?  Well, this, dear readers, is Rybolov’s 5-fold path to Government/contractor nirvana:

  1. Contractor and Government have a kickoff session to meet each other and build raport, starting from a common ground such as how you both have similar goals.  The problem really is one of managing each others’ expectations.
  2. Both Government and Contractor perform internal risk assessment to determine what kind of outcome they want to negotiate.
  3. Contractor and Government meet a week later to negotiate on security.
  4. Contractor provides documentation on what security controls they have in place.  This might be as minimal as a contract with the guard force company at their major sites, or it might be just employee background checks and
  5. Contractor and Government negotiate for a 6-month plan-of-action.  For most organizations considering ISO 27001, this is a good time to make a promise to get it done.  For smaller organizations or data , we may not even

Assumptions and dependencies:

  • The data we’re talking about is low-criticality or even moderate-criticality.
  • This isn’t an outsourced IT system that could be considered government-owned, contractor-operated (GO-CO)
