A couple of weeks ago I went to the NIST Cloud Conference for the afternoon security sessions.  You can go grab the slides off the conference site.  Good stuff all around.

Come to think of it, I haven’t blogged about FedRAMP, maybe it’s time to.

FedRAMP is a way to do security authorization (formerly certification and accreditation, get with the times, man) on a cloud then let tenant projects use that authorization.  Hmmm, sounds like…. a General Support System with common controls and Major Applications that inherit those controls.  This isn’t really anything new, just the “bread and butter” security management concepts scoped to a cloud.  Basically what will happen with FedRAMP is that they have 3 standards: DoD, DHS, and GSA (most stringent first) and cloud providers get authorized against that standard.  Then when a project wants to build on that cloud, they can use that authorization for their own authorization package.

All things considered, FedRAMP is an awesome idea.  Now if we can get the holdout agencies to actually acknowledge their internal common controls, I’ll be happy–the background story being that some number of months ago I was told by my certifier that “we don’t recognize common controls so even though you’re just a simple web application you have to justify every control even if it’s provided to you as infrastructure.”  No, still not bitter at all here, but I digress….

And then there are the pieces that I haven’t seen worked out yet:

• Mechanism of Sharing: As a service provider, it’s hard enough to keep one agency happy.  Add in 5 of them and it gets nearly impossible.  This hasn’t really been figured out, but in Rybolov’s small, myopic world, a panel of agencies owning an authorization for a cloud provider means that the cloud never gets authorized.  The way this has been “happening in the wild” is that one agency owns the authorization and all the other agencies get the authorization package from that agency.
• Using FedRAMP is Optional: An agency or project can require their own risk assessment and authorization even though a FedRAMP one is available.  This means that if the agency’s auditors don’t understand the process or the “risk monkeys” (phrase courtesy of My Favorite Govie) decree it, you lose any kind of cost savings and time savings that you would get by participating in FEDRAMP.
• Cloud Providers Rule the Roost: Let’s face it, as much as the Government wants to pretend that the cloud providers are satisfying the Government’s security requirements, we all know that due to the nature of catalogs of controls and solution engineering, the vendor here has the advantage.  Nothing new, it’s been happening that way with outsourcing, only now it’s immediately evident.  Instead of trying to play ostrich and stick our heads in the sand, why don’t we look at the incentives for the cloud providers and see what makes sense for their role in all this.
• Inspector General Involvement: I don’t see this happening, and to be honest, this scares the hell out of me.  Let me just invoke Rybolov’s Law: “My solution is only as good as my auditor’s ability to understand it.”  IE, if the IGs and other auditors don’t understand FedRAMP, you don’t really have a viable solution.

As I’m going through a wide variety of control frameworks in a managed services/cloud environment, I’m reminded of how controls work when you’re a service provider.  Mentally, I break them down into four “buckets”:

• Controls that I provide to all customers as part of my baseline. In other words, these are things that I do for all of my customers because it’s either part of the way that I do business or it makes sense to do it once and scale it out to everybody.  Typically these are holistic information security program things (ISO 17799/27001/27002 or similar) matched up with my service-delivery architecture.
• Controls that I provide as an add-on service. Not all of my customers need these but I want to offer them to my customers to help them with their security program.  Usually these are services and products supporting a regulatory framework specific to one industry:  PCI-DSS, FISMA, GLBA, etc fit in here if my market is not exclusive to customers governed by those regulations.  In order to keep the base cost for the other customers low, these aren’t included in the base service but are available for a price.
• Controls that I am planning on building. I don’t have them yet but they’re on my roadmap.  Sometimes this is how I get into new markets by building the products and services that match up against the regulatory framework for that market, then build to that as a specification.
• Controls that I will not provide. Maybe this control doesn’t apply to my products and service (The “We don’t actually own a Windows/HP-UX/AIX server” problem).  Maybe the controls framework didn’t scope my solutions into its assumptions.  Maybe the economics of this didn’t work out.  Maybe I don’t provide this because it’s dishonest for both myself and you as my customer for me to say I provide this–think along the lines of accepting risk on your behalf which puts me into a conflict of interest.  This is why any vendor who says they provide 100% compliancy against FooFramework is lying.

Transparency ties it all together.  The good providers will tell you upfront which controls belong in which buckets.

Somedays I feel like people are reading this blog and getting ideas that they turn around and steal.  Then I take my pills and my semi-narcisistic feelings go away.  =)

So anyway, B|A|H threw me for a loop this afternoon.  They released a report on the cybersecurity workforce.  You can check out the article on The Register or you can go get the report from here.  Surprise, we don’t have anywhere near enough security people to go around.  I’ve been saying this for years, I think B|A|H is stealing my ideas by using Van Eck phreaking on my brain while I sleep.

 Some revelations from the executive summary:

• The pipeline of potential new talent is inadequate.  In other words, demand is growing and the amount of people that we’re training is not growing to meet the demand.
• Fragmented governance and uncoordinated leadership hinders the ability to meet federal cybersecurity workforce needs.  Nobody’s so far been able to articulate how we build an adequate supply of security folks to keep up with demand and most of our efforts have been at the execution level.
• Complicated processes and rules hamper recruiting and retention efforts.  It takes maybe 6 months to hire a government employee, this is entirely unsatisfactory.  My current project I was cleared for for 3 years, took a 9-month break, and it took me 6 months to get cleared again.
• There is a disconnect between front-line hiring managers and government’s HR specialists.  Since the HR folks don’t know what the real job description is, hiring information security people is akin to buzzword bingo.

These are all the same problems the private sector deals with, only in true Government stylie, we have it on a larger scale.

Now for the things that no self-respecting contractor will admit (hmm, what does this say about me?  I’m not sure yet)….

If you do not have an adequate supply of workers in the industry, outsourcing cybersecurity tasks to contractors will not work.  It works something like this:

• High Demand = High Bill Rate.
• High Bill Rate = More Contractor Interest
• More Contractor Interest + High Bill Rate +  Low Supply = High Rate of Charlatans

Contractors do not have the labor pool to tap into to satisfy their contracts.  If you want to put on your cynic hat (all the Guerilla-CISO staff have theirs permanently attached with wood screws), you could say that the B|A|H report was trying to get the Government to pump more money into workforce development so that they could then hire those people and bill them back to the Government.  It’s a twisted world, folks.

Current contractor labor pools have some of the skills necessary for cybersecurity but not all.  More info in future blog posts, but I think a simple way to summarize it is to say that our current workforce is “tooled” around IT security compliance and that we are lacking in large-scale attack and defense skills.

Not only do we need more people in the security industry, but we need more security people in Government.  There is a set of tasks called “inherent government functions” that cannot be delegated to contractors.  Even if you solely increase the contractor headcount, you still have to increase the government employee headcount in order to manage the contractors.

Face it, your security requirements suck. I’ll tell you why.  You write down controls verbatim from your catalog of controls (800-53, SoX, PCI, 27001, etc), put it into a contract, and wonder how come when it comes time for security testing, we just aren’t talking the same language.  Even worse, you put in the cr*ptastic “Contractor shall be compliant with FISMA and all applicable NIST standards”.  Yes, this happens more often than I could ever care to count, and I’ve seen it from both sides.

The problem with quoting back the “requirements” from a catalog of controls is that they’re not really requirements, they’re control objectives–abstract representations of what you need in order to protect your data, IT system, or business.  It’s a bit like brain surgery using a hammer and chisel–yes, it might work out for you, but I don’t really feel comfortable doing it or being on the receiving end.

And this is my beef with the way we manage security controls nowadays.  They’re not requirements, functionally they’re a high-level needs statement or even a security concept of operations.  Security controls need to be tailored into real requirements that are buildable, testable, measurable, and achievable.

Did you say “Wrecks and Female Pigs’? In the contracting world, we have 2 vehicles that we use primarily for security controls: Statements of Work (SOW) and Engineering Requirements.

• Statements of Work follow along the lines of activities performed by people.  For instance, “contractor shall perform monthly 100% vulnerability scanning of the $FooProject.”
• Engineering Requirements are exactly what you want to have build.  For instance, “Prior to displaying the login screen, the application shall display the approved Generic Government Agency warning banner as shown below…”

Let’s have a quick exercise, shall we?

What 800-53 says: The information system produces audit records that contain sufficient information to, at a minimum, establish what type of event occurred, when (date and time) the event occurred, where the event occurred, the source of the event, the outcome (success or failure) of the event, and the identity of any user/subject associated with the event.

How It gets translated into a contract: Since it’s more along the lines of a security functional requirement (ie, it’s a specific functionality not a task we want people to do), we brake it out into multiple requirements:

The $BarApplication shall produce audit records with the following content:

• Event description such as the following:
  • Access the $Baz subsystem
  • Mounting external hard drive
  • Connecting to database
  • User entered administrator mode
• Date/time stamp in ‘YYYY-MM-DD HH:MM:SS’ format;
• Hostname where the event occured;
• Process name or program that generated the event;
• Outcome of the event as one of the following: success, warn, or fail; and
• Username and UserID that generated the event.

For a COTS product (ie, Windows 2003 server, Cisco IOS), when it comes to logging, I get what I get, and this means I don’t have a requirement for logging unless I’m designing the engineering requirements for Windows.

What 800-53 says: The The organization configures the information system to provide only essential capabilities and specifically prohibits and/or restricts the use of the following functions, ports, protocols, and/or services: [Assignment: organization-defined list of prohibited and/or restricted functions, ports, protocols, and/or services].

How It gets translated into a contract: Since it’s more along the lines of a security functional requirement, we brake it out into multiple requirements:

The $Barsystem shall have the software firewall turned on and only the following traffic shall be allowed:

• TCP port 443 to the command server
• UDP port 123 to the time server at this address
• etc…..

If we drop the system into a pre-existing infrastructure, we don’t need firewall rules per-se as part of the requirements, what we do need is a SOW along the following lines:

The system shall use our approved process for firewall change control, see a copy here…

So what’s missing, and how do we fix the sorry state of requirements?

This is the interesting part, and right now I’m not sure if we can, given the state of the industry and the infosec labor shortage:  we need security engineers who understand engineering requirements and project management in addition to vulnerability management.

Don’t abandon hope yet, let’s look at some things that can help….

Security requirements are a “best effort” proposition.  By this, I mean that we have our requirements and they don’t fit in all cases, so what we do is we throw them out there and if you can’t meet the requirement, we waiver it (live with it, hope for the best) or apply a compensating control (shield it from bad things happening).  This is unnerving because what we end up doing is arguing all the time over whether the requirements that were written need to be done or not.  This drives the engineers nuts.

It’s a significant amount of work to translate control objectives into requirements.  The easiest, fastest way to fix the “controls view” of a project is to scope out things that are provided by infrastructure or by policies and procedures at the enterprise level.  Hmmm, sounds like explicitly stating what our shared/common controls are.

You can manage controls by exclusion or inclusion:

• Inclusion:  We have a “default null” for controls and we will explicitly say in the requirements what controls you do need.  This works for small projects like standing up a pair of webservers in an existing infrastructure.
• Exclusion:  We give you the entire catalog of controls and then tell you which ones don’t apply to you.  This works best with large projects such as the outsourcing of an entire IT department.

We need a reference implementation per technology.  Let’s face it, how many times have I taken the 800-53 controls and broken them down into controls relevant for a desktop OS?  At least 5 in the last 3 years.  The way you really need to do this is that you have a hardening guide and that is the authoritative set of requirements for that technology.  It makes life simple.  Not that I’m saying deviate from doctrine and don’t do 800-53 controls and 800-53A test procedures, but that’s the point of having a hardening guide–it’s really just a set of tailored controls specific to a certain technology type.  The work has been done for you, quit trying to re-engineer the wheel.

Use a Joint Responsibilities Matrix.  Basically this breaks down the catalog of controls into the following columns:

• Control Designator
• Control Title
• Provided by the Government/Infrastructure/Common Control
• Provided by the Contractor/Project Team/Engineer

• When Standards Aren’t Good Enough
• 20 Critical Security Controls: What They Did Right and What They Did Wrong
• Opportunity Costs and the 20 Critical Security Controls
• 20 Critical Security Controls: Control-by-Control
• NIST Cloud Conference Recap

So I was doing my usual “Beltway Bandit Perusal of Opportunities for Filthy Lucre” also known as diving into FedBizOps and I found this gem.  Basically what this means is that sometime this summer, NIST is going to put out an RFP for contractors to further develop SCAP using ARRA funds.

Keeping in mind that this isn’t the official list of what NIST wants done under this contract, but it’s interesting to look at from an angle of where SCAP will go over the next couple of years:

1. Evolution of the SCAP protocol and specifications thereof
2. Feasibility studies, development, documenting, prototyping, and road-mapping of SCAP expansions (e.g., remediation capability) and analog protocols (e.g., Network Event Content Automation Protocol
3. Implementation and maintenance support for the Security Automation Content Validation Program
4. Maintenance support for the SCAP Product Validation Program
5. Pilot, beta, and production support for SCAP and security automation use-cases
6. Content development, modification, and testing
7. Infrastructure and reference implementation development in JAVA, C++, and C programming languages
8. Data trust models and data provenance solutions.

So how do you play?  Well, the first thing is that you respond to the notice with a capabilities statement saying “yes, we have experience in doing what you want”–there is a list of specifics in the original notice.  Then sign up for FedBizOps and follow the announcement so you can get changes and the RFP when it comes out.
