Risk Management
Time to blow it up and start over?

Met E.T. Jaynes
probability theory, the logic of
science
Kuhn’s Protoscience
 A stage in the development of a science
that is described by:

• somewhat random fact gathering
  (mainly of readily accessible data)
• a “morass” of interesting, trivial,

  irrelevant observations
• A variety of theories (that are spawned

  from what he calls philosophical
  speculation) that provide little guidance
  to data gathering

let’s talk governance
governance, without metrics &
models, is superstition
governance, with metrics &
models, describes capability to
manage risk
Why does what you
execute on and how
you execute matter?
governance, without metrics & models,
is superstition
governance, with metrics & models,
describes capability to manage risk

measurably good governance
practices (can/will) reduce risk
measurably good governance is
simply a description of capability to
manage risk
not sucking eggs at security is a
good idea
compliance*, without metrics, is
superstition
compliance*, with metrics, is risk
management

What is risk?
a. Risk is notional
b. Risk is tangible
Problems with “tangible”

- complex systems, complexity
science

- usefulness outside of the very
specific

- measurements

- lots of belief statements
How Complex Systems Fail
(Being a Short Treatise on the Nature of Failure; How Failure
is Evaluated; How Failure is Attributed to Proximate Cause;
and the Resulting New Understanding of Patient Safety)

%20Complex%20Systems
%20Fail.pdf
Catastrophe requires multiple failures
single point failures are not enough..

The array of defenses works. System operations are generally successful. Overt
catastrophic failure occurs when small, apparently innocuous failures join to create
opportunity for a systemic accident. Each of these small failures is necessary to cause
catastrophe but only the combination is sufficient to permit failure. Put another way, there are
many more failure opportunities than overt system accidents. Most initial failure trajectories
are blocked by designed system safety components. Trajectories that reach the operational
level are mostly blocked, usually by practitioners.


Complex systems contain changing mixtures of failures latent within them.

The complexity of these systems makes it impossible for them to run without multiple
flaws being present. Because these are individually insufficient to cause failure they are
regarded as minor factors during operations. Eradication of all latent failures is limited
primarily by economic cost but also because it is difficult before the fact to see how
such failures might contribute to an accident. The failures change constantly
because of changing technology, work organization, and efforts to eradicate failures.
Complex systems run in degraded mode.

Post-accident attribution accident to a ‘root
cause’ is fundamentally wrong.

All practitioner actions are gambles.

Human expertise in complex systems is
constantly changing

Change introduces new forms of failure.

Views of ‘cause’ limit the effectiveness of
defenses against future events.
Problems with “notional”

- becomes difficult to extract wisdom - we
want a “Gross Domestic Product”

- unable to be defended

- pseudo-scientific

- lots of belief statements
from Mark Curphey’s SecurityBullshit
What is risk?
uses of “risk”

- engineering
         - complex systems says “no”
- financial
          - no 110% return on your firewall
- medical
          - requires data
our standards say:

Find issue, call
issue bad, fix issue,
hope you don’t find
it again...
Managing risk means aligning the
capabilities of the organization, and
the exposure of the organization
with the tolerance of the data

    Catastrophe requires multiplefailures single point failures are not enough.. The array of defenses works. System operations are generally successful. Overt catastrophic failure occurs when small, apparently innocuous failures join to create opportunity for a systemic accident. Each of these small failures is necessary to cause catastrophe but only the combination is sufficient to permit failure. Put another way, there are many more failure opportunities than overt system accidents. Most initial failure trajectories are blocked by designed system safety components. Trajectories that reach the operational level are mostly blocked, usually by practitioners. Complex systems contain changing mixtures of failures latent within them. The complexity of these systems makes it impossible for them to run without multiple flaws being present. Because these are individually insufficient to cause failure they are regarded as minor factors during operations. Eradication of all latent failures is limited primarily by economic cost but also because it is difficult before the fact to see how such failures might contribute to an accident. The failures change constantly because of changing technology, work organization, and efforts to eradicate failures.

    Complex systems runin degraded mode. Post-accident attribution accident to a ‘root cause’ is fundamentally wrong. All practitioner actions are gambles. Human expertise in complex systems is constantly changing Change introduces new forms of failure. Views of ‘cause’ limit the effectiveness of defenses against future events.
