Hi Pete,

        if this becomes an ISO standard will it still be available for free, or
will you need to pay to get copies of it like you do for other ISO
standards? Also, once the ISO standard is defined, how will new open
source contributions be incorporated?

The New ISO Hacking Standard

New York, May 17, 2010 -- The world’s national standards bodies met
again during April, this time in Malaka, Malaysia and they extended
talks about the Open Source Security Testing Methodology Manual. This
ultimate security guide, better known to security experts and hackers
alike as the OSSTMM (spoken like “awesome” but with a “t”), is a formal
methodology for breaking any security and attacking anything the most
thorough way possible. So why is the International Standards
Organization talking about it?

Some national standards organizations like ANSI in the USA and UNINFO in
Italy have had their eye on the OSSTMM for years. Others, like DIN in
Germany, were only recently shown the benefits of the OSSTMM but then
supported it immediately. Released for free in January 2001 by Pete
Herzog as the underdog to the security industry’s product-focused
security advice, the manual achieved an instant cult following. The fact
that OSSTMM is open to anyone for peer review and further research led
to it growing from its initial 12 page release to its current size of
200. The international support community also grew to over 7000 members
with dozens of research contributors dedicating their time to enhancing
it. For testing security operations and devising tactics it has no
equal. Its popularity and growth happened so fast that the non-profit
organization ISECOM created the Open Methodology License (OML) asserting
the OSSTMM as an open Trade Secret to assure it remained free, as in no
price, as well as free from commercial and political influence. The
OSSTMM seemed to have all the features of being the answer for securing
the world except that it had never been formally recognized…until now.

With such fanatical devotion from experts and the underground, the
OSSTMM soon gained the attention of governments from city to state to
national which is how it eventually got to the ISO. ISO is the acronym
of the International Standards Organization. Headquartered in Geneva,
Switzerland, ISO is the collection of people who create manuals
standardizing all sorts of things like paper sizes (ISO 216), what
determines a water-resistant watch (ISO 2281), how to properly conduct
quality management (ISO 9001), the C programming language (ISO 9899),
shoe sizes (ISO 9407), or what defines proper information security (ISO
27001 and 27002). However they currently have nothing on operational
security, the means of assuring security for processes and systems in
action. The only way that can be done is by attacking it every way
possible, pushing the impossible, and see why and how the security
breaks. That’s exactly what the OSSTMM does.

During past ISO meetings, the Subcommittee 27, mostly known for its
ISO/IEC 27000 family (Information Security Management System) and
ISO/IEC 15408 (Common Criteria), already discussed the topic within
different working groups (WG) with no clear outcome. Meanwhile, some
ISECOM members, like Dr. Fabio Guasconi in Italy and Heiko Rudolph
together with Aaron Brown in Germany, have become active participants in
their respective ISO national bodies to help inform their ISO colleagues
about the many benefits the OSSTMM could provide to various ISO
standards. In Malaka, Dr. Guasconi, the national body representative of
Italy’s UNINFO, made significant progress on this front when he held a
complete presentation to WG4 and WG3, the latter one being devoted to
security evaluation criteria. WG3 then eventually expressed a formal
interest in carving deeper into the security testing methodology topic,
issuing and approving a resolution for starting a study period of one
year. The base of this study period, which is the first step towards a
standardization path, would be constituted by the OSSTMM 3 and all
security experts from national bodies will freely contribute and comment
on it. By the end of the study period it will be determined how ISO will
receive OSSTMM contents in its family of security standards. As outlined
in Malaka’s presentation there are many standards that could benefit
from a standard aligned with OSSTMM contents, such as 21827, 15408,
18045, 19790 and, of course, 27001. Parts of OSSTMM concepts have
already been posted as comments within the project for ISO 27008, which
is dedicated to technical audits on security controls. It looks like
this hacker’s guide has really grown up.

The OSSTMM is currently in its third revision and still in Beta,
therefore only available to team members, select reviewers, and federal
government agencies that require it for drafting policy. This third
version is a complete re-write of the methodology and has at its
foundation the ever-elusive security and trust metrics. It required 6
years of research and development to produce the perfect operational
security metric, an algorithm which computes the Attack Surface of
anything. In essence, it is a numerical scale to show how unprotected
and exposed something currently is. This number is the basis required
for making a proper trust assessment, another feature of the OSSTMM 3 to
do away with risk assessment in favor of a more factual metric using
trust. Security professionals, military tacticians, and security
researchers know that without knowing how exposed a target is, it’s just
not possible to say how likely a threat will cause damage and how much.
But to know this requires a thorough security test which happens to be
exactly what the OSSTMM provides.

To say the OSSTMM 3 is a very thorough methodology is an understatement.
It currently has 12 chapters covering proper attack procedures, rules of
engagement, proper analysis, critical security thinking, and trust
metrics. It provides 17 modules like Visibility Audit, Trust
Verification, Property Validation, and Competitive Intelligence
Scouting, each which describes multiple attacks (called Tasks), for 5
different interaction types with a target (called Channels) organized by
technical knowledge and equipment requirements as Human, Physical,
Telecommunications, Data Networks, and Wireless. An example attack task
under the Wireless Channel for Trust Verification states, “Test and
document the depth of requirements for access to wireless devices within
the scope with the use of fraudulent credentials.” As if that wasn’t
already deep, it even waxes security philosophy with things like,
“Compliance requirements which enforce protection measures as a
surrogate for responsibility are also a substitute for accountability,”
and “Fear doesn’t motivate a person to find complacency any more than
security motivates a person to find productivity.”

The OSSTMM may some day be officially recognized by national standards
bodies. However until then, like an indie band with over 4 million
downloads, the OSSTMM is not suffering from brand recognition. Still, to
be an ISO standard is alluring to OSSTMM developers and fans alike. They
know that to be there, they have proved that the OSSTMM 3 is needed,
thorough, and important enough for leaders and policy makers to consider
adopting.

If OSSTMM does become recognized by an international standards body, it
would also help remove some of the vendor influence from current
security laws where product focus often diminishes security and costs
organizations more money. It would allow for the legal framework to
focus on what is an acceptable attack surface rather than on which are
accepted products. -Based on OSSTMM, government organizations could also
determine which environmental controls are required for the
infrastructure to prevent employees with a lack of security knowledge or
focus from making bad security decisions as opposed to which brand of
security awareness training will be need to be bought. It could also
mean vendors would need to reach higher to surpass the bar set by the
law instead of forcing the law to stoop down to what the vendor can
provide.

People who want to support getting the OSSTMM 3 into the ISO family can
contact ISECOM to help build up the best possible proposal and to
support it through the November 2010 meeting in Berlin.

About ISECOM:
ISECOM is a non-profit, security research organization located in
Barcelona, Spain and New York. With the mission to “make sense of
security” the organization produces the international standard for
security testing as well as many other projects including trust
analysis, home security, and teen cybersecurity awareness. All projects
at ISECOM are completed the “open source” way through collaboration and
published for free at the ISECOM website (www.isecom.org).
