CLASP
• Comprehensive, Lightweight Application Security
Process
• Centered around 7 AppSec Best Practices
• Cover the entire software lifecycle (not just
development)
• Adaptable to any development process
• Defines roles across the SDLC
• 24 role-based process components
• Start small and dial-in to your needs
Microsoft SDL
• Built internally for MS software
• Extended and made public for others
• MS-only versions since public release
Touchpoints
• Gary McGraw’s and Cigital’s model
BSIMM
• Gary McGraw’s and Cigital’s model
• Quantifies activities of software security
initiatives of 51 firms
Derived from SAMM beta

BSIMM – Open SAMM Mapping
Lessons Learned
• Microsoft SDL
• Heavyweight, good for large ISVs
• Touchpoints
• High-level, not enough details to execute against
• BSIMM
• Stats, but what to do with them?
• CLASP
• Large collection of activities, but no priority
ordering
• ALL: Good for experts to use as a guide, but hard
for non-security folks to use off the shelf

We need a Maturity Model
An organization’s
behavior
changes slowly
over time
Changes must
be iterative while
working toward
long-term goals
There is no
single recipe that
works for all
organizations
A solution must
enable riskbased choices
tailored to the
organization
Guidance related
to security
activities must be
prescriptive
A solution must
provide enough
details for nonsecurity-people
Overall, must be
simple, welldefined, and
measurable

SAMM Security Practices
• From each of the Business Functions, 3 Security Practices are
defined
• The Security Practices cover all areas relevant to software security
assurance
• Each one is a ‘silo’ for improvement
P
D B
T
SAMM
Under each Security
Practice
•
Three successive Objectives under each Practice define how it
can be improved over time
•
•
This establishes a notion of a Level at which an organization
fulfills a given Practice
The three Levels for a Practice generally correspond to:
•
(0: Implicit starting point with the Practice unfulfilled)
•
1: Initial understanding and ad hoc provision of the Practice
•
2: Increase efficiency and/or effectiveness of the Practice
•
3: Comprehensive mastery of the Practice at scale

Creating Scorecards
• Gap analysis
• Capturing scores from detailed
assessments versus expected
performance levels
• Demonstrating improvement
• Capturing scores from before and
after an iteration of assurance
program build-out
• Ongoing measurement
• Capturing scores over consistent time
frames for an assurance program that
is already in place

•
To make the “building blocks” usable, SAMM
defines Roadmaps templates for typical kinds
of organizations
•
Independent Software Vendors
•
Online Service Providers
•
Financial Services Organizations
•
Government Organizations
Tune these to your own targets / speed

Critical Success Factors
• Get initiative buy-in from all stakeholders
• Adopt a risk-based approach
• Awareness / education is the foundation
• Integrate security in your development /
acquisition and deployment processes
• Provide management visibility

Project Roadmap
Build the SAMM community:
• List of SAMM adopters
• Workshops at AppSecEU and AppSecUSA
V1.1:
• Incorporate tools / guidance / OWASP projects
• Revamp SAMM wiki
V2.0:
• Revise scoring model
• Model revision necessary ? (12 practices, 3 levels, ...)
• Application to agile
• Roadmap planning: how to measure effort ?
• Presentations & teaching material
• …
