‣ DEVOPS IS CHANGING AND THERE IS A BIG RISK
TO LOSE OUR WAY.
‣ SECURITY IS IN CRISIS
‣ SECURITY AT FORWARD-LEANING SHOPS HAVE
FOUND THE NEW WAY.

WAY OF SECURITY IN DEVOPS.
SUMMARY

@WICKETT
‣ WHY DO WE HAVE DEVOPS?
‣ DID WE BUILD DEVOPS PROPERLY?

@WICKETT
Security is in Crisis

@WICKETT
Companies are spending a great deal on
security, but we read of massive computer-
related attacks. Clearly something is wrong.
The root of the problem is twofold:
we’re protecting the wrong things,
and we’re hurting productivity in the process.
THINKING SECURITY, STEVEN M. BELLOVIN 2015

[Security by risk assessment] introduces
a dangerous fallacy: that structured
inadequacy is almost as good as
adequacy and that underfunded security
eﬀorts plus risk management are about
as good as properly funded security work

@WICKETT
Security is often the
cultural outlier in an
organization

@WICKETT
many security teams work
with a worldview where their
goal is to inhibit change as
much as possible

“SECURITY PREFERS A SYSTEM POWERED
OFF AND UNPLUGGED”
- DEVELOPER

“…THOSE STUPID DEVELOPERS”
- SECURITY PERSON

@WICKETT
It is 30 times cheaper
to ﬁx security defects
in dev vs. Prod
NIST, 2002, The Economic Impacts of Inadequate Infra for Software Testing

@WICKETT
Security must
Change or Die

@WICKETT
“EVERY ASPECT OF MANAGING WAFS IS AN ONGOING
PROCESS. THIS IS THE ANTITHESIS OF SET IT AND FORGET IT
TECHNOLOGY. THAT IS THE REAL POINT OF THIS RESEARCH.
TO MAXIMIZE VALUE FROM YOUR WAF YOU NEED TO GO IN
WITH EVERYONE’S EYES OPEN TO THE EFFORT REQUIRED TO
GET AND KEEP THE WAF RUNNING PRODUCTIVELY.”
- WHITEPAPER FROM AN UNDISCLOSED WAF VENDOR

THE AVERAGE TIME TO DELIVER CORPORATE IT PROJECTS
HAS INCREASED FROM ~8.5 MONTHS TO OVER 10
MONTHS IN THE LAST 5 YEARS
Revving up your Corporate RPMs, Fortune Magazine, Feb 1, 2016
THE GROWTH OF [SECURITY] FUNCTIONS WHICH IS TOO
OFTEN POORLY COORDINATED… [RESULTING IN] A
PROLIFERATION OF NEW TASKS IN THE AREAS OF
COMPLIANCE, PRIVACY AND DATA PROTECTION.

@WICKETT
Many security professionals
have a hard time adapting their
existing practices to a world
where requirements can change
every few weeks, or where they
are never written down at all.

@WICKETT
Security didn’t get an
invite to the DevOps
party!

“You Build It, You Secure It” DOES 2017

@WICKETT
Read-only containers and
serverless shift the
security story to almost
100% application

@WICKETT
DevOps
A New Traveling Companion
for Security
(…and probably the only way to survive)

@WICKETT
High performers spend 50 percent less
time remediating security issues than
low performers.
By better integrating information
security objectives into daily work,
teams achieve higher levels of IT
performance and build more secure
systems.

High performing orgs achieve
quality by incorporating
security (and security teams)
into the delivery process

@WICKETT
A security team who embraces
openness about what it does and
why, spreads understanding.

@WICKETT
Runtime is arguably the
most important place to
create feedback loops

‣ POLICIES AND PROCEDURES IN PLACE
‣ EFFECTIVE EXECUTION OF THOSE POLICIES TO
ALLOW YOU TO KEEP FUNCTIONING
‣ MOST OF PCI AND OTHER FRAMEWORKS
PROVIDE REASONABLY GOOD PRACTICES *IF*
YOU REMOVE ALL THE WATERFALL BITS
UNDERSTAND AUDITORS

@WICKETT
[Deploys] can be treated as
standard or routine changes
that have been pre-approved
by management, and that
don’t require a heavyweight
change review meeting.

SEPARATION OF DUTIES CONSIDERED HARMFUL

@WICKETT
In environments where one individual
performs multiple roles (for example,
administration and security operations), duties
may be assigned such that no single
individual has end-to-end control of a process
without an independent checkpoint.
(aka Auditable Delivery Pipeline)

@WICKETT
Developers with Access
to Production, Oh My!!!

@WICKETT
‣ DON’T SLOW DELIVERY
‣ CONTINUOUS TESTING AND VALIDATION
‣ TESTING ON THE SIDE OF THE PIPELINE
‣ PENETRATION TESTING OUTSIDE OF DELIVERY
FAST AND NON-BLOCKING

@WICKETT
Currently, at Signal
Sciences we do about 15
deploys per day

@WICKETT
Roughly 10,000 deploys
in the last 2.5 yrs

@WICKETT
CD is how little you
can deploy at a time

@WICKETT
We optimized for cycle
time—the time from code
commit to production

GAVE POWER TO THE TEAM TO DEPLOY

@WICKETT
Signal Sciences is a
software as a service
company and a security
company

@WICKETT
Security is part of CI/
CD and the overall
delivery pipeline

SECURITY CONSIDERATIONS
What have I bundled into my
app that leaves me
vulnerable?
Do my build acceptance
tests and integration tests
catch security issues before
release?
Am I being attacked right
now? Is it working?

Embrace Secrecy Create Feedback Loops

Enforce Stability Create Chaos

Slow Validation Fast and Non-blocking
Certainty Testing Adversity Testing

Process Driven The Paved Road

@WICKETT
The goal should be to come up with a
set of automated tests that probe and
check security configurations and
runtime system behavior for security
features that will execute every time
the system is built and every time it is
deployed.

@WICKETT
Security tools are
intractably noisy and
difficult to use

@WICKETT
A method of
collaboration was
needed for devs, ops
and security eng.

@WICKETT
There needed to be a
new language to span
the parties

@WICKETT
Started Gauntlt
4 years ago

@WICKETT
Open source, MIT License
Gauntlt comes with pre-canned steps that
hook security testing tools
Gauntlt does not install tools
Gauntlt wants to be part of the CI/CD pipeline
Be a good citizen of exit status and stdout/
stderr

# download example attacks from github
# customize the example attacks
# now you can run gauntlt
$ gauntlt

Feature: Look for cross site scripting (xss) using arachni
against a URL
Scenario: Using arachni, look for cross site scripting and verify
no issues are found
Given "arachni" is installed
And the following profile:
| name | value |
| url | http://localhost:8008 |
When I launch an "arachni" attack with:
"""
arachni —check=xss* <url>
"""
Then the output should contain "0 issues were detected."

Then
What?
