WHAT ARE THE GOALS AND
PRINCIPLES IN DEVSECOPS?
Make security a first-
class problem in
DevOps
Make security a first-class
participant in DevOps
Increase trust
between dev, ops,
and sec
Integrate security
practices and ideas into
DevOps culture
Wire security into
DevOps workflows to
incrementally improve

Pre-Commit:
The Paved Road

Dev, Sec, and Ops teams build secure by default
frameworks, libraries, and services
Popularized by Netflix "Gates
to Guardrails"
Operations: Automated
pipelines build, certify, and
publish cloud infrastructure /
machine images
Development: Secure templates
for Web, APIs, front-end,
serverless projects
Security: Automated security
pipeline scans, unit tests,
acceptance tests, production
assertions

CI / CD Security Controls
Commit:

Integrate tools to
automate build, test,
acceptance, and
deployment of
infrastructure, cloud,
and applications into a
repeatable workflow
Continuous Integration & Delivery Security Controls

security team prior to triggering the build pipeline:

CI / CD Security Controls: Acceptance Tes7ng

Build pipelines contain
artifacts from security
scans and compliance
checks
CI / CD Security Controls: Audit Reports

Acceptance:

Serious vulnerabilities can be inherited from open source libraries,
docker images, infrastructure templates, and serverless functions:
WARNING:
Some tools may
not check
transitive
dependencies
Carefully review
content before
usage
Run tools to
automatically
the scan code
base / images
Identify external
dependencies
Check against
public
vulnerability
database(s)
Integrate supply
chain security
scanning into
CI/CD

Opera&ons:
Continuous Security Compliance

Leveraging security configuration tools to
automate audit and compliance checks:
Test the server and
infrastructure
configuration against
expected baseline and
report any deviations
Tests should include
severity, risk level, and
description information
Match tests against
compliance checklist
items or regulatory
policies
Automated testing tools
available for Linux,
Unix, Windows, AWS,
Azure and VMWare
