1. As developers have become the driving force behind cloud adoption, there is a need to realign security practices with DevOps workflows and priorities. 2. A blueprint approach to cloud security involves enumerating cloud assets, threat modeling for common workloads, and integrating controls across the full technology stack. 3. With a blueprint model and automated security tools integrated into the development pipeline, security can provide coverage throughout the software development lifecycle without slowing innovation or agility.

SECURITY & DEVOPS

1. DevOps implications on Security
2. Developing a Blueprint approach to cloud security

3. What Drives Cloud Adoption?
• Developers are the driving force behind cloud adoption
• Main reason developers are using cloud services?
Innovation
ability to move
fast
deploy
infrastructure
without IT
overhead
ship code without
delays

4. Software Drives Business Innovation

5. Developer Perspective

8. Aligning DevOps with Security
Critical questions to answer:
1. What are we protecting?
2. What controls must be in place?
3. How do you integrate security into your daily workflow?

9. Reshaping the Security/Dev/Ops Relationship

10. Rules of the Road
No Yes
1 Random opinions
Everyone works from same
security blueprint
2 General set of controls
Controls specific
to your cloud blueprint
3 Security gateways and overlays
Security is part of
immutable infrastructure
4 Periodic audits
Security testing part of
regression framework
5
Vulnerabilities are escalated
and negotiated for resolution
Vulnerabilities are bugs
Critical vulnerabilities are critical bugs

11. Perception vs Reality
Our ability to accurately estimate
attack surface is compromised by
our weak sense of perception
More reliable approach:
1. Identify your cloud assets
2. Measure your exposure
3. Implement controls

12. Blueprint Model for
DevOps Security

13. Enumerate Your Cloud Footprint
Generalize common workloads into infrastructure-’blueprints’
Blueprint Driven Approach

2. Basic Cloud Security
• Agile development team,
coupled to immature security
program
• Minimal use of cloud provider
and OSS security tools
Traditional Security
1. Non-Cloud Native
• Lift & Ship infrastructure
migration
• Traditional on-premises
security tools and processes
• Limited agility
