The Big Picture

• Think about what we see today in terms of the Cloud stack

– IaaS->PaaSSaaS

• Think about an Agile SDLC– From Rqmts Design Build

TestDeploy – It’s fully automated

• Think about how people are impacted– Business Users Developers IT Ops

What is DevOps?

Characteristics– Treating “Infrastructure as Code” is fundamental to

DevOps • Automating the work of setting up and maintaining

systems infrastructure• Making it defined, efficient, testable, auditable and

standardized

– Automated Testing is part of your pipeline– Automated CI / CD pipeline– Automated application deployment– Logging & Traceability of all changes

Definitions– Applying agile techniques to operations– Getting development and operations to work

together– DevOps is the last mile of Agile– How to deploy software with speed and confidence– DevOps is about accelerating software deployment

Security & DevOps

• DevOps and CD allow businesses to deploy software far more frequently than in the past, increasing consistency, predictability, and ultimately, quality.

• The deltas between builds are much smaller, reducing the likelihood of catastrophic errors. Bugs are smaller and easier to fix

• While functional problems can often be detected through regular use, security vulnerabilities are harder to spot.

• Since “infrastructure as code” allows VM’s to be provisioned and de-provisioned in minutes, keeping track of security vulnerabilities without automation is impossible.

• Big Question: How can we ensure the environments are Secure and Compliant?

Continuous Security & Reliability w/CD

• Automate log monitoring with tools like Splunk:– Monitor log stream data in real time – Detect a breach that is currently happening– Conduct a conclusive root-cause investigation following a breach– Detect a breach has already occurred

• DevOps Audit Defense Toolkit is compliance model for regulated industries– Code Reviews– Automated Testing during CI/CD– Dynamic Analysis (evaluation during runtime)– Full Traceability (RqmntsCodeTestingDeployment)– All changes to code and infrastructure go through the same

automated, auditable Continuous Delivery Pipeline18
