Study Notes
DevSecOps: Ensuring Security in DevOps World
- Application security has evolved with the industry's shift to DevOps, integrating itself across the three "ways" to ensure high-quality software.
- Security has adapted to work alongside development and operations, adding security checks to the pipeline and breaking activities into smaller, faster chunks.
- DevSecOps refers to integrating security into the three ways, conducting application security within a DevOps context.
- Five strategies for building a DevSecOps pipeline include using unit tests as a weapon, ensuring the safety of third-party components, auditing system and settings, conducting dynamic application security testing, and including static application security testing in the workflow.
- Third-party components now make up over half of all code in applications, and 26% of those components have known vulnerabilities.
- MITRE developed the Common Vulnerability Enumerator database (CVE), and the US government created the National Vulnerability Database (NVD), both containing a list of all officially known vulnerabilities.
- Containers are standardized software components that wrap up code and its dependencies, ensuring applications run consistently in different environments.
- Verifying the state of server patches, configuration, encryption status, and security headers is crucial to ensuring a secure deployment.
- Dynamic application security testing (DAST) involves conducting scripted assaults and fuzzing against the application, and should be run in a parallel security pipeline or after hours.
- Static application security testing (SAST) tools are slow, expensive, and have a high false positive rate, but can potentially eliminate entire bug classes if fine-tuned.
- DevSecOps is about culture and shared accountability, aiming to deploy better software more quickly and to discover and respond to software issues in production more efficiently.
- DevSecOps is important in the DevOps cycle, ensuring seamless integration of security testing and protection throughout the software development and deployment lifecycle.
Test your knowledge of DevSecOps and its role in ensuring security in the DevOps world with this quiz. Explore strategies for integrating security into the development and operations processes, and learn about key concepts such as unit tests, third-party component safety, application security testing, containerization, vulnerability databases, and more.
