One of the challenges in integrating AppSec for DevOps is the diverse and varied nature of DevOps pipelines and workflows. Different applications have distinct requirements, all of which impact security considerations. For instance, internal applications that operate within a protected internal server may not require the same level of security scrutiny as external-facing applications. You should consider mitigating factors and compensating controls when evaluating vulnerabilities to ensure that efforts are focused where they are most needed and most effective for the conditions.
Similarly, the purpose of the software also influences the prioritization of security measures. While internal applications may not directly generate revenue or interact with customers, they may still handle sensitive internal information. External applications, on the other hand, play a critical role in revenue generation and customer satisfaction, making them high-priority targets for security. Understanding the risk profiles of different types of applications helps allocate resources efficiently and prioritize security measures accordingly.
Lastly, the mechanisms used to develop and ship the software can determine the level of security risk insight a team can gather, how well it can address detected risks rapidly, and the type of risks present. Which development tools are teams using? How are code repositories configured? How do release cycles align to security testing workflows? These questions can prescribe your approach to application security testing and DevSecOps.
