Traditional AppSec techniques such as testing, scanning, and code reviews are essential but often unable to protect against zero-day vulnerabilities before they are discovered and disclosed. In this talk, we will explore how Runtime Application Self-Protection (RASP) technologies can provide real-time behavioral monitoring and protection for applications during execution. We will dive into the limitations of pre-deployment security and explain why runtime protection is necessary. Furthermore, we will discuss the main components and architecture of a RASP solution, highlighting its key features and benefits. Attendees will gain insights into various RASP techniques, including behavioral analysis, anomaly detection, and machine learning, which are crucial for detecting unknown threats. Real-world examples of RASP preventing zero-day exploits and unknown attacks will be shared, showcasing its effectiveness in safeguarding applications. Lastly, we will provide best practices for implementing and integrating RASP into the CI/CD pipeline and DevOps workflow.
