Continuous Integration and Continuous Deployment (CI/CD) pipelines are the backbone of modern software development, enabling efficient and reliable application delivery. However, as these pipelines become more integral to our workflows, they also present significant security challenges. Without proper safeguards, vulnerabilities within CI/CD systems can serve as entry points for supply chain attacks and other exploits. This session delves into best practices for fortifying CI/CD pipelines, drawing on real-world incidents to illustrate common pitfalls and the tactics employed by malicious actors. Attendees will gain actionable insights to identify and address vulnerabilities, ensuring their CI/CD processes are both secure and resilient against emerging threats.
