In 2021, JFrog extensively covered DevSecOps topics in response to the growing importance of security in software development, culminating in a "Best of 2021" post highlighting key insights and discoveries. The blog series addressed new vulnerabilities identified by JFrog's security research team, such as malicious packages in PyPI and npm repositories, and explored significant issues like the log4j vulnerability and the critical role of the Software Bill of Materials (SBOM) in securing the Software Development Life Cycle (SDLC). It offered practical advice on evaluating DevSecOps products, protecting against supply chain attacks, and improving vulnerability disclosure processes. Additionally, JFrog shared detailed analyses of specific security threats like the INFRA:HALT vulnerabilities in NicheStack and provided guides on using tools like Xray for software composition analysis and Artifactory in air-gapped environments.
