Shifting security and license compliance checks to the earliest stages of the software development lifecycle, known as "Shifting Left," is advocated to ensure adherence to security policies and standards. The JFrog CLI simplifies this process by allowing developers to scan dependencies directly from local sources with ease, providing detailed violation reports. Setting up the JFrog Platform and CLI is quick and can be accomplished through simple commands on various operating systems, including Mac, Linux, and Windows. The CLI supports multiple security scan commands, such as auditing project dependencies, scanning Docker images, and conducting on-demand binary scans, which return comprehensive security reports. These tools enable developers to address vulnerabilities early in development, preventing issues post-compilation, and the open-source nature of the JFrog CLI allows for further customization and plugin development.
