Open source software is often misunderstood, with several common myths surrounding its security. One misconception is that it's free, but licensing allows the true owner of the code to know who's using it and when changes are available. Despite concerns about security, open source has benefits such as rapid development, ease of deployment, and a community base for problem resolution. However, some myths persist, including that open source programs are less secure than proprietary software, that open source code integrity is questionable, and that open source is just a fad with security being an afterthought. In reality, the transparency provided by open source allows for thorough examinations of code, and many developers review and improve open source projects continuously. With cautious selection and evaluation, organizations can manage open source security risks and promote application security.
