Linus’s Law, named after Linux creator Linus Torvalds, postulates that open code leads to more effective bug detection because when an entire community is scouring through code, fixes come more quickly. This is often the first thing IT pros consider when installing security inside an open-source model. Through popular code-and tool-sharing sites like GitHub, the open-source community aids other organizations in securing their own code and systems, offering a list of free security tools and frameworks for malware analysis, penetration testing and other tasks. Along these same lines, a recent report from the Ponemon Institute explored how IT professionals view commercial open-source software, data protection, and the security impact of messaging and collaboration solutions on their organizations. This slide show, based on eWEEK reporting and industry insight from Olivier Thierry, chief marketing officer of Zimbra, offers eight takeaways to help your business harness the value of open source and get serious about security.
