Interest is growing in open source databases, in part due to security concerns. Evans Data surveyed 400 industry database administrators and found that use of the open source database software MySQL increased over 25% in six months and 44% of developers are now using it. Respondents said security was an important part of database development. Only 9% of those using open source reported a security breach within the last year, but 85% said proprietary database server data was compromised at least once in the last year. This situation may be similar to that of Firefox, which was relatively immune to attack until it gained enough users to draw the attention of both vulnerability researchers and hackers. Some believe the open source community can respond more quickly to vulnerabilities than can developers of proprietary software, but only time will tell if such is the case.
