- So let’s talk about security. As end users continue to demand access to data and corporate and industry compliance policies tighten, the topic of security becomes paramount. The security of your environment is only as good as the product you’re using, and amongst the major database players we have the best track record. SQL Server consistently reports the lowest database vulnerabilities among the major RDBMs vendors. This means less inherent security vulnerabilities, less patching and less downtime – all factors that affect Mission Critical Confidence. It looks too good to be true, right? If anyone experienced “SLAMMER” with Microsoft over 10 years ago, you know how painful a security risk can be – it took down the internet. In response, Microsoft started a journey to fundamentally embrace a security culture around Secure by design, depth of security and depth of defense, to reduce the overall surface area to minimize risk. All SQL Server engineers take required security trainings year over year. As a result, SQL Server is now the most secure database available. With SQL server 2012, we continue to expand on this solid foundation with tools and enhancements to help customers more easily control access to data and perform audits.
