Database infrastructure security is extremely crucial for any organization, which is why Microsoft has invested heavily in SQL Server security features in recent years. Microsoft redesigned the SQL Server database security engine from scratch for SQL Server 2005, and since then, SQL Server security has improved with each update.
Microsoft SQL Server 2012 continues this trend with an extensive collection of new security features and enhancements. These enhancements not only help organizations to improve access controls to data, but also to achieve the highest level of data protection and compliance. Also, these features help make SQL Server arguably the most robust common database platform from a security perspective, with less vulnerability and fewer security patches needed to maintain the system.
Checkout my article here that list all security enhancements which DBAs expect in SQL Server 2012.
