An interesting feature has been released to the SQL Azure Labs website, called SQL Azure Test Security Service. What it enables is you to assess the security state of one or all of the databases on your SQL Azure server. The service scans databases for security vulnerabilities and provides you a report. You can use the recommendations and best practices provided in the report to improve the security state of your databases.
Nice way to make your cloud solution even more secure. Go check it out, sign up on the site linked above.
