Oracle 11g facilitates user by providing “Defense-in-Depth” type of security. It supports both protective as well as detective type control of security. The widely categorized area are Monitoring and Blocking, Auditing and tracking, Encryption and Masking and Access Control. Whereas MySQL 5.1 uses security based on Access Control Lists (ACLs) for all connections, queries, and other operations that users can attempt to perform. Similarly while in case of SQL Server 2012 which is built upon Kerberos authentication, Extensible key management and transparent data encryption. Oracle manages the encryption key transparency with two-tier key architecture. Oracle gives strong encryption solutions to protect sensitive data from unauthorized access via the operating system or backup media, Whereas SQL Server Controls database access to installed applications while improving manageability through Contained Database Authentication. SQL Server 2012 Follows Extensible Key Management using the latest encryption standard AES256. In the versions prior to MySQL 4.1, encryption algorithm is not very strong as compared to current algorithm used in MySQL 5.5.Oracle Advanced Security Transparent Data Encryption (TDE) facilitates to manage privacy and regulatory requirements through Encrypting personally identifiable information (PII) such as passport number, PAN number and financial information such as debit card numbers, credit card numbers, Bank account numbers.
