My security

My database security denotes the system, processes, and procedures that protect a database from unintended activity.
My security is usually enforced through access control, auditing, and encryption.
Access control ensures and restricts who can connect and what can be done to the database.
Auditing logs what action or change has been performed, when and by who.
Encryption: Since security has become a major issue in recent years, many commercial database vendors provide built-in encryption mechanism. Data is encoded natively into the tables and deciphered "on the fly" when a query comes in. Connections can also be secured and encrypted if required using DSA, MD5, SSL or legacy encryption standard.
