Many large organizations have had their database system hacked and customer data stolen. How should the security for the database be different than security for the rest of the system? Does it make a difference for web-based data designs? If so, how?
What will be an ideal response?
Database security should be part of overall system security. But there are specific actions a DBA can take to further secure the database. For example, the DBA can define authorization procedures to ensure that only legitimate users can access the database and can allow different users to have different levels of access. Most DBMSs provide sophisticated security support.
Encrypting sensitive data in the DBMS provides additional protection. For example, Personally identifiable information (PII), data that could potentially identify a specific individual, should be encrypted.
Web-based data designs require end-to-end encryption of network traffic, secure connections with proper security certificates, and mechanisms in place to safeguard customer data stored on the server or in the cloud.
