Improved Data Security
A DBMS acts as the middleman between databases and users. The more often we need to access a database, the higher the risk of a security breach. With a DBMS, we can implement security policies that define permissions regarding who can access what and where data is allowed to be stored. A DBMS allows us to have strict control over the data’s journey within our system.
Privacy Compliance
A DBMS provides a framework for compliance with privacy policies, which allows companies to manage privacy and security in a centralized manner. Privacy compliance is all about using data responsibly, whereas data security is simply about protecting all our data from malicious threats. Ultimately data privacy comes down to following regulations to clearly establish what data is protected, how it’s protected, from whom it’s protected and who is responsible for that protection.
