Encryption converts the data into unreadable form for unauthorized people.

SSL certificates are critical for ensuring the security of data transmitted from websites and applications. These certificates on the server, which authenticate the server identity and enables an encrypted connection so no one can eavesdrop.

Equally important is the application of Role Based Access Control (RBAC). RBAC limits availability to resources and data according to a user's designated role within a company. Only authenticated users can cross check certain data, hence the risk of data breaches and unauthorized changes are mitigated.
