Summary

In this chapter on data security, we discussed five layers of data security that are crucial for protecting sensitive data. These layers are data protection, access control, authentication, network security, and threat protection.

We covered data protection, which involved implementing data encryption at rest and data encryption in transit. We also discussed access control, which involved controlling who had permission to access data. We explained various access control mechanisms, such as RBAC, SASs, RLS, CLS, OLS, and dynamic data masking. These mechanisms ensure that only authorized users can access specific data based on their roles or permissions.

Authentication is another important layer of data security that we covered. We emphasized the use of strong passwords, MFA, and firewall rules to prevent unauthorized access. Strong passwords and MFA help enhance security by requiring users to provide additional proof of their identity beyond just a password. Firewall rules...
