1 Encrypt your data

One of the most effective ways to protect your data is to encrypt it. Encryption is the process of transforming data into a form that is unreadable by anyone who does not have the key to decrypt it. Encryption can be applied to data at rest (stored on disks or backups) or data in transit (moving between servers or clients). By encrypting your data, you can prevent unauthorized users from accessing or tampering with it, even if they manage to bypass your network or physical security. You can use various encryption methods, such as symmetric, asymmetric, or hybrid encryption, depending on your needs and preferences. You should also use secure protocols, such as SSL or TLS, to encrypt the communication between your database and your applications.

1. Enforce Multi Factor Authentication in your system. 2. Provide least access to any user. Avoid any sysadmin/database owner access. 3. Encryption at rest. 4. Don't use default port number instead use custom port number and Disabled the SQL Server Browser services. 5. Your organization should use strong Group polcies at the OS level and Any group policiies which would remove any unneccessary local admin accounts. 6. If Databases are at Cloud, SG level and NACL should block most of the ports until we need that. 7. Monitor and Audit Database Activities. 8. Regularly backup the database. 9. Regular Security Assessments 10. There should be a stringent Audit process.

2 Implement access control

Another important way to protect your data is to implement access control. Access control is the process of granting or denying permissions to users or groups based on their roles, responsibilities, or identities. Access control can help you limit the exposure of your data to only those who need it for legitimate purposes, and prevent unauthorized or malicious users from accessing or modifying it. You can use various access control models, such as discretionary, mandatory, or role-based access control, depending on your requirements and policies. You should also enforce strong authentication and authorization mechanisms, such as passwords, tokens, or certificates, to verify the identity and privileges of your users.

If you have application user interfaces that enable users interact with the database, ensure that input validation on form fields are enforced and active to avoid SQL injection attacks.
