Background
Database encryption has been around for decades, but it has traditionally been a complex and challenging process to implement. Older encryption techniques require complex key management and can impact performance. Moreover, encryption is typically applied at the server level, making it vulnerable to insider attacks or unauthorized access by administrators.
SQL Server Always Encrypted was introduced in SQL Server 2016 as a response to these challenges. Always Encrypted uses client-side encryption to protect sensitive data stored in databases. With client-side encryption, data is encrypted on the client side before being sent to the server, so the server doesn’t have access to the unencrypted data.
Challenges and Opportunities
One of the most significant challenges of database encryption is balancing security with performance. Encryption can cause a significant impact on database performance, especially when dealing with large volumes of data. Always Encrypted addresses this challenge by using client-side encryption, which ensures that encryption and decryption are handled by the client, not the server.
Always Encrypted also presents a unique opportunity for businesses and organizations to secure sensitive data in a way that was previously difficult or impossible to achieve. For example, in the healthcare industry, Always Encrypted can be used to protect patient data stored in electronic health records (EHRs). Similarly, in the financial industry, Always Encrypted can be used to secure sensitive financial data such as credit card numbers, social security numbers, and bank account information.
Best Practices
Implementing Always Encrypted in SQL Server requires careful planning and execution. Here are some best practices to keep in mind:
Use the latest version of SQL Server: Always Encrypted was first introduced in SQL Server 2016, and subsequent versions have improved on the feature. Always use the latest version of SQL Server to take advantage of the latest security enhancements.
