“Zero Trust Architecture: How Ledger, Always Encrypted, & AAD Support in Azure SQL DB Can Help Keep Your Data Secure”

Why Ledger, Always Encrypted, & AAD Support in Azure SQL DB are Vital for Zero Trust Architecture
Introduction
Nowadays, organizations are looking for ways to improve their security posture and keep their data secure. With the increasing threats from cyber-attacks, organizations are turning to Zero Trust architectures to ensure their data is protected. In a Zero Trust architecture, all data is encrypted, and access is restricted to authorized users. Microsoft Azure SQL Database (Azure SQL DB) is a cloud database platform that provides a secure environment for storing and managing data. In this article, we will discuss why ledger, Always Encrypted, and Azure Active Directory (AAD) support in Azure SQL DB are vital for Zero Trust architectures.

What is Ledger?
Ledger is a database technology that stores data in an immutable chain of records, called blocks. It is a distributed database, meaning that multiple copies of the ledger exist in different places, and each update to the ledger is replicated across all the copies. This ensures that the data is accurate, secure, and up-to-date. Ledger is used in applications such as cryptocurrency, distributed ledgers, and smart contracts.

What is Always Encrypted?
Azure SQL DB supports Always Encrypted, a feature that encrypts data both in transit and at rest. Whenever data is stored in a database, it is encrypted using a key that is known only to the user. This ensures that the data is secure and cannot be accessed by anyone without the key. In addition, when data is transmitted between the user and the database, it is also encrypted, preventing any potential eavesdroppers from accessing the data.

What is Azure Active Directory (AAD)?
Azure Active Directory (AAD) is a cloud-based identity and access management service. It provides users with secure access to applications and data within an organization. AAD uses multi-factor authentication to ensure that only authorized users can access data. It also provides role-based access control, which ensures that users can only access the data they are authorized to access.

How Are Ledger, Always Encrypted, & AAD Support in Azure SQL DB Vital for Zero Trust Architecture?
In a Zero Trust architecture, all data is encrypted, and access is restricted to authorized users. Ledger, Always Encrypted, and AAD support in Azure SQL DB are vital for Zero Trust architectures because they provide the security and encryption needed to protect data. The ledger technology ensures that data is stored in an immutable chain of records, while Always Encrypted ensures that data is encrypted both in transit and at rest. AAD provides secure access to applications and data within an organization and ensures that only authorized users can access data.

Conclusion
Ledger, Always Encrypted, and AAD support in Azure SQL DB are vital for Zero Trust architectures because they provide the security and encryption needed to protect data. Ledger ensures that data is stored in an immutable chain of records, while Always Encrypted ensures that data is encrypted both in transit and at rest. AAD provides secure access to applications and data within an organization and ensures that only authorized users can access data. By implementing these technologies, organizations can ensure their data is secure and protected from cyber-attacks.
