Use Azure Key Vault to Keep Your Data Safe

Key Vault Introduction

Azure Key Vault is a cloud-based service offered by Microsoft Azure that helps you securely manage and protect sensitive information such as keys, secrets, and certificates used by your applications and services.

Reason to use Key Vaults

  • Robust Authentication and Authorization with Azure Active Directory and Azure RBAC: Azure Key Vault ensures proper authentication and authorization mechanisms by seamlessly integrating with Azure Active Directory (Azure AD) and Azure Role-Based Access Control (RBAC). This ensures that only authorized users and services can access and manage keys, secrets, and certificates.
  • Enhanced Security
  • Effortless Administration and High Availability
  • Comprehensive Monitoring with Logging
  • Seamless Integration with Other Azure Services

Azure Key Vault Works?

  • Key Vault provides secure storage of generic secrets, such as passwords and database connection string
  • Importantly, this encryption process operates seamlessly without any user intervention. When you add secrets to Azure Key Vault, the service automatically encrypts them, and likewise, it handles the decryption process transparently when you retrieve them.”s.
  • Key Vault accepts data, encrypts it, stores and manages secrets as sequences of octets (8-bit bytes), and returns a secret identifier (id). The identifier can be used to retrieve the secret at a later time.
