This chapter will outline the importance of protecting secrets. Before diving deeper into Azure Key Vault, it is vitally important that one recognizes this aspect.
Application Secrets: What Are They? (Application Secrets)
Application secrets often remain unseen but play an integral part in modern software systems. Ranging from sensitive data protection measures, these secrets play a pivotal role in protecting vital resources.
Take a look at some of the more frequently occurring types of application secrets.
API Keys
API keys serve as digital passports that grant applications access to APIs or external services, acting as gateways for fetching data, sending requests and performing secure operations.
Passwords
Passwords are one of the primary forms of digital authentication and should protect user accounts, administrative functions and system components.
Any leakage of passwords could result in data breaches and unwarranted access.
Database Connection Strings
Database connection strings form the core of all data-driven apps and contain information necessary for connecting with databases - server addresses, authentication credentials and encryption keys are just some examples of essential pieces of information that make up these strings.
Certificates
Both SSL/TLS certificates and digital certificates ensure secure communication between parties. These certificates verify the identity of clients and servers, protecting against man-in -the -middle attacks.
Encryption Keys
Encryption keys play an essential part in safeguarding data both during its transit and at rest, acting as integral elements in cryptographic operations such as encryption/decryption to ensure data confidentiality.
Databases, cloud services and third-party APIs hold the keys to unlocking any security code or information system.
Misuse or exposure of these secrets could result in serious repercussions: data breaching, financial losses and irreparable harm done to an organization's reputation.

Azure Key Vault Is A Key Vault.
Azure Key Vault allows users to securely manage, store and safeguard sensitive data such as keys, passwords and certificates in one centralized location protected with industry standard algorithms and hardware security modules.
As many developers make this mistake, leaving sensitive information such as passwords and connection strings for databases in source code could have serious repercussions if someone accesses them illegally.
RBAC allows administrators to control who can gain entry to such vaults storing sensitive material.
Azure Key Vault Addresses The Following Issues:
Secrets management - Azure Key Vault can be used to securely store, manage, and access tokens, credentials, certificates, API key, and any other secret.
Certificate management - Azure Key Vault includes a certificate manager which simplifies enrollment, management, and deployment of public and private certificates for use with Azure or any resources connected.
There are two service levels within Azure Key Vault: Standard which uses software-based keys while Premium includes keys secured using hardware security modules (HSMs).
Why Use Azure Key Vault?
Centralize Application Secrets
Azure Key Vault makes it possible to control and protect application secrets more securely by significantly decreasing their risk of accidental disclosure.
Key Vault provides developing Microsoft Azure and web services with an effective means of eliminating the necessity to include security information as part of the code base for their apps.
By not storing such sensitive details inside apps, developers no longer must include such code into their programs to maintain this aspect of security.
An application requires accessing data securely stored within the Key Vault database. Your applications will then access data using URL URIs without fear of disruption from key Vault's encryption technology.
Store Secrets And Keys Securely
Before access can be granted to the key vault, users must authenticate and authorize themselves. Authorization grants them permission for certain operations while authentication confirms their identity.
Azure Active Directory can be used as the foundation for authentication, with Role Based Access Control (RBAC) or Key Vault Access Policies being employed as authentication measures and for authorizing users or data access attempts respectively.
Azure RBAC may also be utilized in vault administration while Key Vault Policies serve to attempt accessing vault data.
Azure Key Vaults offer both hardware and software protection options to meet varying security needs. Azure uses industry standard procedures for software-protected secrets and certificates; for additional safety you may create or import keys that never leave an HSM.
Monitoring Access And Usage
You'll need to track how your secrets and keys are used after you have set up Key Vaults. You can track what is happening by activating the logging feature for your vaults.
Azure Key Vault is configured in a number of ways.
- Archives to storage accounts
- You can stream to an event hub
- Logs sent to Azure Monitor
Your logs are under your control. You can protect them by restricting their access or deleting records no longer required.
Simple Administration Of Application Secret
Security information must be accessible, safe and have a long lifecycle. Azure Key Vault helps you meet these needs because it is easy to use.
- No longer is it necessary to know the Hardware Security Modules in-house
- Short notice scaling up is required to increase your organization's usage.
- Your Key Vault contents are copied to another region as well as within the region.
- The replication of data ensures that the system is always available and does not require the administrator to do anything to start the failover.
- Azure Management options can be accessed through PowerShell, Azure CLI and the standard interface.
- Automating the enrollment and renewal of public CA certificates can automate a number of tasks.
Integrate Other Azure Services
Azure has used Key Vault as a secure storage solution to simplify scenarios like:

Important Ideas In Azure Key Vault
Key Vault Is Referred To By The Following Terms:
Tenant: A tenant is an organization who owns, manages, and uses a particular instance of Microsoft Cloud Services.
Most commonly, it's used to describe an organization's Azure or Microsoft 365 services.
Key Vault Owner: The vault owner has full control over the key vault. The vault owner can set up auditing to track who has access.
Administrators can manage the key's lifecycle. Administrators can perform various operations, including restoring the key to an updated version and backing it up.
Consumer: The consumer has access to all assets in the vault when the owner of the vault grants it.
Permissions determine the actions that are available.
Managed Pool Administrators: Managed pools are completely controlled by users assigned to the Administrator role.
The Administrators can assign more roles to other users in order to regulate their access.
Managed HSM Encryption Service: Built-in role is typically assigned to service principals or users who use keys to perform cryptographic operations in Managed HSM.
Users of cryptography can create new keys, but cannot delete the existing ones.
Resource: A resource can be managed by Azure.
Resource group: A resource container is an Azure solution that contains connected resources.
Resource groups can be created to contain the entire solution, or only the resources you wish to group together. The resource group is assigned based on the best fit for your company.
Security principle: Access to specific Azure resources is governed by the Azure security principles.
Azure Active Directory: Azure AD provides Active Directory services to tenants. Each directory can have one or multiple domains.
Multiple subscriptions can be linked to a directory but there is only one tenant.
Azure TenantID: An Azure tenant ID can be used to uniquely identify an Azure AD subscription.
Managed Identity: Azure Key Vault lets you securely store keys, credentials and secrets.
However, you have to authenticate using Key Vault to access them. By providing Azure Services with an automatically managed Azure AD identity, a managed Identity makes it easy to fix this issue.
Azure Key Vault Use
Infrastructure provision on Azure is an established practice; virtual machines created in Azure often hold all our files - operating system data as well as application details - on disk.
Information stored on disc should always be encrypted so any unwelcome person won't be able to easily decipher and read what's stored there.
Azure provides an integrated key management platform. All disks are automatically encrypted; as customers, however, we have the freedom to provide our own encryption keys in order to encrypt or decrypt virtual drives as required.
Azure Key Vault can store disk encryption keys securely. Plus, Azure Key Vault may come in handy in many other scenarios as well.
If you want to connect a web app to SQL, enter its server address, username and password into its configuration file. Azure Key Vault can assist with the storage, protection and management of sensitive secrets.
In Azure, Create A Key Vault.
The following are different ways that an Azure key vault can be created.
Using Azure CLI
Azure Command-Line Interface is a tool that can be used to create a Key vault. You can use CLI by either installing it directly on your device, or using the cloud shell.
After you've installed the CLI on your device and signed in to Azure, follow these steps to create a key vault:
- Create a Resource Group with the command below: az group create --name "myResourceGroup" -l "EastUS"
It will create an EastUs resource group named myResourcegroup.
- Create a key vault in the Resource Group created at the previous step using the Azure CLI command keyvault create.
Please provide the following details:
Name of the key vault: A sequence between 3 and 24 characters, which can only contain numbers (0-9) letters (a-z A-Z) or hyphens ("-").
Resource Group name: myResourceGroup
EastUS Location: az keyvault create -name " " -resource-group "myResourceGroup" -location "EastUS"
This command will show the properties of your newly created vault. Note the properties below.
Vault name: This is the name that you have provided in the parameter -name above.
Vault URI: This is an example: https:// .vault.azure.net/. This URI must be used by applications that access your vault via its REST API.
