While Azure is a powerful cloud computing platform that offers a wide range of cloud services, including networking, storage, and analytics, it comes with some security risks you should safeguard against. Failure to secure your Azure resources can result in unauthorized access to sensitive information and data leakage.
Your resources may also be exposed to network sniffing and DDoS attacks. Implementing the right preventive measures can help enhance your Azure environment’s security while protecting your valuable assets. Discussed below are four Azure security best practices.
1. Deploy the defense in depth strategy
Unauthenticated access and data breaches are among the common Azure security risks many organizations are likely to experience. The defense in depth security strategy deploys an intense environment with several security and validation layers, helping prevent data breaches while slowing down unauthorized attempts to access data.
Since this security approach is multi-layered, each layer offers protection such that if one of the layers is breached, the subsequent one is already in place to avoid further exposure. The defense in depth strategy eliminates dependence on any single protection layer. The following are the layers in the defense in depth mechanism:
- Physical security
- Identity and access
- Network
- Perimeter
- Access
- Compute
- Data
- Applications
2. Implement multi-factor authentication
Multi-factor authentication (MFA) requires numerous forms of authentication, adding an extra security layer to user accounts. Azure MFA adds an extra step to your login procedure to avoid unauthenticated access even if your password is compromised. Implementing the MFA Azure protocol offers several advantages, including:
- Improved security: MFA adds an extra verification layer beyond a password, minimizing the possibility of unauthorized access and safeguarding sensitive data your Azure resources
- Helps you meet compliance requirements: When it comes to protecting sensitive data, most industries must adhere to specific compliance requirements. Azure MFA provides an additional security layer that helps you meet these requirements
- User convenience: MFA supports several authentication techniques, including alerts from mobile applications, text messages, hardware tokens, and phone calls. This means you can pick a method that best suits your needs without compromising security
3. Enable the principle of least privilege and Azure privileged identity management (PIM)
When it comes to access control and permissions, Azure has its own challenges. This is where the principle of least privilege and PIM come in. The principle of least privilege:
- Safeguards sensitive data while reducing security breaches by allowing users the minimum number of permissions needed
- Helps your organization reduce the likelihood of malicious or accidental misuse of sensitive data in the event of a security breach.
Azure privileged identity management implements the principle of least management by managing user privilege elevation and restricting it to the minimum crucial for performing job functions, reducing the risk of unauthorized access and security breaches.
4. Establish a patch management process
Azure’s patch management comprises the procedures of updating the operating systems and software in the Azure environment. This technique is crucial for securing your cloud infrastructure. Delaying patch management exposes your Azure resources to potential security threats, resulting in data loss, breaches, and downtime. The longer you wait to install patches and updates, the longer you leave your Azure investment susceptible to vulnerabilities.
Applying patches and updates regularly guarantees your cloud environment’s optimal performance and security. It’s also important to implement updates at the earliest time possible to ensure your Azure environment runs optimally and securely. Patch management isn’t a one-time task. It’s an ongoing process vital for safeguarding your Azure environment.
5. Implement data encryption
Encryption involves encoding data to ensure only those with the decryption key can read it. It’s a vital security best practice as it helps safeguard your data against theft and unauthorized access. Azure provides strong encryption solutions for data in transit and at rest, which empowers you to protect your sensitive information. Encrypting data at rest focuses on securing information when it’s stored on digital and physical storage mediums, like cloud-based data repositories, hard drives, or solid-state drives. Encrypting data at rest offers numerous benefits, including:
- Protection from unauthorized access: Encrypting data at rest ensures even if people gain digital or physical access to your storage, they cannot read the information unless they have the decryption key
- Data resilience: It offers an extra protection layer against data loss because of data theft or hardware failures
- Compliance: Encrypting data at rest is usually a requirement by data protection laws, such as HIPAA and GDPR
Additionally, encrypting data in transit involves securing information while it’s being moved between two endpoints, ascertaining it stays confidential when in transmission. It offers several benefits, including:
- Data integrity: Encrypting data in transit helps maintain data integrity by ensuring information is received in the same way it was sent
- Secure communication: Data encryption in transit guarantees that information is protected during transmission. This makes it hard for eavesdroppers to tamper with or intercept the data
Effective data encryption allows you to confidently secure your information from unauthorized access while minimizing the possibility of data breaches.
6. Use key vault
Key vault is a basic security service offered by Azure and is crucial in securing sensitive data in the cloud. It aims to provide a secure, centralized repository for managing the digital certificates, secrets, and cryptographic keys used in services and applications. With Azure key vault, your company can securely keep, manage, and access cryptographic assets, reducing the likelihood of exposure and unauthenticated access to crucial data. Azure Key Vault’s significance lies in its capacity to address the challenges of managing cryptographic assets like connection strings and passwords, which are crucial for securing data and applications.
By allowing Azure key vault to manage cryptographic keys, your company can ensure sensitive information stays protected throughout its lifecycle. It’s made with sturdy security controls, access management, and encryption, complying with compliance standards and industry best practices. It allows in-depth access control, ensuring only authenticated applications and users can access particular cryptographic assets, reducing the risk of unauthorized access and insider threats.
7. Adopt a disaster recovery plan
Disaster recovery involves the technologies, methods, and practices companies use to restore IT and data access after technology-related disasters such as network outages, service disruptions, server failures, and security breaches. These disasters can be pretty costly for your business. This is where a disaster recovery plan or strategy comes in. It’s a document that directs your organization in the actions to take to mitigate while ensuring swift recovery in operations.
Azure site recovery (ASR) is a perfect solution for businesses looking for reliable, cost-effective disaster recovery as a service solution. With this approach, your business can safely keep and recover critical data in the cloud. Azure site recovery amplifies disaster recovery by reducing costs and time while promising successful failback and failover capabilities in case of a security threat. Its features app include:
- Customized disaster recovery: When it comes to ASR, a managed IT expert can design a fully customized disaster recovery strategy suitable for your requirements
- Workload replication: Azure site recovery smoothly moves your on-site applications and workloads to different secondary recovery sites, such as Azure’s virtual machines and physical servers. This solution ensures no crucial data is lost, regardless of whether you’re seeking remote or on-site management
- Service level management: ASR allows you to meet close to zero data loss to fulfill existing recovery point objectives, meaning there’s reduced data loss and downtime or service disruption
- Failback: ASR allows you to move back from the failover site to your primary environment without losing the changes made to your files or any data
