Over 1 billion entrepreneurs are using Microsoft Azure worldwide, and the number is constantly increasing. However, significant power or advantage comes with great responsibility, especially when it comes to protecting sensitive information stored in the cloud.

As technologies evolve, so do the threats to data security. Cybercriminals constantly refine their tactics, making it imperative for businesses to fortify their defenses. So, how to combat with such activities? This blog will help!

Here, we will explore essential Microsoft Azure security best practices to establish the safety of data stored in the cloud.

What is Azure Security?

Azure security refers to the native security components and tools that provide threat protection to cloud workloads. This is designed to safeguard data, applications, and infrastructure hosted on the Azure platform. The system will automatically alert you in case of concerns and ensure double security.

Importance of Azure Security

Below are some of the core reasons describing the importance of Azure security.

Establish a Strong Foundation

Azure prioritizes security as a fundamental building block and implements multiple layers of protection across its infrastructure.
The platform employs specialized hardware and sophisticated controls to defend against various threats, including complex ones like DDoS attacks.
A dedicated team of over 3,500 global cybersecurity experts continuously works to ensure data integrity and security within Azure.

Streamlined Security Measures

This cloud platform provides tools and services that simplify the process of securing digital assets, encompassing areas such as identity, data, and applications.
The best part is Microsoft Defender for Cloud offers continuous monitoring and protection.
Azure’s security features can be seamlessly integrated with various security solutions.

Proactive Threat Detection

Azure uses advanced intelligence capabilities and real-time global cybersecurity insights to detect emerging threats promptly.
With this proactive approach, Azure identifies and mitigates potential security risks before they escalate.

Best Practices for Azure Cloud Security

Identity and Access Management (IAM)

IAM solutions are said to be the foundation of cloud security. These use the principle of least privilege using Role-Based Access Control (RBAC) to limit user access to only what is necessary. In Azure, the cloud-native IAM service is known as Microsoft Entra ID.

We also suggest you implement Multi-Factor Authentication (MFA).

Why? Because it adds an extra security layer beyond just a password.

This typically involves verifying a user’s identity through a combination of something they know (password) and something they have (such as a mobile app or a text message with a code). Ultimately, it reduces the risk of unauthorized access, even if passwords are compromised.

Database Encryption

Data is the backbone of the cloud, and protecting it at any cost should be the fundamental priority for every business. But how to do it? Here we have got the answer.

Implement Restriction for Databases and Storage

Use firewalls and access controls to restrict user access to databases and storage blobs in Azure.
Implement measures that limit the level of access granted to individuals, machines, and services.

Auditing for Database Visibility

Enable auditing for Azure databases to gain visibility into all database updates.
This practice provides a comprehensive view of activities within databases, aiding in monitoring and security analysis.

Azure SQL Threat Detection

Activate Azure SQL’s threat detection feature to identify and mitigate potential security risks promptly.
This proactive approach helps reduce dwell time and enhance the overall security posture of Azure SQL databases.

Leverage Azure Security Center Services

The next best practice for securing cloud storage is the Azure Security Center. Here’s how to make the most of it!

Get Notified with Admin Security Alerts

Turn on Admin Security Alerts.
This means the Security Center will message you when something goes wrong with your Azure subscription.

Keep an Eye on Security Configurations

Enable Security Configuration Monitoring.
This feature ensures the Azure Security Center always watches your virtual machine activities.

Consistent Security Across Environments

Apply security rules everywhere – the Security Center lets you enforce security policies consistently across subscriptions, management groups, or tenants.

Keep an Eye on Activity Log Notifications

Activity logs act as your system’s early warning system, which identifies potential threats before they escalate. To ensure a proactive response, it is imperative to configure these alerts.

These alerts must adhere to Azure Security’s best practices during the setup process. You can establish a robust defense mechanism by closely monitoring alterations in your security solution and policy assignments.

Important: Stay informed about any deletions or adjustments to the Network Security Group. Keep a watchful eye on modifications to the firewall and its regulations.

Implement Layered Security

Implementing a layered security approach helps in security control at various levels of your system architecture. This is also known as defense-in-depth, where each layer serves as an additional line of defense and the risk of a single point of failure.

Network Security Layer

To fortify your network defenses, use a combination of services like Azure Firewall, network security groups, and Distributed Denial of Service (DDoS) protection.
By using multiple security services, you create a robust shield against potential threats at the network level.

Data Layer Security

Ensure your data security both at rest and in transit by implementing encryption and certificates.

Application Layer Security

Consider additional measures such as API management and web application firewalls (WAFs) to protect your applications from various vulnerabilities and attacks.

Threat Detection and Prevention Layer

Microsoft Defender for Cloud, Azure Advanced Threat Protection, and Microsoft Sentinel actively detect and prevent security threats. How? These services analyze patterns, behaviors, and anomalies to identify potential security incidents and enable proactive response.

Protect Secrets and Keys Using Key Vault

Azure offers Key Vault, a dedicated service for securely storing and accessing secrets, passwords, certificates, and cryptographic keys. It eliminates the need for developers to hardcode security credentials or database connection strings directly into their code.

Data stored in Key Vault is safeguarded against unauthorized access, including from Microsoft itself. This ensures confidentiality and sensitive data remains protected at all times.

Further, Key Vault can be seamlessly integrated with various Azure services, including

Azure Disk Encryption
Azure SQL Transparent Data Encryption and
Azure App Service.

This integration streamlines the process of securing sensitive data across different Azure offerings.

Microsoft Defender For Endpoint

Azure Security Center integrates with Microsoft Defender for Endpoint to offer extended detection and response capabilities. This service is available for both Windows and Linux servers to safeguard workloads against various threats.

If the organizations want, they can also create custom detection rules according to their specific security requirements.

Microsoft Defender regulates access to and from malicious sources, protecting the network and web layers from potential threats. This proactive approach helps prevent prohibited access and mitigate the risk of cyberattacks.

Network Security Groups (NSGs)

NSGs play a vital role in Azure security by filtering network traffic between resources within Azure virtual networks (VNets).

But how do NSGs work? They consist of security rules that dictate which traffic is permitted or denied for each Azure resource. All Azure services, including VMs, Azure Containers, and Azure Functions, can be deployed within a VNet to strengthen security.

You can follow the below tips to use NSGs for enhanced security.

Establish and configure a Default Security Group to block all traffic by default.
By doing so, the newly created security group lacking specific configurations will automatically deny all traffic.

Azure Cloud Security Checklist

Here’s a checklist for auditing security measures in Azure.

Azure Security Center

Enable Azure Security Center and review security recommendations regularly.
Implement Just-In-Time (JIT) access for restricting temporary access to specific ports.
Utilize adaptive application controls to define and enforce permitted application behaviors.

Azure Compliance

Identify relevant compliance laws and guidelines applicable to your business, like GDPR, HIPAA, PCI DSS, or ISO 27001.
Do what Azure suggests to keep data safe and check regularly to ensure ongoing compliance.

Azure Identity and Access Management (IAM)
