Protecting Your Azure VMs: Best Security Practices for Business Success

The cloud has become an essential component of business operations, driving productivity, efficiency, and innovation. With the adoption of cloud technology, security concerns remain a top priority for organizations that store and use sensitive data on cloud platforms like Microsoft Azure. Azure provides a wide range of security features, and it’s up to businesses to ensure their configurations are secure.

Here are some best security practices to protect your Azure virtual machines (VMs):

1. Use Multifactor Authentication (MFA)

Multifactor Authentication is a security protocol that requires more than one form of authentication to grant access. It adds an additional layer of protection to your Azure account by requiring users to present both their password and something else—usually a code generated by their mobile device. This extra verification step ensures that only authorized users have access to your VMs.

2. Use Encryption

Encryption is the process of translating data into code or cipher so that unauthorized individuals cannot understand it. Implementing encryption when deploying Azure VMs increases security and safeguards the confidentiality of data. Azure provides native encryption services like Azure Disk Encryption, which encrypts OS and data disks and encrypts virtual machine files while in transit.

3. Monitor Activity Logs

Monitoring activity logs is a crucial part of enhancing security. It provides insights about who’s accessing your VMs, from where, and what actions they are performing. Azure provides a comprehensive suite of activity log tools to detect and respond to any suspicious behavior.

4. Use Network Security Groups (NSGs)

Network Security Groups help protect your VMs’ access by providing a set of firewall rules to allow or deny inbound and outbound traffic. Use NSGs to restrict access to the VMs to only authorized users, devices, or applications.

5. Choose Strong Passwords

Passwords that are easy to guess or crack are a potential vulnerability in your VMs’ security. It is good practice to enforce password policies that restrict users from using easily guessable passwords. Use strong passwords with a combination of upper- and lower-case letters, numbers, and special characters for all user accounts.

6. Use Azure Security Center

Azure Security Center is an Azure-native security solution that provides a centralized view of security posture and provides recommendations based on best practices. It helps you to detect threats and vulnerabilities, and provides the necessary actions to remediate them.


In today’s security environment, securing Azure VMs is crucial to protect sensitive information and business operations. This requires a thorough understanding of best security practices, regular monitoring and maintenance, and proper data management workflows. By implementing these practices, businesses can help prevent unauthorized access to their VMs and safeguard their data.
