Transitioning applications and data from in-house servers to cloud-based solutions like Azure promises many benefits, but the process is not without its perils, especially regarding cybersecurity. This blog post focuses on effective strategies to ensure a secure 'migration from on premise to Azure'. From outlining the steps of a secure transfer process, to the specific tools that Azure offers for improved security, we hope that this guide will be your reliable assistant.

Introduction

Migration from on premise to Azure requires careful planning and implementation to maintain data integrity and security. It is vital to adopt a holistic approach that incorporates a secure architecture design, identity and access management, constant monitoring, management of data, and threat protection.

Solidifying the Foundation: Secure Architecture Design

Creating a secure architectural design serves as the foundation for a smooth migration from on premise to Azure. Microsoft provides an Azure Security Benchmark to guide you through the process. This security measure promotes globally applied security and compliance controls. Make sure to include Azure Security Center and Azure Policy in your blueprint to bolster security and governance standards.

Identity and Access Management

Identity is the new security perimeter in our digital world. The Azure Active Directory (Azure AD) serves as the initial barricade that shields enterprises from unauthorized access. You can regulate control over the users and groups that tap into your resources using role-based access control (RBAC). Furthermore, Azure AD Conditional Access allows for the configuration of policies that permit or deny access attempts based on assigned conditions.

Consistent Monitoring

Consistent monitoring is crucial in detecting and responding to suspicious activity promptly. Azure offers a range of tools like Azure Monitor and Azure Security Center for comprehensive tracking. Azure Monitor collects, analyzes, and acts on telemetry data from your cloud and on-premises environments. Meanwhile, Azure Security Center bolsters the detection capacity rendering a birds-eye view for security posture management and threat protection.

Data Management and Protection

The strategic management and protection of data play a critical role during migration from on-premise to Azure. This strategy can be executed by utilizing Azure Backup for automatic backup, and Azure Site Recovery for disaster recovery. Azure Information Protection helps classify and protect documents and emails, and Azure Advanced Threat Protection helps detect and investigate advanced attacks on-premise and in the cloud.

Threat Protection

Prevention is better than cure, particularly in terms of cybersecurity. With Advanced Threat Protection (ATP) on Azure, you can detect and respond to potential threats before they hit. Azure ATP, Azure Firewall, and Azure DDoS protection offer a trifecta of threat protection strategies designed to safeguard the perimeters from attacks and immediately alert you to suspicious activity.

Conclusion

In conclusion, securing a smooth transition during migration from on premise to Azure requires meticulous planning and a multi-faceted approach. A secure architecture design, careful management and protection of data, vigilant monitoring and efficient threat protection are essential strategies in this process. By effectively using the tools and features that Azure provides, one can ensure not only a seamless migration but also a secure cloud environment, contributing to the resilience and success of the organisation.
