Cloud Vulnerability Defense with Microsoft Azure Fundamentals

Microsoft Azure is a digital platform that helps customers build and run their organizations. The fundamentals of Azure is it is one of the largest cloud service providers and aims to help its customers be secure from the beginning and to do more with the security of its cloud platforms, which are built-in and embedded. This is particularly important in a world with persistent, sophisticated, and driven cybercriminals, where trust is crucial and risks and threats are increasing. By building trust, Microsoft Azure hopes to help its customers protect their organizations, people, and data for a more secure future, while also satisfying complex compliance regulations.

Microsoft Azure has implemented a security strategy that includes multiple layers of protection throughout all stages of the design, development, and deployment of their platforms and technologies. This approach is known as defense in depth. In addition, Microsoft Azure is transparent about its efforts to continually learn and improve its offerings in order to protect against current and future cyber threats.

Fundamentals of Azure: Learning and improvements for a more secure cloud

Microsoft is committed to ensuring the security of its platforms and products and has a history of implementing best practices in security, including the Security Development Lifecycle (SDL) framework and a comprehensive bug bounty program. The company also invests heavily in internal security research and threat intelligence and works to improve the security posture of open-source software. In addition, Microsoft collaborates with other organizations in the security ecosystem and has committed to investing over $20 billion in cybersecurity over the next five years. To further secure its platforms, the company performs root cause analysis and post-incident reviews for every reported vulnerability in Azure, in order to reflect and apply lessons learned.

They are focused on improving its security measures in three key areas. These include improving their response process, expanding their internal security research, and continuously working to secure multitenant services. They have learned from recent reports of vulnerabilities in Azure and are using these insights to make changes to their security practices.

1. Fundamentals of Azure: Integrated response

Microsoft is looking to improve its response to vulnerabilities in fundamentals of Azure by accelerating response timelines, increasing the frequency and scope of its security live site reviews, and improving the integration of its external security case management and internal incident communication and management systems. These changes aim to reduce the mean time to engagement and remediation of reported vulnerabilities and improve rapid response. Microsoft is also expanding its internal security research and will be using more artificial intelligence and machine learning to help identify and mitigate threats. Finally, the company is working to improve the security of its multitenant services by implementing stronger security controls and better incident management processes.

2. Cloud Variant Hunting

They are implementing changes to improve their response process for reported vulnerabilities in fundamentals of Azure, including increasing the frequency and scope of their Security LiveSite Reviews and improving the integration of their external security case management and internal incident communication systems. They have also expanded their variant hunting program to include a dedicated Cloud Variant Hunting function to identify similar vulnerabilities across other services and understand vulnerability patterns in order to drive holistic mitigations and fixes:

• In Azure Automation they identified variants and fixed more than two dozen unique issues.
• In Azure Data Factory/Synapse they identified significant design improvements that further harden the service and address variants. They also worked with our supplier, and other cloud providers, to ensure that risks were addressed more broadly.
• In Azure Open Management Infrastructure they identified multiple variants, their researchers published CVE-2022-29149 and they drove the creation of Automatic Extension Upgrade capabilities to reduce time to remediate for customers. Their Automatic Extension Upgrade feature is already benefiting Azure Log Analytics, Azure Diagnostics, and Azure Desired State Configuration, customers.

Cloud Variant Hunting actively searches for and addresses potential issues in all of our services. This includes identifying and fixing a wide range of vulnerabilities, both known and unknown. In the future, they plan to share more information about their research with their customers and the wider community to improve the security of their services.

3. Secure multitenancy

They are constantly updating their Secure Multitenancy requirements and automation processes at Microsoft to detect and address potential security risks. Their internal and external security researchers have identified ways to breach isolation barriers in fundamentals of Azure and other cloud platforms. In response, they have invested heavily in proactive security measures to prevent these types of issues. By analyzing these cases and determining the most common causes, they are able to make targeted changes to Azure to improve its security.

To further strengthen their defense-in-depth strategy, they are implementing even more stringent standards for isolating Compute, Network, and Credential resources across all Azure services, particularly when using third-party or open-source software components. Microsoft also works with the open-source community, including PostgreSQL, and other cloud providers to develop features that are specifically designed for multitenant cloud environments.

So far, this effort has resulted in a large number of findings and fixes, with the majority (86%) related to improving Compute, Network, or Credential isolation. To further improve automation, we are expanding our internal Dynamic Application Security Tests (DAST) to include more checks for validating Compute and Network isolation and adding new runtime Credential isolation check capabilities. At the same time, our security experts are carefully examining our cloud services to ensure that they meet our standards and developing new automated controls for the benefit of our customers and Microsoft.
