Partnering for Security: Qualys Solutions for Microsoft Azure Linux in AKS and Azure Container Instances

As customers transition from traditional workloads to containerized environments, they face significant challenges. Containers introduce a level of complexity that traditional security measures often fail to address, primarily due to their ephemeral nature and the shared responsibility model between the host OS and the container. The shift requires a reevaluation of security strategies, as visibility into containerized applications is more limited, and vulnerabilities can propagate rapidly across environments. Organizations must adopt tools that provide deep insights into both the container and host layers, enforce security policies, and ensure compliance in these dynamic and scalable environments.

With Qualys Solutions for Microsoft Azure Linux in AKS and Azure Container Instances, Qualys introduces a comprehensive solution for scanning Microsoft Azure Linux instances directly using the Qualys Cloud Agent. This new capability empowers organizations to manage and mitigate risks at both the host OS and container levels effectively. In this article, we delve into the distinct security challenges associated with Azure Linux in Azure Kubernetes Service (AKS) and Azure Container Instances and explore how Qualys, through its full-stack security approach, provides unparalleled visibility, actionable intelligence, and security auditing to safeguard containerized applications in the cloud.

Security Challenges

Securing containerized applications in Azure environments, such as Azure Kubernetes Service (AKS) and Azure Container Instances, is complex. Traditional security measures often fall short due to the unique nature of containers and their underlying host operating systems. Key challenges include:

• Lack of Asset Visibility: Comprehensive inventory management is essential to secure assets, including Azure Linux instances, which require detailed information about installed packages, open ports, users, and hardware.
• No Actionable Intelligence: Azure provides security advisories, but transforming this information into actionable intelligence for remediation without the right tools is challenging.
• Need for Security Auditing: Regulatory compliance demands stringent inventory management, patch verification, and security coverage, which is difficult without automated and repeatable processes.

How Qualys Solves These Challenges
