Enhance your CI/CD deployment by using Vulnerability Assessments from Microsoft Defender for ACR
By embedding Microsoft Defender for container registries assessments into your CI/CD pipeline, you can address this need and have a more secure automation and deployment processes in enterprise environments. This blog will take you through a few simple steps to take your CI/CD pipeline to the next security level.AKS Security Dashboard
In today’s digital landscape, the speed of development and security must go hand in hand. Applications are being developed and deployed faster than ever before. Containerized application developers and platform teams enjoy the flexibility and scale that Kubernetes has brought to the software development world. Open-source code and tools have transformed the industry - but with speed comes increased risk and a growing attack surface. However, in vast parts of the software industry, developers and platform engineering teams find it challenging to prioritize security. They are required to deliver features quickly and security practices can sometimes be seen as obstacles that slow down the development process. Lack of knowledge or awareness of the latest security threats and best practices make it challenging to build secure applications. The new Azure Kubernetes Service (AKS) security dashboard aims to alleviate these pains by providing comprehensive visibility and automated remediation capabilities for security issues, empowering platform engineering teams to secure their Kubernetes environment more effectively and easily. Consolidating security and operational data in one place directly within the AKS portal allows engineers to benefit from a unified view of their Kubernetes environment. Enabling more efficient detection, and remediation of security issues, with minimal disruption to their workflows. Eventually reducing the risk of oversight security issues and improving remediation cycles. To leverage the AKS security dashboard, navigate to the Microsoft Defender for Cloud section in the AKS Azure portal. If your cluster is already onboarded to Defender for Containers or Defender CSPM, security recommendations will appear on the dashboard. If not, it may take up to 24 hours after onboarding before Defender for Cloud scans your cluster and delivers insights. Security issues identified in the cluster, surfaced in the dashboard are prioritized to risk. Risk level is dynamically calculated by an automatic attack path engine operating behind the scenes. This engine assesses the exploitability of security issues by considering multiple factors, such as cluster RBAC (Role Based Access Control), known exploitability in the wild, internet exposure, and more. Learn more about how Defender for Cloud calculates risk. Security issues surfaced in the dashboard are divided into different tabs: Runtime environment vulnerability assessment: The dynamic and complex nature of Kubernetes environments means that vulnerabilities can arise from multiple sources, with different ownership for the fix. For vulnerabilities originating from the containerized application code, Defender for Cloud will point out every vulnerable container running in the cluster. For each vulnerable container Defender for cloud will surface remediation guidelines that include the list of vulnerable software packages and specify the version that contains the fix. The scanning of container images powered by Microsoft Defender Vulnerability Management (MDVM) includes scanning of both OS packages and language specific packages see the full list of the supported OS and their versions. For vulnerabilities originating from the AKS infrastructure, Defender for cloud will include a list of all identified CVEs (common vulnerabilities and exposures) and recommend next steps for remediation. Remediation may include upgrading the Node pool image version or the AKS version itself. Since new vulnerabilities are discovered daily, even if a scanning tool is deployed as part of the CI/CD process, runtime scan can’t be overlooked. Defender for cloud makes sure Kubernetes workloads are scanned daily compared to an up-to-date vulnerability list. Security misconfigurations: Security misconfigurations are also highlighted in the AKS security dashboard, empowering developers and platform teams to execute fixes that can significantly minimize the attack surface. In some cases, changing a single line of code in a container's YAML file, without affecting application functionality, can eliminate a significant attack vector. Each security misconfiguration highlighted in the AKS security dashboard includes manual remediation steps, and where applicable, an automated fix button is also available. For containers misconfigurations, a quick link to a built-in Azure policy is included for easily preventing future faulty deployments of that kind. This approach empowers DevOps & platform engineering teams to use the “Secure by Default” method for application development. To conclude - automated remediation and prevention can be a game changer in keeping the cluster secure- a proactive approach that can help prevent security breaches before they can cause damage, ensuring that the cluster remains secure and compliant with industry standards. Ultimately, automated remediation empowers security teams to focus on more strategic tasks, knowing that their Kubernetes environment is continuously monitored and protected. Assigning owners to security issues Since cluster administration and containers security issues remediation is not always the responsibility of a single team or person, it is recommended to use the “assign owner” button in the security dashboard to notify the correct owner about the issue need to be handled. It is also possible to filter the view using the built-in filters and assign multiple issues to the same person quickly. Get Started Today To start leveraging these new features in Microsoft Defender for Cloud, ensure either Defender for Container or Defender CSPM is enabled in your cloud environments. For additional guidance or support, visit our deployment guide for a full subscription coverage, or enable on a single cluster using the dashboard settings section.
