DevOps Security |
Enforce security of workload throughout DevOps lifecycle |
Shared |
**Security Principle:**
Ensure the workload is secured throughout the entire lifecycle in development, testing, and deployment stage. Use Azure Security Benchmark to evaluate the controls (such as network security, identity management, privileged access and so on) that can be set as guardrails by default or shift left prior to the deployment stage. In particular, ensure the following controls are in place in your DevOps process:
- Automate the deployment by using Azure or third-party tooling in the CI/CD workflow, infrastructure management (infrastructure as code), and testing to reduce human error and attack surface.
- Ensure VMs, container images and other artifacts are secure from malicious manipulation.
- Scan the workload artifacts (in other words, container images, dependencies, SAST and DAST scans) prior to the deployment in the CI/CD workflow
- Deploy vulnerability assessment and threat detection capability into the production environment and continuously use these capabilities in the run-time.
**Azure Guidance:**
Guidance for Azure VMs:
- Use Azure Shared Image Gallery to share and control access to your images by different users, service principals, or AD groups within your organization. Use Azure role-based access control (Azure RBAC) to ensure that only authorized users can access your custom images.
- Define the secure configuration baselines for the VMs to eliminate unnecessary credentials, permissions, and packages. Through custom images, Azure Resource Manager template, and/or Azure Policy guest configuration to deploy and enforce these the configuration baseline.
Guidance for Azure container services:
- Use Azure Container Registry (ACR) to create your private container registry where a granular access can be restricted through Azure RBAC, so only authorized services and accounts can access the containers in the private registry.
- Use Defender for Azure Container Registry for vulnerability assessment of the images in your private Azure Container Registry. In addition, you can use Microsoft Defender for Cloud to ingrate container images scan as part of your CI/CD workflows.
For Azure serverless services, adopt the similar controls to ensure security controls are shift left to the stage prior to the deployment.

Posture and Vulnerability Management |
Rapidly and automatically remediate vulnerabilities |
Shared |
**Security Principle:**
Rapidly and automatically deploy patches and updates to remediate vulnerabilities in your cloud resources. Use the appropriate risk-based approach to prioritize the remediation of the vulnerabilities. For example, more severe vulnerabilities in a higher value asset should be addressed as a higher priority.
**Azure Guidance:**
Use Azure Automation Update Management or a third-party solution to ensure that the most recent security updates are installed on your Windows and Linux VMs. For Windows VMs, ensure Windows Update has been enabled and set to update automatically.
For third-party software, use a third-party patch management solution or System Center Updates Publisher for Configuration Manager.
Prioritize which updates to deploy first using a common risk scoring program (such as Common Vulnerability Scoring System) or the default risk ratings provided by your third-party scanning tool and tailor to your environment. You should also consider which applications present a high security risk and which ones require high uptime.
