Azure_Security_Benchmark_v3.0 PV-6 Azure_Security_Benchmark_v3.0_PV-6 Microsoft cloud security benchmark PV-6 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. **Implementation and additional context:** How to configure Update Management for virtual machines in Azure: https://docs.microsoft.com/azure/automation/update-management/overview Manage updates and patches for your Azure VMs: https://docs.microsoft.com/azure/automation/update-management/manage-updates-for-vm n/a link 7
CIS_Azure_2.0.0 2.1.13 CIS_Azure_2.0.0_2.1.13 CIS Microsoft Azure Foundations Benchmark recommendation 2.1.13 2.1 Ensure that Microsoft Defender Recommendation for 'Apply system updates' status is 'Completed' Shared Running Microsoft Defender for Cloud incurs additional charges for each resource monitored. Please see attached reference for exact charges per hour. Ensure that the latest OS patches for all virtual machines are applied. Windows and Linux virtual machines should be kept updated to: - Address a specific bug or flaw - Improve an OS or application’s general stability - Fix a security vulnerability The Azure Security Center retrieves a list of available security and critical updates from Windows Update or Windows Server Update Services (WSUS), depending on which service is configured on a Windows VM. The security center also checks for the latest updates in Linux systems. If a VM is missing a system update, the security center will recommend system updates be applied. link 1
