Microsoft is set to launch the Vulnerability Remediation Agent in May 2025 (public preview), integrating Defender Vulnerability Management with Microsoft Intune for streamlined vulnerability mitigation. This agent automates vulnerability assessments, prioritizes CVEs based on CVSS scores, and offers AI-driven impact analysis.
Key Features:
- Automated Scheduling: Runs scans based on Intune-configured schedules.
- CVE Prioritization: Displays total CVEs evaluated, remediation targets, and severity scores.
- AI-Powered Insights: Provides exploitability analysis, affected systems, and exposure levels.
- Remediation Tasks: Suggests OS updates, app patches, and policy fixes.
🔗 Reference: Microsoft Vulnerability Remediation Agent
You Should Know:
1. Verify Vulnerabilities with Linux/Windows Commands
- Linux (CVEs in installed packages):
apt list --upgradable # Debian/Ubuntu yum list updates # RHEL/CentOS rpm -qa --last | head -10 # Recently updated packages
- Windows (Check missing patches):
Get-HotFix | Sort-Object InstalledOn -Descending | Select -First 10 wmic qfe list full /format:table
2. Simulate Remediation (Linux/Windows)
- Linux (Kernel Update):
sudo apt update && sudo apt upgrade -y # Debian/Ubuntu sudo dnf upgrade --security # Fedora/RHEL
- Windows (Force Update):
Install-Module PSWindowsUpdate -Force Install-WindowsUpdate -AcceptAll -AutoReboot
3. Validate Patch Compliance
- NMAP (Post-Remediation Scan):
nmap -sV --script vuln <target_IP>
- Microsoft Defender (Post-Scan):
Start-MpScan -ScanType FullScan
4. Log Analysis for Exploit Attempts
- Linux (Auth Logs):
grep "FAILED LOGIN" /var/log/auth.log journalctl --since "1 hour ago" | grep "vulnerability"
- Windows (Event Logs):
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}
What Undercode Say:
Microsoft’s Vulnerability Remediation Agent bridges Defender VM and Intune, but manual validation remains critical. Use Linux/Windows commands to cross-check patches, enforce hardening (e.g., chmod 600 /etc/shadow), and monitor logs. AI-driven prioritization accelerates response, but NMAP, Wazuh, or OpenSCAP ensure no gaps. Always:
sudo lynis audit system # Linux hardening audit
For Windows, enforce **LAPS** and **Credential Guard**:
Enable-WindowsOptionalFeature -Online -FeatureName "Windows-Defender-CredentialGuard"
## **Expected Output:**
- Linux: List of pending security updates.
- Windows: Installed patches + reboot status.
- NMAP: Open ports with CVE-linked services.
- Defender: Post-remediation scan report.
