+# Threat analytics for Spectre and Meltdown
+
+**Applies to:**
+
+- Windows 10 Enterprise
+- Windows 10 Education
+- Windows 10 Pro
+- Windows 10 Pro Education
+- Windows Defender Advanced Threat Protection (Windows Defender ATP)
+
+
+
+[Spectre and Meltdown](https://cloudblogs.microsoft.com/microsoftsecure/2018/01/09/understanding-the-performance-impact-of-spectre-and-meltdown-mitigations-on-windows-systems/) is a new class of exploits that take advantage of critical vulnerabilities in the CPU processors, allowing attackers running user-level, non-admin code to steal data from kernel memory. These exploits can potentially allow arbitrary non-admin code running on a host machine to harvest sensitive data belonging to other apps or system processes, including apps on guest VMs.
+
+Mitigating these vulnerabilities involves a complex multivendor update. It requires updates to Windows and Microsoft browsers using the [January 2018 Security Updates from Microsoft](https://portal.msrc.microsoft.com/en-us/security-guidance/releasenotedetail/858123b8-25ca-e711-a957-000d3a33cf99) and updates to processor microcode using fixes released by OEM and CPU vendors.
+
+## Prerequisites
+Note the following requirements and limitations of the charts and what you might be able to do to improve visibility of the mitigation status of machines in your network:
+
+- Only active machines running Windows 10 are checked for OS mitigations.
+- When checking for microcode mitgations, Windows Defender ATP currently checks for updates applicable to Intel CPU processors only.
+- To determine microcode mitigation status, machines must enable Windows Defender Antivirus and update to definition version 1.259.1545.0 or above.
+- To be covered under the overall mitigation status, machines must have both OS and microcode mitigation information.
+
+## Assess organizational risk with Threat analytics
+
+Threat analytics helps you continually assess and control risk exposure to Spectre and Meltdown. Use the charts to quickly identify machines for the presence or absence of the following mitigations:
+
+- **OS mitigation**: Identifies machines that have installed the January 2018 Security Updates from Microsoft and have not explicitly disabled any of the OS mitigations provided with these updates
+- **Microcode mitigation**: Identifies machines that have installed the necessary microcode updates or those that do not require them
+- **Overall mitigation status**: Identifies the completeness by which machines have mitigated against the Spectre and Meltdown exploits

+Click a section of each chart to get a list of the machines in the corresponding mitigation status.
