Use this skill when asked to trace authentication flows, analyze SessionId chains, investigate token reuse vs interactive MFA, or assess geographic anomalies in sign-ins. Triggers on keywords like "trace authentication", "trace back to interactive MFA", "SessionId analysis", "token reuse", "geographic anomaly", "impossible travel", or when investigating suspicious sign-in locations. This skill provides forensic analysis of Entra ID authentication chains to distinguish legitimate activity from credential/token theft.
Use this skill when asked to investigate Conditional Access policy changes, sign-in failures related to CA policies (error codes 53000, 50074, 530032), or suspected policy bypass/manipulation. Triggers on keywords like "Conditional Access", "CA policy", "device compliance", "policy bypass", "53000", "50074", or when investigating why a user was blocked then suddenly unblocked. This skill provides forensic analysis of CA policy modifications correlated with sign-in failures.
Use this skill when asked to investigate a computer, device, endpoint, or machine for security issues, suspicious activity, malware, or compliance review. Triggers on keywords like "investigate computer", "investigate device", "investigate endpoint", "check machine", "device security", "endpoint investigation", or when a device name/hostname is mentioned with investigation context. This skill provides comprehensive device security analysis including Defender alerts, sign-in patterns, logged-on users, vulnerabilities, software inventory, compliance status, network activity, and automated investigation tracking for Entra Joined, Hybrid Joined, and Entra Registered devices.
Create, deploy, update, and manage custom detection rules in Microsoft Defender XDR via the Graph API (/beta/security/rules/detectionRules). Covers query adaptation from Sentinel KQL to custom detection format, deployment via PowerShell (Invoke-MgGraphRequest), manifest-driven batch deployment, and lifecycle management (list, enable/disable, delete). Companion script: Deploy-CustomDetections.ps1.
Use this skill when asked to generate a vulnerability and exposure management report, assess security posture, or review CVEs, security configurations, and attack paths. Triggers on keywords like "vulnerability report", "exposure report", "CVE assessment", "security posture", "vulnerability assessment", "exposure management", "patch status", "end of support", "security recommendations", "attack paths", "critical assets", "configuration compliance", "Defender device health", "security score", "TVM", "threat and vulnerability management", or when asking about overall organizational vulnerability/exposure state. This skill queries DeviceTvm* tables and ExposureGraphNodes/Edges to produce a comprehensive posture report covering CVEs, exploitable vulnerabilities, security configuration compliance, end-of-support software, critical asset inventory, attack paths, Defender device health, and certificate status. Supports org-wide and per-device scoping with inline chat and markdown file output.
Use this skill when asked to analyze, investigate, or report on honeypot server security. Triggers on keywords like "honeypot investigation", "analyze honeypot", "honeypot security", "honeypot report", or when a server name is mentioned with honeypot analysis context. This skill provides comprehensive security analysis including attack patterns, threat intelligence correlation, IP enrichment, vulnerability assessment, and executive report generation.
Use this skill when asked to investigate a security incident by ID from Microsoft Defender XDR or Microsoft Sentinel. Triggers on keywords like "investigate incident", "incident ID", "incident investigation", "analyze incident", "triage incident", or when an incident number/ID is mentioned with investigation context. This skill provides comprehensive incident analysis including metadata retrieval, alert listing, asset enumeration, evidence filtering, and deep entity investigation using Sentinel MCP tools and specialized skills.
Use this skill when asked to investigate an Indicator of Compromise (IoC) such as an IP address, DNS domain, URL, or file hash. Triggers on keywords like "investigate IP", "check domain", "IoC investigation", "threat intel", "is this malicious", "suspicious URL", or when an IP/domain/URL/hash is mentioned with investigation context. This skill provides comprehensive IoC analysis using Microsoft Defender Threat Intelligence, Sentinel Threat Intel tables, Advanced Hunting, organizational exposure assessment, CVE correlation, and affected device enumeration.
