UBOS Asset Marketplace: Unleashing the Power of MCP Servers for Microsoft Sentinel

In the ever-evolving landscape of cybersecurity, proactive threat detection and rapid response are paramount. Organizations face an increasing barrage of sophisticated attacks, demanding robust security information and event management (SIEM) solutions. Microsoft Sentinel, a cloud-native SIEM platform, empowers security teams to analyze vast amounts of data, identify threats, and automate responses. However, the effectiveness of Sentinel hinges on the quality and efficiency of its underlying queries.

This is where UBOS Asset Marketplace’s MCP (Model Context Protocol) Servers come into play, specifically focusing on KQL (Kusto Query Language) queries designed for Microsoft Sentinel. UBOS, a full-stack AI Agent development platform, recognizes the critical role of data context in enhancing the capabilities of Large Language Models (LLMs) and AI agents. MCP serves as a standardized protocol that bridges the gap between applications and LLMs, allowing AI models to access and interact with external data sources. By leveraging MCP Servers within the UBOS ecosystem, security teams can significantly improve their threat hunting, incident response, and overall security posture.

What are MCP Servers?

At its core, an MCP Server is a collection of KQL queries tailored for specific security use cases within Microsoft Sentinel. KQL is the powerful query language used across Azure Monitor, Azure Data Explorer, and Azure Log Analytics, forming the foundation of data analysis within Sentinel. These pre-built queries are designed to efficiently extract valuable insights from the massive datasets ingested by Sentinel, enabling security analysts to identify threats, detect anomalies, and uncover hidden patterns.

Why are MCP Servers Important for Microsoft Sentinel?

• Accelerated Threat Detection: Manually crafting KQL queries can be a time-consuming and complex process, requiring in-depth knowledge of KQL syntax, data schemas, and security best practices. MCP Servers provide ready-to-use queries that are optimized for performance and accuracy, enabling security teams to quickly identify potential threats without spending hours writing and testing queries.
• Improved Detection Accuracy: The KQL queries within MCP Servers are meticulously crafted by security experts, incorporating industry-leading threat intelligence and detection techniques. This ensures that security teams are alerted to the most relevant and critical threats, minimizing false positives and improving overall detection accuracy.
• Enhanced Efficiency: By automating the query creation process, MCP Servers free up security analysts to focus on more strategic tasks, such as incident investigation, threat hunting, and security policy development. This increased efficiency allows security teams to respond to threats more quickly and effectively, reducing the potential impact of security incidents.
• Standardized Security Practices: MCP Servers promote a standardized approach to security monitoring and analysis by providing a consistent set of queries across the organization. This standardization ensures that all security analysts are using the same techniques and methodologies, improving collaboration and reducing the risk of overlooking critical threats.

This integration enables security teams to automate incident response, orchestrate security workflows, and build custom security solutions.

Use Cases for MCP Servers

• Proactive Threat Hunting: Security analysts can use the KQL queries within MCP Servers to proactively hunt for threats within their environment, identifying potential security incidents before they escalate.
• Incident Response: When a security incident occurs, security teams can use the MCP Servers to quickly investigate the incident, identify the root cause, and contain the damage.
• Security Monitoring: Security teams can use the MCP Servers to continuously monitor their environment for security threats, ensuring that they are alerted to any suspicious activity in real-time.
• Compliance Reporting: Security teams can use the MCP Servers to generate reports on their security posture, demonstrating compliance with industry regulations and security standards.

Examples of KQL Queries within MCP Servers

To illustrate the power and versatility of KQL queries within MCP Servers, let’s examine a few examples based on the provided information:

1. Detecting Successful Logons from Microsoft Teams:

kql SigninLogs | where TimeGenerated > ago(14d) | where UserPrincipalName == “reprise_99@testdomain.com” | where ResultType == “0” | where AppDisplayName == “Microsoft Teams” | project TimeGenerated, Location, IPAddress, UserAgent

This query identifies successful logons to Microsoft Teams by a specific user within the last 14 days. It then projects relevant information such as the timestamp, location, IP address, and user agent.

2. Finding Signin Logs within a Specific Time Range:

kql SigninLogs | where TimeGenerated between (ago(14d) … ago(7d))

This query retrieves all sign-in logs within a specific time range, from 14 days ago to 7 days ago.

3. Summarizing Signin Events by Application Display Name:

kql SigninLogs | where TimeGenerated > ago(14d) | where UserPrincipalName == “reprise_99@testdomain.com” | where ResultType == “0” | summarize count() by AppDisplayName

This query counts the number of sign-in events for a specific user, grouped by the application display name.

4. Visualizing Signin Count over Time:

kql SigninLogs | where TimeGenerated > ago(14d) | where UserPrincipalName == “reprise_99@testdomain.com” | where ResultType == “0” | summarize SigninCount=count() by bin(TimeGenerated, 1d) | render timechart

This query visualizes the number of sign-ins for a specific user over time, using a time chart to display the trend.

These are just a few examples of the many KQL queries that can be found within UBOS Asset Marketplace’s MCP Servers. By leveraging these queries, security teams can gain valuable insights into their environment and proactively protect against security threats.
