Azure DevOps Security Alert Agent

A comprehensive Python-based tool designed to collect, analyze, and manage Advanced Security alerts from Azure DevOps repositories. This agent provides security teams with centralized visibility into their organization's security posture across multiple repositories and projects.

Project Overview

Modern software development organizations often have hundreds of repositories across multiple Azure DevOps projects, making it challenging to maintain visibility into security alerts and vulnerabilities. The Azure DevOps Security Alert Agent solves this problem by automatically collecting security alerts from across your entire Azure DevOps organization and providing powerful analysis and reporting capabilities.

The tool leverages Azure DevOps Advanced Security features to gather alert data, stores it in a structured format, and enables comprehensive analysis to help security teams prioritize remediation efforts and track security trends over time.

Core Features

Alert Collection and Management

Comprehensive Alert Retrieval

# Example: Collecting alerts from multiple repositories
from src.client.azure_devops_client import AzureDevOpsClient
from src.models.alert import Alert

client = AzureDevOpsClient(config)

# Collect alerts from all repositories in an organization
for project in client.get_projects():
    for repository in client.get_repositories(project.id):
        alerts = client.get_security_alerts(project.id, repository.id)
        
        for alert_data in alerts:
            alert = Alert.from_api_response(alert_data)
            storage.save_alert(alert)
            
print(f"Collected {len(alerts)} security alerts")

Rich Metadata Extraction

• Alert severity levels (Critical, High, Medium, Low)
• Alert states (Active, Dismissed, Fixed)
• Vulnerability types (Code Quality, Secret Scanning, Dependency Vulnerabilities)
• Repository and project context
• Timeline and historical data
• Remediation status tracking

Advanced Analysis Engine

Multi-dimensional Filtering and Grouping

# Example: Advanced alert analysis
from src.analysis.query import AlertAnalyzer

analyzer = AlertAnalyzer(database_connection)

# Filter alerts by multiple criteria
critical_alerts = analyzer.filter_alerts(
    severity=['Critical', 'High'],
    state='Active',
    repository_pattern='*-production-*',
    date_range=(start_date, end_date)
)

# Group alerts by various dimensions
severity_breakdown = analyzer.group_by_severity()
repository_distribution = analyzer.group_by_repository()
trend_analysis = analyzer.analyze_trends(period='monthly')

# Generate comprehensive reports
report = analyzer.generate_executive_summary()

Trend Analysis and Reporting

• Historical trend analysis with configurable time periods
• Alert velocity tracking (new alerts vs. resolved alerts)
• Security posture improvement metrics
• Repository-level security scoring
• Executive dashboard data generation

Flexible Authentication

Multiple Authentication Methods

# config/config.yaml - Personal Access Token
authentication:
  method: "pat"
  personal_access_token: "${AZURE_DEVOPS_PAT}"

  method: "oauth"
  client_id: "${AZURE_CLIENT_ID}"
  client_secret: "${AZURE_CLIENT_SECRET}"
  tenant_id: "${AZURE_TENANT_ID}"
  organization: "your-organization"

Secure Credential Management
