Security Infrastructure

This document outlines the security infrastructure for the AI Agent Orchestration Platform.

Overview

The platform implements a comprehensive security infrastructure to protect data, services, and users. This document covers authentication, authorization, encryption, network security, monitoring, and compliance aspects of the security infrastructure.

Security Architecture

The security architecture follows a defense-in-depth approach with multiple layers of protection:

1. Perimeter Security: Firewalls, WAF, DDoS protection
2. Network Security: Segmentation, encryption, access controls
3. Application Security: Authentication, authorization, input validation
4. Data Security: Encryption, access controls, data governance
5. Monitoring & Detection: Logging, monitoring, intrusion detection
6. Response & Recovery: Incident response, backup, disaster recovery

Note: This is a placeholder for a security architecture diagram. The actual diagram should be created and added to the project.

Authentication Infrastructure

Identity Management

The platform uses a robust identity management system:

• User Directory: Store user identities and attributes
• Multi-Factor Authentication: Require multiple factors for authentication
• Single Sign-On: Integrate with enterprise identity providers
• Password Policies: Enforce strong password requirements
• Account Lifecycle: Manage user provisioning and deprovisioning

Example identity management configuration:

# identity-management.yaml
identity_providers:
  - type: internal
    enabled: true
    password_policy:
      min_length: 12
      require_uppercase: true
      require_lowercase: true
      require_numbers: true
      require_special_chars: true
      max_age_days: 90
      history_count: 10

  - type: oauth2
    enabled: true
    providers:
      - name: google
        client_id: ${GOOGLE_CLIENT_ID}
        client_secret: ${GOOGLE_CLIENT_SECRET}
        scopes: [email, profile]

      - name: github
        client_id: ${GITHUB_CLIENT_ID}
        client_secret: ${GITHUB_CLIENT_SECRET}
        scopes: [user:email]

  echo "Usage: ./rotate_keys.sh [key_type] [key_path]"
  echo "Example: ./rotate_keys.sh jwt /etc/meta-agent/keys/jwt"
  exit 1

echo "Rotating $KEY_TYPE keys at $KEY_PATH..."

# Generate new keys
case $KEY_TYPE in
  jwt)
    openssl genrsa -out $KEY_PATH-new.key 4096
    openssl rsa -in $KEY_PATH-new.key -pubout -out $KEY_PATH-new.pub
    ;;

  aes)
    openssl rand -base64 32 > $KEY_PATH-new.key
    ;;

  *)
    echo "Unknown key type: $KEY_TYPE"
    exit 1
    ;;
esac

# Backup old keys
cp $KEY_PATH.key $KEY_PATH.key.bak
cp $KEY_PATH.pub $KEY_PATH.pub.bak 2>/dev/null || true

# Deploy new keys
mv $KEY_PATH-new.key $KEY_PATH.key
mv $KEY_PATH-new.pub $KEY_PATH.pub 2>/dev/null || true

# Update key references
./update_key_references.sh $KEY_TYPE

echo "Key rotation complete for $KEY_TYPE"
