Configure Conditional Access Policy

python scripts/powershell_generator.py --action conditional-access --require-mfa --include-admins

Tools

powershell_generator.py

Generates ready-to-use PowerShell scripts for Microsoft 365 administration.

Usage:

# Generate security audit script
python scripts/powershell_generator.py --action audit

# Generate Conditional Access policy script
python scripts/powershell_generator.py --action conditional-access \
  --policy-name "Require MFA for Admins" \
  --require-mfa \
  --include-users "All"

# Generate bulk license assignment script
python scripts/powershell_generator.py --action license \

Output: Complete PowerShell scripts with error handling, logging, and best practices.

user_management.py

Automates user lifecycle operations and bulk provisioning.

Usage:

# Provision users from CSV
python scripts/user_management.py --action provision --csv new_users.csv

# Offboard user securely
python scripts/user_management.py --action offboard --user john.doe@company.com

# Generate inactive users report
python scripts/user_management.py --action report-inactive --days 90

# Generate DNS records configuration
python scripts/tenant_setup.py --action dns --domain acme.com

# Generate security baseline script
python scripts/tenant_setup.py --action security-baseline

Workflows

Workflow 1: New Tenant Setup

Step 1: Generate Setup Checklist

python scripts/tenant_setup.py --action checklist --company "Company Name" --users 100

Step 2: Configure DNS Records

python scripts/tenant_setup.py --action dns --domain company.com

Step 3: Apply Security Baseline

python scripts/powershell_generator.py --action audit > initial_audit.ps1

Step 4: Provision Users

python scripts/user_management.py --action provision --csv employees.csv --license E3

Workflow 2: Security Hardening

Step 1: Run Security Audit

python scripts/powershell_generator.py --action audit --output security_audit.ps1

Step 2: Create MFA Policy

python scripts/powershell_generator.py --action conditional-access \
  --policy-name "Require MFA All Users" \
  --require-mfa \
  --include-users "All"

Step 3: Review Results

Execute generated scripts and review CSV reports in output directory.

Workflow 3: User Offboarding

Step 1: Generate Offboarding Script

python scripts/user_management.py --action offboard --user departing.user@company.com

Step 2: Execute Script with -WhatIf

.\offboard_user.ps1 -WhatIf

Step 3: Execute for Real

.\offboard_user.ps1 -Confirm:$false

Best Practices

Tenant Setup

  1. Enable MFA before adding users
  2. Configure named locations for Conditional Access
  3. Use separate admin accounts with PIM
  4. Verify custom domains before bulk user creation
  5. Apply Microsoft Secure Score recommendations

Security Operations

  1. Start Conditional Access policies in report-only mode
  2. Use -WhatIf parameter before executing scripts
  3. Never hardcode credentials in scripts
  4. Enable audit logging for all operations
  5. Regular quarterly security reviews

PowerShell Automation

  1. Prefer Microsoft Graph over legacy MSOnline modules
  2. Include try/catch blocks for error handling
  3. Implement logging for audit trails
  4. Use Azure Key Vault for credential management
  5. Test in non-production tenant first
