Require Phishing-Resistant MFA for Admins for Legal Services

How legal services organizations should implement PA-05 for Microsoft 365 security and compliance.

For legal services companies using Microsoft 365, require phishing-resistant mfa for admins is a security priority. This guide explains how PA-05 helps legal services organizations protect their identity infrastructure while meeting industry-specific compliance mandates.

Why Legal Services Organizations Need This Control

Legal Services organizations face specific regulatory requirements including soc2, iso27001, cis. The PA-05 control helps address these requirements by:

  • All users with privileged roles have registered phishing-resistant MFA
  • FIDO2 security keys, Windows Hello for Business, or device-bound passkeys required
  • SMS and voice call MFA methods are blocked for admin accounts

Traditional MFA (push notifications, SMS) can be bypassed through social engineering and MFA fatigue attacks. Phishing-resistant methods like FIDO2 keys cannot be phished because they require physical presence and cryptographic proof.

Industry-Specific Considerations

When implementing PA-05 in a legal services environment, consider:

  • **Regulatory requirements**: soc2, iso27001, cis may mandate specific configurations
  • **Risk tolerance**: Legal Services organizations typically have moderate to low risk tolerance
  • **Audit frequency**: Plan for regular compliance reviews
  • **Documentation**: Maintain detailed records for regulatory inspections

How to Configure

PA-05 requires the following configuration:

  • All users with privileged roles have registered phishing-resistant MFA
  • FIDO2 security keys, Windows Hello for Business, or device-bound passkeys required
