Block Legacy Authentication for Manufacturing & Industrial

How manufacturing & industrial organizations should implement ID-02 for Microsoft 365 security and compliance.

For manufacturing & industrial companies using Microsoft 365, block legacy authentication is a security priority. This guide explains how ID-02 helps manufacturing & industrial organizations protect their identity infrastructure while meeting industry-specific compliance mandates.

Why Manufacturing & Industrial Organizations Need This Control

Manufacturing & Industrial organizations face specific regulatory requirements including iso27001, nist-800-53, cis. The ID-02 control helps address these requirements by:

  • A Conditional Access policy blocks legacy authentication protocols (IMAP, POP3, SMTP, older Office clients)
  • No exceptions for legacy protocols except documented service accounts

Legacy protocols like IMAP and POP3 cannot enforce MFA. Attackers specifically target these protocols to bypass your MFA policies. Blocking them closes a major attack vector.

Industry-Specific Considerations

When implementing ID-02 in a manufacturing & industrial environment, consider:

  • **Regulatory requirements**: iso27001, nist-800-53, cis may mandate specific configurations
  • **Risk tolerance**: Manufacturing & Industrial 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

ID-02 requires the following configuration:

  • A Conditional Access policy blocks legacy authentication protocols (IMAP, POP3, SMTP, older Office clients)
  • No exceptions for legacy protocols except documented service accounts

Creates a Conditional Access policy blocking legacy authentication for all users

With TrueConfig, you can implement this control automatically using our one-click remediation feature.

Manufacturing Compliance Requirements

Manufacturing organizations must comply with these frameworks, all of which address block legacy authentication:

Why This Control Matters for Manufacturing

Legacy protocols like IMAP and POP3 cannot enforce MFA. Attackers specifically target these protocols to bypass your MFA policies. Blocking them closes a major attack vector.

Common threats in manufacturing & industrial:

  • • Ransomware targeting production systems
  • • IP theft through credential compromise
  • • Supply chain infiltration

For manufacturing & industrial organizations, ID-02 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
