About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Microsoft’s Email Encryption Behavior May Violate HIPAA, New Paubox Report Warns

New evidence shows Microsoft 365 may expose sensitive health information over email without encryption or notice—posing HIPAA compliance risks for providers

A new report from Paubox, a leader in HIPAA compliant email, reveals that Microsoft 365’s email encryption behavior could be putting healthcare organizations at serious risk of noncompliance.

In a series of controlled TLS experiments, Paubox researchers found that Microsoft 365 may transmit messages in cleartext when encryption fails, without bouncing the message, alerting the sender, or logging any evidence of the failure. This occurred when messages were sent to recipient servers that did not support modern TLS protocols.

The messages in question contained simulated PHI and were sent in accordance with typical “force TLS” configurations that many IT leaders believe are sufficient for HIPAA compliance.

“Our team expected the message to bounce,” said Hoala Greevy, CEO of Paubox. “Instead, it went through unencrypted—and unless you knew where to look in the headers, you’d have no idea.”

Microsoft’s fallback behavior directly contradicts the expectations outlined in HIPAA’s Security Rule (45 CFR §164.312(e)(1)), which requires technical safeguards to ensure PHI is protected in transit. If encryption fails, and there is no way to detect or prove it, healthcare organizations may be unknowingly transmitting PHI without the protections HIPAA requires.

According to the report:

  • Microsoft 365 will attempt TLS fallback—and if that fails, deliver in cleartext
  • No warning or notification is provided to the sender
  • Encryption failures are not recorded in any accessible audit trail
  • This behavior is the default, not a misconfiguration

Paubox also calls out broader issues with relying on force TLS settings in cloud platforms, calling the practice a “false sense of security that cannot be audited.”

Healthcare IT and compliance leaders are encouraged to review the findings and test their own environments.
