AIM: Supporting the reliability and resilience of critical networks

By Dieter Studer / R&M USA 

As critical networks become more complex, and cyber, physical, technological, and geopolitical risks increase, IT professionals face increasing security and uptime challenges, coupled with pressure to improve efficiency and performance. However, you can't manage – let alone optimize – anything you don't fully understand.

Critical networks cannot afford failures, delays, or security breaches, making them vastly different from regular networks. They are subject to stringent availability, security, and compliance requirements. They are designed for 24/7/365 operation with near-zero downtime. They incorporate redundant systems, failover mechanisms, and disaster recovery solutions to ensure high fault tolerance and uninterrupted service even during failures. 

Real-time operations, such as military command centers, power grid controls, and 911 emergency services, require ultra-low latency and high-speed data transmission. They often rely on dedicated fiber optic links and high-bandwidth infrastructures to achieve this. These networks face heightened security risks, including cyberattacks, espionage, and physical sabotage, requiring multi-layered protection through encryption, firewalls, intrusion detection, and air-gapped segments. 

Strict standards

Fiber networks must comply with strict industry standards and federal regulations. 

American National Standards Institute (ANSI), Cybersecurity and Infrastructure Security Agency (CISA), National Institute of Standards (NIST) and the Telecommunications Industry Association (TIA) have developed a series of key standards for the fiber industry to follow, including: 

·       TIA-606-B mandates infrastructure administration, emphasizing automated documentation for labeling and records.

·       ANSI/TIA-5017 addresses physical security, with AIM enabling continuous monitoring.

·       ANSI/TIA-5048 specifies AIM system requirements, ensuring interoperability and efficient network integration.

·       NIST SP 800-53 outlines security controls for federal systems, safeguarding data transmission across fiber networks.

·       CISA Guidelines focus on securing critical infrastructure, risk mitigation, coordinated responses, and intelligence sharing.

Playing it safe

Mapping physical infrastructure and knowing the position and status of every device and connection is critical for effective management and improving essential networks. Given the unique demands, Automated Infrastructure Management (AIM) solutions play a crucial role in critical networks. According to the TIA standard, AIM is an “integrated hardware and software system that automatically detects cable connections and disconnections, documents the cabling infrastructure, and enables efficient management and data exchange with other systems.”

AIM is often confused with DCIM (Data Center Infrastructure Management). However, while DCIM broadly refers to a wide range of DC management solutions—typically covering general physical infrastructure, power, or cooling—AIM specifically focuses on accurately documenting the physical network, including cabling and connectivity. AIM is a specialized system for tracking and managing physical network changes, including switches, servers, and patch panels. It provides real-time data on cabling infrastructure, asset management, changes, and alarms, enhancing operational efficiency and passive infrastructure management. AIM automates cable detection, documenting connections and equipment for accurate mapping, analysis, and planning.

Implementing AIM systems in critical networks offers many significant advantages. AIM provides real-time visibility into physical and logical network connections. Monitoring and documenting the physical layer reduces issues and downtime by quickly identifying and addressing connectivity issues.​ By maintaining accurate, up-to-date records of network connections, AIM helps prevent unauthorized access and modifications, detecting unauthorized access and changes to network infrastructure. Automated documentation and management streamline network operations, allowing for efficient resource allocation and maintenance processes. Furthermore, ongoing compliance with the most recent versions of all relevant regulatory frameworks is easily ensured. 

Making a smart choice

When choosing an AIM solution, a few things must be considered. AIM solutions must comply with relevant industry and federal standards. The AIM system should continuously monitor the entire fiber network and all ports in real time, ensuring accurate asset tracking through automated documentation to minimize human error. It should also provide instant alerts for connectivity issues, unauthorized access, and security breaches. 

The solution should feature multi-layered security, including encryption, authentication, and access control, while integrating with IDS and SIEM platforms for threat detection. It must provide detailed audit trails for compliance and forensic investigations. Designed for future growth, it should support high-density fiber, SDN, and AI-driven automation, ensuring scalability and compatibility with 5G, IoT, and edge computing.

Other essential requirements include perfect integration between hardware and software, advanced analytics for predictive maintenance and trend analysis, customizable reports for regulatory compliance, performance monitoring, capacity planning, and an intuitive user interface and centralized management dashboard. Obtaining DC hardware, cabling, and an AIM system, including software and dashboards, is ideal, as security and compatibility are "designed in" from the outset. 

The resilience of critical networks in the U.S. is more important than ever due to cyber threats, geopolitical tensions, infrastructure vulnerabilities, and technological shifts, which are increasing quickly in size and scope. A good AIM solution improves mission-critical networks' reliability, security, and IT process optimization.
