MQTT across boundaries: lightweight telemetry without trading away directionality

MQTT data diode: practical guidance for secure one-way data flow architectures.

Summary: MQTT powers smart infrastructure everywhere—from factory sensors to building automation—thanks to compact publish/subscribe semantics. Crossing security domains still demands architectural sobriety.

Broker adjacency risks

MQTT brokers often become concentration points. ConnexONE describes broker-capable roles that collect publisher traffic and relay toward sanctioned downstream brokers—without pretending MQTT magically enforces trust.

Near-real-time with guardrails

The guide summarises how Guardian and Postman cooperate to keep topic flows coherent while preserving the diode promise.

Maritime operations have entered a new era where data is mission-critical to safety, efficiency, compliance, and competitiveness.

Ships are now highly connected platforms, continuously exchanging telemetry with shore for voyage optimization, condition-based maintenance, emissions reporting, and security monitoring.

This transformation creates undeniable value, but it also expands the attack surface and elevates operational risk in environments where a single compromise can endanger life, cargo, vessels, and the marine environment.

Data diodes are critical for ISO 27001 compliance, providing unidirectional data flow to prevent unauthorized access and data exfiltration.

ISO/IEC 27001 is a globally recognized standard for managing information security, aimed at helping organizations protect their information assets such as financial data, intellectual property, and personal information.

It specifies requirements for establishing, implementing, maintaining, and continuously improving an Information Security Management System (ISMS), emphasizing risk management and continual improvement.

Key components of ISO 27001 include a systematic approach to managing sensitive information, identifying and treating risks, and implementing specific security controls. The standard is used across various industries to ensure compliance with legal and regulatory requirements, enhance customer trust, and provide a competitive advantage. It also supports operational efficiency, business continuity, and third-party assurance.

Data diodes are critical for ISO 27001 compliance, providing unidirectional data flow to prevent unauthorized access and data exfiltration. By enforcing strict network segmentation, data diodes isolate sensitive information, ensuring robust access control and secure communication channels. This hardware-enforced security mechanism protects against sophisticated cyber threats and ensures the integrity and confidentiality of critical data.
