DNP3 Security Risks
DNP3 Cybersecurity Risks DNP3 (Distributed Network Protocol version 3) is a widely used communications protocol for industrial control systems (ICS) and supervisory control and data acquisition (SCADA) systems. While DNP3 provides several features designed to enhance the reliability and efficiency of communication between control devices and data acquisition systems, it also poses certain security risks,…
Read MoreIncreasing Cyberattacks on Water Utilities
Water Utilities Cyberattacks Hacker groups from Russia, China, and Iran have all taken credit for recent cyberattacks on water utility companies in recent months, the EPA even warning smaller communities to take action. Water utility companies are on notice during federal inspections over the last year. Roughly 70% of them violated standards meant to prevent…
Read MoreIncreased Number of Cyber Exposed OT/ICS Devices
Exposed OT/ICS Devices Recent data from several tracking sources indicates there has been an increase in the number of public IP addresses with accessible devices using standard OT/ICS protocols – BACnet, Modbus, Fox, Ethernet/IP, S7, and more. Data from three different sources – Censys, ShadowServer, and Shodan – give insight into the number of publicly…
Read MoreBuilding Management System Cybersecurity Best Practices
A strong cybersecurity posture is essential for Building Management Systems to mitigate the risks associated with interconnected devices and systems. Building Management System Overview A Building Management System (BMS), also known as a Building Automation System (BAS) or Building Control System (BCS), is a computer-based control system that manages and monitors the mechanical, electrical, and…
Read MoreThe Role of Cybersecurity for IoT Devices
The Internet of Things (IoT) has revolutionized the way we live and work. With billions of connected devices, from smartphones to home appliances, building controls and industrial machinery, our world is more interconnected than ever before. However, this connectivity also brings with it significant security risks. Cybersecurity plays a crucial role in ensuring that data…
Read MoreMonetary Damage of Reported Cybercrime in the US from 2001-2022
Growth in Cybercrime Cybercrime is not just a threat to data and privacy; it also comes with a significant monetary cost. The monetary damage of reported cybercrime in the United States grew steadily from 2001-2017, and then accelerated starting in 2018. There was a year-over-year increase of around 50 percent from 2021 to 2022. Since…
Read MoreBACnet Security Issues and How to Mitigate Cyber Risks
BACnet is a commonly used protocol for building automation and operational technology (OT) systems, and is used to establish communication between various devices in a network. Because BACnet-based building systems were originally deployed in isolated (air-gapped) environments, BACnet was not designed with security. Therefore, millions of BACnet devices are lacking common security mechanisms such as…
Read MoreImproving BACnet Secure Connect (BACnet/SC) Deployment with Automated Certificate Management
Managing BACnet Secure Connect (BACnet/SC) certificates can be a challenging task, especially for large buildings. Just recently at the AHR Expo 2024, we learned of a project that had over 300 devices and the decision was made to use 10-year certificates due to the multiple days (3-4) of labor needed to deploy BACnet/SC certificates. The…
Read MoreBACnet MS/TP Security Risks and Vulnerabilities
What is BACnet MS/TP? BACnet MS/TP (Master-Slave/Token-Passing) is a widely used communication protocol in building automation and control systems. BACnet MS/TP is implemented with a shared bus and one or more building control devices daisy-chained along the wiring from a controller or a BACnet IP router/gateway. It is commonly used to connect field devices such…
Read MoreSmart Building Cybersecurity Best Practices
The true power of smart buildings lies in their ability to adapt and respond intelligently to the needs of occupants, enhancing comfort, efficiency, and sustainability. Understanding Smart Buildings Smart Buildings are structures equipped with a network of interconnected devices, sensors, and systems that collect and exchange data to optimize various aspects of building operations including…
