Securing the Industrial Internet of Things (IIoT) in Built Environments
The Industrial Internet of Things (IIoT) has revolutionized how industries manage automation, optimize resources, and make real-time decisions. Whether in HVAC systems, logistics, maritime operations, or automated warehousing, IIoT enables seamless machine-to-machine (M2M) communication by connecting equipment to the internet. However, with this advancement comes increased cybersecurity risks, as every connected device becomes a potential attack vector.
Understanding IIoT in Built Environments
According to ASHRAE, the primary function of IIoT in the built environment is to enable field devices to pass collected data through edge nodes and relay devices to cloud services. These cloud-based systems then process and analyze data to support advanced decision-making, predictive maintenance, and operational efficiencies.
Industries leverage IIoT to:
✔ Prevent hardware failure through real-time diagnostics
✔ Optimize utility usage and purchasing
✔ Enhance resource management
✔ Automate processes for efficiency
However, without proper cybersecurity controls, IIoT-connected environments face growing threats that could compromise data integrity, operational uptime, and even physical security.
Common IIoT Cybersecurity Threats
IIoT cyberattacks most frequently target the communications interface of a device—the very pathway through which data is transmitted. By exploiting vulnerabilities in these pathways, attackers can intercept, manipulate, or disrupt critical operations.
Key attack surfaces in IIoT environments include:
🔹 Default Credentials & Poor Login Configurations – Weak authentication leaves devices exposed, allowing unauthorized access.
🔹 Unsecured Data Transmission – Lack of encryption at critical communication points can result in data leaks or interception.
🔹 Outdated Firmware & Software – Many legacy systems lack the flexibility to support modern security protocols, making them easy targets.
🔹 Hardware Disruptions – Attackers may physically manipulate or disable devices to bypass security controls.
Ignoring these vulnerabilities can cripple essential infrastructure, whether in building automation, power grids, or security systems.
Strengthening IIoT Security with Oasis
Oasis is a security platform designed to protect non-human identities (NHIs) in IIoT systems, offering a lifecycle management solution for connected devices. It provides:
🔹 Comprehensive Inventory Management – Identifies all machine identities, including device types, permissions, and ownership.
🔹 Risk Assessment & Remediation – Detects and classifies security risks while recommending corrective actions.
🔹 Access Control & Monitoring – Ensures that only authorized stakeholders interact with critical IIoT assets.
Key Security Best Practices for IIoT
Securing IIoT in built environments requires a multi-layered approach that addresses both human and technological vulnerabilities. Consider the following:
✔ Implement Strong Authentication Controls – Enforce multi-factor authentication (MFA) and eliminate default login credentials.
✔ Encrypt Data Transmission – Utilize encryption/decryption algorithms to protect sensitive data from interception.
✔ Deploy Standalone Security Appliances – If legacy systems cannot support security updates, standalone firewall appliances can help safeguard network entry points.
✔ Monitor & Segment Network Traffic – Isolate IIoT devices from critical IT systems to prevent unauthorized lateral movement.
✔ Ensure Proper Power & System Controls – Use uninterruptible power sources (UPS) and proper start/shutdown sequences to maintain firewall integrity.
The Future of IIoT Security
As automation and smart technologies continue to evolve, the demand for secure IIoT infrastructure will only grow. Organizations that fail to prioritize cybersecurity risk compromising their entire operational ecosystem. Whether through hardware upgrades, software patches, or enhanced network security, protecting IIoT systems should be a top priority for any industry leveraging connected devices.
