  • Unified security management is also one of the unique features of the solutions which are achieved after the integration with Microsoft Sentinel that provides the user with a comprehensive view of the whole organization.

Agentless monitoring and Network-layer security: An understanding

Agentless Security

The agentless monitoring technique is also known as passive monitoring provides the necessary agentless security system required by user organizations in contemporary times. This technique provides a safe and complete inventory of all the IoT/OT assets with zero impact on IoT/OT performance. The user companies can also analyze diverse and proprietary industrial protocols to visualize the IoT/OT network topology and see the other communication pathways.

This information can later be used to accelerate network segmentation and zero trust initiatives. The feature is specifically advantageous for manufacturers as it gives equipment details such as manufacturer, device type, serial number, firmware level, and backplane layouts. Quick identification of the root causes of operational issues such as misconfigured devices and networks is also possible.

Benefits of integrating Azure Defender for IoT:

The Azure Defender for IoT can be integrated with the Microsoft Sentinel which turns out to be quite beneficial for the user organizations. This feature provides the user with a sharp view across all the IT/OT boundaries with Interoperability that is provided within IoT/OT – specific SOAR playbooks. These playbooks can help in automating responses.

Along with this, the machine learning and threat intelligence capacities from trillions of signals collected across the global ecosystem of Microsoft can be augmented by IoT/OT-specific intelligence collection research team. The user organizations can also prevent attacks through extended detection and response from Microsoft 365 Defender. Finally, the user is also provided with Interoperability with other SOC tools like Splunk, IBM QRadar, and ServiceNow.

Behavioral analytics: Meaning and its implications

Zero Trust Approach in Azure for IoT

Behavioral analytics is one of the unique features of the Azure Defender for IoT. This allows the user organization to monitor internal activities like anomalous or unauthorized activity using IoT/IoT aware behavioral analytics and threat intelligence capabilities. The Zero Trust Security can be strengthened by instantaneously detecting unauthorized remote access and unauthorized or compromised devices.

In addition to this, the real-time alerts can be rapidly tracked through historical network traffic analysis. Also, modern-day threats like zero-day malware and living off-the-land tactics can be identified.

Benefits of using Azure Defender IoT for new initiatives:

The benefits of using Azure Defender IoT for new IoT initiatives can be reaped by the manufacturers and solution operators. These facilities can be categorized in the following manner:-

Built-in IoT/OT security capabilities

For new IoT projects – The Azure IoT security strategy involves the capacity to help protect new IoT devices and other Azure IoT projects from the first day through the deployment of the Defender for IoT security micro-agents. This reduces risks with real-time security passive monitoring across standard IoT operating systems. In addition to this, the feature also supports compliance and continuous visibility into the user organization’s IoT security, directly from the endpoint. The continuous threat intelligence of Microsoft can detect the evolution of threats. Also, custom alerts can be created for defining the most critical threats to the environment of the user organization.

Protecting IoT devices with minimal impact on the endpoint

This feature allows the user organization to deploy endpoint security with minimal impact on the IoT devices. It is possible because the Defender for IoT security micro-agent has a small footprint and consists of no OS kernel dependencies. In addition to this, the user organizations can deploy using the distribution model that is designed to work best for their devices along with modifying source code to further customize the agent that is required for the specific needs. Micro-agents are made available for the standard IoT operating systems, including Linux and Azure RTOS.

Securing the Azure IoT projects from edge to cloud
