IOT/OT NETWORK SECURITY AUDIT
Scope and Components of the Audit
This type of audit focuses on evaluating each aspect of IoT and OT network security, including device configuration, access control, and security of communication protocols, in order to strengthen the security posture in an environment of connected devices and systems:
IoT Device Security Assessment
We review the configuration and management of connected IoT devices, evaluating aspects such as authentication, firmware updates, and data encryption practices, to prevent unauthorized access and protect sensitive information managed by these devices.
OT Network Configuration Analysis
OT networks include industrial control and automation systems, such as SCADA and PLCs. We conduct a deep analysis of their configuration to ensure they are isolated from lower-security networks, reviewing access policies and applying advanced security controls to minimize the risks of disruption or manipulation.
Communication Protocol and Encryption Review
We analyze the communication protocols used in IoT and OT networks, evaluating their resistance to interception and ensuring the use of robust encryption where applicable. This includes verifying that protocols such as MQTT, CoAP, Modbus, and others comply with security standards to prevent eavesdropping and manipulation of data in transit.
Network Segmentation and Isolation
We verify the segmentation and isolation of IoT and OT networks, ensuring they are adequately segregated from the general corporate network. This minimizes the risk of lateral movement in case a device is compromised, keeping critical systems protected from unauthorized access from external networks.
Vulnerability Management and Patching
We review the management of security updates and patches on IoT and OT devices, identifying those that may be outdated or unsupported and pose a risk. We also recommend update policies that help maintain the security of these critical devices over time.
Audit Objectives
The objective of the IoT/OT Network Audit is to provide a comprehensive review that allows the organization to strengthen the security of its IoT and OT networks and devices. By contracting this service, companies achieve proactive protection of their critical systems, minimizing the risks of disruption, unauthorized access, and cyber attacks in connected environments that depend on operational control and stability.
