Accura implements OT IDS (Intrusion Detection System) in critical infrastructure by deploying advanced sensors and monitoring technologies in SCADA ICS / DCS that detect anomalies and potential threats in real time.

Why it is necessary to have visibility in the OT network

• You cannot protect what you cannot see. Accura offers and implements industrial cyber security solutions such as network threat detection (Intrusion Detection System) and other cyber technologies for threat detection.
• Without an IDS, an attacker can be resident in an OT network for up to 160 days on average and achieve incredible freedom and lateral movement allowing significant disruption of production processes when you least expect it.
• Good detection enables better response, and better response enables even better prevention against cyber threats that can have devastating effects on control systems.

Required features for OT IDS

• Comprehensive asset visibility: IDS must provide a clear overview of your industrial assets so you know what to protect and where your critical assets are located. With good asset visibility, operators not only get a clearer picture of what's running in their OT environment, but are able to make more informed decisions about how to secure it .
• Threat detection: IDS monitors operational activity and network traffic in real-time, looking for patterns that indicate potential attacks or anomalies (e.g., unusual behavior, unusual data transfers, unusual commands). It uses specialized rules and profiles for ICS/SCADA systems that are different from rules for IT networks.
• Deep packet inspection: OT IDS monitors industrial protocols such as Modbus, DNP3, OPC-UA, IEC 104, CIP, BACnet and dozens of others that are commonly found in control systems. It analyzes these logs to detect vulnerabilities or unauthorized tampering attempts.
• Vulnerability management: the IDS solution includes a vulnerability management module, where the platform provides the information necessary to focus on vulnerabilities (based on known vulnerabilities (CVE - Common Vulnerabilities and Exposures)) with the highest priority, to mitigate identified risks and threats, minimize downtime and have allocated cybersecurity resources where they are most needed. IDS will provide information on how to fix vulnerabilities through vendor-provided patches..
• Incident Response: When OT IDS detects an anomaly or attack, it generates alerts for security teams and provides detailed information about the incident, including IP addresses, time stamps, and attack type. Integration with SIEM systems (Security Information and Event Management) enables fast data correlation and automated response to incidents.
• Forensic analysis: IDS contains detailed information about threats and anomalies, which will help defenders to effectively start the process of responding to cyber incidents, and from the collected forensic data, it will help to investigate incidents.
• Compliance with standards and regulations: OT IDS can help organizations meet the security requirements of standards such as the Cyber Security Act, NERC CIP, IEC 62443 or NIST SP 800-82, which are relevant to industrial environments. Monitoring and recording operations ensures auditability and supports compliance processes:
