![]() With this, customers can correlate events across OT and IIoT devices. You can use AWS Security Hub to provide a centralized view of all security-related findings, where you can set up alerting and automatic remediation.Ĭustomers using AWS IoT Device Defender to audit and monitor IIoT devices can import its findings into AWS Security Hub – learn how in this blog. Findings from each service are normalized into the AWS Security Finding Format (ASFF), so that you can review findings in a standardized format and take action quickly. Now with this solution to stream syslog data from OT IDS solutions, you can ingest security findings from your OT environment into AWS Security Hub. When combined with an OT IDS solution, you can get a centralized view of security events across OT and AWS, helping to improve your security posture across factory and cloud which is essential when implementing IIoT solutions.ĪWS Security Hub ingests findings from multiple AWS services, including Amazon GuardDuty, Amazon Inspector, Amazon Macie, AWS Firewall Manager, AWS Identity and Access Management (IAM) Access Analyzer, and AWS Systems Manager Patch Manager. To address this challenge, we are providing a custom solution to integrate security events from OT Intrusion Detection Solutions (IDS) like Dragos, Claroty and Nozomi into AWS Security Hub.ĪWS Security Hub provides a centralized view of your security posture in AWS and helps check your environment against security standards and current AWS security recommendations. This creates the need for a security monitoring solution across the attack surface and threat landscape. This poses problems since cyber events could originate in OT and move to IT, or vice versa. One of the many challenges in securing complex heterogeneous factory and cloud environments when implementing IIoT solutions is the lack of visibility into security events across factory and cloud. Deploying security monitoring and centrally managing alerts across OT, IIoT and cloud is one of the ten security golden rules for IIoT solutions. This provides visibility of security events to teams responsible for security monitoring of IIoT solutions without the costly and often time-consuming effort needed to integrate OT security solutions into existing Security Operations Center (SOC) solutions. In this blog, we describe a new approach to security monitoring across OT, IIoT and cloud by integrating OT security solutions with AWS. In order to realize the full benefits of IT/OT convergence and IIoT, IT and OT teams are better off if they join forces to mount the most effective defense and build trust. This can result in siloed OT, IIoT and cloud security monitoring solutions, creating blind spots bad actors could exploit. ![]() Traditionally, OT and IT/cloud teams have worked on separate sides of the air gap as laid out in the Purdue Model. As this SANS whitepaper recommends, organizations should establish strategies to prevent, detect, respond, and recover across the entire attack surface which includes Operational Technology (OT), edge and cloud, and on-site and off-site assets. Industrial organizations should be aware of the risks that come along with the benefits of this convergence and cloud adoption. While this new and expanding “physical meets digital” connectivity enables great rewards, it also introduces new risk, which needs to be properly managed. Continuous digitalization and progressive interconnectivity of the production environment is important to capturing value from industrial IoT (IIoT) solutions. Industrial digital transformation can increase competitiveness and optimize processes and profitability through the use of big data, IoT, machine-to-machine communication, and machine learning.
