This Alert Is From MOXA

As Industrial IoT (IIoT) adoption continues to proliferate, cybersecurity has become one of the top priorities. The Moxa Product Security Incident Response Team (PSIRT) takes a proactive approach to protect products from cybersecurity vulnerabilities. Moxa PSIRT investigates all reports of vulnerabilities that could potentially affect Moxa products. Moxa created a vulnerability management policy to provide guidance and information to our customers in the event of a reported vulnerability. The management policy ensures that Moxa’s customers have steady, unambiguous resources to help them understand how Moxa resolves or mitigates reported vulnerabilities. For any queries, please email [email protected].

Multiple product vulnerabilities were identified in Moxa’s NPort IAW5000A-I/O Series Wireless Device Server. In response to this, Moxa has developed related solutions to address these vulnerabilities.
