These gateway devices often contain both known and zero-day vulnerabilities that remain unpatched due to poor visibility and neglected maintenance in OT environments. The widespread deployment of these devices creates an attractive attack surface for threat actors seeking to compromise critical infrastructure. Organizations must treat these network bridge devices as critical security assets requiring active vulnerability management and regular security updates.","**Immediate actions:**\n- Conduct comprehensive inventory of all serial-to-IP converters and network bridge devices\n- Apply latest firmware updates and security patches to identified devices\n- Implement network segmentation to isolate OT networks from corporate IT systems\n\n**Long-term improvements:**\n- Establish regular vulnerability scanning schedules for all OT gateway devices\n- Deploy network monitoring tools to detect unauthorized access to industrial systems\n- Create standardized security baseline configurations for all network interface devices\n\n**Governance measures:**\n- Develop vendor security assessment procedures for OT device procurement\n- Implement change management processes for OT network infrastructure modifications",[12,13,14,15,16,17],"CIS Control 7","CIS Control 12","NIST SP 800-82","IEC 62443-3-3","NIST CSF PR.IP-1","NIST CSF DE.CM-7","published","2026-04-20T20:09:42.803042+00:00","2026-04-20T20:09:42.729+00:00",{"id":7,"url":22,"slug":23,"title":24},"https:\u002F\u002Fwww.darkreading.com\u002Fics-ot-security\u002Fserial-ip-devices-thousands-of-bugs","serial-to-ip-devices-hide-thousands-of-old-and-new-bugs-319252","Serial-to-IP Devices Hide Thousands of Old and New Bugs",[26,32],{"id":27,"name":28,"slug":29,"description":30,"color":31},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":33,"name":34,"slug":35,"description":36,"color":37},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[]]
