Seventy-nine percent of organizations also had OT networks with more than a pair of non-enterprise-grade remote access tools, which usually lack role-based access controls, auditing, multi-factor authentication, and session recording capabilities, as well as timely security fixes, a report from Claroty showed. Aside from raised security concerns, excessive remote access tools in OT environments have also brought about operational issues, including increased costs, reduced monitoring and detection efficiency, and inferior threat response efforts, noted Claroty researchers.
