Remote access tools overused in OT environments, study indicates

TLDR:

The excessive use of remote access tools in operational technology (OT) environments can increase the attack surface, complicate identity management, and hinder visibility, according to a study by Claroty. Organizations using multiple remote access tools, including non-enterprise-grade solutions, are at risk of cybersecurity issues and operational inefficiencies. Lack of security features like multi-factor authentication and centralized controls can lead to vulnerabilities and misconfigurations.

Study Finds Excessive Use of Remote Access Tools in OT Environments

A study by cyber-physical systems security firm Claroty analyzed data from over 50,000 remote access-enabled devices in customers’ OT environments.

Key points from the study include:

• 55% of organizations use four or more remote access tools
• 79% have more than two non-enterprise-grade tools

Remote access tools like TeamViewer and AnyDesk have been targeted by threat actors, posing security risks.

In summary, the use of multiple remote access tools in OT environments can lead to increased attack surface, higher costs, monitoring inefficiencies, and deployment mistakes, emphasizing the need for enhanced security measures and centralized controls.
