Secure Remote Access with BlastShield

OT Secure Remote Access is Paramount for OT Networks

Secure remote access is a cornerstone of modern critical infrastructure operations, enabling OT administrators to connect to their networks and resources from any location. However, secure remote access has become an Achilles heel for OT networks for the following reasons:

  1. MFA is Critical: Credentials Theft is behind 90% of successful cyber attacks.

CISA’s 2022 Year in Review reported that over 90% of successful cyber attacks start with a phishing email and promoted multifactor authentication as one of their four key steps to keep companies cyber-safe. The introduction of AI-based Phishing tools has made phishing a more insidious threat to credential theft. Users often reuse passwords across multiple platforms, increasing the risk of a security breach. Simple username and password combinations lack the robustness to secure sensitive data and resources and do not offer the same level of security as multi-factor authentication (MFA) methods, specifically biometric authentication.

  1. VPNs Increasingly Challenged in OT Environments: Scalability, Complexity, and Vulnerability.

Traditional Virtual Private Networks (VPNs) are no longer sufficient to deliver the Secure Remote Access OT networks need. There is a growing need for more robust security measures that can adapt to the changing threat landscape and provide a secure yet user-friendly remote access experience. VPNs often struggle with scalability, especially when many remote users simultaneously access the network. VPNs require significant management overhead, including server infrastructure maintenance and client software configuration. Even more troubling is that VPNs are increasingly prone to sophisticated cyber attacks and zero-day vulnerabilities. Once breached, an improperly configured VPN client can provide attackers with access to the entire network.

  1. Regulatory Requirements Growing: Protect the Keys to the Kingdom

Multiple OT industry regulatory bodies have added Secure Remote Access as a critical component of cybersecurity compliance. The NIST Cybersecurity Framework, NERC CIP, and ISA/IEC 62443 all promote secure remote access and Zero Trust Network Access (ZTNA) to enforce least privilege access to OT networks BEFORE granting access to resources.
