Secure Bypass

Remote access to industrial control systems is high risk: stolen passwords and two-factor devices introduce vulnerabilities to control systems. In addition, when a firewall is hacked, attackers gain direct access to critical systems, while third-party personnel threaten reliable operations when remote changes are made outside of a site’s change control procedures. The Waterfall Secure Bypass Module provides physical protection for emergency and other remote support mechanisms, and gives the industrial site physical control over enabling the frequency and duration of remote access.

Waterfall’s Secure Bypass Module is deployed in parallel with Unidirectional Security Gateways. While the module is not engaged, the Gateways provide 100% protection from external online attacks. When activated, the Secure Bypass Module enables time-limited bi-directional connectivity to a unidirectionally-protected network for plant emergencies and scheduled changes as well as vendor, IT, internal support and other remote access needs.
