SEL Software-Defined Networking (SDN) With Flow Auditor

Streamline audits and strengthen defenses with a new cybersecurity solution.

Collecting data for NERC CIP audits typically requires days of network scanning to document open ports and services—a process that can impact network performance and interfere with critical systems. But now, you can avoid those scans altogether.

Purpose-built for operational technology (OT) environments, SEL SDN is a solution that simplifies and strengthens cybersecurity. With the new Flow Auditor application, SDN allows you to collect data for NERC CIP reporting in just minutes, rather than days.

Streamlined Data Collection

With SDN, all network flows and backup paths are preconfigured in the controller. This means that much of the information you need for NERC CIP reporting—the active devices, ports, and services on your network—is already available without conducting any network scans.

Flow Auditor allows you to gather this information quickly and easily. It compiles data directly from the controller database, rather than querying every device—thereby eliminating the risk of disrupting network performance.

Cybersecure Architecture

Because SDN has predefined network flows, it doesn’t rely on traditional features like MAC tables or the Rapid Spanning Tree Protocol (RSTP). By removing those features, SDN eliminates numerous cybersecurity vulnerabilities, such as MAC flooding and table poisoning.

SDN also strengthens cybersecurity by employing a deny-by-default architecture—in which communications are only forwarded if they match a strict set of predefined rules. This provides an additional layer of defenses that prevents malware or other unauthorized traffic from traveling within the substation LAN.

 

Flexible Mounting Options

To support a greater range of applications, SDN is now offered with two different Ethernet switches—the new DIN-rail- or surface-mounted SEL-2742S switch and the rack-mounted SEL-2740S switch. Both switches are designed with durable materials to withstand harsh environments and extreme temperatures.
