Choosing an Industrial Control Systems (ICS) Security Vendor
在 209 年第 4 季度的 Forrester Wave™：ICS Security Solutions, Q4 2021, Forrester analyzed ICS vendors’ current offering, strategy, and market presence based on 27 criteria, including:
ICS Protocols Support – understand, decode and parse protocols.*
Asset Discovery and Identification - continuously discover hardware and software attached or communicating to assets in a customer's operational technology network.*
Vulnerability Risk Management for OT - safely identify software, hardware, and configuration vulnerabilities in OT environments. Prioritize vulnerabilities for remediation.*
Threat Detection between Controllers and Field Devices – Threat detection by monitoring the signals between controllers (e.g., PLCs and safety systems) and field devices (e.g., actuators, pumps, burners, valves).*
Threat Detection between IT/OT Boundary & Controllers – Threat detection by monitoring the telemetry between the IT/OT DMZ and controllers (e.g., PLCs and safety systems).*
*Tenable’s definitions of Forrester’s evaluation criteria
Tenable leads by extending its ‘cyber exposure’ technologies across the IT/OT DMZ. Tenable acquired Indegy (now the Tenable.ot product) in late 2019 and has aggressively integrated it into its cyber exposure ecosystem including Nessus – one of the most used vulnerability scanners. Tenable’s strategy should benefit buyers from both the technology and budget side.Forrester Wave™：ICS Security Solutions Q4 2021, Forrester, November 2021
Tenable：Reduce Cyber Exposure and Secure Operations in a Rapidly Converging IT/OT World
Tenable received a leader status in The Forrester Wave™: ICS Security Solutions. Here's how we think our key capabilities can help you reduce cyber risk and secure your Operational Technology (OT) infrastructure:
Convergence Is Real
Whether planned or accidental, organizations are converging their IT/OT operations - and this can add new attack surfaces and vectors. Tenable.ot with Nessus built in desilos IT and OT operations by providing visibility, security and control across both.
Tenable is already known as a leader in the vulnerability assessment and vulnerability management space. With the inventory management and deep situational awareness gained, Tenable.ot is able to target the vulnerabilities relevant to each unique operation, and we can further triage each vuln through VPR scoring. No other OT vendor has the domain expertise in this area.
Know When Changes Occur
Changes to PLC programming can be completely normal, but it can also be an indication of a security incident. Tenable.ot provides snapshotting capabilities that enables tracking of these changes, and supports a “roll-back” if required.
