Garland Technology 2021 Buyer’s Guide Vendor for Industrial Cybersecurity

May 26, 2021

New York — May 26, 2021 — Garland Technology, a leading provider of network TAP, packet broker, and cloud visibility solutions, is pleased to announce it has been included in the 2021 OT/ICS Tech Buyers Guide for Industrial Cybersecurity Technology and Solutions from Takepoint Research and IndustrialCyber.

Jonathon Gordon, Directing Analyst at Takepoint Research, addressing the market maturity from OT/ICS Cyber to Industrial Cybersecurity, “We see the focus shifting. Instead of addressing vulnerabilities in isolation, companies are thinking strategically about how to identify, quantify, and prioritize the gamut of cyber risks they face, so they can implement the right solutions to secure the industrial enterprise from end-to-end.”

This edition of the Industrial Cybersecurity Solutions Buyers Guide is designed to steer you through the technology weeds, and get you to the cyber solutions that can meet industrial enterprise needs. The guide provides clear and concise explanations about the many cyber solutions available to protect your industrial enterprise from internal and external threats.

Takepoint Research along with many others now refer to this market as ‘Industrial Cyber’ rather than OT/ICS Cyber, representing a fundamental shift in how the vendors, service providers, consultants and industrial enterprises who comprise this market, view the cybersecurity challenge.

One size does not fit all. This search shows a a more diverse range of technologies and many more specialized solutions for industrial enterprises. Cyber awareness is growing and vendors are adapting.

The categorization framework in this guide is designed to enable Industrial Enterprises to identify, evaluate and determine what type of technology and solution may be beneficial to their organization, and cover:

  • Cyber-Physical Security and Operational Systems Health
  • Deception and Honeypots
  • Identity and Access Management (IAM)
  • Industrial IoT (IIoT) Device Security
  • IT/OT Endpoint Security and Patch Management
  • Network Discovery, Monitoring and Threat Detection
  • Perimeter Security and Network Segmentation
  • Product and Supply Chain Security
  • Risk Management, Governance and Compliance
  • Secure Remote Access and Zero Trust
  • Social Engineering and Phishing Security

Heartbeats Packets Inside the Bypass TAP

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.

If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.

While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.

Some of you may have noticed a flaw in the logic behind this solution!  You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.

Glossary

  1. Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.

  2. Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.

  3. Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
