A Comprehensive Guide to OT Network Security

OT networks are facing many cybersecurity challenges nowadays, especially when it comes to IIoT and Industry 4.0 when every device is connected to the internet. OT security threats cause damages to productivity, revenue, brand reputation, intellectual property, and physical safety.​ In modern OT environments, maintaining safety and reliability of legacy systems, lack of asset visibility across network infrastructure, and imperative to control access to your networks and devices are the most common and the most critical threats. With Moxa, you can rely on compliance with the IEC 62443 standard to secure your control systems. We identify three tips to easily defend your network security.

Achieving Network Security for Industrial Automation

In order to optimize operational efficiency for modern industrial automation systems, network convergence between OT and IT is imperative. While streamlining your OT/IT networks unlocks the potential of your industrial systems, it also raises network security concerns. It is a particular concern for those OT systems that used to be air gapped but must still protect network communications without interrupting operations. As a leader in industrial networking for over 30 years, Moxa is committed to developing secure and reliable networking solutions that proactively identify and mitigate cyberthreats in OT environments. To realize this commitment, Moxa strictly follows secure-by-design practices, utilizes distributed OT intrusion prevention systems capabilities, and provides a wide array of rugged networking portfolios to perfect defending industrial applications in depth.

Why Industrial Network Security Matters

Increasing Connected Devices
According to a survey by IDC, around 40% of the respondents will invest in automation to digitalize their industrial operations.*
Rising Ransomware Cyberattacks
Ransomware has been exploited by malicious parties to conduct untargeted attacks for financial gain.
Targeting Critical Infrastructure
In addition to financial gain, critical infrastructure is being targeted to trigger public panic and threaten national security.
