1. Introduction

We at Moxa understand that more and more of Moxa’s customers are concerned about the

security of their network system. Naturally, these concerns also extend to individual devices.

Moxa is committed to cybersecurity and endeavors to make our products as secure as

possible. In support of our customers to meet certain security guidelines and frameworks, this

document intends to provide guidelines on how to configure and secure the installation of

Moxa’s devices.

We want to reiterate that the recommended steps to securing a Moxa device, as discussed in

this document, are guidelines as applications vary from one Moxa customer to another.

Furthermore, these recommendations are best practices for most applications. However, to

ensure the recommended settings are applicable to your environment without creating a

conflict or affecting your application, it’s highly recommended to review and test the

configuration thoroughly before implementing it in your production system.
