Device Security Solution

To enhance our Device Security, Moxa has identified a big set of cybersecurity features based on the component requirements of IEC 62443. The set of security features have been implemented in a wide portfolio of devices, including Secure Routers, Rackmount Switches, EDS-500E series DIN Rail Switches, select models of Device Sever, and Protocol Gateways.

Prevent Intrusions and Attacks

To prevent network intrusions and attacks, it is essential to have a good access control mechanism in place that can identify, authenticate, and authorize users. Moxa’s network devices support user account management, password policy, and authentication interface management features that meet the technical security requirements of the IEC 62443 standard.

  • Operators can use these features to create user accounts and roles, grant different access privileges, and manage access to devices across networks
  • Authentication with IEEE 802.1x, RADIUS, TACACS+ and MAB(MAC Address bypass) helps devices that do not support IEEE 802.1x for easy management.
  • Port security with Static Lock helps to block hackers and careless usage. MAC address sticky can auto learn the device MAC without manual typing. ACL(Assess Control List) Provide network security by controlling access to devices.
  • Provide DoS Defense Capability by disable unencrypted and unused interfaces (e.g. HTTP, Telnet) and Limits the maximum login users to prevent device overload with superfluous requests

Prevent Intrusions and Attacks

Moxa’s devices support advanced HTTPS/SSH features, which provide a secure channel for data transfer over unsecure networks ensuring reliable processing and retrieval of data. To protect data from being stolen or corrupted, Moxa provides functions such as SNMP password encryption and network configuration encryption, which ensure the highest level of protection for your network devices.

The NPort 6000 secure servers use SSL to implement secure data transmission for Secure TCP Server, Secure TCP Client, Secure Pair Connection, and Secure Real COM modes.. The NPort’s drivers follow the SSL standard and automatically negotiate the encryption key. To prevent hacker attacks, the NPort will automatically switch from DES/3DES to AES encryption for highly secure data transmissions.

Track Network Events

Your cybersecurity journey does not end when your network security solution is up and running. You must constantly monitor your networks and audit network events for potential threats. Although it is quite difficult to detect breaches in real time, security event logs can help you identify the source of the issue. Information from these data logs can be used to track network activities, analyze potential threats, or identify devices that are incorrectly configured, which you can then use to disconnect user access, delete user accounts, or restart devices.

Moxa’s Solution Highlight

Security Management Solution

As ICS networks keep expanding and more networks continue to converge, it is important to understand the benefits of the defense-in-depth approach when designing security architecture. However, having cybersecurity building blocks deployed in an ICS network is not sufficient to completely protect critical assets from unauthorized access. According to a report published by ICS-CERT, a sound security management model should include the following stages:

  • Identify and secure network connections in the ICS
  • Harden network devices
  • Manage the human factor
  • Continually monitor and assess the network’s security status
  • Respond to incidents and get networks back to normal operation quickly

Those with malicious intent can still access the secure network if individuals who use the ICS network do not adhere to the security management model. In order to guarantee that the network has not been compromised, check if the ICS network is following the management principles and ensure that all users have read the guidelines to ensure a more secure ICS network.

Quick Questions to Ensure Best Practices are being Followed

Secure Access and Identity Management are Important

To prevent unauthorized access to your data and assets, it is essential to have secure access and identity management even for users who are accessing the ICS network from separate sites. It is very important to ensure that only authorized users are the ones accessing the network.

Device Management is Important.

No single product, solution, or approach can completely secure an ICS network. Therefore, it is very important to have an understanding of all the network devices and focus efforts on assets that, if disrupted, could have the greatest impact to the organization. Users should start by compiling a network topology to identify which ports can be connected to the network and which should be locked. In addition, the IP access table should be clear to all OT operators in order to prevent users who have not been granted access from connecting to the network.

Moxa’s Offering

Moxa offers many Ethernet switches that can be used with sticky MAC addresses in order to significantly enhance security.

Configuration Management

Based on the technical recommendations of the IEC 62443 standard, all event logs should be recorded. By having complete event logs, OT operators can trace any cybersecurity incident that occurs on the network and respond to the event in a timely manner. Moreover, network device configuration data should be kept confidential. If the configurations are changed without permission from the network operator, it could result in all of the data being corrupted. Therefore, configuration encryption and regular backups are very important to ensure that the network can return to normal quickly if a cybersecurity incident occurs.

Customer: Oil & Gas Service Company


High-capacity oil and gas pipelines are very volatile and often span thousands of kilometers. The pump stations along the pipeline are equipped with analyzers and PLCs. The company found it challenging to maintain a secure and stable network connection between the stations and the remote SCADA system because the PLCs and I/O devices did not have any security features.

Customer: Automotive Parts Plant


An automotive parts plant manager planned to digitalize their production processes. The field devices run on the EtherNet/IP protocol for control unification and data acquisition. As the network infrastructure in this plant is on a large scale, it is very difficult for the plant manager to monitor all devices and visualize the network topologies. In addition, to realize digitization, all networks are interconnected from the field site all the way to the ERP and even to the cloud. It is essential to have good cybersecurity measures to allow this transformation to occur, without compromising production efficiency.

Customer: CNC Machine Builder


Maximizing network uptime enhances machine productivity. Therefore, a leading manufacturer of mechanical power presses needed to provide a timelier and more efficient after-sales service in order to ensure improved machine performance and effective troubleshooting.
