Configuration Change Detected (Low)
The system detected a change in the controller code that was made via the network. An attacker may use code changes to disrupt normal operations, to cause production losses, or to create a security threat. This plugin only works with Tenable.ot. Please visit...
Abnormal Asset Behavior Detected (Low)
This asset behavior is an anomaly that needs to be verified for the root cause. This plugin only works with Tenable.ot. Please visit https://www.tenable.com/products/tenable-ot for more information. %NASLMINLEVEL 80900 C Tenable, Inc. include'compat.inc'; if description scriptid503202;...
Device Status Modification Detected (High)
Changes in the controller state can stop operations altogether or start an operation that should not have been started. These operations can be used by an attacker to disrupt normal operation, cause production losses, or create safety concerns. This plugin only works with Tenable.ot. Please visit...
Threat Exposure Indicators Detected (High)
Intrusion detection events may indicate that the network has been compromised and is exposed to malicious entities. It is important to be aware of any such traffic that may indicate reconnaissance activity, attacks on the network, or propagation of a threat to/from other subnets of the network...
Device Presence Anomaly Detected (Critical)
It is important to know what assets exist in your network. New assets can indicate unexpected network connections, third-party connectivity, or potential threats to the network. This plugin only works with Tenable.ot. Please visit https://www.tenable.com/products/tenable-ot for more information...

Controller Code Upload Detected (Critical)
An upload of the controller code has been detected over the network. When not part of regular operations, a code upload can be used to gather information about the controller behavior as part of reconnaissance activity. This plugin only works with Tenable.ot. Please visit...
Unsecured Authentication Attempt Detected (Medium)
A server allow for authentication using credentials in an unencrypted manner over unencrypted channel. Such credentials might be revealed to an attacker intercepting this traffic and used to gain access to data on the server. This plugin only works with Tenable.ot. Please visit...
