Enhanced NetScaler security against recurring network threats

October 23, 2025

Contributed by:

NetScaler provides enhanced protection against misbehaving and non-compliant network clients. This feature allows administrators to set a threshold for the maximum number of violations from a particular client. Once this threshold is exceeded, further requests from the offending client are blocked, providing improved security for services behind NetScaler. This enhancement is enabled through a new configuration parameter badIpActionThreshold in the NetProfile, and can be activated as needed.

Configure the Threshold setting by using the CLI

Add a new net profile and specify the badIpActionThreshold.

add netprofile <netprofile_name> -badIpActionThreshold <threshold_value>
<!--NeedCopy-->

Example:

add netprofile netprofile_1 -badIpActionThreshold 20
<!--NeedCopy-->

Bind the newly created net profile to a virtual server.

set lb vserver <vserver_name> -netprofile <netprofile_name>
<!--NeedCopy-->

Example:

set lb vserver h2lb -netprofile netprofile_1
<!--NeedCopy-->
