Deploying the AcuSensor agent for JAVA - Windows

πŸ” AcuSensor Network PreRequisites

AcuSensor makes use of the AcuSensor Bridge. Read more information here.

Acunetix JAVA Acusensor requires Tomcat (7+) and Java (1.7+). Current testing is with Tomcat 9 and Java 1.8.

The AcuSensor agent will need to be deployed to your web application. This section describes how to deploy AcuSensor to a JAVA web application.

The Java AcuSensor requires:

  • Deploying aspectjweaver.jar into your web server - provides the integration required for AcuSensor to work with your application
  • Deploying the Acunetix Java AcuSensor into your web server - this is unique for each Target, and can be downloaded by using the Download JAVA AcuSensor button
  • Configuring your web server to use Load Time Weaving (AspectJWeaver)

Assumptions for this document

Note: This document assumes that you will be using version 1.9.5 (latest at time of writing) of AspectJWeaver.

Deploying AspectJWeaver into your web application

Deploying AcuSensor into your web server

  • Download the Acunetix JAVA AcuSensor from the Acunetix UI

AcuSensor for a specific web application on the web server (Recommended)

  • Copy the Acunetix JAVA AcuSensor (AcuSensor.jar) to %TOMCAT-HOME%\webapps\<your_app_folder>\WEB-INF\lib
  • If installing on Windows where Tomcat 9 was installed using the official "32-bit/64-bit Windows Service Installer", copy the AcuSensor.jar file to C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\webapps\<your_app_folder>\WEB-INF\lib or C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\<your_app_folder>\WEB-INF\lib

AcuSensor for all web applications on the web server

  • Copy the Acunetix JAVA AcuSensor (AcuSensor.jar) to %TOMCAT-HOME%\lib
  • If installing on Windows where Tomcat 9 was installed using the official "32-bit/64-bit Windows Service Installer", copy the AcuSensor.jar file to C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\lib or C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib
  • You will need to adjust your AcuSensor password to use a single AcuSensor for the entire web server - more information here.
  • Note that deploying AcuSensor for all web applications on the web server can have a performance hit

Configure Tomcat to use AspectJWeaver and AcuSensor

  • Launch Tomcat with Load Time Weaving enabled. This can be done by adding a -javaagentΒ parameter with the path to aspectjweaver.jar when launching Tomcat, and optionally a parameter to enable AcuSensor debug logging
  • Add 2 parameters into the Apache Tomcat Configuration > JAVA options tab
  1. -javaagent:C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\lib\aspectjweaver.jar (mandatory; adjust path depending on where you deployed the aspectjweaver.jar file)
  2. -Dacusensor.debug.log=ON (optional; enables debug logging)

  • restart the Tomcat service

Note: The parameter "-Dacusensor.debug.log=ON" is optional, and can be omitted. If this parameter is retained, this will output AcuSensor logging as additional lines in the Tomcat logs starting with "[Acunetix-debug]".

Disabling and Removing AcuSensor for JAVA

To remove and disable the sensor from your website you need to revert the changes done during the deployment of the Agent.:

  • Remove the Acunetix JAVA AcuSensor (AcuSensor.jar) from the folder or folders where it was deployed
  • Remove aspectjweaver.jar from the folder where it was copied to
  • Reconfigure Tomcat with Load Time Weaving disabled, as follows:
  1. remove the -javaagentΒ and -Dacusensor.debug.logΒ parameters in the Apache Tomcat Configuration > JAVA options tab
  2. restart the Tomcat service

Note: Although the Acunetix AcuSensor agent is secured with a strong password, it is recommended that the AcuSensor client files are uninstalled and removed from the web application if they are no longer in use.
