This feature enables the execution of different custom actions over ticket attachments. These actions could come from modules such as the
ScanWithVirusTotal module or from web services that administrators can define in order to send attachment information to a third party system for analysis, process, count, etc.
In order to send the attachment information to a third party server it might be needed to be extracted or transformed from the OTRS format to a format that the other system can understand. Also the response from the other system needs to be converted to a special format in order to be processed and recorded by the attachment actions. This data format change or transformation can be done by using the mapping modules in OTRS generic interface, especially the XSLT mapping module should be capable to accomplish this task.
Setup VirusTotal Module¶
The system already comes with a module to send attachments to be checked by Virus Total via upload of the attachment. The attachment action associated to this module is not enabled by default.
To activate the virus scan module:
- Go to the VirusTotal website and create an account.
- Find and copy the API key provided by VirusTotal to use their web services.
- Add the API key to the
- Enable the VirusTotal attachment action in the Attachment Action Management screen (see below).
More module based attachment actions might be added later to STORM.
Create Web Services¶
Attachment actions can also use web services instead of predefined modules. This let the administrator to integrate their actions with remote servers as needed using XSLT mappings to transform data outbound and inbound.
Attachment actions should use the invoker
Ticket::AttachmentAction as it prevents to send other attachments in the request and it also knows how to handle the results. This invoker comes with STORM.
After the inbound mapping the invoker should provide the key
<AttachmentActionResult> with the following sub keys:
A number from 1 to 6. The list of status codes and proposed usage are the following:
1(Alert): Currently not in use (color purple).
2(Critical): Used for internal server errors (color purple).
3(Error): Execution errors (color red).
4(Warning): Execution was correct but external errors reported (color orange).
5(Notice): Execution was correct but results are not present or represent minor issues (color yellow).
6(Info): Everything is fine (color green).
- A string to be displayed as a tool tip.
- Full result details in plain text format.
The web services can be created in the Web Services module of the administrator interface. The usage of this management screen is identical with the usage of the web service management screen of the OTRS framework.
Here is an example for XSLT mapping:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <xsl:copy> <RootElement> <AttachmentActionResult> <Status>5</Status> <Result>Web service sampple result</Result> <Details>This is an example</Details> </AttachmentActionResult>\r\n </RootElement> </xsl:copy> </xsl:template> </xsl:stylesheet>"
Manage Attachment Actions¶
After the web service was created by the administrator, it is necessary to create a new attachment action where the web service name has to be set and the invoker from the drop-down list has to be selected. There is a new module to manage the attachment actions. The attachment actions management screen is available in the Attachment Actions module of the Ticket Settings group in the administrator interface.
To add a web service as attachment action:
- Click on the Add Attachment Action button in the left sidebar.
- Fill in the required fields.
- Click on the Save button.
It is possible to create attachment actions for modules or web services. However, only one module
ScanWithVirusTotal is shipped with STORM, while new web services can be defined by the administrators.
Attachment actions can not be deleted from the system. They can only be deactivated by setting the Validity option to invalid or invalid-temporarily.
To edit an attachment action:
- Click on an attachment action in the list of attachment actions.
- Modify the fields.
- Click on the Save or Save and finish button.
The attachment actions can be used in any attachment widget of the detail views.
To use the attachment actions:
- Create a new ticket.
- Fill in the required fields.
- Add some attachments.
- Go to the ticket detail view and find the Attachments widget.
- Any attachment action has an own column in the Attachments widget.
The icons displayed in the widget is the same as set up for the action in the administrator interface. The color of the icons has been explained above.
A column will be added for each attachment action. Try to define as many attachment actions as really needed, otherwise the widget might not fit in small screens.
