RTIR VERSION

Works with RTIR 5.0

INSTALLATION

May need root permissions

Patch RTIR for versions prior to 5.0.2

    patch -p1 -d /opt/rt5/local/plugins/RT-IR < patches/Add-callbacks-to-the-feed-listing-and-display-pages.patch

Edit your /opt/rt4/etc/RT_SiteConfig.pm

Add this line:

    Plugin('RTIR::Extension::MISP');

CONFIGURATION

Base MISP Configuration

Set the following in your RT_SiteConfig.pm with details for the MISP instance you want RTIR to integrate with.

    Set(%ExternalFeeds,
        'MISP' => [
            {   Name        => 'MISP',
                URI         => 'https://mymisp.example.com',  # Change to your MISP
                Description => 'My MISP Feed',
                DaysToFetch => 5,  # For the feed page, how many days back to fetch
                ApiKeyAuth  => 'API SECRET KEY',  # Change to your real key
            },
        ],
    );

MISP Custom Fields

If you want to display the MISP ID custom fields in a separate portlet on the incident page, you can customize your custom field portlets with something like this:

    Set(%CustomFieldGroupings,
        'RTIR::Ticket' => [
            'Networking'     => ['IP', 'Domain'],
            'Details' => ['How Reported','Reporter Type','Customer',
                          'Description', 'Resolution', 'Function', 'Classification',
                          'Customer',
                          'Netmask','Port','Where Blocked'],
            'MISP IDs'     => ['MISP Event ID', 'MISP Event UUID'],  # Add/remove CFs as needed
        ],
    );

DETAILS

This integration adds several different ways to work between the MISP and RTIR systems as described below.

Consume Feed from MISP

After adding the MISP configuration described above, the Feeds page in RTIR at RTIR > Tools > External Feeds will have a new MISP option listed. This feed pulls in events for the past X number of days based on the DaysToFetch configuration. From the feed display page, you can click the "Create new ticket" button to create a ticket with information from the MISP event.

MISP Portlet on Incident Display

On the Incident Display page, if the custom field MISP Event ID has a value, a portlet MISP Event Details will be displayed, showing details pulled in from the event via the MISP REST API.

Update MISP Event

On an incident with a MISP Event ID, the Actions menu will have an option "Update MISP Event". If you select this action, RTIR will update the existing MISP event with an RTIR object, including data from the incident ticket.

Create MISP Event

If MISP Event ID has no value, the Actions menu on incidents shows an option to "Create MISP Event". Select this to create an event in MISP with details from the incident ticket.
