Setting up classification & mapping for email ingest

ce13 — Sat, 06 Aug 2022 10:51:30 GMT

Hi,

Here are two different emails subject:

1. Test email - Phishing Email

2. Test email - Ping

Two playbooks:

1. Phishing Email

2. Ping

Currently I have setup two instances of integration "Mail Listener v2" with corresponding incident types so that phishing email will go to playbook - phishing email and ping email will go to playbook - ping.

I am looking for setting one instance of integration "Mail Listener v2" and using classification and mapping to send the alerts into different playbooks by keywords in subject. What I am trying to do is if the email subject contains "Phishing Email" and sender is from specific sender, then it will be sent to playbook - Phishing email", and similar actions for ping.

Does anyone know if this is possible or I have to keep using two instances for this setup? Thanks.

What you're trying to do is definitely possible with a single Mail Listener + classifier, but you may need to rethink your classification logic.

The classifier expects that a single field (+ filter + transformer set) will produce a (mostly) fixed list of values, and those values can be mapped onto incident types. This is simple and easy to do based solely on sender or receiver email addresses - each email address value goes to a different incident type. More complex logic (e.g. "it has X in the subject AND ...") may be possible, but you'd essentially need to fight to fit it within the classifier design, rather than it fitting neatly.

Also, since you only get a single mapper object per mail listener, if you are currently using two different mappers you'll need to combine the mappers you're currently using into a single mapper. Mappers can have incident-type-specific mappings so you won't lose any custom logic in this process but it will be a little bit of extra work.
