While trying to define some custom attack-groups for IPS, I was unable to actually locate a full list of categories to define my groups with. As such, I've included a list for everyone from the latest Attack Database below:
root@SRX210_A% cli show security idp predefined-attacks | sed 's/\"//g' | awk -F":" '{print $1}' | uniq

As an aside, I found it mildly interesting to see the protections-per-category breakdown from Juniper:
