What resources exist to research data on actual security incidents?
I would prefer an online resource but offline resources are acceptable. The cost of access should be less than $100 (US) for access to a statistically significant number of incidents. I would prefer databases that include more than just media reported security incidents.
I know of one online database RISI but a membership there is $995 (US) for 3 month access to their database. Are there similar databases at a lower cost?
