VERIS Framework

Data

The DBIR is an ongoing study that analyzes forensic evidence to uncover how sensitive data is stolen from organizations, who’s doing it, why

they’re doing it, and what might be done to prevent it.

- 2013 DBIR -19 global contributors

47,000+ security incidents621 confirmed data breaches

Methodology: Data Collection and Analysis

• DBIR participants use the Vocabulary for Event Recording and Incident Sharing (VERIS) framework to collect and share data.

• Enables case data to be shared anonymously to RISK Team for analysis

VERIS is a (open and free) set of metrics designed to provide a common language for describing security incidents (or threats) in a structured and repeatable manner.

How VERIS worksINCIDENT REPORT“An external attacker sends a phishing email

that successfully lures an executive to open an attachment. Once executed, malware is installed on the exec’s laptop, creating a backdoor. The attacker then accesses the laptop via the backdoor, viewing email and other sensitive data. The attacker then finds and accesses a mapped file server that an internal admin failed to properly secure during the build/deployment process. This results in intellectual property being stolen from the server…”

A security INCIDENT is a series of EVENTS that adversely affect the information assets of an organization. Every event is comprised of the following ELEMENTS:

Discovery & Mitigation

• Incident timeline

• Discovery method

• Evidence sources

• Control capability

• Corrective action– Most straightforward manner in which the incident

could be prevented

– The cost of preventative controls

+

Impact Classification

• Impact categorization– Sources of Impact (direct, indirect)

– Similar to ISO 27005/FAIR

• Impact estimation– Distribution for amount of impact

• Impact qualification– Relative impact rating

Build your understanding

• Go to http://veriscommunity.net for full details of the framework.

Building Contacts

• While you’re at http://veriscommunity.net join the VERIS mailing list.

• You can ask questions about the framework and specific questions about how to categorize something.

Build your collector

• People, this is just a survey!– Use any of the millions of online survey websites

to make your collector.– Build this thing in Sharepoint and add a workflow

to it.

Pro Tip – Minimize Data Entry

You want source code?

• Tweet

“Oui Kevin! @bfist #BSidesQuebec”

Don’t be afraid to customize!

Sharing is Caring

• Share your data, it makes us all better off.– XML – JSON

• Form partnerships with other organizations and compare incidents.
