WORKING SESSION IDENTIFICATION
Short Work Session Description	One of the biggest challenges of running an application security program is assembling the vulnerability findings from disparate tools, services, and consultants in a meaningful fashion. There are numerous standards for classifying vulnerabilities but little agreement on severity, exploitability, and/or business impact. One consultant may subjectively rate a vulnerability as critical while another will call it moderate. Some tools will attempt to gauge exploitability levels (which can be a black art in and of itself), others won't. Tools use everything from CWE to the OWASP Top Ten to the WASC TC to CAPEC. Security consultants often disregard vulnerability classification taxonomies in favor of their own "proprietary" systems. Sophisticated organizations may create their own internal system for normalizing output, but others can't afford to undertake such an effort. Until tool vendors and service providers can standardize on one methodology -- or maybe a couple -- for counting and scoring application defects, they are doing their customers a disservice.
