Sep 22, 2004

Appl. No.:

10/947575

Inventors:

Jeremy Kelley - Leander TX, US
Jeffrey Lahann - Erie CO, US
David Mackey - Longmont CO, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 9/32

US Classification:

726003000

Abstract:

A method, system and computer program product is disclosed that provides timely, accurate and summarized information about possible threats to information technology environments. It is a tool that looks at multiple aspects of an IT threat, including both specific (traditional) IT threats and general (non-traditional) IT threats, and rates each threat's overall potential to do harm. A matrix is created that identifies a “threat score” to allow prioritization and reaction to the threats. The matrix takes both traditional IT threats and non-traditional IT threats and normalizes them on the same scale, giving users of the matrix the ability to understand the risks of both.
