One of the real challenges facing the emerging field of software security is the lack of an easily accessible common body of knowledge. We describe a software security portal that the USA Department of Homeland Security (DHS) National Cyber Security Division (NCSD) is developing (along with the Carnegie Mellon Software Engineering Institute (SEI) and Cigital). The launch of this portal is scheduled for October 2005 as part of the US-CERT Web site. The portal aims to provide a common, accessible, well-organized set of information for practitioners wishing to do software security.
