31 Jul 2007: Common Platform Enumeration

Although Red Hat is well known for Red Hat Enterprise Linux we actually have a large number of other supported products, both layered on top of Enterprise Linux (like Red Hat Application Stack) and stand-alone (like Red Hat Directory Server). The majority of these products are serviced through the Red Hat Network and get our security advisories in a standard way and are included in the Security Response Team metrics. But our analysis scripts were not particularly consistent in dealing with product names.

Common Platform Enumeration (CPE) is a naming scheme designed to combat these inconsistencies, and is part of the 'making security measurable' initiative from Mitre. From today we're supporting CPE in our Security Response Team metrics: we publish a mapping of Red Hat advisories to both CVE and CPE platforms (updated daily) and you can use CPE to filter the metrics. Some examples of CPE names:

cpe://redhat:enterprise_linux:5:server/firefox -- the Firefox browser package on Red Hat Enterprise Linux 5 server.
cpe://redhat:enterprise_linux:3 -- Red Hat Enterprise Linux 3
cpe://redhat/xpdf -- the xpdf package in any Red Hat product.
cpe://redhat:rhel_application_stack:1 -- Red Hat Application Stack version 1
