Hi.

The Springboard source is not a blog; it is a column by Windows IT Pro, and it is written by Paul Thurrott. It has all three elements of a reliable source: Credible author, credible publisher and contents itself. 

Unlike what you think, it was not a set of "abstract techniques"; it was tangible changes visible to laymen end-user ([[a new version of Windows Firewall, a new version of Internet Explorer 6 and the famous Windows Security Center.) Windows XP Service Pack 2 was in important milestone because at the time Microsoft was under full-scale global scrutiny about the state of security in its products. Windows XP Service Pack 2 was a security facelift in Windows XP, so there is little surprise its security portion has its own codename.

Best regards,
