This is also Dan Hancock's website on Information Security. Dan retired after working years as a
Information Security Officer (ISO) at a Citigroup software development facility. He maintained this
website to record the results of his continuing research in the field and so other ISOs can access it online.
Since his death in 2021, the site has not been updated, but still contains much useful information and sites.
