breach analysis

Mark Rasch, who created the Computer Crime Unit at the United States Department of Justice, has an essay, “Conceal and Fail to Report – The Uber CSO Indictment.” The case is causing great consternation in the InfoSec community partly because it is the first instance in which a CSO or CISO has been personally held…

I want to call out some impressive aspects of a report by Proofpoint: TA410: The Group Behind LookBack Attacks Against U.S. Utilities Sector Returns with New Malware.

Well, Richard Smith has “resigned” from Equifax. The CEO being fired is a rare outcome of a breach, and so I want to discuss what’s going on and put it into context, which includes the failures at DHS, and Deloitte breach. Also, I aim to follow the advice to praise specifically and criticize in general,…

There’s a great “long read” at CIO, “6 Software Development Lessons From Healthcare.gov’s Failed Launch.” It opens: This article tries to go further than the typical coverage of Healthcare.gov.
