    December 30, 2016, Shawn Shifflett, CISSP, QSA, Senior Practice Director, PCI

    On Friday, December 6th 2016, the PCI Security Standards Council released their formal information supplement titled, Guidance for PCI DSS Scoping and Network Segmentation.

    November 11, 2016, Bob Post, Senior Practice Director, Cyber Risk Advisory, Coalfire

    In July of this year Verizon announced it was going to buy Yahoo for $4.8B.  A few weeks later, Yahoo starts investigating a potential data breach of around 200 million records that were for sale on the Dark Web.  In mid-September, Yahoo discloses that sometime in 2014, they were attacked and roughly 500 million user accounts were compromised.  A couple of days later, Verizon says this is the first they’ve heard of this and that event may have a “material impact” on the purchase deal.  By October news reports circulate that Verizon may ask for a $1B discount off the purchase price.
