Re: Protection Profiles for PoS
Less technical notes - many POS devices years ago had an XP version called 'Embedded" - never had a chance to work on one of these different systems but I wonder who was in control - who supported them?  I presume the retail store itself or parent firm has a support conract and how often, and this is frightening, do their staff visit a retail store for upgrades and review.  Never knew.  Kroger has POS stations of course and about 2 yeas ago they were upgraded from (god forbid) Windows NT ----- true, I recongized the OS screen easy ---- to Windows 7 and that was a nightmare for 2 weeks.  Again - WHO supports these devices.  And Every Kroger has four of them.  I have seen in Atlanta internet attached parking meters!!!   True - debit card, swipe and there you go.

Protection Profiles for PoS
In a 2014 paper on PoS protection profiles [1] the authors point to the failure of PoS companies in general to comply to any given standard (including, I assume, the EMV) or, despite trying to comply, still end up getting hacked.  There is no guarantee of security when an organization uses a standard such as EMV; failure points exist across the PoS ecosystem, not just at a single point.  The paper focuses instead on a protection profile for PoS based on Common Criteria (CC) with the goal of developing security functional requirements for PoS systems that are more robust, more likely to produce a secure PoS system and are not limited to a specific country's standard for security, but drawn from an international standard (ISO/IEC 15408).  While many standards from each country who have written them for PoS security reference or draw from CC, the importance of having mandatory security functional requirements based on the CC (ISO/IEC 15408) that are NOT rooted in any one country's interpretation or implementation is critical to higher levels of PoS security globally.  As the paper concludes, this aids in making the most objective evaluation of the security of a PoS system possible.

Everything You Need to Know About DNS Attacks
It's important to understand DNS, potential attacks against it, and the tools and techniques required to defend DNS infrastructure. This report answers all the questions you were afraid to ask. Domain Name Service (DNS) is a critical part of any organization's digital infrastructure, but it's also one of the least understood. DNS is designed to be invisible to business professionals, IT stakeholders, and many security professionals, but DNS's threat surface is large and widely targeted. Attackers are causing a great deal of damage with an array of attacks such as denial of service, DNS cache poisoning, DNS hijackin, DNS tunneling, and DNS dangling. They are using DNS infrastructure to take control of inbound and outbound communications and preventing users from accessing the applications they are looking for. To stop attacks on DNS, security teams need to shore up the organization's security hygiene around DNS infrastructure, implement controls such as DNSSEC, and monitor DNS traffic
