A Journey to Protect Points-of-sale Nir Valtman ENTERPRISE SECURITY ARCHITECT, NCR RETAIL Many point-of-sale breaches occurred in the past year and many organizations are still vulnerable against the simplest exploits. In this presentation, I explain about how points-of-sale get compromised from both retailer’s and software-vendor’s perspective. One of the most common threats is memory scraping, which is a difficult issue to solve. Hence, I would like to share with you a demonstration of how it works and what can be done in order to minimize this threat. During this presentation, I will explain the long journey took me to understand how to mitigate it, while walking through the concepts (not exposing vendor names) that don’t work and those that can work.
