The Evolution of an Important Metric: The Poverty Line

by Marcus J. Ranum on May 1, 2014

In this blog series on SecurityWeek, Tenable CSO Marcus Ranum advises security professionals on how they can create and share metrics in their jobs. These metrics can create better understanding and awareness about the success of their approaches, as well as allow them to build support for programs and funding requests. Keeping with the definition that a metric is used to tell a story, let's look at an influential metric and how it was established, as well as a few things about how it has been historically presented. I'm going to use the metric as a way of red-flagging a few “don’ts” in...

Five 'Truths' About PCI Compliance and Cybersecurity

by Jeffrey Man on April 28, 2014

Posted originally on Wired, InnovationInsights blog In my last blog, I dispelled three common misconceptions about the Payment Card Industry (PCI) Data Security Standard. And to lend further insight about PCI — especially with regard to its impact upon your cybersecurity assurance — I’d like to share five "truths" that you must know about your approach to cybersecurity and PCI compliance: Never separate PCI compliance from your overall security efforts. Many organizations make the mistake of putting PCI in some kind of box, practically removed from the security program. But PCI is a data...

The Truth Behind Three PCI 'Myths'

by Jeffrey Man on April 22, 2014

Posted originally on Wired, InnovationInsights blog In Part I of this series of posts, I examined how retailers face immense challenges with respect to their cybersecurity posture but don’t often focus on the important elements. For starters, they will spend an inordinate amount of time struggling to "reduce the scope" of their enterprise that needs to comply with the Payment Card Industry (PCI) Data Security Standard. Then, when they are found to be compliant, they too often discover (the hard way) that their bare minimum approach to PCI compliance has left them still vulnerable to exploits...

Nessus Amazon AWS Auditing Now Available

by Mehul Revankar on April 22, 2014

Edits and Contributions: Paul Asadoorian The transition to cloud services is well underway, bringing with it traditional and new security challenges. Nessus is evolving to address these challenges. Unlike traditional environments, cloud services require a modified approach to scanning - users can't simply point their scanners to services such as Amazon AWS, and not expect to be throttled, if not outright blocked. Today we are happy to announce Nessus support for auditing Amazon AWS infrastructure. This new capability in Nessus ® includes a compliance plugin and a .audit file that leverages...
