For years we have had an expectation of privacy while using our computers, tablets, phones, email, etc. However, with the advent of big data analysis and everything being on the internet, the internet of things, there is no longer the veil that makes up an Expectation of Privacy. Big Data has allowed us to be tracked in new ways and as we add more devices onto the internet, more of our habits will be tracked: Such as location of boats, planes, your mobile device. Purchasing habits, your location within a store, or theme park. Perhaps even your usage of your toaster, house doors, your refrigerator, etc.
Where do we draw the line? Is there such a thing as personal privacy anymore or do we assume we are being tracked everywhere? When does our social media life end and privacy begin? What is considered to invasive?
Christmas is over and New Years is on its way. A time to make resolutions and see the year complete. A time to review what is old and plan for the future. This is a perfect time to review your defense in depth and look to see if there are security additions needed in 2012. So what cloud and virtualization security New Years resolutions should I make for 2012?
In the last Virtualization Security podcast on 12/2 we had with us members of the PCI DSS Virtualization Special Interest Group (SIG). Kurt Roemer of Citrix and Hemma Prafullchandra of HyTrust joined us to discuss the differences to the PCI DSS 2.0 with respect to virtualization. In essence, PCI DSS explicitly calls out the need to bring virtualization, people, and processes into scope.
As we discussed in a previous article, the PCI DSS 2.0 does not state exactly what needs to be assessed within the virtual environment, or even what part of the virtual environment is a concern of each aspect of the PCI DSS. What the PCI DSS 2.0 does do is change the language, however subtle, that technologies employing shared resources are now acceptable.
We’ve recently been asked to look at the way that the Cloud is increasingly being used to provide external security testing services (such as AVS, Application Vulnerability Scanning). The argument of the proponents of such services is that security threats come from the cloud, and thus it makes most sense to embed the AVS in the cloud. However after very detailed examination of the options we have come to the conclusion that the Cloud it isn’t necessarily the right answer for many enterprises, and that the AVS service may best be delivered inside the datacenter.
Application Vulnerability Scanning is the process of exercising the external interfaces to applications (typically public-facing web applications) so as to make sure that there are no exploitable or potentially-exploitable security weaknesses. So, for example, you might want to log on to a system and check that the credentials aren’t just sent back to you in plain text in a cookie.
