The 5/31 Virtualization Security Podcast we spoke to High Cloud Security about encryption as a defense in depth, and where to place encryption within the virtual environment. This lead to an intriguing discussion about what is actually missing from current virtual environments when it comes to encryption. We can encrypt within each VM and we can encrypt within the networking fabric, as well as within the drives themselves, but currently that leaves several vulnerabilities and unencrypted locations that can be used as attack points. While we concentrated on vSphere, what we are discussing applies equally to all hypervisors.
The 5/17 Virtualization Security Podcast was an open forum on the Cloud Security Alliance initiatives, specifically the Security, Trust, & Assurance Registry (STAR). Which is “a free, publicly accessible registry that documents the security controls provided by various cloud computing offerings.” The CSA has grown from a grass roots organization to a major player and producer or guidance for security and compliance for clouds.
The 3/22 Virtualization Security Podcast brought to light the capabilities of Symantec Critical System Protection (CSP) software. This software successfully implements a manageable version of mandatory access control policies based on role-based and multi-level security functionality within the virtual environment. More specifically on those systems that are critical to the well being and health of your virtual and cloud environments such as all your management and control-plane tools (VMware vCenter, Microsoft SCVVM, XenConsole, etc.). In addition, Symantec CSP will monitor your virtualization hosts for common security issues. This in itself is great news but why are we just hearing about this now? Is this a replacement for other security tools?
The 3/8 Virtualization Security Podcast held a discussion on the happenings as the 2012 RSA Conference in San Francisco as well as a discussion of the features of Bitdefender’s entry into the virtualization and cloud space with their SVE product. RSA Conference high lights not just those security tools for the virtualization and cloud spaces but the entire industry and each year there is always a common theme. Was there one this year? Was there any surprises at the conference?
The Virtualization Field Day delegates joined the Virtualization Security Podcast as guest panelists on 2/23 and the topic of the day was cloud security. There were questions about compliance, security of the tenant, and security of the administrators, and legal issues. There were answers from Rodney Haywood (Rodos), another Virtualization Field Day Delegate and cloud architect as well as the podcast standard panelists. So what did the questions boil down to?
The 2/9 Virtualization Security Podcast was a discussion on when would one use a virtual firewall. This was in response to being told that there are some people that would never use a virtual firewall for anything, and that got me thinking. Outside of the politics involved with using virtual vs physical firewalls, when would you use one? What are the cut offs, and best practices around using virtual firewalls. We were joined by Rob Randell of VMware to discuss this point.
