Google Airs Its Cloud Security

Thinking of breaking into Google's datacenters to steal information? Think again.

The company opened up a little about how it physically secures one of its datacenters within its global cloud network. The security measures are described in both a Google blog posted on Friday and in an interesting YouTube video that actually shows the interior of a Google datacenter. The video represents a rare glimpse because Google doesn't permit public tours.

The physical security measures shown in the video include restricted access via fencing and checkpoints, badges that are difficult to forge, and even iris scans. In addition to humans scanning the perimeter using cameras located across the datacenter's grounds, there also are automated systems to help weed out the unwanted. Google uses other security methods too that it doesn't disclose.

And you can forget about dumpster diving to snag data, something that Paul Allen and Bill Gates used to do to DEC's trash in their early Micro-Soft days. Data stored on hard drives in Google's datacenter get wiped and then the hard drive is physically crushed before disposal. Google also uses a drive shredder that spits out chunks of mashed up hard drives, which then are sent out as scrap for recycling.

Since it's Earth Day today, there was the usual discussion about power-saving issues associated with running datacenters. Google claims in the video that in 2009 it achieved the most stringent standards for datacenter power efficiency that was set by the U.S. Environmental Protection Agency. Google taps wind energy to power its datacenter in Oklahoma and has invested $350 million in other renewable energy projects, according to this Google blog.

Not to be outdone on Earth Day, Microsoft continues its messaging that cloud computing use will actually save the planet's use of energy resources. A Microsoft blog floats the statistic that IT constitutes two percent of energy use worldwide. Cloud computing can help reduce the other 98 percent of energy use, Microsoft's blog contends. The blog does admit that cloud computing "comes with a serious energy and carbon cost," but it suggests that running applications through the cloud will save overall power consumption in the long run.

The environmental organization Greenpeace contends that most cloud computing companies, such as Google and Microsoft, simply use dirty energy derived from coal and nuclear sources. Greenpeace recently published a report, "How Dirty Is Your Data" (PDF), and called on datacenter companies to be more transparent about their energy use and carbon footprint. The report gives Google an "F" and Microsoft a "C" on transparency.

Matt Rosoff at the Business Insider has noted that Facebook rolled out a new energy-efficient datacenter, but Facebook has been far more open than Google about the details. Facebook went open with its practices by establishing an Open Compute Project.

Certainly, Google and Microsoft aren't the only two cloud service providers on the planet, but they have been in the spotlight lately as they battle to win contracts at the federal level. Those battles -- which could open up massive customer-scale scenarios limited only by the size of government itself -- also involve security concerns. However, the security is wrapped around the Federal Information Security Management Act (FISMA). FISMA is a kind of blueprint indicating what government agencies should do to ensure security on their systems.

After a public spat over FISMA certification and accreditation approvals, both Google and Microsoft are now entering a phase in which they will start providing cloud-based services to U.S. government agencies on a broad scale. Microsoft's datacenters, and now some of its cloud-based apps, have already received authorization to operate based on FISMA criteria.

Google's cloud-based apps, called "Google Apps for Government," are getting reviewed for additional security controls. However, the government has basically indicated that they pass the FISMA test.
