Google CSO peers out from the fishbowl to talk security

Steven Max Patterson | March 3, 2016
CSOs would be wise to follow Google’s security operations and strategies because the engineering resources and scale will illuminate pending threats and evolving defenses.

Google’s Vice President Security and Privacy Engineering Gerhard Eschelbeck spoke yesterday to a packed house at the RSA Security Conference about his professional life. Google operates in a fishbowl because its business model depends on both consumers, enterprise users and privacy regulators trusting it to store vast amounts of data in its data centers. Given this scrutiny and gigantic computing scale makes Google intriguing. It’s a benchmark establishing best security practices.

Eschelbeck’s stark mission statement “to protect users’ data” speaks of the alignment of his security group with the company’s cloud services and advertising business model.

Scale at Google according to Eschelbeck is like everything else at Google, it is intense. He said that when he interviewed for his job two years ago he had no idea of the extremes of the responsibility or the scale of the operation. He confessed that when he was asked to estimate the size of Google’s data centers and networks during interviews for his CSO position his estimates were two to three orders of magnitude too low.

Like most security pros, Eschelbeck kept details close to the vest; however he did offer as an example of scale Google’s source code base that he guards both from theft and from intrusion and infection with malicious code. Today’s environment – Google’s source code repository has 2 billion lines adding up to 85 terabyte that 85,000 engineers interact with every day.

Eschelbeck filled in some context to his role with his experience. During his career beginning in the mid-1990s the types of attacks and the defenses evolved in four-year cycles in response to the evolution of platforms. Viruses became worms that became spyware and then ransomeware as networked PCs evolved into a pervasive web of cloud interconnected PCs. Then mobile and now mobile-cloud started a parallel cycle presenting some of the same and new challenges.

He is confident that the cloud security challenges have just about been met. But looking forward to 2020 he sees a huge network of interconnected things that presents yet unsolved problems that need engineering breakthroughs in encryption, authentication and software updates. These challenges should be solved now, not in four years when the systems reach scale.

Eschelbeck has a team of 600 people, half developers and product managers, project managers, administrators and operations. It runs 24X7 and around the world under the assumption that Google’s users and infrastructure are always under attack.

Some members of the Google security team work on building tools to protect the data. Others study the threat landscape, the constantly evolving threats to constantly evolving technologies used by consumers and in data centers. Always mindful of the next exploit they ask the question: what are the new techniques used by the bad actors to which they must respond?
