Can the cloud protect us from cyber attacks? Or does it just make us more vulnerable? The early days of cloud computing raised deep concerns among I.T. experts about cybersecurity. Wasn't it riskier to shift systems and data to shared servers that lay beyond the firewall? What's more, system designers seemed to be doing little to insure security in the cloud. But that attitude is changing. Today, the cloud can serve as a potent weapon against security breaches and ''threat actors.'' So says Jeff Schilling, chief security officer with Armor Defense, Inc. On this episode, he talks about recent advances in cloud security, and how the technology can help to ''censor, contain and eradicate'' hackers and cyber thieves. He offers advice to companies on what they should be doing to protect their data, funds and intellectual property in the cloud. He lays out the biggest vulnerabilities that still exist in I.T. systems. And he suggests an answer to the unsettling question: Is anybody truly safe?
