Increased encryption a double-edged sword
The Department of Homeland Security may be complaining that encryption is interfering with their attempts to eavesdrop on criminals and terrorists — but they’re not the only ones inconvenienced.
Enterprise security may also be hampered by ubiquitous encryption because it makes it harder to spot when sensitive data is leaving the company, or when malware is communicating with its command and control servers.
Cloud-based email services, online storage sites, and other cloud application providers have already begun encrypting traffic. Even social networks are encrypting traffic. And, recently, Firefox experimented with expanding encryption to more and more of the Web.
