Spy-proof enterprise encryption is possible, but daunting
Data encryption could help enterprises protect their sensitive information against mass surveillance by governments, as well as guard against unauthorized access by ill-intended third parties, but the correct implementation and use of data encryption technologies is not an easy task, according to security experts.
Encryption could limit the ability of law enforcement and intelligence agencies to access data without the knowledge of its owner as it travels over the public Internet or by forcing third-party service providers like hosting or cloud vendors to hand it over under a gag order. However, in order for this to work the data needs to be encrypted at all times, while in transit, while in use and while at rest on servers.
The recent media reports about the electronic surveillance programs run by the U.S. National Security Agency (NSA) have raised privacy concerns among Internet users, civil rights activists and politicians not only in the U.S., but also in Europe, Australia and elsewhere.
