Ever since the Snowden papers, it seems even nations are paranoid. A memo from Christophe Chantepy, chief of staff to French prime minister Jean-Marc Ayrault, recommends French cabinet ministers stop using smartphones for phone calls because they are not secure.

The following are the rules that the paper suggests ( some loosely translated ):

• BYOD is forbidden
• Mobile phones are a bad idea: landline phones secured by Thales' TEOREM technology for voice calls are far better idea
• Smartphones should be secured by French spook house ANSSI before being used for anything
• ANSSI will make sure you encrypt everything
• TXT? Fuggedaboutit!
• Intranet-based secure email is mandatory for even low-level secrets
• Computers and phones should be in the same room as ministers when overseas, and beware snooping when abroad
• Twelve-character passwords please, using letters and numbers, changed every six months and use different passwords for personal and work devices please!
• Are you sure that attachment is safe to click on? Don't unless you are.

The edict, though not suggesting any snooping, does remind us that spies are everywhere.
