You are vulnerable to Social Engineering (and almost everyone is), no security of any kind will ever work. Become a Scottish crofter, it's your only hope of a life.
You are a private individual, see all XKCD coverage. Same remedy.
You are Sony, abandon hope now. You wouldn't even make it as a crofter.
You are anyone else, encryption is not enough. You want segmentation, active NIDS, proxies and firewalls at the gateways, HIDS on the machines, role-based access controls, host-to-host IPSec, security labels on packets, total removal of all vulnerable protocols, disk encryption, strong authentication and Neuromancer's Black Ice. A platoon of extreme freediving Ninja with enhanced magnetic sensors in their eyeballs would help, too.
