Cyber Attack

The US has reported finding a large number of Trojan horses and trap doors hidden in there national grid systems, and found a lot of malware, not coming from the United States but somewhere else. The computers controlling the Electricity grids in both Britain and the United states are constantly sending messages to one another over the internet; this is so they can balance the supply with demand. The only problem is that this then allows hackers the capability to gain access to critical systems.
The UK government does not have the funds or resources to update critical systems, and its only a matter of time before someone shuts our Grid down.
An attack on the UK National grid could cause a severe State of Emergency. Imagine No Power, Heat, Food or water for 2 weeks. Society would start to fall apart, people would become desperate. 

 Do you have the basics at home to Survive a 2 week power outage?
