Mum's the word

Q How do you get 500 people to keep a secret?

A By using onion layering

Onion layering is one of the most effective methods of implementing security because even if you get through one layer, there's another layer underneath, and another one and another one etc until you eventually reach the inner sanctum. However that takes a lot of time and only the really determined would put in the requisite effort.

By the end of the Second World War about 500 people worked in the Cabinet War Rooms, but by using another security principle called need to know the actual number of people who really knew what was going on was limited to a handful.

The original axis of evil, Germany, Japan and Italy did not have a flippin' clue about this room from where Britain plotted the demise of the Third Reich. Don't the British know how to keep schtum?!

The Cabinet War Rooms and the Churchill Museum are well worth a visit and you can see the ingenuity of the Royal Engineers on display.

Churchill was an admirer of the Desert Fox aka Erwin Rommel - he admired his professionalism as a soldier. FDR was the glue that held Stalin and Churchill together so when he died on 12 April 1945, the fractious relationship between Stalin and Churchill re-emerged. Churchill did not have as close a relationship with FDR's successor, Harold S Truman.

Oh, why was I there? To attend an information security seminar - what a way to combine business and pleasure?! I'm a history buff so the tour after the seminar was the proverbial icing on the cake.

PS: Stalin killed a lot more people than Hitler, 20 million to 6 million, so why is Hitler the more vilified? Is Hitler's continued condemnation based on how society values human lives? We all know an African life isn't worth very much. Or could it simply be that as Stalin was on the victorious side, he was entitled to his spoils of war?!
