Double spending attacks and block depth.

[No_2]

Am I correct in my understanding that a bitcoin transaction which has been mined into a block and becomes six blocks deep in the chain (has six confirmations) is statically very secure from a double spending attack?

If not can someone point me at info explaining why not.

tl;dr you need to outpace the network to generate enough fake blocks.

Which requires >50% of the total hashing power on the bitcoin network? (Or arguably less according to some recent papers?)
