In the contract `GETT0` the role `_owner` has authority over the function `burn()`. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and burn the `_owner`'s tokens. In the contract `MintableToken` the role `owner` has authority over the function `mint()`. Any compromise to the `owner` account may allow the hacker to take advantage of this authority and mint any amount of tokens to the address `_to`. Note the function can only be called once. In the contract `Ownable` the role `_owner` has authority over the functions `renounceOwnership()` and `transferOwnership()`. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and renounce or transfer ownership. In the contract `Pausable` the role `_owner` has authority over the functions `pause()` and `unpause()`. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and pause or unpause transactions.

The **require** can be used to check for conditions and throw an exception if the condition is not met. It is better to provide a string message containing details about the error that will be passed back to the caller.
