In the contract `Ownable` the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority to transfer ownership of contracts using the `transferOwnership()` function.  In the contract `Pausable` the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority to pause and unpause contracts using the `pause()` and `unpause()` functions.  In the contract `PausableToken` the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority to add or remove addresses from the blacklist via the `blackListAddress()` function. 

In the current implementation, the total `totalSupply` is minted to the `tokenOwner`. This introduces a possible centralization risk that all tokens are controlled by a single person. Any compromise to the private keys of the `tokenOwner` could lead to the loss of assets.
