The numbers don't add up.

For example, I get 14 out of 100. Encryption are all 0, yet "Overall" is 3 out of 6. The only other non-zero value is "Number of open ports" (2). 2+3 != 14. Σ0 = 0 != 3.

Obviously, I have no idea what those 12 risk points are. The three encryption points are not explained at all, neither are the remaining nine.
