9697In order to determine the severity of a security issue we take into account
9798the complexity of any potential attack, the impact of the vulnerability and
9899also how many projects it is likely to affect. This score out of 15 is then
99100converted into a level of: Low, Medium, High, Critical, or Exceptional.
