Ranking Threats by Decreasing Risk

Commerce Server 2002

For each asset in your Commerce Server installation, prioritize possible threats by determining the following:

  • What is the chance of an attack occurring? That is, how much effort/cost/time would be required to mount the attack? 1 = high chance, 10 = low chance
  • What is the cost or damage to your site if an attack occurs? 1 = little damage, 10 = massive damage
  • Risk = Damage if an attack occurs / Chance of attack. 1 = little risk, 10 = massive risk

To reduce the risk to your Commerce Server installation, address the high-risk items first. When you do this, keep in mind the industry statistics in the following table. They show the current vulnerability distribution by cause of seven major threats.
