Default Asset Score Calculation
Asset scores in Kenna are based on the highest vulnerability that exists on the asset and range from 0 to 1000. All Assets added to Kenna default to a Priority score of 10. The high vulnerability score is multiplied by the Asset Priority to calculate the Default Asset Score.
|Highest Vuln Score||X||Asset Priority||=||Default Asset Score|
Internal vs External IP Enhanced Scoring
External facing assets represent a higher risk and therefore will receiving a "bump" in scoring if detected in Kenna. Assumptions regarding IP network location are based purely on the address itself with 10.*, 172.16.0.0 - 172.31.255.255 and 192.168.* addresses assumed to be internal. IP addresses that appear to be externally routable will have an additional 200 points added to their Default Asset Score with a maximum asset score of 1000.
