7 6 Federal Aviation Administration Airborne WiFi in the News

8 7 Federal Aviation Administration ‘Original Article’

9 8 Federal Aviation Administration AAtS Threat Portals Spoofing identity Information disclosure Elevation of privilege Denial of service Tampering with data Repudiation

10 9 Federal Aviation Administration Threat Categories & Descriptions Threat Number CategoryDescription TS-1 DImproper traffic originating from the EFB TS-2 E, DCabin gaining unauthorized access to DLS TS-3 E, TCabin user gains unauthorized access to Wireless Access Point TS-4 DConsumption of DLS Bandwidth TS-5 S, I, DUnauthorized Network Mapping by Authenticated User TS-6 S, E, DExternal Attacks with IP Address or Hostname TS-7 DWireless Access Point/Router DoS TS-8 S, E, IRogue access point impersonating Wireless Access Point TS-9 S, DEFB may make excessive queries, conducting a DoS TS-10 IUser in the cabin sniffing flight deck traffic TS-11 S, T, I, EAttack on the Certificate Authority and Rogue Certificates

11 10 Federal Aviation Administration FAA Risk Assessment Matrix Safety Risk Assessment Matrix from FAA ORDER A

12 11 Federal Aviation Administration Threat Scenario Risk Assessment Assessed Risk Number of Threats Unacceptable risk0 Acceptable Risk with Mitigations 5 Acceptable risk 6

13 12 Federal Aviation Administration Conclusions The ERAU report presents several interesting network security threat scenarios. There may be others... Threat Scenarios 1 thru 11 do not represent either Hazardous or Catastrophic risk severity from an operational perspective. We are continuing to evaluate this important issue.
