Reflecting on Cybersecurity from 2015 to today

I spoke to the APEX Technical Committee back in 2015 on Aviation Cybersecurity. What happened in the last 11 years? ARINC 848 Media Independent Secure Offboard Network (MISON) was published. ATN/IPS emerged as the sanctioned ACARS-over-IP protocol. VLAN ID has proliferated as a the preferred method for network slicing. Aviation-ISAC has remained the focal point for cybersecurity tactical coordination. Sadly, OpenSSID remains the standard for IFC Wi-Fi, with very good alternatives still on the bench. Occasional hiccups persist with EFB software, and its influence to aviation safety remains blurred on the edge.

Here is the video from my 2015 talk. While I know many will not take the time to watch the video, I hope you have a chance to checkout the cast discussed at the outset. I spent quite a bit of time preparing that segment by coming up with images where I got to play each cast member.

Tomás Romero (taken from us too soon, RIP) wrote an article from that 2015 session on Runway Girl. Here is a link to the article.

Peter Lemme has been a leader in avionics engineering for 45 years. He is the thought leader to the Seamless Air Alliance. He offers independent consulting services largely focused on avionics and L, Ku, and Ka band satellite communications. Peter chaired the SAE-ITC AEEC Ku/Ka-band satcom subcommittee for more than ten years, developing ARINC 791 parts 1, 2, and 3; ARINC 792, Project Paper 793, and continues as a member. He also contributes to the Network Infrastructure and Cybersecurity (NISC) subcommittee.

 

Peter was Boeing avionics supervisor for 767 and 747-400 data link recording, data link reporting, and satellite communications. He was an FAA designated engineering representative (DER) for ACARS, satellite communications, DFDAU, DFDR, ACMS and printers. Peter was lead engineer for Thrust Management System (757, 767, 747-400), also supervisor for satellite communications for 777, and was manager of terminal-area projects (GLS, MLS, enhanced vision).

 

An instrument-rated private pilot, single engine land and sea, Peter has enjoyed perspectives from both operating and designing airplanes. Hundreds of hours of flight test analysis and thousands of hours in simulators have given him an appreciation for the many aspects that drive aviation; whether tandem complexity, policy, human, or technical; and the difficulties and challenges to achieving success.
