The encryption vs. inspection debate

Thursday 5 October 14:00 - 15:30, Small talks

Nick Sullivan (Cloudflare)

There is a tension in the security industry right now between the proponents of end-to-end encryption and those who use network inspection as a core tool to understand threats and information flows. This debate is particularly relevant to the web, where HTTPS adoption passed 50 per cent this year. Recent research also shows that a large percentage of this traffic is not end-to-end encrypted from the browser to the server, and that both intercepting proxies and anti-virus software can reduce the security of encrypted connections significantly. In this presentation, I will explore the various angles of this debate and entertain ways to relieve the tension.
