What’s New: Last week’s summit between President Biden and Russian President Putin included “clear” and “productive” talks about cybersecurity and establishing “rules of the road” for online espionage.

Why This Matters: A number of high-profile cyber operations — including the recent SolarWinds supply chain hack and the ransomware attack against the Colonial oil pipeline — have been attributed to the Russian government or actors who enjoy tacit approval by Moscow.
