Cyber has been a point of tension for years

(CNN) Senior cybersecurity officials from the U.S. and Russia are holding meetings this week on cybersecurity, renewing efforts to prevent the countries from mistakenly getting into a cyber war, U.S. officials say.

The meetings in Geneva include officials from the White House, State Department and FBI and will include a review of cybersecurity agreements signed in 2013 by the two countries, a senior administration official told CNN.
