After a series of extremely damaging ransomware attacks believed to have originated in Russia; US President Joe Biden warned Russian President, Vladamir Putin, that the US no longer views such attacks as just criminal activity; but now also as threats to our national security.

Then, just one day after that warning; the Russian hacker group believed to be responsible for it, REvil; suddenly disappeared from the web. How and why is still a mystery, but what is certain, is that damaging attacks like the ones they launched recently will continue-whether or not that particular group is to blame.

So, what can we do to protect ourselves?

I talked to two experts, including Computer Science Professor, Dr. John Nicholas, who teaches Cybersecurity at the University of Akron, and author, Thomas Parenty, who shares insights from his new book, "A Leader's Guide to Cybersecurity: Why Boards Need to Lead, and How to Do It.'

Parenty has 35 years of cybersecurity experience, including work for the US National Security Agency (NSA), where he focused on protecting global nuclear command and control networks from foreign cyber attack.
