This week on Ahead of the Threat, the #FBI Cyber podcast, Richard Horne, CEO of the UK’s National Cyber Security Centre, joins Assistant Director (AD) Brett Leatherman for a discussion on cyber threats and practical advice for companies looking to secure themselves against malicious cyber attacks. youtube.com/watch?v=9VyDoFxN…
In this episode’s Top Three Segment, AD Leatherman and #FBI London Cyber Assistant Law Enforcement Attaché Kathryn Sherman discuss the role of FBI personnel stationed overseas in advancing the cybersecurity mission. They question whether a company could operate without its IT for four weeks, noting that if they could not, they were not ready for a ransomware attack. They also dive into the role of private-public partnerships, the burnout of professionals defending networks coupled with the psychologically traumatic effects of being a victimized company, and a reflection on this year’s CyberUK conference, hosted by the NCSC.
