Full Description
Protect Your Organization from Devastating Ransomware and Cyber Extortion Attacks
Ransomware and other cyber extortion crimes have reached epidemic proportions. The secrecy surrounding them has left many organizations unprepared to respond. Your actions in the minutes, hours, days, and months after an attack may determine whether you'll ever recover.
You must be ready. With this book, you will be.
Ransomware and Cyber Extortion is the ultimate practical guide to surviving ransomware, exposure extortion, denial-of-service, and other forms of cyber extortion. Drawing heavily on their own unpublished case library, cyber security experts Sherri Davidoff, Matt Durrin, and Karen Sprenger guide you through responding faster, minimizing damage, investigating more effectively, expediting recovery, and preventing it from happening in the first place. Proven checklists help your security teams act swiftly and effectively together, throughout the entire lifecycle--whatever the attack and whatever the source.

Quickly recognize indicators of compromise
Minimize losses with faster triage and containment
Identify threats, scope attacks, and locate "patient zero"
