Ransomware Prevention Tips

We have compiled a list of security measures to implement to either prevent ransomware or limit the damage. Organizations need not implement all of these in order to prevent ransomware. However, these are various strategies that can be implemented depending on the company. Security measures such as "application whitelisting" will prevent most malicious software on its own.  Overall, most of these strategies are best practice and should be implemented as part of a larger security framework such as SANS Critical Controls.
