September is National Preparedness Month

National Preparedness Month is a good opportunity to assess your emergency preparedness. While general preparedness is essential to getting through an emergency related to a natural disaster, the same is true of preparing for a cyber-related event, such as identity theft or a ransomware infection.

NCCIC encourages users and administrators to be prepared in case of a cyber-related event by regularly backing up files, keeping digital copies of important documents somewhere other than your computer (e.g., in the cloud), and regularly running antivirus scans.

Learn more about individual and family emergency preparedness at Ready.gov. For additional resources on preparing for and responding to unexpected cyber-related events, see Ready.gov/Cybersecurity and the following NCICC Tips:
