But the ongoing and increasing reliance on the internet underscores the need to understand the risks to its underlying architecture.

Ransomware is a type of malicious attack where attackers encrypt an organization’s data and demand payment to restore access. This Ransomware Profile identifies the Cybersecurity Framework Version 1.1 security objectives that support identifying, protecting against, detecting, responding to, and recovering from ransomware events. The profile can be used as a guide to managing the risk of ransomware events. That includes helping to gauge an organization’s level of readiness to counter ransomware threats and to deal with the potential consequences of events.

The profile can be used as a guide to managing the risk of ransomware.

Federal agencies with a lead role to assist and protect one or more of the nation’s 16 critical infrastructures are referred to as sector risk management agencies (SRMAs). The SRMAs for three of the 16 have determined the extent of their sector’s adoption of the National Institute of Standards and Technology’s (NIST) Framework for Improving Critical Infrastructure Cybersecurity (framework). In doing so, lead agencies took actions such as developing sector surveys and conducting technical assessments mapped to framework elements.
