Evolving Threats to Critical Infrastructure. Threats include extreme weather, accidents or technical failures, cyber threats, acts of terrorism, and pandemics. The risk environment is complex and uncertain; threats, vulnerabilities and consequences have all evolved over the last 10 years.
For example, due to the growing integration of information and communication technologies within operations and adversaries focusing on exploiting cyber vulnerabilities, critical infrastructure is increasingly exposed to cyber risks.
The Strategic National Risk Assessment (SNRA) defines numerous threats and hazards to homeland security. In addition to the known risks analyzed as part of the SNRA, the potential for interconnected events with unknown consequences adds uncertainty.
