Answer:
One of the biggest problems challenging the US in the 21st century is cyber-terrorism. Cyber-terrorism refers to the use of technology, particularly computers and the internet, to carry out attacks that disrupt or damage computer systems, networks, or information. It poses a significant threat to national security, as it can target critical infrastructure, government institutions, businesses, and individuals.
An example of cyber-terrorism is a Distributed Denial of Service (DDoS) attack, where multiple compromised computers overwhelm a target server, causing it to crash. Another example is a ransomware attack, where hackers encrypt and hold data hostage until a ransom is paid.
The impact of cyber-terrorism includes financial losses, compromise of sensitive information, disruption of essential services, and erosion of public trust. To combat this threat, governments, organizations, and individuals employ various cybersecurity measures such as firewalls, encryption, strong passwords, and regular software updates.
