What is an example of external threats to an ICT system?

An example of external threats to an ICT system includes cyberattacks such as phishing, where attackers impersonate legitimate entities to deceive users into revealing sensitive information. Other threats include malware infections, where malicious software is introduced into the system through vulnerabilities or user actions, and Distributed Denial of Service (DDoS) attacks that overwhelm a system's resources, causing disruptions. Additionally, natural disasters like floods or earthquakes can physically damage infrastructure, leading to data loss and service interruptions.
