MOD IT SECURITY 2 Le minacce ai dati

The threats to data can be classified based on their origin: natural, deliberate, and accidental. Natural threats include floods, earthquakes, hurricanes, fires, and bombings. Deliberate threats stem from human actions, including those by internal personnel, external agents, and service providers, leading to hardware theft, illegal network access, unauthorized software use, and data copying. Accidental threats arise from unintentional errors by users or maintenance personnel. To prevent unauthorized access, one method is using passwords, which should be at least 8 characters long, alphanumeric, and updated periodically. Another prevention method is data encryption, which ensures secure data transfer and allows only those with the encryption key to decrypt the messages. Lastly, data management software should focus on three key goals: availability (ensuring users can access information), integrity (ensuring data accuracy and reliability), and confidentiality (limiting access to authorized users only).
