What is phishing in the context of data security?

Phishing is defined as a fraudulent attempt to obtain sensitive information, such as usernames, passwords, and credit card details, by masquerading as a trustworthy source. This typically occurs through electronic communications, like emails or messages, which appear to be from reputable organizations. These deceitful interactions often encourage individuals to enter personal information on fake websites that look legitimate, thereby compromising their data security.

Understanding this definition helps emphasize the need for vigilance when interacting with online content and reinforces the importance of verifying the legitimacy of the source before divulging any sensitive information. In contrast to the other choices, which focus on protective measures or protocols, the key characteristic of phishing lies in its deceptive nature aimed at exploiting individuals rather than safeguarding their data.
