Which of the following actions is important to protect against phishing?

Sharing personal information only on secure websites is a critical action to protect against phishing attacks. Phishing often involves deceiving individuals into providing sensitive information, such as passwords or credit card numbers, through fraudulent websites that resemble legitimate sites. When you share personal information, ensuring that you are on a secure website (indicated by a URL beginning with "https://" and often a padlock icon in the browser's address bar) minimizes the risk of interception by attackers.

By using secure websites, you help ensure that the data you provide is encrypted during transmission, making it significantly more difficult for cybercriminals to capture this information. This practice is part of a broader strategy of remaining vigilant and verifying the legitimacy of websites, which is essential in defending against phishing and other online threats.
