Anti-phishing refers to techniques and tools designed to protect users from phishing attacks, which are fraudulent attempts to obtain sensitive information like passwords or credit card numbers. These attacks often come in the form of deceptive emails or websites that appear legitimate, tricking individuals into providing their personal data. To combat phishing, organizations implement various strategies, including user education, email filtering, and the use of security software. Technologies like two-factor authentication and SSL certificates also enhance security by ensuring that communications are encrypted and verifying the identity of websites, making it harder for attackers to succeed.
