Phishing detection is an important part of cyber security. It refers to the process of identifying and protecting against fraudulent attempts to obtain sensitive information such as usernames, passwords, credit card details, etc. through emails or malicious websites. The process involves analyzing emails for suspicious content, detecting malicious links and other indicators of phishing attacks, and alerting users when a potential attack is detected. It also includes monitoring web traffic for signs of malicious activity, blocking access to known malicious sites, and providing remedial action if necessary. By employing effective phishing detection techniques, organizations can reduce the risk of data breaches and protect their customers' sensitive information.
