"Phishing occurs when bad actors use email to pose as reputable websites and login apps in order to acquire sensitive information like usernames/passwords and even banking information. When the employee clicks on the fake website or app and enters their information, it is stolen. I think the best way to avoid being duped by a phishing attempt is education, pure and simple. Employees need to be taught not to click on links in emails, even if they appear legit. They should always type the address directly into a website browser instead of clicking through the link in the email. Within my last role, I set up a system called KnowBe4 that sent test phishing emails to the employees of the company randomly. If they fell for any of them, I was able to follow up and explain why they shouldn't click on an email like that in the future. After several months, the employees were very good at spotting malicious emails. Also, installing a robust firewall and spam filters assists in preventing these kinds of emails from reaching inboxes in the first place."
