Never entering personal information on a website that you are not sure is legitimate.
Using a strong password and changing it regularly.
Enabling two-factor authentication on your accounts.

By taking these steps, individuals and organizations can help to protect themselves from phishing attacks.

Weak passwords

Weak passwords are a major cause of data breaches. In fact, a study by the National Institute of Standards and Technology (NIST) found that weak passwords are the number one cause of data breaches. Weak passwords are easy to guess or crack, and criminals can use automated tools to guess passwords or they can use social engineering techniques to trick people into giving up their passwords.

There are a number of things that individuals and organizations can do to protect themselves from weak passwords. These include:

Using strong passwords that are at least 12 characters long and contain a mix of upper and lower case letters, numbers, and symbols.
Not reusing passwords across multiple accounts.
Using a password manager to store and manage passwords.
Enabling two-factor authentication on accounts.

By taking these steps, individuals and organizations can help to protect themselves from the risks of weak passwords.

Here are some real-life examples of data breaches that were caused by weak passwords:

In 2014, the Yahoo data breach was caused by a weak password used by one of the company's employees.
In 2016, the LinkedIn data breach was caused by a weak password used by one of the company's employees.
