Firewalls prevent unauthorized access to your business network and alert you to any intrusion attempts. Use two factor authentication - passwords are the first line of defense against computer hackers but adding a second layer of protection increases security. Many websites allow you to set two-factor authentication, which increases security by requiring you to log in with both your password and a number code given to your phone or email address.
