• Ransomware: encrypts files and demands payment for decryption.

There are several types of firewalls, including network firewalls, host-based firewalls, and application firewalls.

• Network firewalls filter traffic between two or more networks and operate at the network layer of the OSI model.

• Host-based firewalls are installed on individual computers and control traffic in and out of that specific device.

• Application firewalls filter traffic at the application layer of the OSI model an...read more
