What is the purpose of a firewall in network security?

• The purpose of a firewall in network security is to provide physical protection for the network infrastructure, such as preventing damage from natural disasters.

• The purpose of a firewall in network security is to enhance network speed and performance by allowing all incoming and outgoing traffic without any restrictions.

• The purpose of a firewall in network security is to encrypt all network traffic to ensure secure communication, regardless of the source or destination.

• The purpose of a firewall in network security is to monitor and control incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between trusted and untrusted networks to prevent unauthorized access and cyber attacks.

What is the role of encryption in network security?
