Question: 1 / 400

What is the primary purpose of a firewall?

To speed up network connections

To prevent unauthorized access to or from a private network

The primary purpose of a firewall is to prevent unauthorized access to or from a private network. A firewall acts as a barrier between your internal network and external sources, monitoring incoming and outgoing traffic based on predetermined security rules. This helps to block malicious traffic, unauthorized users, and potential threats from entering the network, thus protecting sensitive data and maintaining overall security.

While options related to enhancing performance or storing data may involve network considerations, they do not align with the fundamental role of a firewall. Speeding up connections or enhancing application performance is not the firewall's objective; its main focus is on protecting the network's integrity and security.
