what networking device often uses signatures to help protect a network from known malicious attacks

Enterprise$-$grade Firewall: A large organization may require a more robust and scalable solution, such as an enterprise$-$grade firewall. These firewalls are designed to handle high volumes of network traffic and provide advanced security features.

Multiple Firewalls: Due to the size and complexity of the network infrastructure, a large organization may deploy multiple firewalls at different network entry points. This can include firewalls at the perimeter, between internal network segments, and for specific applications or services.

Intrusion Detection$/$Prevention Systems $($IDS$/$IPS$)$: In addition to firewalls, large organizations often implement IDS$/$IPS systems to detect and prevent network attacks. These systems can work in conjunction with firewalls to provide enhanced security.

Centralized Management: Large organizations may utilize centralized management systems to configure and monitor their firewalls. This allows for consistent policy enforcement across multiple firewalls and simplifies the management of a large network.

In summary, while both small and large organizations can implement firewalls to
