You are concerned about attacks directed at your network firewall. You want to be able to identify and be notified of any attacks. In addition, you want the system to take immediate action to stop or prevent the attack, if possible. Which tool should you use

Intrusion Prevention System (IPS)

Explanation:

Firewall can be defined as a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.

Simply stated, a firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.

A firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access.

Basically, it is a network security device or security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer

Thus, the tool you should use is an intrusion prevention system (IPS).
