Define Firewall:
A network security technology known as a firewall application prevents unauthorised users from accessing network sources. By authorising or blocking incoming and outgoing connections depending on protocols, ports, and IP addresses, a firewall programme enables management of the type of website traffic that experiences it.
Firewalls are tools used to monitor and manage the information flow into and out of computer systems within an organisation. They provide protection by allowing authorised users to access corporate resources while preventing unauthorised ones. Moreover, firewalls may be configured to permit access to some services (such as HTTP and FTP) while blocking others (e.g., Telnet).

Still, further precautions must be taken in order to be safe. The following are the difficulties in implementing firewalls:
Firewall operation: This is impacted since each bundle must be verified as real before it is allowed into the organisation.
Infection and malware: A firewall has some limitations, such as the inability to prevent malware and infection attacks at the level of a single framework for distinct applications.
