A strong and upgraded firewall protection acts as a virtual barrier that defends external and internal damages from cyber attacks. Installing a powerful firewall protection on your system or network, provides you low-level protection against malware, identity theft or other cyber attacks along with the login and auditing procedures. There are several forms of firewall, each having their own specific functions to perform. Broadly, firewalls are of two types- host-based and network based. A host-based firewall protection is installed on the user's computer or server to monitor the incoming and outgoing signals. On the other hand, a network-based firewall is installed over a network or cloud's infrastructure to control and protect the data being transmitted from one host to another on a network. A network-based firewall is also referred as a virtual firewall service.
