Juniper Firewall Fundamentals: Your Gateway to Network Security

Protecting an organization's network is important. And therefore, it becomes essential for the organization to implement a firewall that has advanced features for securing a network from unknown threats. There are many different types of firewalls, like packet filterers, circuit-level firewalls, state Ful and proxy firewalls, and next-generation firewalls. All types of firewalls protect a system from threats, but the next-generation firewall does not only protect a system but also takes action against those suspicious threats. Next-generation firewalls are the most renowned firewalls that are used in small, medium, and large organizations, and the reason behind this is that they provide extra security features like detecting and eliminating viruses from a system, deep packet inspection, web filters, and many more.
