Unified Threat Management (UTM) FirewallsĪ packet filtering firewall is the most basic type of firewall.Network Address Translation (NAT) Firewalls.Stateful Multi-layer Inspection (SMLI) Firewalls.Application-level Gateways (Proxy Firewalls).The following are types of firewall techniques that can be implemented as software or hardware: This type of firewall is also called a Host Firewall.īesides, there are many other types of firewalls depending on their features and the level of security they provide. On the other hand, a software firewall is a simple program installed on a computer that works through port numbers and other installed software. A hardware firewall is sometimes referred to as an Appliance Firewall. However, it is best practice to have both to achieve maximum possible protection.Ī hardware firewall is a physical device that attaches between a computer network and a gateway. Each type of firewall has different functionality but the same purpose. Application firewalls can detect DoS attacks and reduce the load of your internal resources.There are mainly three types of firewalls, such as software firewalls, hardware firewalls, or both, depending on their structure.

DoS attacks will be limited to the application firewall itself. Why would you use an application layer firewall?Īdvantages offered by Application Layer Firewalls Application layer firewalls will be able to help in the prevention of most spoofing attacks. What is application level filtering?Īpplication filtering is the most sophisticated level of filtering performed by the firewall service and is especially useful in protecting the network against specific types of attacks such as malicious SMTP commands or attempts to penetrate the local DNS servers.

Application firewalls, or application layer firewalls, use a series of configured policies to determine whether to block or allow communications to or from an app.
