Firewall products come packaged in various forms. These products use different techniques for determining what will be permitted or denied access to a network. They include the following:

+ Packet filtering – Prevents or allows access based on IP or MAC addresses
+ Application filtering – Prevents or allows access by specific application types based on port numbers
+ URL filtering – Prevents or allows access to websites based on specific URLs or keywords
+ Stateful packet inspection (SPI) – Incoming packets must be legitimate responses to requests from internal hosts. Unsolicited packets are blocked unless permitted specifically. SPI can also include the capability to recognize and filter out specific types of attacks, such as denial of service (DoS)
