Understanding Firewalls for Business Security

A firewall is a digital security system that monitors and controls network traffic over our servers to secure them from security breaches. It is like a barrier between a trusted internal network and untrustworthy external networks such as the Internet. Firewalls can be in hardware, software, or a combination of both.

A firewall’s job is to evaluate data packets as they flow through it and decide whether to allow or prohibit them based on rules. These rules can filter traffic based on parameters such as IP addresses, port numbers, protocols, and specific keywords or patterns.

Types of Firewalls 

There are different types of firewalls, each with its own features. Some common firewall types are listed below

1- Packet Filtering Firewalls

The first and most basic type of firewall is a Packet Filtering Firewall, which operations in the network layer of the OSI model. Packet filtering firewalls check incoming and outgoing packets using predetermined rules. These rules guide their decisions about whether to admit or prohibit traffic.

2- Stateful Inspection Firewalls

Stateful inspection firewalls are also known as dynamic packet filtering firewalls. They keep track of the status of active connections and make judgments depending on traffic context. They monitor the status of network connections and filter packets depending on the data in a state table.

3- Proxy Firewalls

Proxy firewalls serve as middlemen between internal and external network connections. They accept requests from internal clients such as web browsers and route them to external servers on their behalf. Proxy firewalls check and filter traffic at the application layer of the OSI model. They offer better security by concealing the internal network structure.

4- Next-Generation Firewalls (NGFW)

NGFWs have better security features that go beyond the average firewall capabilities. They feature intrusion prevention systems (IPS), deep packet inspection (DPI), application awareness, and advanced malware detection capabilities. NGFWs provide visibility and control over network traffic, which protects enterprises against complex threats.
