A firewall is a kind of network-based security system that analyzes the data that pass through the network to see if that information should be allowed through it. It checks against a set of rules before deciding to allow the passage of data.
Such a trusted barrier has become a necessity in today's networked world. All kinds of personal and business data pass through some form of network, so firewalls are a necessity to protect the security and integrity of data.
This need for improved security has led to many advancements in firewall technology. Today, the manufacturers of firewalls come up with products that are capable of filtering data based on any number of rules. These firewalls have the capacity to handle large amounts of data, which is an important feature because thousands of terabytes of data are being exchanged over the Internet today. With the advent of more sophisticated communication technologies such as big data and social media, this data transfer rate is only going to go up. To meet this demand, manufacturers are making 100 G plus capable firewalls with support for 40 G and 100 G ports.
These advancements are evident in a recent survey conducted by Infonetics. The survey analyzed the firewall capabilities of more than 104 companies, including vendors such as Huawei (News - Alert), Barracuda Networks and Sourcefire.
The results of the survey show that 57 percent of respondents are willing to spend more than $500,000 on powerful firewalls. This is good news for firewall vendors as well as the IT infrastructure industry at large because it signifies a change in mindset among companies. They are willing to spend a lot of money to improve the capabilities of their firewall systems – which is a good sign for consumers as well.
