Firewalls are an essential part of any information security system being the first defense line against security attacks. The sea-saw effect between firewalls and network performance is most concerning to network users; where strict security settings result in weak network performance and permeant security settings allow for a stronger one. Hence, evaluating firewall platforms and their impact on network performance is important when assessing the effectiveness of network security. In this paper, we present an assessment methodology to analyze the performance of different firewalls platforms. The analysis considers the following metrics: delay, jitter, throughput, and packet loss. Moreover, the information security of the firewalls is also tested by applying a set of attacks and observing the reaction of the firewalls. The proposed assessment methodology is tested by performing real experiments on different types of firewalls including those that are personal and network-based. Moreover, a quantitative study is conducted to explore the level of knowledge among the educated category in the community, represented by a sample of college students, on the importance of firewall and their use.
In REF researchers evaluated different types of firewall platforms and their effects on network performance.
