Firewalls are an essential part of any information security system being the rst defense line against security attacks. The sea-saw eect between rewalls 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 rewall platforms and their impact on network performance is important when assessing the eectiveness of network security. In this paper, we present an assessment methodol- ogy to analyze the performance of dierent rewalls platforms. The analysis considers the following metrics: delay, jitter, throughput, and packet loss. Moreover, the information security of the rewalls is also tested by applying a set of attacks and observing the reaction of the rewalls. The proposed assessment methodology is tested by performing real exper- iments on dierent types of rewalls 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 rewall and their use.
