Performance and Information Security Evaluation with Firewalls

Abstract

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.

Penetration testing: Concepts, attack methods, and defense strategies

“…Usually, medium and big size companies are exercising penetration testing to prevent outside and inside attacks that would cost more than doing penetration test. A firewall, an antivirus or sensors that are all over the network may not prevent cyber attacks if they do not really know the weakness and vulnerabilities of their system or network [36]. Finally, it is also critical for the security protocols to adopt lightweight cryptographic techniques or use security levels with different ciphers' complexity [32] [33][34] [35].…”

Understanding cloud-based BYOD information security protection behaviour in smart business: in perspective of perceived value

“…Security protection mechanisms increase the system loading an impact on the overall performance. Hayajneh et al (2013) investigated the impact of the evaluation of information security protection mechanism towards overall network system performance. Besides, TTAT focuses on the effectiveness of information security with coping appraisal.…”

Hybrid Encryption Model Based on Advanced Encryption Standard and Elliptic Curve Pseudo Random

“…Thus, the system is not efficacious in terms of using energy, particularly for weak sensors. Hajajneh et al proposed in [3] a cryptographic system that secures multimedia application in FPGA. The goal of this work is to perform authentication and encryption using a Cipher Block Chaining Message Authentication code protocol (CCMP) and a counter (CTR) protocol.…”
