ABSTRACT

Cloud computing has brought many benefits to the IT industry, and it can reduce cost and facilitate business growth especially for startup companies that do not have enough financial resources to build their own IT infrastructure. One of the main reasons why companies are reluctant to use cloud services is the security issues that cloud computing technology suffers from. This paper contains the concept of cloud computing, reviews security vulnerabilities in cloud computing according to security standards, explains denial of service attacks in the cloud and will focus on HTTP DOS attack. HTTP slow rate attacks were chosen because of their ingenuity and also their disastrous impact. There is some research on the different way a web server or web service can be protected from slow HTTP attacks, but there is a lack of research on the impact of an attack on a cloud computing virtual environment or whether or not such an attack has a cross impact on the virtual machine. This study investigates the impact of a slow HTTP attack on the cloud virtualization environment and will analyze the direct and indirect impact of these attacks. To analyze slow HTTP attacks, using the opnet program to analyze the impact of the attack, the attacks are initiated by measuring object response time, page response time, sending and receiving traffic (bytes/sec), sound (jitter (sec), MOS value, packet Delay) Cloud Computing QoS Assessment.
