摘要：Cloud computing is a new flexible approach for providing higher computational power in shared medium. It provides the distributed model based on self-evaluating techniques to improve the processing capabilities of the system with lesser managerial concerns. It is made up of client, application, platform, servers and infrastructures. This computing model delivers computation capabilities as a calculated service from above components to end users. Though a wide variety of devices and their integration are concerned, priority of handling security will go down. As the users of cloud is increasing day by day one need to handle the data, system and confidentiality issues carefully. So a new security firewall services must be added along with existing system to provide secured access and integrity issues in a cloud environment. Implementing firewall for cloud suffers from various network oriented challenges such as load balancing, scheduling, traffic divergence, filtering, controlling the rate of arrival, instance management, attack detection. Also it is very hard to estimate the response time through a centralized cloud firewall. Thus, a new directional work had been started for practically achieving the new firewall strategies for cloud. It also aims toward achieving the resource optimizing based provisions and rules to lower the price associated with its ownership and operations
