Abstract: Cloud computing has become an emerging technology infrastructure in the IT industry. Reasons for the sudden boom of this model were the advantages it offers to the users. Cloud computing is a service over a network connection which shares enormous amount of resources rather than having to build the infrastructure in house. Other than sharing resources cloud computing offers flexibility, reduced capital costs, achieving economies of scale, globalize workforce etc. Cloud computing technology has some serious drawbacks which now has overrun the benefits it offers. The security of the user data is crucial when adopting a cloud computing model. Several methods have been implemented in securing user data such introducing encryption algorithms. Service traffic hijacking creates a major concern on using cloud computing for this allows the hacker to access the credentials of the genuine user hence he or she can eavesdrop on the user’s activities and transactions, manipulate user data, return false information and redirect your client to illegitimate sites. In this paper we propose remediation to prevent intruders of accessing unauthorized data and using and encryption algorithm efficiently to neutralize the security threats.
