The recent influx in the deployment of cloud computing can be attributed to large, medium, small enterprises and individuals’ quest to decrease IT cost and overcome economic recession. However, the cloud is still faced with challenges such as data breaches, data loss, malicious insider and denial of service attacks and all point to security of the cloud. This makes security an important discuss in cloud computing, which led to the objectives of this research, which are toevaluate security protocols or measures employed by major cloud service providers and offer recommendations to both Cloud Service Providers (CSPs) and the user.The research employed comparing techniques to evaluate the security measures and protocols employed by the top three cloud service providers which are Microsoft, Amazon and Google. It is worthy to note that, the compute service of CSPs are claimed to be secured as well as their storage services. It is recommended that CSPs provide a 2-factor authentication for users, this ensures that cloud users use very strong password or keys. While cloud users should ensure proper cloud logging and authentication, they should also avoid weak and generic passwords, as weak and generic password makes the cloud susceptible to breaches.
