Smart city completely employs the new expertise in the development of built-up informatization to enhance the whole city management and service. Smart city collects wide range of information from people and monitor their social activities. However, this arise privacy and security issue in smart city, which is a prevalent concern. Potential threat to privacy and confidential data leads to a myriad of concerns in today’s world, particularly encircling smart city accesses. Previously various methods were used such as SVM, Logistic Regression, Naïve Bayes and more, using large datasets their limitations included lack of accuracy increasing the risk. To tackle the harmful packets from multiple virtual sources an optimal solution of Deep Extreme Neural Network (DENN) expert system is rendered and presented using a dataset of requests received by smart city. Accuracy of 92% is attained. In addition, ample medians of attacks are discussed that can be prevented using the same safety barrier.
