This research paper provides an in-depth study of zero click exploits and malware exploring their techniques, implications and real-world instances. Our primary objective is to offer a clear understanding of the constantly evolving realm of cyber threats, all the while highlighting the pressing need for robust security measures as a bulwark against these sophisticated attacks.

Monolithic architecture is a traditional and primary method for creating software programs. On the other hand, monolithic architecture's shortcomings were addressed by developing the unique evolutionary technique known as microservice architecture, which led to businesses' widespread acceptance of this design. However, the microservice design raises several security concerns, particularly web application security, a significant business problem. The purpose of this study is to analyse and contrast the security and safety features of monolithic and microservice architectures, emphasizing the security issues that each presents and the solutions that have been proposed to address them. Examining both architectures security risks and investigating viable mitigation strategies are covered in the paper. Microservices improve security and flexibility but also need a more complex and dynamic security strategy.
