Cloud security is a critical area of research due to the increasing adoption of cloud services and the sensitive nature of data and applications hosted in these environments. Intrusion Detection and Prevention Systems (IDPS) play a pivotal role in maintaining the integrity, availability, and confidentiality of cloud infrastructures.As cloud environments grow more complex with the adoption of technologies like microservices, containers, and hybrid clouds, research in this area must address scalability, real-time threat detection, and performance challenges. Emerging technologies such as AI, blockchain, and federated learning offer exciting opportunities to develop more adaptive and resilient IDPS solutions. Additionally, balancing security with privacy preservation and user experience is critical for securing multi-tenant and shared cloud infrastructures. As threats continue to evolve, these research directions will play a crucial role in safeguarding cloud environments and ensuring trust in cloud-based services.
