One of the most essential foundations upon which big institutions rely in delivering cloud computing and hosting services, as well as other kinds of multiple digital services, is the security of infrastructures for digital and information services throughout the world. Distributed denial-of-service (DDoS) assaults are one of the most common types of threats to networks and data centers. Denial of service attacks of all types operates on the premise of flooding the target with a massive volume of requests and data until it reaches a size bigger than the target's energy, at which point it collapses or goes out of service. where it takes advantage of a flaw in the Transport Control Protocol's transmitting and receiving (3-way Handshake) (TCP). The current study's major focus is on an architecture that stops DDoS attacks assaults by producing code for DDoS attacks using a cloud controller and calculating Round-Tripe Time (RTT).

Engineered fills are enhanced by compaction to reduce compressibility and permeability. In-situ application of shallow densification methods involve static method with the use of compaction rollers. However, the compaction characteristics of soils are traditionally obtained in the laboratory using dynamic compaction method. Due to the difference in the mechanism of the two compaction methods, there is a variation in the soil fabric formed, quantification of which is scarce. In this research, influence of compaction effort and (dynamic and static) compaction methods on swell and compressibility of two soils of diverse geological formation are investigated. An indirect means of measuring microstructural changes in specimen characteristics using electrical resistivity is also investigated. Results indicate that the compaction effort and the method of compaction have a significant impact on the electrical resistivity and swelling potential. The yield stress of the compacted specimens is also influenced. However, the compressibility and rebound behaviour upon unloading, are obtained to be independent of both the compaction effort and the method of compaction.
