Now-a-days, all are working with cloud environment. The massive jumps in technology led to the expansion of cloud computing as the most accepted medium for communication but it has also increased the scope of attacks. So security has become a major issue for cloud environment. Intrusion detection systems have become a needful component in terms of network security. Cloud computing environment is threatened by different types of cyber-attacks. The proposed architecture provides implementation of Suricata intrusion detection system to secure virtualized server in cloud platform and validated intrusion detection system in detecting DDOS attack against the virtualized environment and protect cloud efficiently from vulnerability.
