DEFENSE MECHANISM AGAINST DDOS ATTACK IN CLOUD COMPUTING ENVIRONMENT

Abstract

The distributed denial of service (DDoS) attacks in cloud computing requires quick absorption of
hacked data. To increase the security issues in a private cloud storage server and to prevent the user
data from attacker we propose efficient techniques which we use the blocking algorithms to block the
attackers and generate a attacker tracing technique to trace the presence of the attackers who were
involved in the process. The proposed methodology is suitable for a private cloud storage which can be
modified in future to support public clouds. If an user uploads his data to a cloud storage server the
user will be provided with a private key and as well as the public key. The public key is used verifies
that the user belongs to the concerned private cloud. In case of any abnormal activity in the user
account or user tries to access the private cloud data without the knowledge of the cloud data owner the
proposed methodology revocates the specific user using IP address and provides the longitude and
latitude information to the data owner. Additionally, we propose pattern matching, SQL injection and
anomaly detection to maintain the privacy and security for the user data that has been implemented
