摘要

ABSTRACT Denial-of-service (DoS) and distributed denial of service (DDoS) are the main threats in the cyber security to deny these attack many techniques has been introduced some of the techniques are related to cryptographic and some of them is based on web application[1][4]. Based on these many techniques has been introduced some of the techniques is more secure but not interoperable and some provide reliability but it is not secure so to find the features in these techniques survey is created.
