A Survey of DDOS Attacks and Solutions using Packet Filtering Mechanism

Distributed Denial Of Service attack is the most significant and continuous threat in cyber security. It is one of the biggest security concerns for security professionals and has taken the attention of today's cyber world. This attack is an attempt by an attacker to flood the victim machine by generating a large volume of traffic using compromised machines. DDOS attacks can affect any device on any network and at the same time target different types of resources such as CPU, memory, and bandwidth, etc. The Decentralized nature of the internet helped the attacker to lunch this type of attack. The impact of a DDOS attack is huge like Money, time, clients and even reputation of the organization can be lost. Depending on the severity of an attack, resources could be offline for 24 hours, multiple days, or even a week. To prevent this attack, it is very important to filter the attack traffic not to enter the network. All filtering techniques are applied to the routers which ensure that only legitimate traffic can get access to a system. In this paper, we provide an overview of different types of DDOS attacks. we also cover different packet filtering techniques found in the literature along with their success and failure in DDOS prevention.
