4 Tips on How to Mitigate DDOS Attack
Published on: December 4, 2013 by Mike

DDOS, which is an acronym for Distributed Denial of Service, are the attacks that can result in heavy business loss. They turn out to be very expensive for any business if considered in terms of lost revenue and added expenditure on the recovery and protection. A major question, how to stop ddos attacks can be answered through various means such as firewalls, switches and other sorts of intrusion analyzing programs.

What is DDOS Protection and Is It Possible?

A ddos attack can never be fought without employing and using high-end and secure internet channels, specialized and dedicated software solutions and hardware equipments. Hence, fighting against ddos attacks become little difficult for small scale businesses. In order to learn how to protect against ddos and their new generation attacks, it is important that the users adopt and follow the new mitigation techniques. These techniques would be effective irrespective of the type of attack. The knowledge of these techniques would definitely help the users to protect their servers and aid their systems.

Tips on How to Defend Against DDOS Attacks

The Firewall

Few simple protocols can be used by the network administrators to restrict IPs and ports. Depending on the firewall’s location in the network, the firewalls can be very effective in preventing flooding attacks. However, they are not efficient and intelligent in determining good traffic. The complex attacks are hard to prevent as it is not possible to drop and accumulate the traffic to one particular port as it might prevent the needed traffic to reach the server. The deep in the network firewalls are not as helpful as they should be because the routers get clogged even before the traffic reaches firewall. However, they prove to be efficient to prevent the minor DDOS attacks.

Switch Can Be Used As a Mitigation Tool 

Switches are generally designed with an automatic control list capacity. Hence, they have the ability to limit the data floods, shape the traffic, delayed binding and even bogon filtering. The traffic rate limiting here is possible because the traffic shaping delays some or complete data in the process of bringing them into the desired and required traffic profile. This can efficiently be used to increase the bandwidth of particular traffic by compromising bandwidth for others.

The Router

The rate limiting capacity of a router can be manually set by the network engineers and hence, a control list can be configured. And as a result, the routers can prevent the requests from ddos attack and this can keep the network safe and working to its users.

Sink and Black Holing

The technique of sending traffic to a particular IP that works so as to confirm that it receives the incoming traffic and filters it to prevent the bad traffic is referred to sink holing. Whereas, the technique of sending the incoming traffic to a nonexistent IP address is referred to as black holing.
