DDoS Protection - Appliance

A denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.

In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. This effectively makes it impossible to stop the attack simply by blocking a single source.

A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, disrupting trade.

Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge, blackmail and activism can motivate these attacks.

Buying a DDoS mitigation appliance can be highly confusing, especially if you have never done this before. While selecting a DDoS protection solution you must understand the right features and have proper background knowledge. In case of distributed denial of service attacks, the bandwidth or resources of any targeted network is flooded with a large amount of malicious traffic. As a result, the system becomes overloaded and crashes. The legitimate users of the network are denied the service. The mail servers, DNS servers and the servers which host high-profile websites are the main target of DDOS attacks. Customers who use services of any shared network are also affected by these attacks. Therefore, anti-DDOS appliances are now vital.

F.A.Q. about DDoS Protection - Appliance

DDoS mitigation solution

There are two types of DDoS mitigation appliances. These include software and hardware solutions. Identical functions may be claimed by both forms of DDoS protection.

  • Firewalls are the most common protection appliance, which can deny protocols, IP addresses or ports. However, they are not enough strong to provide protection from the more complicated DDoS attacks.
  • Switches are also effective solutions for preventing DDoS attacks. Most of these switches possess rate limiting capability and ACL. Some switches provide packet inspection, traffic shaping, delayed binding and rate limiting. They can detect the fake traffic through balancing and rate filtering.
  • Like switches, routers also have rate limiting and ACL capability. Most routers are capable of moving under DoS attacks.
  • Intrusion prevention systems are another option for you when it comes to protection from DDoS attacks. This solution can be effective in several cases of DDoS attacks. It can identify DDoS attacks and stop them because they possess the granularity as well as processing power required for identifying the attacks. Then they work in an automated manner to resolve the situation.
  • There are also rate-based intrusion prevention mechanisms, which are capable of analyzing traffic granularity. This system can also monitor the pattern of traffic.

You must check the connectivity while selecting a DDoS mitigation appliance. Capacity is also an important aspect of a DDoS protection solutions. You must figure out the number of ports, IPs, protocols, hosts, URLs and user agents that can be monitored by the appliance. An effective DDoS mitigation solution must also be properly customizable. Your DDoS mitigation appliance should be such that it can be upgraded according to your requirements. These are some important factors that you need to consider while choosing a DDoS mitigation appliance for your system.
