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 of the service. The mail servers, DNS servers and the servers which host the high-profile websites are that main target of DDOS attacks. Customers who use services of any shared network are also affected by this. Therefore, the anti-DDOS appliances are now extremely vital.
F.A.Q about DDoS Protection - Appliance
DDOS mitigation solution
There are two types of DDOS mitigation appliance. These include software and hardware. Identical functions may be claimed both forms of DDOS protection solution.
- Firewall is the most common protection appliance which can deny protocols, IP addresses or ports. However, they are not enough strong for provide protection from the more complicated DDOS attacks.
- Switches are also effective solutions for preventing the DDOS attacks. Most of these switches possess capability of rate limiting 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, the routers also have rate limiting and ACL capability. Most routers are capable of moving under the DOS attacks.
- Intrusion prevention system is 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 the DDOS attacks and stop them because they possess the granularity as well as process power required for understanding the attacks. Then they work in an automated manner.
- There are also the 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 the solutions of DDOS protection. 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 can be upgraded according to your requirements. These are some important factors that you need to consider while choosing an appliance of DDOS mitigation for your system.
