What is a DDoS Proxy Service?

The purpose of the on proxy service is to protect against cyber attacks from the Internet. Cyber attacks are those that can take down or deny an individual's access to information on the Internet. There are many types of cyber attacks and they can come in any form or fashion. The main goal is to prevent any type of attack from degrading a computer system. Some of these cyber attacks include Denial of Service attacks and Spyware attacks.

 

A denial of service attack occurs when a cyber attacker sends fake traffic to a target computer system and the target system responds by blocking the traffic. This is usually a temporary situation. In order to avoid this type of attack, it is important to prevent the packets of data that are sent through the proxy server. The answer to this question lies in the DNS filtering function.

 

When a DNS server is used for filtering, it can be configured to block or allow certain types of packets. These packets can include ICMP echo requests, ICMP Echo reply messages and ICMP Ping messages. When the mitigation is applied to the Echo requests, the server will reply with an ICMP Echo reply message rather than a normal ICMP packet. This is used for monitoring purposes. A regular ICMP Ping message will be replied with an ICMP Echo request instead.

 

The second type of cyber attack that is commonly used against reverse proxy servers is the spyware attacks. When the DNS filtering function of the reverse proxy service is used, it can be configured to block any packets that are sent to IP addresses that are previously blocked. If the attack happens to be successful, it can be possible to have the attacker's IP address banned from using the Internet for communication purposes.

 

Most of these common types of attacks require modifications to the websites that are being used for Ddos attacks. For example, a DDoS attack can be prevented if the website security measures such as an expiring content block are used. It should also be noted that most of these security measures will need to be implemented each time the reverse proxy server is activated. Apart from this, other website protection techniques that can be used for defense against Ddos include generating traffic to a site from an IP address that is not used for communication on the Internet.

 

When a mitigation for a cyber attack such as a DDoS comes into effect, the attack can be stopped if the attacker's IP address is banned from using the Internet for communication purposes. Another type of mitigation that can be applied for a cyber attack is the content filtering device. This device is typically used to block traffic that is not allowed on the Internet. Some examples of content filters include content-based IP filtering, proxy-aware filtering and DNS responder filtering. In order to allow traffic that is not supposed to go to a particular site to go to that site, a Ddos proxy Service will need to use a different method of IP address assignment.

 

If a cyber attack is very sophisticated, it may not only require the execution of many different methods of defense, it may also require the usage of IP spoofing. In simple words, a cyber attacker can use his own IP address to access a website. There are several ways in which an IP spoofing attack can occur including the installation of a key logger or screen capturing software. While some of the methods of the web application and website protection may not be possible with some applications, others like the use of a proxy server that uses a WAN IP address will offer some level of protection against cyber attacks.

 

An example of a method that IP spoofing can be used against is the use of a reverse proxy. A reverse proxy server will forward all requests to another IP address on the Internet, which will return the requested information to the client. For example, if the requested information is a link to a social networking site, the attacker can use his own IP address to access the social networking site. This is why a good DNS proxy service will make sure that the IP addresses of the DNS servers used by the customers are not used by anyone else to access any data.
