In order to fully stopping DDOS attacks, you need to understand the concepts behind it first. Denial of Service attacks or DDOS attacks are common in the internet. It is actually an attempt of several groups to make a computer source seem unavailable to several users and community members. It generally consists of concerted efforts from several individuals or multiple people to prevent a server or a website functioning. Usually, the attacks are designed to indefinitely or temporarily take down a site. Stopping Denial of Service attacks can be done through several techniques. Firewalls, switches, and other forms of Intrusion detection programs are primarily used to stopping DDOS attacks but in this day and age, they are ineffective when it comes to well planned intrusions. In order to stop the new generation of attacks, users would need to learn of new mitigation techniques. These techniques are still effective regardless of what type of attack occurs. By knowing these techniques, users would surely be able to protect their servers and by stopping DDOS attacks they would be able to aid their respective systems.
Take a look-DDoS protection
One of the most common ways in stopping Denial of Service attacks is through the use of active Verification. Active verification can be done through Legitimate IP address crossing and matching. It is necessary to identify cache and legitimate IPs through a memory bank for a limited period so that you would be able to detect which IP addresses are spoofed and which ones are legitimate. Once the checking is done, you can further protect and check on legitimate IP addresses by rate through limiting zombies which have the capabilities to complete three way handshakes. Usually, stopping DDOS attacks would be easy when using this technique since most attacks are written using various scripts which continuously vary from a few parameters from several network packets. Another way to stop the attacks would be to perform an anomaly check on headers as well as states and the rates of any device. Several applications can actually filter out the IP addresses and attack packets hence stopping DDOS attacks. By using simple firewall rules, such attacks would not be possible.

Protocol and Granular rate limiting are also excellent ways in stopping Denial of Service attacks. Similar to target headers and rate problems, further analysis of protocols in your computer as well as the analysis of the generic firewall should be done in order to control any form of attacks. Granular limiting can be done when attacks are unpredictable. It is actually a type of management technique wherein it identifies and checks rate violations from past records of IP addresses and behaviors coming from the system. Granular limiting is also a good way to stop DDOS attacks because it rates the set of protocols in your system by checking on the past behavior of the system in every session. You can do granular rate limiting techniques in your computer in order to control data. All of these tricks are effective DDOS-attacks and they can be done either manually or through the use of a software program.
