DDoS Mitigation Techniques Best Practices
In our last article we talked about some of the most well known Distributed Denial of Service breaches, and how they affected major organizations. In this lesson we will talk about some DDoS Mitigation Techniques that you can take away from so you can better prepare yourself in case you ever face this type of intrusion.
Just to recap on what a Distributed Denial of Service attack is for our newbies who missed out on our last article, I will briefly explain again on what this type of attack is.
Distributed Denial of Service attacks also know as a DDoS attack in its acronym form, is an attack to deny service to a person or organization.
Denial of Service attacks usual are attacks that hackers use to shut down an online service by overloading the server with various types of requests from host computers. Basically to recap this simple explanation from our last blog post, it is causing a website to shut down service so it loses money, or a good reputation from the public and its customers.
As we talked in-depth last time about this type of attack, and all the variations of it, we also talked about some of the most famous types of denial of service attacks too. If you missed out, then I suggest to go back and read it. We even added a super cool video for you to watch, which gives a very good explanation on how a denial of service attack is conducted!
How To Protect Yourself Against A DDoS Attempt, Technique 1:
So before we get into reading some DDoS mitigation techniques, we found a good YouTube video for you to watch and learn from. It’s a basic video and offers one of the many denial of service attack solutions that we will be discussing in this article.
Know Your Attacks! Technique 2:
First thing is first, you have to know what an attack looks like, and know when and how to act. If you notice that your website is down for strange reasons, then you should start to trouble shoot your network and keep it in the back of your mind that your website could be under attack.
If you are unable to access any type of website from you companies network, or you are receiving a drastic increase in spam emails to your organizations email addresses, then your server is being overloaded with requests which could be a breach.
Also if you notice that your network is moving painfully slow, and it’s not just because there are tons of users on at the same time, there are no major internet outages in the area, and all your computers are up to date with the most current patches and firmware updates, then suspect a hacker attack against your business.
Dynamic Filtering, Technique 3:
You can use dynamic filtrating to weed out the number of request your server is receiving. By filtering out the requests, you can identify and rule out the unusual behavior that your network is receiving.
This odd behavior can be altered for a short period of time by making a span filtering rule and removing that rule once the hacking attack is over.
This protection method is used when the Denial of Service attacks are smart enough to change their tactics at a fast pace. This type of filtering is used through an Access Control List (ACL) that your companies IT administrator should have knowledge of, and access to.
White & Black Listing, Technique 4:
This is a very easy to perform and useful technique due to its simplicity. Regardless whether you are on a home and personal network, or are apart of a large company infrastructure, you have some options to stop a DDoS breach.
You can always block IP addresses from entering into your current network. You have the ability to deny or allow traffic from a specific sender from reaching your server. With the White and Black listing rules that you can set up, you can stop DDoS attacks because they will never have the opportunity to reach your computers and overload them, making this a very useful technique.
Use Third Party Software, Technique 5:
We will give you one more of our DDoS mitigation techniques suggestion. You could always just download software at a fair price that could make the whole protection thing a whole lot easier. Some of the best products keep you from haveing to do any of the configuration stuff yourself if you are unfamiliar with how to do it.
Here is some third party software that is capable of stopping SYN, TCP, UDP, ICMP floods, and bandwidth attacks.
BeeThink’s product is also capable of stopping slow HTTP attacks, and has the ability to block country IP addresses without you touching any sort of complex controls, or knowing how to write rule signatures.
This DDoS mitigation software can do some other stuff too, so check out the features it can perform on their website.
That’s all were going to throw at you for now on how to stop a Denial of Service attack. Please give us your thoughts and experiences on this subject matter. Has your cyber security company or organization ever been hit with a DDoS attack? Let us know with you comments below?
