Understanding DDOS Attack
A DDoS (distributed denial-of-service) attack is an attempt made by  attackers to make computers’ resources inaccessible to its anticipated  user. In order to carry out a DDOS attack the attackers never uses their  own system; rather they create a network of zombie computers often  called as a “Botnet” – that is a hive of computers, to incapacitate a  website or a web server.
Let’s understand the basic idea! Now, the attacker notifies all the  computers present on the botnet to keep in touch with a particular site  or a web server, time and again. This increases traffic on the network  that causes in slowing down the speed of a site for the intended users.  Unfortunately, at times the traffic can be really high that could even  lead to shutting a site completely.
3 Basic Tips to Prevent a DDoS AttackThere are several ways to prevent the DDOS attack; however, here in this guest post I’ll be covering three basic tips that will help you to protect your website from the DDoS attack.
1. Buy More Bandwidth.
One of the easiest methods is to ensure that you have sufficient  bandwidth on your web. You’ll be able to tackle lots of low-scale DDOS  attacks simply by buying more bandwidth so as to service the requests.  How does it help? Well, distributed denial of service is a nothing more than a game of capacity. Let’s suppose you have  10,000 computer systems each distributing 1 Mbps directed towards your  way. This means you’re getting 10 GB of data that is hitting your web  server every second. Now, that’s causes a lot of traffic!
So to avoid such issue, you need to apply the same rule intended for  normal redundancy. According to this technique, if you wish to have more  web servers just multiply around diverse datacenters and next make use  of load balancing. By spreading your traffic to various servers will  help you balance the load and will most likely create large space  adequate to handle the incessant increase in traffic.
However, there’s a problem with this method that is buying more  bandwidth can be a costly affair. And as you’ll know that the current  DDoS attacks are getting large, and can be a lot bigger exceeding your  budget limit.
2. Opt for DDoS Mitigation Services.
A lot of network or Internet-service providers render DDoS mitigation  capabilities. Look for an internet service provider having the largest  DDoS protection and mitigation network, automated tools, and a pool of  talented anti-DDoS technicians with the wherewithal to take action in real-time as per the varying DDoS attack characteristics. A  viable alternative is to utilize a DDoS prevention appliance, which is  specifically intended to discover and prevent distributed  denial-of-service attacks.
3. Restricted Connectivity.
In case you have computer systems that are connected to the web  directly, a better idea is to properly install/configure your routers  and firewall so as to limit the connectivity. For an instance, while  receiving some data from a client machine you can only allow traffic to  pass from the machine only on a few chosen ports (like HTTP, POP, SMTP  etc.) via the firewall.
Wrapping Up!Websites are largely getting attacked by hackers every second.  Denial-of-service attack is insanely getting huge and is creating a lot  of problems for business organizations having strong online vicinity. In  this guest post you’ll not only understand what a DDoS attack actually  means, but will also come to know about a few type of methods to prevent DDoS attacks. Aforementioned are three  tips that I’ll recommend you to run through to at least understand where  to get started towards building a resilient web network with chances of  surviving a DDoS attack.
