Distributed denial-of-service (DDoS)
attacks are always in top headlines worldwide, as they are plaguing websites in
banks, and virtually of almost every organization having a prominent online
presence. The main cause behind the proliferation of DDoS attacks is that there
is a very low-cost that the attacker has to incur to put such attack in motion.
Fortunately, today various prevention methods have been developed to tackle
such attacks. Before delving further into understanding about the ways to
prevent DDoS attack, let’s first understand what exactly a DDoS attack is!
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 Attack
There 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.
There 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.
