Basic Tips To Prevent A DDoS Attack
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 isthat 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 preventDDoS
attack, let’s first understand what exactly a DDoS attack is!
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 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
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.
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.
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.
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.
