3 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 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!
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 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.
