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.
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.
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.
