8 Tactics to Protect Against DDoS Attacks In 2021   

What is Distributed Denial-of-Service (DDoS) Attack

A DDoS attack is a type of cyber-attack that involves an attempt to make a machine or system unavailable by overwhelming it with amounts of data. The data being sent to the machine is overwhelming the bandwidth and resource availability and in turn, is making the machine inaccessible or unusable.  

Even in a world where a hacker seems to be at every corner, with millions of users going online every day, it is possible to protect against DDoS attacks in 2021.

From switching up your DNS to using bots to scan for vulnerabilities, it is important to be aware of the risks and take preventative measures.

Here are a few tactics to keep you safe from DDoS attacks in the year 2021. 

Tactics to Keep You Safe from DDoS attacks in 2021

  1. Enable Domain Name System Firewalls

For those who have been around the web for a while, you’ll know that many use a domain name system.

This helps connect and regulate the traffic and data that gets sent and received over the web.

This is usually comprised of a server, which can be located in any country across the globe. With this comes risks as hackers now know how to access your servers and use them for illegal activities like DDoS attacks. 

Whether it’s provided by your ISP or by your host provider, these are the machines that make sure your website is working. 

The issue with this is that hackers can spoof domain names, meaning they can take over the system and make it act as if they are the server hosting the site instead of you. 

  1. Monitor the traffic at your edge 

An article published by Akamai Technologies, on May 5, 2019, talks about how the intensity of DDoS attacks are on the rise with the number of new attacks jumping from an average of 550 per week in Q3 2018 to more than 1,000 attacks per week in Q1 2019.

They argue that the increase in attacks will continue to be sustained in 2021. To protect against this, Akamai recommends getting a cyber security plan in place and monitoring the traffic at your edge. 

  1. Filter malicious packets with packet inspection 

Digital disruption can be prevented with simple measures such as implementing a firewall with protocol inspection that will filter malicious packets.

Additionally, companies should establish a cyber security plan that includes identifying staff with the most critical access permissions, regularly testing their security systems, and conducting a vulnerability assessment. 

  1. Double up your cyber security protections 

Educate your employees on the potential risks -Build a healthy workplace culture -Increase your Cyber Insurance coverage -Prepare your company for a data breach by creating an incident response plan -Use secure vendor management to protect against compromised code 

  1. Introduce protection to third-party services that are linked to the website 

A DDoS attack is when one or more computers send data to a server or service in order to disable or disrupt it. The attacks are often conducted by botnets, which are systems infected with malware that perform the actions of the attacker.

Over the years, DDoS attacks have become more powerful, making it easier for hackers to paralyze systems and bring websites down. But there are ways to protect against these attacks. 

  1. Avoid rapid variations in load times 

Even though there will be many changes in the future, it is important to implement anti-DDOS measures to protect against disruptions. One way to do this is by implementing a content delivery network (CDN).

A CDN works to distribute content across servers, which will decrease the time it takes for the server to load. 

  1. Deploy more geographically dispersed servers 

Multiple servers will need to be deployed in different geographical locations in order to not be susceptible to a distributed denial-of service attack.

Since the attack is relying on human error, it is hard to prevent. Therefore, having servers spread across different regions will make it harder for the attacker to do what they want to do. 

  1. Ensure that firewalls are enabled and set up properly

Firewalls will need to be set up in order to prevent an attacker from being able to easily bypass them. 


Technology gives equal opportunity to everyone to reap maximum benefits. Hackers are becoming very smart using this technology. They innovate multiple ways to launch a cyberattack and halt the functionality of a system. So, It has become a need of the hour to shield your organization with an advanced defensive mechanism.

FAQS related to DDoS attacks in 2021

What is a DDoS attack example?

A DDoS attack is a planned cyber attack that malfunctions the performance of a system. It sends multiple requests to under attack web resources aiming to exceed website capacity to handle these multiple requests.
e.g. DNS amplification, SYN Flooding, and UDP Flooding

Is DDoS attacking Illegal?

It is illegal without any doubt in almost all corners of the world. It is considered a cybercrime in the USA particularly. Computer Fraud and Abuse Act (CFAA) treats it as Federal Criminal Offense.

What is a DDoS in Simple Terms?

It is a cyber attack on a service, website, or server. It can also flood the network with massive internet traffic. Successful attack renders network, website, or service malfunction.

How Do You know If You are getting DDosed?

There are several ways to get information that you are being attacked. The first and foremost clue is that your IP address makes X requests over Y seconds. Service starts responding 503 due to service outages.

How long do DDos attacks Last?

DDoS attacks are very severe most of the time yet they vary in their time span. They are comprised of a time span of up to 24 hours.

Can a VPN protect you from DDoS?

VPN with a hidden IP address is a good shield to protect you from DDoS attacks. Generally speaking, VPN makes it difficult to get your network located. In addition to that VPNs encrypt web traffic. It can hide activity from internet service providers while creating a tunnel between network and computer.
