Cybersecurity threats have become more complex with time, with several factors such as integrated networks, multiple hosts, and extensive IT infrastructures contributing to this issue. Distributed denial of service (DDoS) is one such appealing strategy regularly deployed by hackers.
With people relying more and more on online services, it is now critical to improve our network security. By the end of 2020, major companies like PUBG, Blizzard, and Bitcoin were all hit by DDoS attacks . The global pandemic has played a role in this increase because of less secure home environments . Attacks became more complex and targeted organizations across different industry verticals.
What is DDoS attacks?
Distributed denial of service attacks is a common cybersecurity threat that occur when a malicious hacker floods your network, service, or web server with traffic to interrupt its regular operations. DDoS threats are launched by flooding the target network or web server with fake packets, requests for connections, or messages.
The name distributed denial of service attack originates from the method of attack where illegitimate traffic comes from different sources. For instance, Amazon’s AWS Shield service abated the most powerful DDoS attack ever documented in February 2020, coming in at a whopping 2.3 Tbps (Terabit per second).
Why You Should Worry About DDoS Attacks
DDoS attacks have evolved over the years, becoming easier to launch and more ferocious than ever. This attack methodology targets organizations irrespective of their size. However, only a few organizations have the resources and know-how to address cybersecurity threats. Most experts believe that about 50 million attacks go undetected per year. The financial cost of such attacks can reach as high as USD 500 billion.
Not only do these losses affect business opportunities, revenue, and productivity, it also puts a dent in the reputation of an organization. In most scenarios, operational costs increase rapidly while organizations struggle to find and resolve their security weaknesses.
How to Prevent DDoS Attacks
Tools and automation are useful when you want to prevent cybersecurity threats and protect your IT assets. However, human intelligence and effort are required to protect your IT infrastructure to the maximum extent possible. You should also not ignore the role of certified ethical hackers ilities in the system.
Monitor Your Traffic
Get familiar with what represents the normal, high, or low volume of traffic for your enterprise. You need to know the current trends in your traffic to identify abnormalities quickly. When you know what to expect, you can implement rate-limiting, where the server will only accept what it can handle. Also, you should be ready for traffic surges based on marketing campaigns, seasonality, etc.
Develop a Denial-of-Service Response Plan
You can easily detect when you’re under a DDoS attack if you know how to differentiate it from normal traffic on your website. There is usually no time to take the necessary steps when a DDoS attack hits. So, set up a DoS plan based on a comprehensive security assessment. Having an incident response plan is a step towards defense-in-depth security strategies.
Practice Sound Cyber Hygiene
Not to sound too obvious, but you can’t have a good defense plan without equally good cyber practices. You need to promote a security-based corporate culture and ensure that all your IT teams adhere to industry best practices on cybersecurity.
Implement a CDN
A content delivery network or content distribution network is a geographically distributed platform of servers that reduces delays in loading web page content by minimizing the physical distance between the user and the server. The objective is to avoid overloading your hosting server.
The trick is to store your data on several servers across the globe. CDN implementation makes you less vulnerable to an attack since you have other options if one server becomes overloaded.
Hire an Ethical Hacker or VAPT Expert
Getting rid of cybersecurity threats is impossible if your organization doesn’t have an ethical hacker on hand. The resources and knowledge at the disposal of these professionals will help you counter DDoS attacks and any other problem that may plague your business’ operations.
The best way to approach this issue is to consider a professional who has trained through an ethical hacking course online and understands every essential practice to improve your organization’s cyber hygiene. Certified Ethical Hacker (CEH v11) trains cybersecurity professionals to understand every relevant attack tactic used by malicious hackers. The assistance of network defense and penetration testing professionals will also prove helpful in countering these issues. A 360-degree vulnerability assessment and penetration testing action plan will truly eliminate the dangers of these malicious attacks.
