How to prevent DDoS attacks?

Over the past year, there has been a significant surge in DDoS attacks, largely attributed to the global pandemic. With a vast number of individuals working remotely and relying heavily on online services through remote connections, the vulnerabilities in digital infrastructure became more apparent. As per the reports, around 10 million DDoS attacks happened against essential online services. The DDoS attacks wreaked havoc on e-commerce, healthcare, streaming services, and remote learning, disrupting business operations and extortion by hackers.

What is a DDoS attack?

A Distributed Denial-of-Service (DDoS) attack is a malicious attack intended to disrupt the regular traffic of a targeted network, service, or server by flooding the target or its surrounding infrastructure with Internet traffic. It involves multiple connected devices, known as botnets, used to flood target websites with malicious traffic.

How does a DDoS attack work?

DDoS attacks are worked with networks of Internet-connected machines. These networks include systems and other IoT devices infected with malware and controlled remotely by an attacker. The individual devices are known as bots, and a group of bots is called a botnet. If a botnet has been established, the attacker can attack by sending remote instructions to each bot.

When the botnet targets a victim’s network or server, each bot sends requests to the target’s IP address, which potentially causes the server or network to become infected, resulting in a DDoS to regular traffic. As each bot is a legitimate Internet device, splitting the attack traffic from regular traffic can be difficult.
