What does DDoS attack stand for, and how can it affect us?

In today’s interconnected world, the security of digital platforms is more critical than ever. One of the most prevalent threats to this security is the Distributed Denial of Service (DDoS) attack. This post aims to explain what a DDoS attack is, how it functions, and the potential impacts it can have on individuals, businesses, and the internet at large.

What Does DDoS Stand For?

DDoS stands for Distributed Denial of Service. It is a type of cyber attack that aims to make a website or online service unavailable by overwhelming it with traffic from multiple sources. Unlike a Denial of Service (DoS) attack, which typically uses one computer and one internet connection to flood a target with fake requests, a DDoS attack comes from many compromised devices, often distributed globally. These devices are part of what is known as a botnet.

Why does DNS cache matter & How to flush it?

Data exchange happens at a lightning pace. Every time you type a website address into your browser, it doesn’t immediately connect you to the requested website. Instead, a series of behind-the-scenes processes take place, one of which involves DNS (Domain Name System) resolution. DNS acts like a directory, translating human-readable domain names into IP addresses that computers can understand. But what role does DNS cache play in this process, why does it matter, and how can you flush it when necessary?

What is DNS Cache?

DNS cache is a mechanism employed by computers and networking devices to store recently accessed DNS information locally. When you visit a website for the first time, your computer sends a request to a DNS resolver to translate the domain name into an IP address. Once the resolver obtains the IP address, it stores it in its cache for future use. Next visits to the same website skip the DNS resolution process and directly access the IP address from the cache, speeding up the browsing experience.
