DDoS attack
What is DDoS attack?
DDoS is short for Distributed Denial of Service. DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.
The different between DoS & DDoS?
The difference between a DoS and DDoS attack is quite simple. A DoS attack usually targets a victim at the application layer, with the same intentions of rendering a website unusable. A DoS attack is accomplished by a single user using a single internet connection.
How the attack works?
In a DDoS attack, the incoming traffic flooding the victim originates from many different sources – potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.How to mitigate the DDoS attack?
There are a few ways to help protect yourself against DDoS attacks.
- Keep an eye on the inbound traffic hitting your server. The sooner you see an unusual spike in traffic that looks suspicious, the sooner you can start investigating.
- Add filters to your router to drop packets from suspicious sources
- Implement rate limiting in the event you are being attacked in order to avoid your server being overwhelmed.
- Use a DDoS protection service
