A Distributed Denial of Service (DDOS) attack is a type of cyberattack in which multiple computers, often compromised by malware or through the use of a botnet, flood a target website or online service with so much traffic that it is unable to handle it and becomes unavailable to legitimate users.
DDOS protection is a set of techniques or technologies that can be used to defend against these types of attacks. Some common methods include:
- Traffic filtering: This involves identifying and blocking traffic that appears to be part of a DDOS attack, while allowing legitimate traffic to pass through. This can be done using firewalls, intrusion detection and prevention systems, and other security devices.
- Traffic shaping: This involves limiting the amount of traffic that a website or service can receive, in order to prevent it from being overwhelmed. This can be done by limiting the number of connections from a single IP address, for example.
- Cloud-based protection: This involves using a service provided by a third-party company that specializes in DDOS protection. The service will divert traffic away from the targeted website or service and filter it to block any malicious traffic, while still allowing legitimate traffic to pass through.
- Scrubbing centers: These centers help to mitigates the attack by analyse traffic and clear the malicious one, this way only the legitimate traffic is reach the final destination.
DDOS protection is an important aspect of cyber security and can help to ensure that websites and online services remain available and accessible to legitimate users, even in the face of a DDOS attack.
