What is a DDOS?
A DDOS ("Distributed Denial of Service") is a malicious attack to disrupt the normal functioning of a computer network, service, or website by overwhelming it with a flood of traffic from multiple devices. DDoS attacks are often used to make websites and services inaccessible, particularly those relying on wrongly protected or slow server hardware.
How does it work?
To understand how a DDoS attack operates, consider the typical process of accessing an internet website. Visitors send requests to the website's server, which then responds. In the case of a DDoS attack, the server becomes the victim of a flood of requests, sometimes reaching millions per second. This incoming traffic overwhelms the server's capacity to respond, ultimately causing the service to become unavailable to legitimate users.
How to Identify a DDoS Attack?
Server Performance Degradation: If your website or online services experience a sudden slowdown or become inaccessible, it could indicate a DDoS attack is in progress.
How to Protect Yourself from a DDoS Attack:
Firewalls and IDS/IPS: For a proactive defense against DDoS attacks, it's wise to make use of firewalls and intrusion detection/prevention systems (IDS/IPS). These security tools can help identify and block suspicious traffic before it reaches your network, offering an extra line of defense against DDoS threats.
