DDOS, or Distributed Denial of Service, is a type of cyber attack that is designed to make a website, online service, or network unavailable to users. The attack works by overwhelming the target with a large amount of traffic from multiple sources, making it impossible for the target to handle the volume of traffic and causing it to crash or become unavailable.
In a DDOS attack, the attacker uses a network of compromised computers, known as “bots” or “zombies,” to send a huge volume of requests to the target. The requests can come from multiple sources, making it difficult to block the attack and making it appear as though the traffic is coming from legitimate users.
The goal of a DDOS attack is to disrupt the normal functioning of a website or online service, making it unavailable to users. This can have serious consequences for businesses, causing loss of revenue, damage to reputation, and other negative impacts.
There are several different types of DDOS attacks, including:
Volume-based attacks: These attacks involve sending a large volume of traffic to the target, overwhelming its network and making it unavailable.
Protocol attacks: These attacks exploit weaknesses in the protocols used by a website or online service, causing the target to become unavailable.
Application-layer attacks: These attacks target specific applications or services, such as a web server or database, and are designed to exhaust their resources and cause them to crash.
Preventing DDOS attacks is a complex and ongoing process that requires a multi-layered approach. This can include implementing network security measures, such as firewalls and intrusion detection systems, as well as utilizing content delivery networks (CDNs) and other mitigation technologies.
In short, DDOS attacks are a serious threat to the stability and availability of websites and online services, and organizations need to take steps to protect themselves and their users from these types of attacks.
