What Is Denial of Service Attacks?

Denial service attack (DoS):

DoS is the kind of cybersecurity attack in which the malicious actor goals to exhibit the computer or other unavailable devices to its planned users by disrupting the normal functioning of the device. It is the scheme to overburden the machine or the network to make it unavailable. In the service denial of use attack, a single computer is the origin of the attack. Daniel’s service of the attack sends more traffic to the target making it unavailable service to normal users. The target examples include websites, online banking, email, or any other service that depends on the target computer or network.

Different types:

There are various types of the denial service of attack like as,

• Flood attacks
• Resource exhaustion

Flood attacks:

In a flood attack, DoS send the extended or maximum number of packets that surpass the capacity of the server. In a flood attack, a malicious actor can overfill the capacity. Most the denial service of flood attack is successful because the malicious actor has more bandwidth in comparison to the target.

Resource exhaustion:

In resource exhaustion, it targets the framework to utilize all the storage and memory, which results in slow performance or might be possible to stop all the functions together in the device. It is also called buffer overflow in which a machine uses all the storage available in the CPU, memory, and hard disk space. It results in system crashes and inactive behavior.

Distributed denial service of attack (DDoS):

DDoS is the type of denial service of attack it comes from various distributed sources such as botnet DDoS attacks. In this type of attack, the traffic is used to come from different distributed sources to overwhelm the target. By blocking the traffic source, it will not stop the attack.
