Denial-of-Service Attacks

When cybercriminals or attackers flood the traffic on the server and not giving time to respond to the request, it is called Denial-of-Service attack. In this attack, it is hard to manage the servers because sometimes an attack can be done by number of systems at the same time from different locations which are called Distributed Denial-of-Service.



Types of DoS Attack


Distributed Denial-of-Service attack means number of systems simultaneously attacks a single target. By attacking hundreds of systems on the same target, the traffic will be increased to busy the website. To implement this attack, number of different systems is needed to target someone.

Network-Targeted DoS

In this attack, the attacker will flood the traffic by using the bandwidth of the network. In Transmission Control Protocol (TCP), the congestion control signals will not be esteemed by flooding packets on the network.

System-Targeted DoS

System-Targeted DoS attacks happen where limited resources of the system are in use such as Central Processing Unit (CPU). The user may face problem of system crash by slow it down or system disruption.

Application-Targeted DoS

This attack involves the application based Denial-of-Service attack which can lock the users’ accounts and they will not be able to enter their own account. Sometimes, it produces the error condition which tends to crash an application.

Solution to prevent DoS Attacks

Implement mitigation strategies

Different mitigation strategies can be implemented for different cyber attacks. However, Denial-of-Service attacks also a huge issue to resolve to secure the network. The strategy of plan and monitor the network security can be helpful to reduce the risk of getting attacked by cyber criminals.
