Home / Cybersecurity / What is a DOS Attack Denial of Service
After a short period of decline in incidences, denial of service (DoS), and Distributed denial of service attacks (DDoS) have become rampant once more. Whenever there is a major internet security incident, it mostly means that a DDoS attack occurred. These cybercriminals often target websites, personal accounts, servers, and other services to overload its internet traffic until the victim’s system becomes impassive to legitimate requests.
Virtually every business organization and governmental agencies consistently need the services of ethical hackers to tackle the mounting threats to Cybersecurity. In the modern-day of IT security, Certified Ethical Hackers are invaluable, which is why they work alongside some of the best and largest organizations across industries such as ICT, financial, healthcare, energy, and government, among several others!
Ethical Hacking is a standard requirement for handling DDoS and DoS attacks. The Certified Ethical Hacker (C|EH) training and credentialing program is an esteemed and reliable Ethical Hacking program offered by EC-Council and teaches you everything you need to know about DoS attacks and how to conduct one ethically.
A denial-of-service attack or DoS attack is a type of cyber-attack that occurs when an attacker seeks to render a computer or other networks inaccessible to its authorized users by momentarily or permanently interrupting the normal operations of a host linked to the Internet. Simply put, a denial-of-service (DoS) attack occurs when a cybercriminal prevents an authorized user from retrieving their personal data or files.
Typically, in a DoS attack, a single or group of computers are used to launch an attack. When these attacks are launched, they negatively affect an extensive array of services, including online accounts, private data, emails, websites, and other platforms that depend on the compromised computer or network.
A denial of Service attack is often achieved using TCP and UDP packets. In a DoS attack, the perpetrators flood the user’s system with illegal traffic or service requests to inundate its resources and stop it from executing intended tasks.
A DoS attack can target distinct computers or a whole network system. These attacks can be costly for a company, both in terms of finance and timewise, until their services and other affected resources are restored or become accessible.
