FAQ About Understanding the Basics of Cybersecurity

What is a Denial-of-Service (DoS) attack?

A Denial-of-Service (DoS) attack is a type of cyberattack in which an attacker attempts to disrupt the normal functioning of a system, network, or website by overwhelming it with a flood of traffic, requests, or data. The goal of a DoS attack is to make the system or network unavailable to its intended users, causing a denial of service.

DoS attacks can take many forms, including flooding a network with traffic from multiple sources (a Distributed Denial-of-Service or DDoS attack), exploiting vulnerabilities in software or hardware, or sending malformed packets or requests that cause the system to crash or become unresponsive.

DoS attacks can have significant consequences for organizations, including loss of revenue, reputational damage, and disruption of critical services. Protecting against DoS attacks requires a combination of prevention and response measures. Prevention measures include implementing firewalls and intrusion detection systems, patching known vulnerabilities, and monitoring network traffic for signs of DoS activity. Response measures include identifying and isolating affected systems, filtering malicious traffic, and working with Internet Service Providers (ISPs) and law enforcement agencies to mitigate the attack.
