Network security threats come in various forms, targeting the integrity, confidentiality, and availability of network resources. Below is an overview of common attacks, their mechanisms, and their potential impact.
1. Denial-of-Service (DoS) / Distributed Denial-of-Service (DDoS)
Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks are malicious attempts to disrupt the normal operation of a network, service, or system by overwhelming it with traffic or resource requests. These attacks can cause significant financial and reputational damage to organizations.
1. Denial-of-Service (DoS)
Mechanism:
A DoS attack targets a system or network by overwhelming it with a massive number of requests or data packets. This exhausts the target's resources, such as CPU, memory, or bandwidth, rendering it unable to process legitimate user requests.
