Description: Denial of authentication is a type of cyber attack that prevents a legitimate user from authenticating to a system, which can result in loss of access to critical resources. This attack can be carried out in various ways, such as overwhelming an authentication server, manipulating credentials, or exploiting vulnerabilities in authentication software. The main characteristics of denial of authentication include its ability to affect system availability, its impact on user trust, and its potential to be used as an attack vector in combination with other techniques, such as denial of service (DoS). The relevance of this type of attack lies in its potential to disrupt business operations, affect an organization’s reputation, and compromise data security. In an environment where authentication is fundamental to security, denial of authentication represents a significant threat that requires appropriate attention and mitigation measures.
