What characterizes an adverse event in network security?

An adverse event in network security is characterized by a negative impact on a system or network. This definition encompasses various incidents that can compromise the integrity, confidentiality, or availability of network resources. Adverse events typically include security breaches, data loss, or disruptions in service that can lead to financial losses, damage to reputation, and a decrease in trust from users.

While unauthorized access is also a relevant concern in network security, it is a specific type of event that could lead to an adverse outcome, rather than defining what constitutes an adverse event itself. An increase in performance and successful data retrieval are generally positive outcomes and do not align with the concept of an adverse event, as they imply that the system or network is functioning optimally rather than experiencing a detrimental incident.
