A 'friendly' denial of service (DoS) refers to a situation where service is disrupted due to unintentional actions, often by well-meaning individuals or systems that do not intend to harm. This could occur, for example, during a testing phase when a server inadvertently receives an overwhelming number of requests due to poor optimization or misconfiguration.

In contrast, a malicious DoS is deliberately executed with the intent to disrupt services, causing harm to an organization's operations, reputation, or other critical factors. This targeted attack can lead to significant financial loss and operational difficulties.

The nature of friendly DoS as unintentional is what sets it apart from malicious ones. While both types may result in service disruption, the motivations behind them and the contexts in which they occur are what distinguish the two. Additionally, the impact of a friendly DoS may vary based on the circumstances, but it is primarily characterized by the lack of harmful intent.
