Abstract: The study examines the growing threat of DoS/DDoS attacks against hotel computer networks, which are highly dependent on uninterrupted access to reservation systems, payments and internet services for guests. The aim is to propose an effective, multi-layered approach to prevent, detect and mitigate these attacks. Hotel networks are vulnerable due to their public nature (for example guest Wi-Fi) and limited IT resources. DoS attacks can block critical services, resulting in the inability to process reservations, payments and accommodation, causing not only financial losses but also a lot of reputational damage. Traditional defense mechanisms (simple firewalls) are often insufficient against today's high-volume DDoS attacks. An integrated approach based on several key methods is proposed. Successful protection requires a combination of on-premises network measures and powerful open-source tools. Hotels should accept the DoS threat as an operational risk and implement proactive, scalable solutions to ensure the continuity of their critical services and maintain customer trust.
