Alocação de recursos sem limite (negação de serviço por esgotamento)

A aplicação aloca recursos (memória, conexões, arquivos, threads) a pedido de um usuário sem impor limites, permitindo que um atacante esgote todos os recursos disponíveis e derrube o serviço. É basicamente deixar a porta aberta para qualquer um encher a caixa d'água até transbordar.

Exemplo

Um servidor web que cria uma nova thread para cada requisição HTTP recebida, sem limite. Um atacante envia milhares de requisições simultâneas e esgota o pool de threads, tornando o servidor inresponsivo para usuários legítimos — é negação de serviço puro.

Como mitigar

Implemente limites rigorosos: rate limiting (requisições por IP/usuário), quotas de recursos, pool de threads/conexões com tamanho máximo, timeout em operações, e monitoramento de consumo. Valide tamanhos de entrada e rejeite alocações que excedam os limites configurados.
