Melhorando a segurança de sistemas baseados no protocolo SNMP contra ataques de negação de serviço (DOS)

Abstract

The current corporate context includes information security indices that, if treated inappropriately, can result in severe impacts, which can affect the finances or security of companies. The data grows exponentially in quantity and complexity, possibilities tend to reflect that a reactive posture is no longer sufficient. In contemporary society, information is considered an organization's main assets, and it is also under constant risk. Their loss or theft can be a loss for an organization. Information is an asset that does not suffer depreciation. It has a constant appreciation, both in the development of our business and in the maintenance of current ones. This article tests how a system based on the SNMP protocol (Nagios) behaves when suffering a denial-of-service attack. All network processes are monitored in real time, to prevent and prevent means to computers. The technique used for UDP FLOOD. Then, the solution to the problem is presented when there are large packages of packages for a given device, slow leakage or unavailable. Finally, it is believed that there are tools available to improve the security of systems that monitor the network.
