Mecanismo de acesso remoto para redes privadas utilizando túnel SSH reverso

Abstract

The increase in remote work and the growing need for secure access to private networks have brought new challenges for connectivity in corporate environments. Conventional remote access tools, while functional, face limitations in scenarios where high levels of security and efficiency are required, especially in environments protected by firewalls and CGNAT (Carrier-Grade Network Address Translation). This work proposes a remote access mechanism using reverse SSH tunneling, integrating communication through a server broker. The proposal aims to facilitate the management of remote connections by allowing dynamic control of access credentials, enhancing the security and reliability of connections. The methodology included the analysis of existing solutions, system architecture development, and validation in a real test environment. The results showed that the mechanism can overcome network restrictions, ensuring continuous and secure access without compromising data integrity. This method enhances digital security by providing a tailored solution for secure remote access in corporate settings, expanding connectivity options within protected networks, and improving the security and efficiency of remote operations.
