In recent years, with the popularization of the remote-working mode, using intranet penetration tools has gradually become a convenient and efficient solution. However, it is imperative to recognize its potential threats.

First, intranet penetration does indeed entail certain risks. Allowing external users to access and connect to internal resources may increase potential security threats. Here are some potential risks:

1. Unauthorized access: Intranet penetration allows unauthorized users to access internal resources. Without proper access control and authentication mechanisms, attackers may exploit this vulnerability to access the intranet.

2. Exposure of sensitive data: Intranet penetration may lead to the exposure of sensitive data. Without proper encryption measures, external users may be able to intercept and steal sensitive data during data transmission, causing harm to organizations or individuals.

3. Denial-of-service (DoS) attacks: The device using intranet penetration service may become the target of attack. If attackers can discover and exploit vulnerabilities in intranet penetration services, they may launch DoS attacks, rendering internal resources unavailable.

Common intranet penetration tools currently include Ngrok, FRP, SSH Tunnel, ZeroTier, etc.

To safeguard the information security of the University and internal members, it is NOT allowed to use intranet penetration tools to access internal resources. We provide the official VPN (Virtual Private Network) tool, which is an encrypted channel that ensures data security and integrity when internal users access the intranet outside the campus. With identity authentication and access control mechanisms, it is effective to protect internal resources against unauthorized access.
