What a Horror Film Teaches About Hidden Risks in Campus Network Security

The film "The Call of Terror" tells the story of a well‑secured villa by a lake where a part‑time nanny receives disturbing phone calls; the police discover the caller is already inside the villa because the garage door was left open, allowing the killer to enter.

In the same way, a campus internal network is split into a database zone and an APP zone. The database zone, like the villa’s main door, is tightly protected and only serves the APP zone. The APP zone, comparable to the garage, has looser controls because it must communicate with the external network, creating a vulnerable entry point for attackers who first compromise an externally facing APP server and then pivot to the database server.

To counter this, eSDK provides an open controller security‑policy interface that can block the attacker’s path to the APP server. The TSOC security platform from Venustech analyzes security logs and correlates low‑risk events to detect data‑theft attempts; once malicious activity is identified, TSOC automatically invokes the security‑policy interface to restrict the offending endpoint or block the source IP from accessing the APP zone, preventing internal breaches and data leakage.

The case study ends with a preview of next week’s example: how eSDK helps Huayu build a mobile court system for the Beijing High People’s Court, and a discussion of BYOD security.
