IS&T SNU enforces a policy of blocking websites to ensure an appropriate Internet environment for education, learning, and research for the SNU community. 

When a user connects to a website or runs a client for a specific service, if the website or service is included in the database of harmful Internet information , that website or service will automatically be blocked. 

The user will be redirected to a separate blocking notification page, and the service client will display an error message, such as “Connection Failed” or “Not for Use.” The present policy is to block games, stock exchanges, gambling sites, P2P capabilities, and web hard disk. If requested by a user, a decision will be made on whether to lift the block after review (only for educational and research purposes).
