Tunnel Use Advisory

This web page describes the rules and responsibilities for using the BNL Virtual Private Network to access resources within the BNL network via the Internet. Users MUST read this document and press the acceptance button below to be able to download the VPN client and all other VPN support files.

Virtual Private Networking allows a remote user to connect to the BNL network securely and access all the resources they would normally have at work including email by using one’s personal ISP account. This technology is a great advance in telecommuting but comes with stiff requirements. When connected, you are literally opening a secure tunnel through a network firewall. Therefore, it is your responsibility to guard this secure tunnel when connected to the BNL campus network.

For this reason, you must adhere to the following policies:

Maintain Your Antivirus Software

It is imperative that you routinely update your antivirus software (weekly, at a minimum). Many popular AV programs offer the ability to automatically check for updates. BNL offers Trend Micro Software, with automated updating.

Maintain Computer & Software Security Patches

Make sure you install the latest "Critical Updates" available for your computer's operating system, software, and hardware.

Microsoft Windows Update
Now you can get updates for Windows, Office and other Microsoft applications all in one place. Microsoft Update is a service that brings you all the features and benefits of Windows Update plus downloads for other Microsoft applications including Office.

In order to access the Cisco VPN AnyConnect download page and use Brookhaven Lab's VPN service, you must have DUO Two-factor Authentication already installed.

I have read and understand all the information stated above and I will comply. Press the button below to accept and proceed to the Cisco VPN AnyConnect download page.
