Posture Assessment of Systems Entering SLAC VPN
- What is changing and why?
As an open laboratory, SLAC makes every effort to enable access to tools and systems needed for research purposes without compromising the security and integrity of our other information and systems. The security of the SLAC network, however, must be protected from the risk posed by the number and variety of devices that use it. Consequently, effective March 19, 2018, devices being used to log into the SLAC virtual private network (VPN) will be checked to ensure they do not pose a security risk to SLAC.
- What’s the impact?
If you use a SLAC-owned, centrally managed device to connect to VPN, you will most likely be granted access with no issues. If your SLAC-owned device is denied access, contact the IT Service Desk (see contact info below) for assistance.
If you use a personally owned device, and that device meets the minimum requirements for using the VPN, then you will be allowed in. If, however, your device does not meet the requirements for OS version, virus control, and other security measures, you will be denied access to the VPN. You are responsible for updating your personally owned device.
If you use a device provided by an institution other than SLAC or Stanford, contact that institution for assistance.
If you are denied access, the following options are available:
- Update the device software so that it is compliant (see Minimum System Requirements below).
- Use Citrix as an alternative method for gaining access to the SLAC systems you need. To request Citrix access, in Service Now, go to the Service Catalog, then select Accounts & Access > Citrix Account Request.
- If you are using a personal or other non-SLAC-owned device, use a SLAC-owned, centrally managed device instead.
- If the device is SLAC-owned, contact the IT Service Desk (see contact info below).
- Minimum System Requirements
The minimum requirements are:
- Antivirus with current signatures (<15 days old)
- A current OS version, such as:
- Windows 10
- macOS 10.11 and up
- Android 10 and up
- iOS 13 and up
- Specific Linux versions are being confirmed and will be updated here when available.
- Resources
If you are a SLAC employee and need antivirus software for your home computer, free software provided by SLAC can be downloaded from the Cyber Security Resources page.
