While new systems are being built and configured in this zone and before they are fully vetted by security, they are firewalled in a subzone.
Host Configuration Requirements:
These systems must:
Use secure, non-default passwords.Be protected by a stateful, network firewall that only accepts connections for approved, secure remote access services.
...
Advanced Computational Health Enclave
...
- Cryptographic and security configurations will be consistent with UIUC policies and standards of practice.
- These networks authenticate and authorize against the NCSA LDAP service, and are not used for guest access
- Like the default office subnets, the primary wireless network is firewalled or equivalently controlled to not allow servers for outside the NCSA IP space.
- The security team must have the ability to readily map wireless IPs and timestamps to users for at least 90 days.
- Only the NCSA and/or CITES networking teams have the ability and authority to configure access points and networking hardware for the wireless networks NCSA buildings.

NCSA Radiant User Zone
Definition:
This zone includes all of the virtual hosts running with the Radiant subnet. This includes all hosted environments even those supported by NCSA administrators for testing or operations.
Types of Systems:
This zone supports a variety of systems including user-owned VMs and user created servers and hosts.
Network Monitoring:
All links in and out of this zone are monitored by the NIDS. Network traffic entirely within this zone is unmonitored by the NIDS.
Informational & Procedural Requirements:
- System owners must follow all campus and NCSA policies regarding software updating, virus scanning, data security, incident reporting, etc.
Host Configuration Requirements:
- Systems do not bridge or create new NCSA subnets (wired or wireless) without approval from Networking & Security.
- Cryptographic and security configurations will be consistent with UIUC policies and standards of practice.
...
VPN Zone
Definition
NCSA offers a VPN services with different authentication profiles. These can be used as more flexible bastions in conjunction with firewall rules, to access privately addressed subnets, or to reach other services that might be blocked at the border (e.g., mounting filesystems).
...
Systems connected to the NCSA VPN are monitored unencrypted on the internal side of the VPN with the NIDS. Authentication to the VPN requires the use of valid and authorized NCSA credentials.
...
Physical Security Zone
Definition:
This is an isolated zone only for the NPCF physical security systems.
Types of Systems:
All NPCF physical security systems, and only those systems, are part of this zone. This includes the camera DVRs, badge readers, iris scanners, ACMS workstations (for badging, control and enrollment), and the ACMS database server.
Host Configuration Requirements:
- Devices on this network can neither connect to the other networks or be connected to except for a single ACMS workstation that must connect with iCard systems elsewhere on campus.
- This ACMS workstation can only be connected to via RDP from a single remote workstation run by Facilities & Services for troubleshooting and support.
- All other remote connections, even if temporary for support, must be approved by the Security Office.
...
Isolated Zones
Definition:
Sometimes there is a need for a special subnet that is treated no differently than an external network and does not route internally with NCSA systems. This could be because the systems on the subnet would not meet the requirements of this policy (e.g., they bring their own unmonitored WAN links or cannot be hardened sufficiently), it is actually an external network extruding into our physical infrastructure, or that external requirements or regulations require extra isolation.
