Firewall Protection and Intrusion Detection

  • All servers involved in the Virtual Desktop are positioned behind a firewall. Changes to the firewall rules must be approved by the CDT Information Security Officer (ISO).
  • Connections to the Virtual Desktop environment are routed through a redundant Demilitarized Zone (DMZ) accessed via SSL only.
  • Connections are double encrypted and compressed. A 128-bit SSL digital certificate provides the first layer of encryption. The second layer is provided via the Independent Computing Architecture (ICA) encryption and compression algorithm.
  • Access security is enhanced by the use of a secure token code along with the standard user ID and strong passwords

Secure Tokens
