FIREWALL: ACCESS CONTROL

Access to services can be controlled using any combination of the following attributes:
  • the service itself
  • the source or destination IP address and port
  • the time of day and day of week
  • available resources on the firewall
Very strong authentication is provided through a callback mechanism to the client using:
  • Identd for multi-user Unix systems
  • Windows NetBIOS lookups
  • S/Key One Time Password
  • RSA/DSA Challenge/Response
The last two are supported transparently on Windows 95/NT4.0 systems by the CEQURUX Authenticator.
