Re: SSL VPNs and security

[Tim <tim-security () sentinelchicken org>]

Hello MZ,

I think SSL VPNs are a pretty lame idea in the first place, but for the
specific problem you bring up, would the following design work around
this?

Set up a wildcard record, *.webvpn.example.org, pointing to the device.
The device then maps all internal domain names or IP addresses to a
unique hostname, such as:  internalhost.webvpn.example.org, or
192-168-0-1.webvpn.example.org, etc.

Wouldn't this properly segment different internal sites, such that an
XSS in one wouldn't impact the other?  If so, pay attention all SSL VPN
vendors: it is your free idea for the week.
