... problems
Most of the vendor products available on market today do not have the
features needed to handle the threats or implement the solutions =>
need for customized/homemade network elements
VPN IPSEC implementations and their interoperability (key exchange
and authentication)
Faked servers and services can still cause trouble within one cell =>
need for network elements that can handle also this kind of problems,
and also need of user education
Double tunneling if two VPNs are used, one to secure access through
radio way and other to connect for example company intranet
What if some devices / users do / can not have an interoperable VPN
client installed?
How to create and combine public access to this scenario?
