As Proxy-Servers are commonly used as ports between privat and public networks, they are protected from attacks. To record the network traffic, statics can be compiled and attacks from public networks can be detected.
Furthermore Proxy-Server requests can buffered to service repeated requests more efficient.
What is a VPN?
A virtual privat network (VPN) is a secured connetions of computers or networks via internet. The used encryption takes care of the necessary protection. Sent data is tap-proof and can not be manipulated while transmitting. 2 applications proved themselves:
- »Site to Site« is used eg. to link multiple offices;
- »Site to End« is used for work at home and mobile acces for company rescources.
Through internet access, VPN is very cost-sufficient. The used data is saved in packages and encripted to develop a tunnel for the different channels.
