VPN (Virtual Private Network) is utilized for general outside users to communicate securely with inner users and the servers located inside by an encryption for safe communication. VPN has various techniques and functions on the layer 2 and 3, thus this study examined whether layer of VPN performed encryption of the data more securely and is more effective in the 2 layers of VPN techniques. Based on the results of the test, the layer 3 VPN technique was confirmed to communicate with inner space with faster speed than that of the layer 2. And in comparison with encryption protocol supporting in the layer 2 and 3, IPSec VPN of the layer 3 VPN technique was more superior in the function of encryption.
