Measurement of system security issues of private computer networks for different types of attacks

In this thesis, two different types of Remote Access Virtual Private Network protocols (PPTP and SSL) have been established virtually using Virtual Lab. In addition, different types of security attacks have been applied to each protocol under the same conditions. For each attack, different tools were applied separately to each protocol. Moreover, the attacks were used to target different components for each VPN. The results were studied carefully, which led to obtaining a good security analysis used later to compare between those protocols under the test conditions and to give recommendations to use each of those protocols.
