Abstract:
This project Title “Establishing a Secure Network System” is a communication
system between intra office and branch office. Access Control List (ACL), Firewall
and Virtual Private Network (VPN) are the most popular network security method.
Hot Standby Routing Protocol (HSRP) is a modern process of network backup
connection. For making the system more secure and realistic we use Port Address
Translation (PAT). For controlling the redundancy of switches we have used Rapid
Spanning-Tree Protocol (RSTP). After implementation of all the functions, the system
is tested in several stages and it works successfully as a prototype.
