Abstract:
1. A method for providing a secure access of a partner to the development environment of an owner comprising the steps of: starting a VPN tunnel between workstations to establish a secure encrypted tunnel end to end wherein each partner is identified with a different VPN group/password; starting a session by the partner in a Web page on a portal machine that authenticates through LDAP (Lightweight Directory Access Protocol) a user identification and password of user; routing the session to an engagement box depending on the user where the engagement boxes each include a server with an operating system and are on network segments separated by firewall boxes with another logon/password and is validated through second LDAP and wherein all users of the same partner are all launching on the same engagement box; accessing data and applications from an engagement box on Network File system storage authenticated second LDAP to a design zone common resource of said owner with a big compute farm composed of many high-end servers in a secure way, submitting batch or interactive jobs to said design zone; and providing for each application host in said design zone a highly secure access to EDA licenses from license servers with dynamically changing access ports of said owner inside an Intranet of said owner without opening all such access ports for all hosts and creating a security risk comprising the steps of: providing a license proxy server in said design zone that dynamically determines the addresses of the changing access ports of the license servers in said Intranet; and said application hosts inside said design zone contacting the license proxy server which in turn fetches the appropriate EDA licenses from said license servers in said Intranet of said owner.
