AVPN makes an internet connection more secure and offers both privacy and anonymity online. IIT(ISM) offers its users to access Campus e-resources while out of campus through VPN. IIT(ISM) Computer Centre has installed a Secure Socket Layer VPN (SSL-VPN) server to allow access to IIT(ISM) Campus LAN resources remotely through the Internet. SSL-VPN employs encryption and other strong security protocols and allows two devices to create a private, secure communications tunnel through the Internet. This ensures that only authorized users can access the IIT(ISM) network remotely through VPN.
