Virtual Private Network (VPN) Services





A VPN is a Virtual Private Network. A VPN is an alternative to a truly private network, where someone completely owns the infrastructure (i.e., wires) between locations and no one else can use it. Typically a VPN is used when some part of the network path crosses a public network such as the Internet or, in the case of wireless, "airspace." A VPN may also be used to provide additional security on private networks. The VPN builds an encrypted "tunnel" through a public/private network which provides the necessary confidentiality (this prevents snooping), sender authentication (this prevents identity spoofing), and data integrity for secure access to private resources. VPNs create paths of access into the network that must be looked at very carefully from the security perspective to only grant access to the areas required to perform the work. If a personal computer is used to connect to a VPN than the vulnerabilities and viruses that exist on the home computer now have access to the State resources the VPN group was designed with. For these reasons we must pay close attention to the configuration of these VPNs.

There are many types of VPNs but primarily can be grouped in two main types: client based (from your computer) and site-to-site (established between two networks using firewalls). The client based VPN uses software on your computer and two sets of authentications: Group Name / Group Password and User Name / User Password. With this configuration departments and agencies can have multiple groups to limit access to specific network areas. The site-to-site requirements a little more detailed and must be coordinated with the department IT staff to ensure proper design and security issues are addressed.

DII offers the following services:

  • LAN to LAN VPN (IPsec)
  • Client-Based (IPsec) VPN

LAN-to-LAN VPNs are used to connect remote networks to the State's WAN, generally to provide access to or from vendors. Remote-access VPNs are used to allow remote users' PCs to connect securely to resources on the State's WAN.





A VPN client allows you to "tunnel" all of your traffic to the State network over an encrypted, authenticated link which terminates on the State’s private network on our VPN system. The VPN server decrypts your traffic and forwards it to its destination, but it changes the source address of your traffic from your ISP-assigned address to a State assigned address. This way, all of your traffic appears to be coming from the State network and may not be limited by Internet firewall rules.

  • Provides data integrity and/or data confidentiality
  • Can also be combined with authentication and authorization mechanisms
  • Provides secure encrypted remote access to information protected by the firewall
  • DII Network Security Analysts provide consultation regarding service options and recommend best practices security policies
