![]() If you disclose your encryption key or it is stolen, the security of your information will be jeopardized.free Wi-Fi) or if there is malicious software on the organization’s network, a VPN may not be able to provide the level of security you are hoping for If you choose to use an untrusted network (e.g.Your organization may have increased levels of risks due to the following examples: Your organization should research a VPN service before purchasing it to ensure it is inline with their policies. VPNs can introduce security risks to your organization. Having two separate keys or credentials for encryption and decryption is called asymmetric cryptography. If possible, the configuration settings should require individuals receiving the encrypted data to enter authentication credentials in order to access the information. Your organization should have clear policies for employees who use a VPN to remotely access a work server. Your organization should assess what data is sent and accessed through a VPN and the value of this data to understand the risks associated with using a VPN. How can I protect the data being sent or accessed through a VPN? Third-party privacy: Used to secure a connection from a public access point (such as an airport or hotel Wi-Fi hotspot) to a third party VPN provider and redirect the user’s traffic to make it appear to originate from the third-party’s network. Host-to-host: Similar to remote-access VPN, but connecting a host to a specific resource on an enterprise network or another specific host. Host-to-gateway (remote-access): Used to provide remote access (such as a remote worker’s laptop or mobile device) to an enterprise network. Typically used to connect remote office sites. Gateway-to-gateway: Used to connect two networks by creating a VPN over a public network, and securing all of the traffic between them. The fifth and last ion is a computer monitor with an open padlock on the screen to represent “local access”.The fourth icon is three computer towers to represent the “server”.The third icon is a brick wall with flames on the top to represent a “firewall”.The second icon is a planet with a cloud around the top to represent the “internet”.The first icon is a laptop with a padlock on the screen the words “sent” under the padlock.The first four icons are also connected by two solid black lines to represent a VPN tunnel. There are five icons presented in the image all connected by a dotted green line that represents encrypted information. For heightened security, you should require credentials to both send and receive the encrypted data. Image demonstrates how a virtual private network (VPN) acts as a tunnel that allows your encrypted data to go through the internet securely, and away from malicious actors. Long description - Virtual Private Network (VPN) This user should be required to enter credentials to access the encrypted data on the organization’s network. In this figure, the end point of the data transfer is a specific server, which is accessed by a user. Most VPN gateways are built into the firewall. In this figure, we assume that the VPN tunnel ends once the data arrives at the organization’s firewall or VPN gateway. ![]() The encrypted data is sent through a “tunnel” that protects it from threat actors. The figure below shows how a remote user sends encrypted data to their organization’s server using a VPN. In this document, we introduce some of the risks and considerations your organization should understand before using VPN services. ![]() ![]() For example, a telework employee can use a VPN to send data that is encrypted until it reaches its destination (e.g. A VPN acts as a tunnel that you can use to send and receive secure data on an existing physical network. Alternate format: Virtual private networks (ITSAP.80.101) (PDF, 1.16 MB)Ī virtual private network (VPN) is a secure connection between two points, such as your laptop and your organization’s network. ![]()
