A method for remote access, comprising: obtaining, by a Virtual Private Network, VPN, server, trust data of a user accessing a first network wherein the first network is a network to which the user wants to have remote access, and is divided into a plurality of access zones, each of which is a dedicated or shared network comprised of a sub-network; determining, by the VPN server, a first trust level corresponding to the trust data according to a first correspondence, wherein the first correspondence comprises the trust data and the first trust level; determining, by the VPN server, a first access zone of the first network corresponding to the first trust level according to a second correspondence, wherein the second correspondence comprises the first trust level and the first access zone; and establishing, by the VPN server, a first VPN connection between a device used by the user and the first access zone, the method further comprising: monitoring, by the VPN server, a change of the trust data; determining, by the VPN server, a second trust level corresponding to changed trust data according to a third correspondence if the VPN server obtains the changed trust data, wherein the third correspondence comprises the changed trust data and the second trust level; determining, by the VPN server, a second access zone of the first network corresponding to the second trust level according to a fourth correspondence, wherein the fourth correspondence comprises the second trust level and the second access zone; and establishing, by the VPN server, a second VPN connection between the device and the second access zone. obtaining, by a Virtual Private Network, VPN, server, trust data of a user accessing a first network wherein the first network is a network to which the user wants to have remote access, and is divided into a plurality of access zones, each of which is a dedicated or shared network comprised of a sub-network; determining, by the VPN server, a first trust level corresponding to the trust data according to a first correspondence, wherein the first correspondence comprises the trust data and the first trust level; determining, by the VPN server, a first access zone of the first network corresponding to the first trust level according to a second correspondence, wherein the second correspondence comprises the first trust level and the first access zone; and establishing, by the VPN server, a first VPN connection between a device used by the user and the first access zone, the method further comprising: monitoring, by the VPN server, a change of the trust data; determining, by the VPN server, a second trust level corresponding to changed trust data according to a third correspondence if the VPN server obtains the changed trust data, wherein the third correspondence comprises the changed trust data and the second trust level; determining, by the VPN server, a second access zone of the first network corresponding to the second trust level according to a fourth correspondence, wherein the fourth correspondence comprises the second trust level and the second access zone; and establishing, by the VPN server, a second VPN connection between the device and the second access zone. monitoring, by the VPN server, a change of the trust data; determining, by the VPN server, a second trust level corresponding to changed trust data according to a third correspondence if the VPN server obtains the changed trust data, wherein the third correspondence comprises the changed trust data and the second trust level; determining, by the VPN server, a second access zone of the first network corresponding to the second trust level according to a fourth correspondence, wherein the fourth correspondence comprises the second trust level and the second access zone; and establishing, by the VPN server, a second VPN connection between the device and the second access zone.
