What is SSL VPN?
An SSL VPN is a type of virtual private network ( VPN) that uses the Secure Sockets Layer ( SSL) protocol -- or, more often, its successor, the Transport Layer Security ( TLS) protocol -- in standard web browsers to provide secure, remote access VPN capability.
Why use SSL VPN?
The primary reason to use an SSL VPN product is to prevent unauthorized parties from eavesdropping on network communications and extracting or modifying sensitive data. SSL VPN systems offer secure and flexible options for enterprise employees, telecommuters and contractors to remotely connect to private enterprise networks.
What is VPN split tunneling?
VPN split tunneling enables a single VPN client to reach more than one destination.
What is SSL tunnel?
An SSL tunnel VPN enables users to securely access multiple network services via standard web browsers, as well as other protocols and applications that are not web-based. The VPN tunnel is a circuit established between the remote user and the VPN server; the server can connect to one or more remote websites, network services or resources at a time on behalf of the client. The SSL tunnel VPN requires the web browser to handle active content and provide functionality that is not otherwise accessible through an SSL portal VPN.
What layer does L2TP use?
L2TP operates at the data link layer -- Layer 2 -- of the Open Systems Interconnection (OSI) networking model, while IPsec operates at the OSI network layer -- Layer 3. This means that more networking metadata can be encrypted when using those tunneling methods, but it also requires additional software and configuration to create VPNs with those protocols.
What happens when you authenticate to IPsec?
Also, once the user is authenticated to an IPsec VPN, the client computer has full access to the entire private network, which violates the principle of least privilege ( POLP) and, as a result, may expose some private resources to attack.
Is SSL VPN secure?
Despite the benefits an SSL VPN provides, security risks are also associated with the technology. Notwithstanding its enhanced security measures, an SSL network can be susceptible to spreading malware, including spyware, worms, viruses and Trojan horse programs.
