These issues must be dealt with appropriately to ensure the confidentiality and integrity of data and information, as well as overall corporate network security. While providing significant business benefits and cost savings, VPN technologies (SSL VPN included) come with their own security issues.

For broader application access, a dynamically downloadable tunneling client is typically delivered when needed to the client machine to support such full SSL VPN capabilities.

If application access requirements are modest, SSL VPN does not require additional client software to be installed on the endpoint device. A complete SSL VPN, on the other hand, is a VPN that provides all VPN characteristics and local LAN user experience (in terms of network access). The latter is an application gateway that supports a certain type of applications. There is a difference between a full VPN tunnel and an SSL-enabled proxy server. This means that even if a particular local environment does not permit outbound IPSec VPN sessions (such restriction is not unusual), SSL VPN is likely free of such restriction. In most environments, outbound Secure HTTP (HTTPS) traffic, which is also based on SSL, is not blocked. One SSL VPN advantage for end users is in the area of outbound connection security. End users may even choose their favorite web browsers without being restricted by the operating system. SSL VPN, on the other hand, requires only a modern web browser. Different IPSec VPN vendors may have different implementation and configuration requirements. As a result, SSL VPN is also known as “clientless VPN” or “Web VPN.”Īnother SSL VPN advantage over IPSec VPN is its ease of use for end users.

Unlike traditional IP Security (IPSec) remote-access VPN technology, which requires installation of IPSec client software on a client machine before a connection can be established, users typically do not need to install client software in order to use SSL VPN. Today, this SSL/TLS function exists ubiquitously in modern web browsers. Most noticeably, SSL VPN uses SSL protocol and its successor, Transport Layer Security (TLS), to provide a secure connection between remote users and internal network resources. SSL VPN has some unique features when compared with other existing VPN technologies. Security mechanisms that can be used for risk mitigation are also discussed. This paper addresses security issues and challenges associated with SSL VPN, including general VPN security and specific SSL VPN security, as well as endpoint device security and information protection. SSL VPN allows users from any Internet-enabled location to launch a web browser to establish remote-access VPN connections, thus promising productivity enhancements and improved availability, as well as further IT cost reduction for VPN client software and support.Īdditional VPN background information is widely available. Secure Sockets Layer (SSL) VPN is an emerging technology that provides remote-access VPN capability, using the SSL function that is already built into a modern web browser. Productivity enhancements can be measured in terms of tool effectiveness, user time savings, usability improvements, and user satisfaction.

The total ownership cost can be considered as the initial deployment cost plus the cost of user training, support, and facility maintenance over time. There are many reasons for such overwhelming adoption and business success two major factors are total ownership cost savings and productivity enhancements.
In recent years, various virtual private network (VPN) technologies have been widely used to provide secure site-to-site connectivity and remote access.
