Nokia has boosted the security and functionality of its Secure Access System Secure Socket Layer virtual private network (VPN) platform.

Secure Access System provides secure remote access to email, personal information management data, corporate intranets and applications from any public internet kiosk, terminal, laptop or wireless device.

The latest version, 2.1, introduces a Secure Workplace feature designed to maximise security by boosting traditional cache cleaning or application wiping to better ensure the security of important information.

The package is designed to create a separate work environment on laptops, home PCs, public kiosk terminals or other remote access devices to safeguard data created in a secure session.

By disabling copying and pasting from the secure environment to any non-secure applications it prevents users from inadvertently sharing sensitive information.

"Nokia Secure Access System 2.1 soundly balances security and user freedom, implementing strong security measures without impacting where and how users want to work," said Elie Habib, senior vice president of security and mobile connectivity at Nokia Enterprise Solutions, in a statement.

"The addition of Secure Workspace, combined with existing performance, reliability, and manageability, make Nokia Secure Access System an easy and effective way for companies to realise the benefits of secure mobility."

Secure Access System deletes temporary browser cache files, cookies, history and bookmarks on logout and overwrites all of the removed files multiple times to ensure that data cannot be recovered.

The latest release of the platform is designed to remove only the new files associated with the secure session, while leaving other, unrelated cache files on the system.

Nokia Secure Access System 2.1 is available, without additional licence fees, with the purchase of any Nokia Secure Access System appliance. Existing customers with software subscriptions or other support offerings can download version 2.1 at no additional cost.
