Internet Security Systems (ISS) has announced an upgrade to its RealSecure Desktop Protector software that provides security features on desktop PCs.

Version 3.5 of RealSecure Desktop Protector will allow users more flexibility in how the software protects them during virtual private network (VPN) sessions, Dan Naider, director of RealSecure product solutions at ISS, said. Users will now be able to tell the software where they are connecting from via a VPN - be it remotely, inside a network or from other locations - and the software will adjust its protection level accordingly, he said.

Such a change will allow users to maintain a level of protection, take advantage of the security measures afforded to them by the network they are on and use services and applications they might not be able to access with stricter security, he added.

ISS has also announced the addition of application protection to Desktop Protector. Application protection is a new feature that prevents unauthorised or unwanted applications from running by cryptographically signing each application, Naider said.

When a user or administrator installs the new version of the software, it will scan their PC to determine what applications are installed on it and will create a checksum, or mathematical signature, for each application, he said. When an application without a checksum tries to run, it will be blocked from doing so, he said.

The software can be configured to present a pop-up window offering the user the option to run the application when an unauthorised program tries to run, he added. Checksums can be generated when new software is installed, he said. The software also allows users to lock their systems to prevent unauthorised writing of files, Naider said.

Application protection will allow users to block the spread of worms and Trojan horses, since those applications will not have checksums and therefore will not be able to run, he said. Naider did caution that users should run a virus scan before creating the checksums to avoid unintentionally authorising any viruses or worms that may already be on their systems.

The new software is immediately available worldwide, at a cost of $2,500 (£1,632) for 25 users with the corporate version or about $60 (£39) per user with the consumer version.
