What is the difference between Abtrusion Protector and Software Restriction Policies?

Software Restriction Policies is a tool to restrict which software may be run on Windows XP. It enables an administrator to allow or deny certain software based on path and name.

Some of the limitations of Software Restriction Policies are:

  • Software Restriction Policies normally depend on the extension of the file, the path and the file name to determine which software should be allowed. Such rules can often easily be by-passed by viruses, hackers or rough users.

  • In theory, Software Restriction Policies also allow you to restrict software based on digital thumbprint/hash value. However, with Software Restriction Policies it is virtually impossible to manage such a policy in a safe way. Abtrusion Protector includes several features to automatically and securely update software permissions when installing new software.

  • Software Restriction Policies do not apply to drivers and kernel mode components. They also do not apply to most services or to users with administrative privileges. Abtrusion Protector policies applies to all executable software components, regardless of their function.

  • By default, Software Restriction Policies do not apply to dynamic link libraries. It is possible to configure Software Restriction Policies to restrict dynamical link libraries, but in practice it would be very difficult to maintain such a policy.

  • Software Restriction Policies do not work on Windows NT 4.0 or Windows 2000.

Some of the good features of Software Restriction Policies are:

  • They can be used to restrict the software Windows Installer is allowed to install. Abtrusion Protector can be set-up to automatically allow software installed by Windows Installer. Together, these two features can be used to securely install new software.

  • Software Restriction Policies can be used to restrict access to certain types of scripts.

  • Software Restriction Policies is a good tool to restrict which user may run which application. In a network, it is possible to deny access to certain applications from users that don't need them. This is probably the most useful application of Software Restriction Policies.
