Security for the Web runtime begins with the following provisions:

Since we distribute the Web runtime via the Internet, it is packaged as a signed Cabinet (CAB) file. This ensures your users that the code is safe. The CAB file contains a compressed version of the control, with information that tells Internet Explorer how to install it.

Although we have built in a number of security features, the Web runtime allows COBOL programs to be executed on target machines. Because we have no control over the programs that are executed by the Web runtime, we cannot fully guarantee that they are safe.
