Encrypt temporary file properties
Temporary files are used in IBM® Cognos® Analytics with Watson to store recently viewed reports and to store data used by the services during processing. You can change the location of the temporary files and you can choose to turn off the encryption of the content.
By default, IBM Cognos components store temporary files in the install_location\temp directory and the files are not encrypted.
For optimum security, deny all access to the temp directory, except for the service account used to start the IBM Cognos services. Read and write permissions are required for the service account.
