Vendor Workaround

AVEVA alternatively recommends the following actions users can take to mitigate risk: * Apply host and/or network firewall rules restricting the taoimr service to accept traffic only from trusted source(s). By default, AVEVA Process Optimization listens on port 8888/8889(TLS). Please refer to the AVEVA Process Optimization Installation Guide for additional details on ports configuration. * Apply ACLs to the installation and data folders, limiting write-access to trusted users only. * Maintain a trusted chain-of-custody on Process Optimization project files during creation, modification, distribution, backups, and use.
