Workarounds
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.
