However as is frequently the case, such features can likewise open the door to harmful attacks.
To alleviate versus such threats, CISA and DoE are encouraging companies to identify and detach all UPS systems from the internet and gate them behind a virtual private network (VPN) in addition to enforce multi-factor authentication.
The companies have likewise urged worried entities to upgrade the UPS usernames and passwords to make sure that they don’t match the factory default settings. “This guarantees that going forward, hazard actors can not utilize their knowledge of default passwords to access your UPS,” the advisory read.
