I can only answer the first question The OS for the latest version I'm running isOME 3.9.0.55  -  OS: CentOS Linux7 (3.10.0-1160259.1.el7.x86_64) The other questions are answered in the threat you mentioned.This hasn't changed with the new version I guess.Because there is no console access or SSH access to the OS, it will be very unlikely that you can install somethin inside the appliance. This is also the security protection of OME against attacks I think.
Hi Dell Community, My company is deploying Dell OpenManager Enterprise 3.8.3 appliance. For every new server/appliance, we have a standard suite of software that either need to be installed or remotely access the OS via local service accounts. I would greatly appreciate any help with the following questions. Thank you in advance 1) What is the OS used in Dell OME 3.8.3 appliance; is it CentOS 8? 2) Does Dell allow 3rd party software agents to be installed on OME operating system? If yes, where can I find documentation on the host-based security controls (e.g. SELinux, firewalls) that need to be updated? 3) Does Dell allow local service accounts to be created on OME operating system, for remote login/access by external systems? Thank you PS: I am aware of the thread below however there are differences in the questions and software baselines:  [URL]
