    Running EDR on PVE Host

    ...practically require a SIEM to detect malicious activity, because it’s just a user (eg apache) that runs code within its permitted bounds. SELinux and other hardening tools simply make it better defined what the boundaries for those users are, something that is likely sorely missing from Windows.

    Running EDR on PVE Host

    ...and it should be treated as such. We harden all of our servers, and put security software on all of them, AV/EDR/XDR is not in lieu of hardening it's as well as hardening. It's seen as defence in depth, admin accounts do get compromised and perhaps an AV/EDR agent will pickup malicious...

    Running EDR on PVE Host

    ...list but his point still stands. Beside that before one installs a security software (no matter which) it's more important to do regular hardening of the Linux hosts like reconfiguring ssh to allow only public key or certificate authentication or other best practices of running Linux servers...

    PVE with antivirus

    I am not convinced of the supreme benefit of adding an antivirus to a hypervisor; it is really more a question of ticking a box, yes. It can be F-Secure, ClamAV, or another one. I haven't seen any official statement from Proxmox on this subject, that's why I'm asking here - and I don't have...

    PVE with antivirus

    ...you to believe you need antivirus on the host are probably the much bigger issue. If by “antivirus” you actually mean general security hardening or third-party security tools, they'd likely need to know which specific software you’re referring to. In that case, it would probably be best to...

    Cannot execute PVE 9 "root-only" commands in QEMU monitor even with "root@pam" token

    Hi, Looks like some monitor commands are too powerful to expose via API tokens and it was intentional security hardening. But you can use supported API calls instead of qom-set, many device changes (CPU, memory, disk, network) now have official API endpoints. For example, virtio-mem resizing...

    Why does proxmox-ve have a dependency on samba-common?

    ...directly (or indirectly) on Samba being present, even when CIFS/SMB storage is not configured or used. My Concern: From a security and hardening standpoint, it’s generally desirable to reduce the installed footprint and eliminate unnecessary network-exposed components. While Samba itself...

    [SOLVED] Hardening SSH

    ...1 node but not on the other (it does ask for OTP but is not accepted) Now with allowing password login and allowing root both examples work with no problem. Could someone shine some light on this? Maybe suggest some other hardening? (Firewall is active and only allowing a few IPs) Many...

    Proxmox VE auf VPS , Sicherheit

    Security: recommendations for going prod with pve

    That probably depends on your customers more than it does you. Having some exposure to the industry, I can tell you most studios will effectively give you their policies when you'll submit a vendor security questionnaire. "Proxmox" isnt really relevent in this conversation. Lynis produces a...

    Security: recommendations for going prod with pve

    ...also for the helpful links, we will go through each of them and check everything. Additionally I would like to add that we also found this hardening guide, which seems to be helpful (and may help other readers here later on, too). Be aware we still not verified it completely but we will work...

From the outset, we opted for an immutable infrastructure and place value on quality and “doing it right and...

    Proxmox server hardening document for compliance

    Hi y’all, I’ve released a Proxmox hardening guide (PVE 8 / PBS 3) that extends the CIS Debian 12 benchmark with Proxmox specific tasks. Repo: https://github.com/HomeSecExplorer/Proxmox-Hardening-Guide A few controls are not yet validated and are marked accordingly. If you have a lab and can...
