    PDM install notes slightly askew

    ...on top of Debian that yields secure boot issues. Pretty much, if you perform a Debian install with custom partitioning with a nod to hardening compliance on partitions then install PBS, it breaks unless you revert to the Debian shim/grub. PBS doesnt (didnt?) force a custom kernel install but...

    CIS - Ensure SUID and SGID files are reviewed

    Hello, As part of Proxmox Hardening I need to review the below binaries and make sure that SUID or SGID permissions are required. These were listed by some Debian 13 hardening audit script (https://github.com/ovh/debian-cis/tree/master | 6.1.13_find_suid_files.sh & 6.1.14_find_sgid_files.sh)...

    Proxmox hardening - Proxmox iso vs Debian iso?

    Hi all, author of the hardening guide here. Thanks for bringing this up and sorry for seeing this post so late. Quick clarification, my guide is not saying you cannot or should not use the Proxmox ISO. Maybe I have to adjust the wording there more clearly? For most setups, the Proxmox ISO is...

    How to get multiply VLAN to work with Proxmox?

    ...easy access to other systems. It’s the same principle as using AppArmor, which confines applications to a defined set of resources via policy profiles to limiting what files, capabilities, and system functions they can access. Overall, it’s about hardening both the network and application access.

    Proxmox hardening - Proxmox iso vs Debian iso?

    This is most likely because, as far as I know, Proxmox is not designed for multi-tenancy, and it’s also not really supported in that sense, at least not multi-tenancy as VPS providers like Hetzner, DigitalOcean, or Linode implement it with full self-service portals, strict tenant isolation, etc...

    Proxmox hardening - Proxmox iso vs Debian iso?

    ...to perform compliance scans. For Proxmox there is no official benchmark available. We have to basically build a benchmark ourselves, probably based on the Debian hardening guide and other online information about Proxmox specifics. This should be something we expect from the vendor, Proxmox.

Assuming that the Proxmox ISO is unusable in a production environment soley based on some online hardening guide you stumbled over is, in my opinion, a bit of a stretch.
