Nextcloud zero day security - eviltoast

What is everyone doing? SELinux? AppArmor? Something else?

I currently leave my nextcloud exposed to the Internet. It runs in a VM behind an nginx reverse proxy on the VM itself, and then my OPNSense router runs nginx with WAF rules. I enforce 2fa and don’t allow sign-ups.

My goal is protecting against ransomware and zerodays (as much as possible). I don’t do random clicking on links in emails or anything like that, but I’m not sure how people get hit with ransomware. I keep nextcloud updated (subscribed to RSS update feed) frequently and the VM updates everyday and reboots when necessary. I’m running the latest php-fpm and that just comes from repos so it gets updated too. HTTPS on the lan with certificates maintained by my router, and LE certs for the Internet side.

Beside hiding this thing behind a VPN (which I’m not prepared to do currently), is there anything else I’m overlooking?

    I use and love Kopia for all my backups: local, LAN, and cloud.

    Kopia creates snapshots of the files and directories you designate, then encrypts these snapshots before they leave your computer, and finally uploads these encrypted snapshots to cloud/network/local storage called a repository. Snapshots are maintained as a set of historical point-in-time records based on policies that you define.

    Kopia uses content-addressable storage for snapshots, which has many benefits:

    Each snapshot is always incremental. This means that all data is uploaded once to the repository based on file content, and a file is only re-uploaded to the repository if the file is modified. Kopia uses file splitting based on rolling hash, which allows efficient handling of changes to very large files: any file that gets modified is efficiently snapshotted by only uploading the changed parts and not the entire file.

    Multiple copies of the same file will be stored once. This is known as deduplication and saves you a lot of storage space (i.e., saves you money).

    After moving or renaming even large files, Kopia can recognize that they have the same content and won’t need to upload them again.

    Multiple users or computers can share the same repository: if different users have the same files, the files are uploaded only once as Kopia deduplicates content across the entire repository.

    There’s a ton of other great features but that’s most relevant to what you asked.
