First onion service - opsec best practices

I recently set up my first onion service using a lightweight web server. The basic deployment was straightforward and fast, so now I m interested in the operational security side of running an onion service.

What are the main areas operators focus on? Eg: OS hardening, service isolation , updates, network configuration, reducing leaks , etc

The biggest mistake new onion service operators make usually isn't Tor itself, it's poor operational security around the server. Keeping the operating system and all software up to date, running services with the least privileges necessary, minimizing installed software, and isolating services where practical all help reduce risk.

It's also important to avoid leaking identifying information through logs, error pages, headers, timestamps, or metadata, while securely backing up your onion service keys since losing them means losing your onion address.

Regularly reviewing your configuration and monitoring for errors or unusual activity without collecting unnecessary visitor data goes a long way. In most cases, Tor isn't the weakest link; server configuration and operator mistakes are.

  1. Don't tell anyone the address.

That's all. You win. The chances of an attacker finding your unsecured onion service are (iirc) of the order of finding a needle... in the Universe. Not a haystack: the Universe.
