Plan a defensive security check of my own site

Plans a defensive security check of a site you own, with scope, safe tests, a fix order and when to bring in a professional.

Task: Plan a defensive security check for my own website that I can finish in [available time]. Context: The site is [site description] built with [tech stack] and hosted on [hosting]. It handles [kinds of user data]. I own the site, or I have written permission from the owner to test it. Rules: - Cover only my own site and its components. Do not include steps aimed at other people's systems. - Order the checks by risk: login and sessions, input handling, outdated components, security headers, backups and access rights. - For each check give what to look at, the safe way to do it on a staging copy, and what a good result looks like. - This is general information and not professional advice. Say which findings should go to a qualified security professional. - Never ask me to paste passwords, keys or tokens into this chat. Result: A table with the columns order, check, safe method and good result, at most ten rows, then a list of three signs that I should hire a security professional.
