Most security checklists are long because covering everything looks thorough. Here's the shorter, more honest version — the items that address how sites actually get compromised.
The majority of website compromises happen through known, already-patched vulnerabilities in outdated software — not sophisticated zero-day attacks. If you run WordPress or a similar CMS, an outdated plugin is the single most common entry point.
Reused passwords mean one breach elsewhere becomes a breach of your site too, via credential-stuffing attacks that try leaked password lists against your login page.
Free SSL certificates removed any excuse for this years ago. Beyond the trust signal, HTTPS prevents attackers on shared networks from intercepting login credentials.
Not just backups that exist — backups you've actually restored from at least once, so you know the restore process works before you need it under pressure.
Brute-force login attempts against admin panels are constant background noise on the internet. Rate-limiting or lockout after failed attempts stops the vast majority of it.
Every installed plugin is a potential vulnerability, even one you never activated. Unused software isn't neutral — it's attack surface with no benefit.
Covered in more depth in our WAF vs firewall guide — this catches malicious form submissions and injection attempts before they reach your application.
If your site accepts file uploads (images, documents, resumes), make sure uploaded files can't be executed as scripts — a common path for attackers to gain code execution.
File integrity monitoring or even a simple alert on unexpected admin account creation catches a compromise early, before it escalates.
Knowing who to call, how to take the site offline quickly, and how to restore from backup — decided in advance, not figured out during the incident.
A forty-item checklist tends to get skimmed once and abandoned, since completing it feels like a major project rather than a routine task. Ten items that address the actual majority of real compromise vectors are far more likely to get done, and revisited periodically, than a comprehensive list that intimidates more than it protects. Thoroughness that never gets acted on provides less real security than a shorter list that's genuinely maintained.
Running through this list once and considering security "done" misses that several items — updates, backup testing, unused plugin cleanup — need to happen repeatedly, not once. Setting a recurring quarterly reminder to re-check the full list keeps it a maintained practice rather than a one-time setup that quietly decays as the site changes over time.
Even in a small business without a dedicated security role, assigning one specific person as responsible for periodically running through this list prevents the common failure mode where everyone assumes someone else is handling it. Explicit ownership, even informally, is what actually determines whether a checklist gets revisited or quietly forgotten after the first pass.
