WordPress Security Checklist: Lock Down Your Site
Most WordPress hacks come from outdated plugins, weak passwords, and skipped updates. This checklist covers the practical steps that prevent the vast majority of attacks.
TL;DR
Most WordPress hacks are preventable. Keep core, themes, and plugins updated, use strong passwords and two-factor auth, limit login attempts, install only reputable plugins, enforce SSL, run automated backups, add a security plugin or firewall, use least-privilege user roles, and choose quality hosting. Do these and you avoid the overwhelming majority of attacks.
WordPress powers a huge share of the web, which makes it a constant target, mostly through automated bots probing for known weaknesses. The good news: almost all of those attacks exploit the same handful of avoidable gaps. Work through this checklist and your site is dramatically harder to compromise.
Why WordPress sites get targeted
Attackers rarely target a specific small business site by name. They run bots that scan for outdated plugins, weak logins, and known vulnerabilities at scale. That means basic, consistent hygiene stops most of it, you do not need to be a security expert, just disciplined.
The checklist
- Update everything: WordPress core, themes, and plugins, promptly. Outdated plugins are the number one entry point.
- Strong auth: strong, unique passwords and two-factor authentication on all admin accounts.
- Limit logins: cap failed login attempts and avoid the default admin username.
- Reputable plugins only: install from trusted sources, actively maintained, and remove anything unused.
- SSL everywhere: enforce HTTPS across the whole site.
- Automated backups: regular, off-site backups you have actually tested restoring.
- Security plugin or firewall: a reputable security plugin or a web application firewall to block known attacks.
- Least-privilege users: give each person the lowest role they need; not everyone needs admin.
- Quality hosting: good hosts add server-level protection and isolation.
If you do get hacked
Do not panic. Take the site offline or into maintenance mode, restore from a clean backup, change all passwords and salts, update everything, scan for malware, and identify the entry point so it does not happen again. If that is beyond your comfort level, get help quickly, the longer a compromise sits, the more damage it does.
