WordPress itself is relatively secure, but you can still help with plugins and behaviour. It is absolutely essential to keep everything up to date. Not just WordPress itself, but any installed plugins. Unfortunately, it can sometimes happen that the creator of a plugin stops developing it, attackers find a security hole in it, which they exploit and can harm you.
There is another useful tip regarding plugins and templates – to be safe, never install them from unverified or generally substandard sources. Ideally, use the direct download and install option within WordPress, or use known and trusted servers.
WordPress security can also be addressed through various plugins, which we've covered a bit here, for example. Thanks to them, you can set up, for example, a limit on the number of logins, the introduction of two-factor login authentication, the possibility of renaming the input file, the introduction of Google reCaptcha, etc.
In addition to similar techniques for securing online elements, it's never a good idea to neglect offline tools – i.e. your computer and operating system. WordPress security will be better the moment you keep your computer up-to-date, have all available security patches downloaded and installed, and have strong and unique passwords everywhere. And it also doesn't hurt to not save your passwords in Total Commander.
We've written about WordPress security measures on our blog, and we've also warned about frequent bot attacks. We also recommend reading the security article on the official site.
