Let’s move on to Number THREE – Keep things up to date
Old technology is hackable. And yes a year in realtime is like three years online. Software patches and updates are developed and released all the time. Keep them up to date to prevent the worst of the attacks.
WordPress is the most commonly used website system. But it also vulnerable to the most types of hacking attempts. Keep your WordPress install up to date and all the plugins up to date and you’ll be protected well.
But if either of these get too old your website can be at risk.
Other systems like ModX are inherently much more secure, but not impenetrable. Last pass Modx site wordwide suffered a massive hacking attack.
