WordPress website are one of the most highly easy to manage CMS currently being used throughout the world because of its mere easiness to use backend.Any non-technical user would be able to install themes of liking and plugins to increase functionality on site.
Because CMS is easy to use, users do most common mistakes in WordPress website which needs to be avoided or else would lead to large scale vulnerabilities.
When you install WordPress , it comes with a default URL structure for accessing admin side.It means this page can be easily accessible to all the users who know this admin name. This has become one of the most crucial point for hacking of WordPress websites. Changed the name of admin to your like so that others cant access admin easily.
With admin, developers have most common habit of making mistakes by assigning world famous username admin to its second most famous password admin/123456.This has leaded another aspect for fishers and attackers to hack the site easily. Always generate strong and solid passwords and keep some nice username which cant caught easily by hackers.
Developer has tendency to install plugins while development and then not removing it from admin after the site is live. Unnecessary collection of plugins can reduce the speed of the website by considerable amount and even non technical client might get confused. Always keep files, images and plugins that are used in website and remove all unwanted things. This way website will run faster and admin will look neat and nice to use.
Another aspect of site getting injected is because of using default prefix that comes for tables. Always try to change wp_ prefix to some standard liking of your prefix. This will avoid hackers use common prefix for hacking tables.
Always make a habit of taking backups on regular basis and usually before doing any changes. Use Updraft Plus as best plugin for taking regular interval backups.
Whenever you install WordPress, comments are active by default. No matter what post you write, comments are always active. Accepting comment from spam or bots would always lead to site injection.
Avoid using links structure which has certain ID passed in URL. One cons is google will not index such pages and second is this sites are the most common to get hacked.
I have seen most common mistake non technical people do is they don’t update plugins or WordPress to latest version. They feel scare to update in case it may lead to stop certain functions on site. But in actual , updation is good because it involves lot of security patches, bug fixings and latest compatibility issues.
