Update WordPress Version
Hackers find it difficult to deal with the latest version of WordPress, because it has an updated security system. Whenever using WordPress for your blog, make sure you have the fresh version. You can get an idea about the new versions simply by following WordPress feed.
Change Login/Password regularly
‘Admin’ by default comes as login and the hackers know this very well. So, you must quickly change your login name. Choose a unique one, so the hacker finds it difficult to guess.
The best option however is to delete the default admin and create an entirely new custom login. Use strong password and change it on regular basis. Examples of strong passwords are: rockySUPERSTAR93!@” and “Mitchellb7e@”.
Block Directory Browsing
Allowing the visitors to browse through your complete directory could prove expensive. By having a through look at the directory structure, the hackers can easily sway things in their favour.
Carefully Use Plugins
Stay really careful, when it comes to use new plugins, scripts and layouts. You may find hundreds of plugins on Internet, but before installation make sure the plugin comes from a trusted source and does not contain spy-ware.
Choose Trusted Themes
Many WordPress themes came with hidden links and advertisement. Therefore, you should always get the theme from a reputable source. Make sure the theme you are selecting is already being used by others.
