WordPress security: The most important security plugins

The im­por­tance of a secure password is often un­der­es­ti­mat­ed. Users should con­tin­u­al­ly refer to the WordPress password security tips as well as taking advantage of the ad­di­tion­al pro­tec­tion that plugins offer. The Limit Login Attempts plugin is a useful tool against hack attacks, which are clas­si­fied as so-called brute force attacks. This is where hackers try to decrypt a user’s login data by combining common passwords with the username. If they are suc­cess­ful they could leak data or make unau­tho­rized changes to the source code. During the hacking attempt thousands of passwords are entered into the system per minute. If you set the Limit Login Attempts plugin to disable after four failed attempts the hacker will have fewer login tries. The ad­min­is­tra­tor them­selves will not have a problem logging in since the plugin registers the IP address of each attempt. Many all-in-one solutions offer a firewall system as a premium feature, which protects against brute force attacks and provides you with the highest WordPress security.

The WP Secure Login plugin makes it possible to secure the account even more with a second password. The extra password is only ac­ces­si­ble on the Google app and is regularly renewed. The Two-Factor Au­then­ti­ca­tion plugin works in a similar way, allowing the user to play around with a second username and password.

So-called all-in-one solutions combine different security features in the form of a Wordpress security plugin. The aim is to prevent security breaches and to close any pre-existing instances, therefore making WordPress as secure as possible with just one simple plugin. An advantage of these all-in-one plugins, such as iThemes Security, is that they are suitable for users with rel­a­tive­ly little ex­pe­ri­ence. These essential features only require some basic knowledge, such as the Acunetix WP Security plugin, which can be installed by less advanced users. The plugin scans the website for any potential security threats. As well as iden­ti­fy­ing the problem, the user is also informed of which actions to take and which tools are needed to fix the problem. These plugins also come with extra features that  can then be used by more ex­pe­ri­enced users as a con­ve­nient tool. The Acunetix WP Security plugin also offers a password generator as well as a special data bank tool. The Bul­let­Proof Security plugin protects against specific attacks such as XSS, RFI, CRLF, CSRF, Base64, Code Injection und SQL Injection. Important source code files are par­tic­u­lar­ly protected.

With IONOS you will find many plugins already installed. Any ad­di­tion­al WordPress security plugins, as well as other ex­ten­sions, can be installed by the user. Just make sure to use trust­wor­thy sources and make sure they are up-to-date by using plugins such as the WP Update Notifier. Crude security breaches will be found and stopped in their tracks, but this can only happen if the plugins are up-to-date. The Update Notifier is not a security plugin in the tra­di­tion­al sense, but provides the most current and safest versions of plugins, themes and other in­stal­la­tions in the long run. IONOS customers profit from Safe Mode, which keeps all ap­pli­ca­tions up-to-date when activated during in­stal­la­tion.

If you want to control the security status of your website then the Security Ninja is rec­om­mend­ed. This plugin allows you to carry out around 30 tests on your website, including one that stim­u­lates a brute force attack. Weak areas can be iden­ti­fied and quickly fixed thanks to the plugin.
