Additional security measures
Along with these WordPress plugins, you should also follow a few security measures from your side. These will help you in improving the security of your blog.
- Always keep your WordPress installation up to date. Update your WordPress as soon as possible if there is any new WordPress update. Most of the times, hacked websites are those which are using an older version of WordPress. Older versions of WordPress always have a few known security issues. And exploits for these security issues are available for free. Even a kid can hack your website if it is running on a vulnerable version of WordPress.
- Always keep plugins and themes added in your blog updates to latest version. New versions always come with new features and security fixes. So, updating plugins and themes is necessary. Most of the time, these third party plugins and themes are the reason for vulnerability in WordPress websites. Attackers can exploit these plugins to gain access to your website or inject malicious script in your website.
- Download themes and plugins only from trusted sources. Nulled themes and themes from untrusted sources generally contain malware in the code. If you install any security plugin, you will be notified, but why to take risk. Avoid any unknown source for download plugins and themes.
- Avoid using the administrator username ‘admin’, because this is default and common. By using this username in your blog, you are making the attacker’s work easier. He does not need to guess the username now, just bruteforce your website for username admin. Thanks to these plugins, bruteforce will not work anymore.
- Always use strong password for your WordPress account. WordPress bruteforcing tools are available. So, do not take the risk. Use a long password with capital letters, small case letters, numbers and special characters. A combination of these makes a strong password which is hard to guess.
These are few WordPress security plugins you can use to make your WordPress blog secure. You do not need to download all these plugins. Just try any one and see if it suits you. If you are not happy with its performance, you can download any other plugin to check and use. Every single plugin offers unique security features. You will feel relaxed after having any of these plugins in your website. Malware scanning, exploit scanning and brute force protection are few features which you must have in your website. If you have a good budget and do not want to be in technicalities, you can go for premium versions of the plugins which offer more advanced security features with detail reports. A few plugins also offer free customer support and security assessment with the pro version. With an increasing number of hacking attacks, it is necessary to have security in your website.
