Securing a WordPress site is usually regarded as the process of hardening as it relates to adding more security features to a website that is built on a secure WordPress platform. There are multiple aspects of reinforcing the WP site and some of these are elucidated in this article.
Just about four years ago as many as 73 percent of WordPress blogs were perceived as being vulnerable. Some of the commercially available plugins were responsible for such massive vulnerability including even a security plugin.
Security of any WordPress site stands to get compromised addition of more and more plugins, since the WordPress is found to be having a secure core. It should also be noted that more number of users can also impact security of a WP site.
Your WordPress site can be secured by a simple process of keeping the same updated by clicking the update button available on your dashboard. It is advisable to backup your mission critical data while executing an update.
While updating your site you also need to update various themes and plugins to keep security holes at bay. If you fail to update plugins and themes on regular basis, then you are almost leaving the doors of your site wide open for intruders to infiltrate.
Getting rid of unused plugins
While you are spending time in updating your site, you should also not overlook the fact that old plugins that remain untapped need to be discarded. Instead of deactivation of such plugins it is recommended to actually delete these.
The safest way to procure secure themes and plugins is to rely on right source. These must be scanned appropriately before admitting into directories for themes and plugins. Security of wp-config.php must be ensured by adding <files wp-config.php> order allow, deny, deny for all -code to .htaccess file.
Importance of strong username and password
You should never configure directories with 777 permissions and choose 750 or 755 as an alternative option. Many users keep their username as a simple ‘admin’ and this should be changed by inserting SQL query in PHPMyAdmin.
Password needs to be changed frequently and you should choose a strong one that comprises alphabets as well as numerical for added security. You can also leverage a reputed password generator for this.
The policy of choosing a strong combination of username and password should also be extended to your users. Brute force attacks can best be prevented by using a two-factor authentication. The process consists of using a password in combination with a randomly generated code that is commonly sent in the form of an SMS.
Your site deserves a firewall on your computer for protecting your digital assets from getting hacked by cyber criminals.
By limiting the login attempts or providing captcha, you can gain an effective defense against brute force attacks that rely on multiple an automated logins. There are many resources such as Login LockDown that restrict number of logins from the same IP.
Permissions and access restrictions
It pays to limit number of contributors that would be able to access your system at any given time. Moreover, you should set permissions of accessing your site’s admin area, so that only the authorized personnel are granted permissions. You can also define the extent of administrative access to ensure that only limited access is allowed to the staff depending on their credentials.
There is no point in allowing uninterrupted admin access to all users because of obvious reasons.
Security scans and backups
Security of WordPress site can be significantly enhanced by implementation of regular and scheduled backups to limit the impact of any unforeseen trouble including ransomware. The backup facility should be ideally located at a remote data center facility.
There are many versions of security scanners that can be entrusted to check for any vulnerabilities in plugins, themes or core files just to name a few. While choosing themes, you need to be very choosy as more themes may impact your site’s speed drastically. Limited number of themes or plugins can also help mitigate probability of hackers intruding your mission critical website.
There is more to your WP site’s security than meets the eye and therefore one must try to develop a robust strategy for site’s security.
