Why Does A Website Get Defaced?

Website Defacement can occur on websites that have security holes. Hackers do not usually target specific websites for an attack. So, why is a website a victim of defacing?

1. Weak Login Credentials

Most people use simple usernames and passwords to make them easy to remember. Use one password for multiple accounts. This step will make it easier for hackers to damage your website.

Weak Login Credentials

If your password is too simple, it will be easy to break into your website with brute force techniques. This technique makes use of bots to make thousands of attempts to guess login credentials.

2. Does not have an SSL certificate

When visitors visit your website, data is exchanged from the browser to the server. This data usually contains sensitive information such as login credentials.

Well, hackers can steal data when the data exchange process occurs. Usually, hackers will infiltrate and read sensitive information they find. Then, use it to make website defacement.

This will not be easy if you have an SSL certificate because all data will be encrypted. This means it takes more effort and time for hackers to carry out the action.

3. Inactive Antivirus and Firewall

Website platforms like WordPress do have good security. However, without antivirus and firewall protection, hackers still have a chance to infiltrate.

Therefore, if you don’t provide additional protection with a security plugin, you could fall victim to defacing your website. 

4. Using Vulnerable Themes and Plugins

WordPress themes and plugins are vulnerable to hacker attacks. Especially the ones that are rarely updated. This means that if you want to install plugins and themes on WordPress, make sure the rating and frequency of updates are first. 

Also, it’s important to use the latest version as soon as you receive a notification via the WordPress dashboard.

How to Protect Your Website from Defacement

The best way to avoid the effects of website defacement is, of course, by increasing the security level of your website. Below are some ways to improve your security system to avoid website defacement. Listen up!

Using the latest version will make it more difficult for hackers to deface websites. This is because any security holes found will be immediately resolved by the platform developer. In addition, the update step is easier to do, and you don’t have to wait for a long process. 

3. Create Difficult Login Credentials

Using difficult login credentials will increase the security of your website. Because hackers will find it more difficult to break into your website. To do this, change the default login with a unique username. Besides, use a long password with a combination of letters, numbers, and special characters. For example: “St0P1t! Y00”.

Create Difficult Login Credentials

If necessary, you can also install a security plugin that limits login attempts. So, it can reduce the possibility of brute force attacks on your website. 

4. Perform Periodic Backups

Backup steps are important to avoid unwanted things like defacing a website. 

If your website is damaged, you can still restore it to normal with the backup files you have. 

You can perform backups manually or automatically using plugins. For example, for WordPress users, you can use the WP Backup plugin. With simple steps, your assets can be saved first in anticipation of hackers.

5. Scan for Malware Routinely

Malware can enter your website system without realizing it. If left unchecked, the level of damage can be even more severe. Therefore, it is important to perform regular malware scans.

For Niagahoster users, you can take Imunify360, which is more effective in dealing with malware. 

6. Manage User Access Rights

Setting user permissions is equally important. If you haven’t already, do so immediately. Moreover, managing permissions on a platform like WordPress is quite easy. 

User permissions will control how far a user can make changes to the website. The highest rights belong to an admin. Therefore, make sure only trusted people have this access right. 

If admin permissions fall to the wrong person or hacker, you might fall victim to defacing the website.

7. Turn off Debugging Mode

Displaying error message information to users is quite dangerous. A lot of information can be used to find holes in your website’s security. For example, a username that can appear in the error message. 

One way around this is to turn off debugging mode. With this step, you can disable PHP reporting in your WordPress.

To do this, you can make changes to the php wp-config configuration as shown below:



ini_set(‘error_reporting’, E_ALL );

define(‘WP_DEBUG’, false);

define(‘WP_DEBUG_LOG’, true);

define(‘WP_DEBUG_DISPLAY’, false);

With these changes, it is hoped that there will be no more detailed error information when visitors access your website.

8. Use HTTPS


HTTPS is a protocol used to ensure the security of data exchange on your website. So, there is no intrusion in the request process from the user to the server.

The use of HTTP is very important, especially for those who have an online store, website forum, or membership. The reason is, this type of website requests and manages sensitive website visitor information. With the HTTPS protocol, the security can be further enhanced. 

Besides, Google also prefers websites that use HTTPS. This means that if your website uses it, it will be prioritized on ranking in the search results.  

9. Protect Website from SQL Injection

SQL injection is often used by hackers to control a website. Usually, they will look for web pages that accept manual input, such as a form to enter a certain code.

Therefore, set what data can be used when filling out forms that will enter your database. Also, don’t forget to change the prefix on your database tables to increase security. 

Also, make sure always to scan SQL injection regularly and activate the firewall.
