This post was last updated on October 12th, 2021 at 10:05 pm

DDoS attacks can affect all websites, including WordPress-based ones. WordPress is an open platform that allows for many protection options. It’s all about prevention. To prevent an attack from happening or mitigate its effects, you must act now.

Do You Understand DDoS attack, and how can it be prevented?

It is an aggressive, coordinated attack by a network or computer compromised (a botnet) that massively requests or sends data from one server (the victim). The server capacity is overwhelmed by the flood of requests, which can slow down or cause it to crash because of a lack of resources.

DDoS Attacks Can Cause Severe Damage

Many bad things can happen to your website if it is the victim of a DDoS attack.

Take, for example:

  • The experience of your visitors could be negatively affected. The site’s response time can be slow at best. At worst, it could shut down completely.
  • Your website can be an online shop, which can primary to abandon sales. If it is just content, visitors might move anywhere to discover what they are searching for.
  • Your site prestige can be badly affected with regard to your well known brand fame (i.e., that your enterprise is not consider severe) and with regard to trust, relevance and authority, and that  are the foundations of any search engine optimization strategy.
  • Repairing the damage will cost you. It will vary depending on how long the attack lasted. The cost of repairs can be challenging to estimate because of many side effects, such as customer support efforts to resolve user complaints about service disruptions or hiring a security company to clean up your website.

Who Are The DDoS Victims?

DDoS attacks can target any website, regardless of its size or volume.

Websites with vulnerable vulnerabilities are the most common targets. However, any website can be targeted. Hacktivism is a form of hacktivism that targets ideologies. For example, you might use an attack to discredit websites that support specific religious or political ideas.

You could also try to blackmail the owner of the website and demand a ransom. It could be just a hobby for a group tech-savvy individuals who wish to showcase their skills.

A company can hire hackers to attack its competitors. No matter the reason, website owners must take steps to protect their sites from DDoS attacks. It’s not expensive or complicated, so there is no reason to.

What’s the distinction among  Brute force attack and DDoS Attack, exactly?

Brute Force Attacks attempt to hack into systems by trying random combinations to gain unauthorized access and  guessing passwords.

You can use DDoS attacks to crush the targeted system, making it unavailable or slowing it down.

What are the possible damages to your computer from a DDoS attack?

DDoS attacks can render websites unaccessible or slow down performance. The attack may result in a poor user experience and loss of business. It can also excel to lots of dollars in costs for mitigating it.

These costs are broken down:

  • Inaccessibility of the website can lead to business losses.
  • Answering service disruption-related questions requires customer support costs.
  • Security services and support are expensive for mitigating attacks.
  • Bad user experience and bad brand reputation are the highest costs.

How to Prevent and Stop DDoS Attacks on WordPress

DDoS attacks are often cleverly disguised and can be challenging to handle. You can stop DDoS attacks quickly by following some simple security tips.

These are the steps to follow to stop DDoS attacks from happening on your WordPress website.

DDoS/Brute Force Attack Verticals  Removal

WordPress’s greatest asset is its flexibility. WordPress lets you integrate third-party plugins into your website and include latest attributes.

WordPress offers several APIs that programmers can use to accomplish this. These APIs allow third-party WordPress plugins or services to interact with WordPress.

You use Some APIs to send a lot of requests, which could lead to a DDoS attack. To reduce the recommendations, you may switch of  them.

WordPress: Disable XML RPC

Third-party apps can interact with your WordPress website using XML-RPC.  You will need XMLRPC  if you want to utilize the mobile app of WordPress .

If you are like most users who do not use the mobile app, you can disable XMLRPC by adding the following code in your website’s .htaccess.

# # Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
order deny,allow
deny from all
</Files>

How may you Secure WordPress from DDoS attacks?

These are the two security steps you should take to protect your WordPress website from DDoS attacks.

  • A good WordPress backup solution is essential.
  • Use a cloud-based, cost-effective anti-DDoS security system.

Backup solutions are essential for many reasons. We won’t detail this topic as there are many paid and free backup options in the WordPress plugin catalog. If an attack has damaged your website, you can restore it quickly with a safety backup.

It would be best to consider how much security you need and how much you are willing to spend on anti-DDoS solutions. If you don’t want to spend anything, you’ll have to do many things yourself.

DIY approach

WordPress’ open architecture allows third-party apps to connect and interact with it. It is one of its greatest strengths. It is possible thanks to several APIs (Application Programming Interface), which are available to programmers.

You can use these APIs to send out a flood of requests by DDoS attacks. The first step is to disable XML-RPC, an exploitable API.

XML-RPC is required only if your WordPress site interacts with third-party apps, such as the WordPress mobile app. You can disable XMLRPC if you don’t need them.

To deny access to xmlrpc.php, you can edit your website’s .htaccess file. You can also get a plugin to do the job if you are unsure if it is safe to modify your website’s internal files.

Anti-DDoS plugins

There are several WordPress security plugins available that can fix other WordPress vulnerabilities.
