Are you aware what’s a DDoS assault? And how are you going to defend your web site from them? On this article, we’ll clarify what DDoS assaults are, discover what may make your web site weak, and how one can scale back their likelihood and impression.

What’s a DDoS Assault?

DDoS (Distributed Denial of Service) is commonly referred to as a easy denial of service. A DDoS assault consists of an internet site being flooded by requests throughout a brief time frame, with the goal of overwhelming the location and inflicting it to crash. The ‘distributed’ ingredient implies that these assaults are coming from a number of areas on the identical time, as in contrast to a DoS which comes from only one location.

In case your web site suffers a DDoS assault, you’ll obtain hundreds of requests from a number of sources over a interval of minutes or generally hours. These requests aren’t the results of an internet site abruptly getting a spike in traffic: they’re automated and will come from a restricted variety of sources, relying on the size of the assault. A DDoS assault isn’t the identical factor as hacking, though the 2 might be linked.

Why Would Somebody DDoS your web site?

So why would somebody mount a DDoS assault in your WordPress site? What might they’ve to achieve from it? There are various the reason why an attacker may need to put your web site out of motion through a DDoS assault. These embody assaults by opponents and assaults due to your content material.

DDoS Attacks by Opponents 

In an excellent world, your opponents would try to outperform you on-line by bettering their content material, website positioning, and conversion price, which is the authentic manner to use your web site to achieve a aggressive benefit.

However in some instances, opponents may take extra excessive measures. A competitor may rent somebody to mount a DDoS assault in your web site within the data that this received’t solely impression your web site, it’ll additionally impression what you are promoting.

Within the time it takes you to get your web site working once more, they are going to be taking enterprise from you, particularly if they’re operating advertisements utilizing what you are promoting identify as a key phrase. In case your web site isn’t up and operating once more rapidly, you’ll lose search rating and might discover that your opponents now rank above you on Google.

In fact, it’s very troublesome to show who carried out any DDoS assault. The assault received’t come out of your competitor’s IP handle! Except you’ve gotten very deep pockets, trying to take authorized motion in opposition to a competitor you think of doing that is unlikely to achieve success.

Much better to defend your self from the results of an assault within the first place. And don’t be tempted to mount one other DDoS assault in opposition to your competitor in response. That is unlawful and it’s much better to reassure your self {that a} competitor determined sufficient to use measures reminiscent of these in all probability received’t have the longevity or popularity that what you are promoting does.

DDoS Attacks on Your Content material

Some websites are topic to DDoS assaults due to the character of their content material. For instance, a whistleblowing web site is perhaps topic to an assault. A web site coping with a controversial concern (reminiscent of entry to abortion or anti-racism) may undergo assaults from individuals who disagree with its message and need to put it out of motion. Or your content material is perhaps business however nonetheless delicate and there are individuals who don’t need it accessible on-line.

In case your web site is efficiently attacked, it can put your content material out of circulation, which might trigger issues in your customers in the event that they want entry to data or steering. You’ll even be spending time resolving the difficulty, dropping any income you is perhaps making from the location (both in gross sales or donations if you’re a nonprofit), and your rankings can drop in case your web site is returning a 502 error for hours or days.

Politically Motivated DDoS Attacks

Politically motivated DDoS assaults have gotten extra frequent as cyber threats are more and more used to disrupt the political course of. In case your web site is for a political social gathering, candidate or group, or advances a particular political trigger, then it might be weak to assault from individuals who disagree along with your politics.

This received’t unnecessarily come out of your political opponents. It’s extra probably to come from exterior sources that search to disrupt political debate, block sure kinds of content material and use chaos to confuse and disenfranchise folks. The assault might be an try to make it not possible for folks to entry your content material (see above), or it might be a extra private assault on the person candidate or group behind the location.

That is completely different from a web site changing into overloaded due to spikes in visits due to the information cycle. I as soon as labored on the web site of a political social gathering which grew to become overwhelmed when the social gathering’s manifesto was launched for a common election. That was the primary UK election through which e-campaigning was vital and we simply weren’t ready for the quantity of site visitors.

As an alternative, a DDoS assault can be a lot sharper and extra abrupt, seeing a really sudden spike in requests for generally a matter of minutes. This may look very completely different from a pure spike in site visitors, which though it may be sudden will usually take the type of a curve as an alternative of a cliff.

In case you are operating a marketing campaign (which could have made you extra weak due to the additional publicity), then it will likely be significantly vital to guarantee your web site stays operational and not to waste time coping with the assault when you can be specializing in campaigning exercise. That’s why it’s essential to take the steps beneath to defend your web site from a politically motivated DDoS assault.

The Results of a DDoS Assault

A DDoS assault might need quite a lot of results, relying on the character of the assault and how ready you might be for it.

1. Web site Downtime

Probably the most speedy and apparent impact is that your web site is overwhelmed and turns into unavailable. This implies any enterprise you achieve through your web site received’t be accessible to you till you get the location working once more. It additionally impacts your popularity as an internet site proprietor. And when you don’t repair the location rapidly, it will probably have an effect on your website positioning as if Google crawls your web site and finds it out of motion, you’ll lose rank.

In case your web site is unavailable due to being overloaded, it can return a 502 dangerous gateway error, which is able to negatively impression your search rankings when you enable it to keep that manner for too lengthy. I’ve additionally seen assaults the place the location hasn’t been accessible for plenty of days (as a result of the proprietor didn’t understand how to repair it and hadn’t stored a backup, extra of which shortly), and when the location did return on-line, the entire inside hyperlinks in that web site’s Google listing had been misplaced.

2. Server and Internet hosting Points

In case your web site is topic to common assaults that you simply don’t take steps to mitigate, this might lead to points along with your internet hosting supplier. A good internet hosting supplier provides you with instruments to safe your web site in opposition to DDoS assaults however when you don’t have this and you’re on shared internet hosting, the assaults might impression different websites on the identical server.

3. Web site Vulnerability

A DDoS assault might render your web site extra weak to hacking as your entire methods are centered on getting the location again on-line, and safety methods might have been put out of motion by the assault. Hackers might then find it easier to make their way onto your web site through a again door as soon as the DDoS assault has succeeded in paralyzing your web site.

Comply with-up assaults like this received’t at all times come from the identical supply because the requests that shaped the DDoS assault: a intelligent hacker will understand how to cover their tracks and use a number of IP addresses to assault your web site, in addition to how to cover their actual location.

So if you’re the sufferer of a DDoS assault, one in all your first priorities ought to be making certain your WordPress web site is safe. That is arguably extra vital than getting your public-facing web site up and operating once more, as one other assault will solely take you again to sq. one (or worse).

4. Misplaced Time and Cash

Repairing an internet site that has been topic to a DDoS assault takes time. It may well additionally take cash. Should you don’t know what’s occurred to your web site and haven’t ready for the opportunity of an assault, you can find yourself having to rebuild your web site from scratch (I’ve seen websites the place this has occurred). Should you didn’t take a backup of your site, what are you going to restore it from? And when you don’t repair it rapidly, the assault might have a long-term impression in your web site’s website positioning and enterprise efficiency.

Whereas the location is down, you can be dropping cash in income, particularly in case your web site is an e-commerce store. And you could have to pay cash to rent a safety skilled or net envelope to rebuild your web site and be certain it’s protected against future assaults.

All of this emphasizes how vital it’s to defend your web site from DDoS assaults. I had one shopper who suffered frequent tried assaults due to the character of their enterprise; as a result of we arrange safety measures, these by no means impacted the location. Should you’re ready, then a DDoS assault shouldn’t have an effect on your web site both.

What Can Make Your Web site Susceptible to DDoS Attacks?

Some websites are extra weak than others to DDoS assaults. These will both make you extra weak to the assault within the first place or to its after-effects.

Low cost Internet hosting

The primary perpetrator when it comes to vulnerability to DDoS assaults, as with all types of cyberattacks, is low-cost internet hosting. Low cost internet hosting has two major downsides: lack of help and quantity of purchasers.

To make it potential to provide the internet hosting so cheaply, the internet hosting supplier could have a big number of clients all using the same server, which means if one of many different websites on that server is topic to an assault, it might have an effect on you.

Low cost internet hosting suppliers received’t present safety precautions in opposition to DDoS assaults, they received’t warn you when an assault takes place, and they received’t enable you to restore your web site when it stops working. They received’t take common backups of your web site and even when they do, they’re unlikely to enable you restore your web site: you’ll have to work out how to do it your self.

This isn’t as a result of low-cost internet hosting suppliers are attempting to con you or as a result of they don’t present the services they promise: it’s simply because to make their hosting cheap, they have to skimp on support. In any other case, they wouldn’t make a revenue.

In case your web site helps a enterprise or any enterprise the place your popularity and the safety of your web site are vital, then it pays to put money into good high quality internet hosting. The additional value can be price it whenever you keep away from having to spend time fixing your web site whether it is attacked, and will definitely be price it if it means your web site stays on-line via an tried DDoS assault and isn’t compromised.

Lack of Preparation

Failing to put together for the opportunity of a DDoS assault received’t essentially forestall one from occurring, however it can imply you don’t undergo a lot if you’re topic to one.

Firstly, taking safety precautions in opposition to potential assaults will improve your web site’s probabilities of staying on-line regardless of struggling an tried assault.

However understanding how to cease a DDoS assault in its tracks will even assist. In case your web site is attacked and does go down when you’ve ready it is possible for you to to get it up and operating once more a lot faster than when you hadn’t ready.

Installing security software or making use of the safety alerts provided by your internet hosting supplier means you can be alerted in case your web site does come underneath assault, and both you or your internet hosting supplier can take motion to defend your web site.

Taking regular backups of your web site means which you can rapidly restore it if it does expertise issues.

And holding your site up to date implies that it’s inherently safer and can be much less probably to encounter issues when you do have to rebuild it.

Insecure or Out of Date Code

Preserving your model of WordPress in addition to your theme and plugins up to date received’t defend you from a DDoS assault.

However if you’re attacked and the following weak spot of your web site is utilized by hackers as a possibility to achieve undesirable entry, they are going to be far much less probably to succeed in case your web site is nicely managed.

Precautions embody holding your web site up to date in addition to solely putting in plugins and themes from respected sources. The WordPress theme and plugin directories are by far the very best locations to discover free themes and plugins, and respected builders will make them accessible there. Watch out not to set up code which may trigger incompatibilities along with your internet hosting and by no means set up nulled themes or plugins.

How to Protect Your Site In opposition to DDoS Attacks

So now for the query you’ve been itching to know the reply to: how do you defend your web site in opposition to DDoS assaults? There are a number of precautions you possibly can take, and which you select will rely in your setup, your price range, and your preferences. Let’s check out the choices.

Safety from Your Internet hosting Supplier

Right here comes the exhausting fact, although: nevertheless good your internet hosting supplier is, it’s not possible for them to present whole safety in opposition to DDoS assaults. What a very good internet hosting supplier will do is present a very good firewall, which is able to scale back the possibility of an assault however not eliminate it altogether. They will even have instruments you or they will use to cease the DDoS assault as soon as it begins, reminiscent of IP blocking.

Because of this any internet hosting supplier that claims to provide you with whole safety from DDoS assaults isn’t being completely trustworthy. They will scale back the likelihood of an assault and they will restrict the impression of it, however they will’t cease DDoS assaults completely.

As an alternative, to defend your self from DDoS assaults extra completely you want to use an enormous community that may use its database of details about assaults on different websites around the globe to anticipate assaults and block IPs from which they’re probably to come. Let’s have a look at a few these providers.


Cloudflare is among the web’s hottest suppliers of content delivery networks, and it additionally provides safety in opposition to assaults and hacks. Due to its huge dimension, it has entry to details about the place DDoS assaults are coming from and can then block these IP addresses for all of the websites on its community.

Cloudflare’s cloud-based community is at all times on and at all times studying, which means it may be figuring out potential assaults and cease undesirable site visitors from reaching your web site 24/7. It additionally supplies you with a dashboard you need to use to monitor and allay DDoS assaults so you possibly can establish what your vulnerabilities is perhaps.


Sucuri is an organization greatest recognized for its providers cleansing up websites after hacks and serving to to forestall them from occurring once more. Nevertheless it additionally provides DDoS safety.

Sucuri’s service works as a result of it’s so giant, with a community of over 400,000 clients which means it will probably maintain a database of assaults in the identical manner that Cloudflare can. These IP addresses can then be blocked in your web site.

Sucuri’s community isn’t as huge as Cloudflare’s however the firm is price contemplating when you additionally need superior safety features and monitoring, which is the place their specialty lies. Sucuri will monitor your web site for downtime and assaults or hacks and will repair any hacks that happen.

So when you do undergo a DDoS assault and your WordPress site is hacked when it’s vulnerable, being with Sucuri means you may get it up and operating once more as rapidly as potential.


DDoS assaults have gotten extra frequent and they’ve the potential to trigger billions of {dollars} price of harm.

It’s not possible to utterly defend your self from DDoS assaults as there isn’t a lot management you’ve gotten over the site visitors coming to your web site. However when you use one of many providers above, keep away from low-cost internet hosting, and put together your self for a DDoS assault if one does happen, then you can be a lot much less probably to undergo.
