A Distributed Denial of Service or DDoS is a type of attack which hampers or completely prevents users from seeing or accessing your website.
A DDoS attack works by essentially overloading your system, making it difficult for your website to remain online. These attacks ramp up the number of queries requesting access to your website’s resources with the aim of exceeding the website’s capacity to handle simultaneous requests — effectively crashing the site.
This can result in a bad visitor experience or damage your reputation.
Because it’s easy to commit a DDoS attack, some attacks can be for fun or status, such as in gaming attacks between players. Unfortunately, most attacks are committed by cybercriminals with darker motives. It’s important to be aware of how DDoS could affect you.
Hackers who are cyber criminals usually have some of the following motives.
Others wish to score a political point or commit espionage to secure company secrets.
Any small business or website owner can suffer a DDoS attack but the most common targets by industry are
Being aware of DDoS helps you prepare in advance so you can stop attacks before they happen.
Attacks can last for days, or even weeks and the threat is especially concerning for e-commerce websites if all at once, the devices under the control of the attacker send requests for your web resources, overwhelming your webservers, slowing or crashing your site.
When customers can’t purchase from the website or receive assistance, they might not return.
The tech know-how isn’t complicated for the hacker. It’s easy to mount an attack.
DDoS attacks are popular because attackers only need to gain control of a number of machines and create a zombie network. Any device within the Internet of Things (IoT) such as printers, personal computers, webcams, and even microwaves can be part of this.
You’re vulnerable to DDoS hacks and data breaches if your company has a skills gap in securing sensitive information, as

lost productivity, and in costs dealing with the after-effects of data breaches.
Keep in mind trust is king online. It’s hard to say what the cost is to your reputation.
Many say it’s only a matter of time before hackers will knock at your website’s door.
There are many DDoS attack styles and they vary in complexity. A DDoS attack will either
How your servers are compromised depends on which attack vector is chosen.
One step at a time. It’s important to think of DDoS as an attack requiring a point of entry, and once you’ve got a breach, the next phase is a tidal flood of queries, followed by data theft.
You need simultaneous services to both eliminate a hacker’s ability to mount a DDoS on your doorstep and absorb a flood of queries if there’s a breach.
You can secure your uptime and information before an attack with high-grade DNS services and a CDN. This can be through a Managed Service Provider (MSP) or a service you buy through a registrar (like Namecheap).
DDoS hackers can target the transport layer (layers 1-4) of the operating system of the Internet (OSI). This operating system tells every byte of data where to go and how to travel. Transport layer attacks may target your DNS. The second entry point involves layers 5-7, where zombie botnet attacks flood your server (the target) with queries.
Don’t wait for hackers to shut down all your connected Internet devices and overwhelm your website’s bandwidth. It’s important to secure every layer of the OSI system — and you can!
Reject the queries
A CDN hides your origin address, making it impossible for attackers to Identify your origin nameserver and hijack your bandwidth. Now that your IP is not visible in HTTP GET and POST headers (L5–7), you can avoid query floods when you set your CDN to identify and filter suspicious traffic. This keeps legitimate traffic flowing to your website
Absorb an attack
You can prepare in advance for breaches at the DNS layer (L4). A service such as PremiumDNS disperses requests using powerful Anycast global servers — 30+ edge server nodes. The network can handle large DNS query volumes—no worries. This gives you time to fix your system server or wait for the server owner to mitigate the attack — known as DDoS mitigation — and you can stay online.
Distribute your content
When you deploy Supersonic CDN your website is distributed globally. Think of this as spreading your content over a wider surface. A DDoS targets a particular server with content queries; but you have alternative servers making sure your content is still available during the attack. You won’t lose customers, and you have time to re-route traffic around the struggling server.

CDN stands for Content Delivery Network. A CDN is a group of distributed servers around the world that cache (store) and deliver assets (like images and video) to your website visitors more quickly, no matter where they’re located. In addition to faster website loading times, a CDN also secures your website, protecting it from DDoS and/or cyber-attacks.
The Domain Name System (DNS) is used by computers to translate web addresses, or Uniform Resource Locators(URLs) into a string of numbers known as Internet Protocol (IP) addresses. When you type a URL into your web browser, your browser uses IP numbers to track down the site’s DNS records. Then, the DNS performs a whole series of operations to retrieve the website for you. In the final step, the DNS switches the IP address of the website you were seeking back to its domain name. Impressively, in fractions of a second, the website appears on your screen.
