S Protection, the Silver Award winner; and Arbor Cloud, the Bronze Award winner. Here’s more on choosing a provider to meet your needs, along with details on how we arrived at our ranking of these 1. According to top distributed denial of service (DDo. DDoS, or distributed denial of service, is an attack where multiple compromised systems are used to target a single system causing a DoS attack. How DDoS Detection and Mitigation Can Fight Advanced Targeted Attacks SEPTEMBER 2013 A SANS Whitepaper Written by John Pescatore Attacks Grow in Complexity PAG E 2. Using a DDOS Program for the purpose of a Denial of Service Attack is extremely dangerous. Please read this prior to use of any software. Share What Is the Best Way to Respond to a DDoS Attack? A record-breaking distributed denial-of-service (DDoS) attack Monday peaked at 400 Gbit/s, which is about 100 Gbit/s more than the largest previously seen DDoS attack. S) protection service providers, DDo. S attacks are on the rise and costing companies more than ever. But what is DDo. S and what does it mean? You've heard of certain famous cyberattacks; remember when Play. Station and Xbox were down during Christmas 2. Many of the most infamous hacks in computer history were caused by DDo. S attacks. When a DDo. S attack happens, a hacker is deliberately trying to crash someone's network, website or specific network component, like a router. The reasons behind these attacks vary. Some are caused by hacker activists or . There have been cases where competing companies have sabotaged one another to undermine customer confidence, damage a company's brand and drive traffic to their own site. DDo. S attacks contribute not only to huge financial losses, but losses in customer loyalty. Imagine having the power to bring your competitor's business to a screeching halt. In order to prevent an attack, many corporations, especially ones that rely on network traffic and ecommerce, are increasingly turning to DDo. S protection services. Some companies only call these protection services when they are under attack, but in today's world with ever- increasing threats, the smartest defense is to protect your network from troublesome hackers and malicious attacks before the threat becomes real. How Does DDo. S Work? A DDo. S attack is one of the most complex threats your business can face. And it's so complex because there are several categories of DDo. S attack methods; each category has a whole host of specific attacks. The above table shows some of the common attacks used by hackers and their respective category. The goal of a DDo. S attack is to shut a business down, which is commonly executed by overwhelming or exhausting the company's network or website. Volumetric Attacks. One form of attack is a volumetric attack, which sounds exactly like what it does: It overwhelms a website or network with a flood of traffic, creating enough volume to destabilize a network's bandwidth or crash a site. The easiest way to think of this type of attack is to imagine a traffic jam: The roads are so congested you can't even move. With a volumetric attack, a hacker is sending so much traffic, it overwhelms the server. This does damage in two ways: One, legitimate traffic can't reach your site, and the company loses customers, potentially damaging your brand forever. Two, ecommerce shoppers cannot get through to purchase goods, costing your company thousands in revenue. A common deployment method for a volumetric attack is a botnet, or zombie army. A botnet consists of thousands of computers that have been hacked and are being used without owners' awareness. The hacker seizes control of the infected army of computers and directs them to assault the desired target. If thousands of computers and even hundreds of thousands are all trying to access the same site at once, relentlessly submitting requests, that can crash the system, causing a DDo. S outage. To ensure your computer isn't drafted into the zombie army, installing antivirus software can detect bot activity and sweep your system. Also, be mindful of malware, as hackers often use malware, tricking you so they can control on your devices. To find the right kind of software for your computer, check out our reviews on antivirus software. We also have more articles about DDo. S Protection Services in our learning center. Application Layer Attacks. The internet is based on seven vertical layers; each layer uses certain protocols to transmit information and traffic up the chain, which is why attackers want to target various protocols and layers of the open system interconnection (OSI) model. The seventh layer processes SMTP and HTTP communication, which manages web browsers and email services, among other programs. Application layer attacks use the seventh layer to target the application interface by mimicking real or human behavior. These type of attacks are hard to detect, are more sophisticated and are gaining in popularity than other types of DDo. S attacks. The goal of an application layer attack is not to overwhelm resources with a flood of requests, but rather to exhaust resources by consuming too much. Industry research shows, starting in 2. These attacks are stealthier and harder to detect than other methods hackers use to cripple networks. Protocol Attacks These attacks are designed to consume server resources and those of other communication devices. These attacks operate by sending a barrage of open requests, which servers and other communication devices answer and then wait for a packet response. The requests are generated by fake IP addresses, so when your devices query back, it never goes anywhere. This causes the devices to have open resources, with less availability to answer real requests. If your servers are busy answering bogus requests, they don't have the capacity to respond to legitimate traffic. Using protocols like TCP/IP, attackers use a flood of requests that effectively shut down your network resources. Why Does My Business Need Protection? Market research indicates that DDo. S attacks are becoming more popular and more sophisticated. The easier a target you appear to be, the more likely it is that at some point you and your website can fall victim to hackers. Just as you wouldn't wait for your house to be on fire to install a smoke detector, why wait for your business to be attacked before installing DDo. S security? Now that you know the basics of a DDo. S attack, you can see the dangers in operating your business online without protection. If you run a site dependent on traffic or ecommerce, it's essential that your services be available to consumers 2. Therefore, being proactive about security could save you thousands in lost revenue and protect the invaluable asset of a good reputation. How to Protect Your Business. You probably want to know how to prevent DDo. S attacks. It's important to note that attacks are increasingly more sophisticated, and malicious actors are never going to stop engineering new ways to steal or corrupt online resources or data. You are never going to be 1. DDo. S protection from industry leaders who work every day to track and combat new threats; some services guarantee 1. In addition to DDo. S protection, it's important to cover your other bases, especially with employee security training. Teaching your staff what DDo. S attack traffic patterns look like and how to respond to them when you are under attack can be extremely helpful in lessening the effects of an attack. That said, there are a variety of methods to mitigate and prevent DDo. S attacks, most of which employ some form of traffic re- routing. Threat mitigation and protection comprises three parts: infrastructure, methodology and deployment. Think of this model in the following way: If a provider has the methods to defend you from an attack but no infrastructure to support its resources, then the provider can't really use the methods. Further, if a provider has both the methods and infrastructure, but they can't effectively deploy technologies, then none of these methods help you when you need it most. The takeaway here is that you need a provider who can accommodate all three protection layers. They need to have a strong, fortified network that can handle incredible bandwidth and traffic, a variety of protection methods to suit your business network and site design, and fast, responsive deployment techniques customizable for your particular needs. One important thing to consider is customization and scalability. As your business grows, your resources will likely grow as well, which means you could outgrow your original protection model. So you need to customize your service. It also means that as you grow, the cost could become greater, so it's important to opt for a service offering scalability payment models. Infrastructure The first important aspect of a service provider's threat mitigation and protection ability involves infrastructure; specifically, the provider's capacity to detect and filter traffic. The greater the capacity, the more effectively the service can mitigate an attack. Several components contribute to capacity. Network capacity speaks to the total network bandwidth. Scrubbing capacity refers to the total bandwidth dedicated to cleaning traffic. That's an important difference. Think of it like a person's strength; you might have strong muscles, but how much of your strength are you using to lift a heavy object you don't normally lift regularly? The difference is fine, but relevant. Data centers, also known as security operations centers (SOCs) are also important for infrastructure capacity. SOCs are scattered globally and use software and hardware as well as trained, skilled technicians to constantly monitor and scrub infected traffic. These data centers are the core of a service provider's ability to detect and stop a DDo. S attack. The more SOCs and the more globally diverse or spread out they are, the better. The geographic location of the SOC matters, because depending on traffics' origin, the farther the traffic has to travel, the slower the response may be, so having data centers spread out across the world ensures fast traffic optimization, monitoring, detection and mitigation. Location matters for another reason as well, redundancy, or in this case, a backup system that is in place should the primary one fail. Normally, this term has a negative connotation, but in the case of security, redundancy is crucial.
