There are several good reasons to invest in DDoS Protection. While there is no 100% guarantee against an attack, a well-defended network can certainly reduce the effect and hopefully prevent further damage. DDoS is short for "denial of service." A DDoS attack occurs when someone causes an unusually large number of queries to Internet resources, causing the website or server to respond slowly or not at all. DDoS can be done for many reasons, but the main purpose is to bring down a website temporarily or stop the server from functioning altogether.
Many companies have moved their websites to the cloud because of the many advantages it offers. Cloud servers offer many benefits including reduced costs and much lower maintenance requirements. One of the main reasons that websites move to the cloud is to eliminate the need for maintaining physical servers and data centers, although some businesses also choose to move servers to the cloud for DDoS protection. If you're an IT department looking to hire a provider of DDoS protection, you'll want to keep these three considerations in mind.
One of the best ways to provide DDoS protection is through a provider with a large enough DDoS database to be able to respond to sudden onslaught of web requests. DDoS Attack logs usually contain thousands of IP addresses along with details about the client behind each attack. With the biggest DDoS providers, it should be possible to quickly analyze attack patterns and determine which of your sites has been affected. As an additional measure, many providers will also offer DDoS test services so you can determine what parameters will best stop an attack. For example, if a DDoS is detected on a particular site, the provider can quickly look to see if it's also being attacked on other sites.
Another consideration for your DDoS protection is preventing any further attacks from occurring in the first place. DDoS attacks typically target one or more IP addresses within a network. To prevent that from happening, you need to have a policy for blocking or limiting usage of certain IP addresses. For example, if you're a web hosting provider, it's likely that you'll want to block any clients who are trying to access your server from certain locations. This is typically referred to as "dns locking."
Once you've determined that you need to implement DDoS protection, you need to consider the underlying cause of the attack. Common causes include lag issues, malicious software, and network traffic flooding. In order to stop an attack before it begins, you should have a plan in place for mitigating any of these factors. Lag issues refer to any time during the day when your network traffic is too high to reliably transfer data to and from your servers. In addition, malicious software such as viruses or worms could be installed on your system that would cause data loss. Network flooding happens when hundreds or thousands of people connect to your network at once causing large amounts of network traffic.
If you use a cloud-based service for DDoS protection, you may be able to avoid some of these issues if you're willing to pay for a DDoS defense system that works on real-time conditions. One option is virtualization, which provides the application virtualization layers necessary to protect your application in the event of a DDoS attack. Another option is cloud networking, which emulates different server technologies so that if one fails, your others still continue to operate. Most cloud providers also provide DDoS attack mitigation services through application security and monitoring.
The key to preventing or mitigating any future attacks knows what causes them. By having a detailed understanding of why people are attacking your sites, you can avoid the causes of attacks. Some common reasons that attacks occur include malicious software, internet traffic flooding, or other unexpected events that cause data loss. To protect your network from malicious software such as viruses and botnets, you must run a program that continuously monitors for these threats and prevents them before they cause damage. Similarly, if your internet traffic floods your site, you must stop sending traffic to those sites until the problem is fixed.
In addition to running the program that stops DDoS attacks, you must also protect your website from outside attacks. One way of doing this is by using content filtering to prevent DDoS attacks from external sources. Some of the best DDoS protection systems will identify malicious scripts and warn users about them. They can also block suspicious email attachments and flag spam e-mails. Finally, by allowing the best DDoS protection network to monitor the activity on your website and send you alerts if there are problems, you will be able to quickly fix any problems that may arise.
