What exactly is DDoS Mitigation?
The process of successfully protecting a targeted server or network from a distributed denial-of-service (DDoS) attack is referred to as DDoS mitigation. A targeted victim can mitigate the incoming threat by using specially designed network equipment or a cloud-based protection service.
When using a cloud-based provider to mitigate a DDoS attack, there are four stages:
Detection – In order to prevent a distributed attack, a website must be able to distinguish between an attack and a high volume of normal traffic. If a website is inundated with legitimate new visitors as a result of a product release or other announcement, the last thing the site wants to do is throttle them or otherwise prevent them from viewing the website’s content. IP reputation, common attack patterns, and historical data all help with proper detection.
Response – In this step, the DDoS protection network responds to an incoming identified threat by intelligently dropping malicious bot traffic and absorbing the rest. A network can mitigate the attempt at disruption by using WAF page rules for application layer (L7) attacks or another filtration process to handle lower level (L3/L4) attacks such as Memcached or NTP amplification.
Routing – An effective DDoS mitigation solution will intelligently route traffic, breaking the remaining traffic into manageable chunks and preventing denial-of-service.
Adaptation – A good network analyzes traffic for patterns such as repeating offending IP blocks, specific attacks coming from specific countries, or improper use of specific protocols. A protection service can harden itself against future attacks by adapting to attack patterns.
Selecting a DDoS Protection Service
Purchasing equipment that would live on-site and filter incoming traffic was the traditional DDoS mitigation solution. This method entailed purchasing and maintaining costly equipment, as well as having a network capable of absorbing an attack. A large enough DDoS attack can destroy the network infrastructure upstream, rendering any on-site solution ineffective. Certain characteristics should be considered when purchasing a cloud-based DDoS mitigation service.
Scalability – an effective solution must be able to adapt to the needs of a growing business as well as respond to DDoS attacks of increasing size. Larger-than-2-terabit-per-second (Tbps) attacks have occurred, and there is no indication that the trend in attack traffic size is decreasing. Cloudflare’s network is capable of handling much larger DDoS attacks than have previously occurred.
Flexibility – enables a web property to adapt to incoming threats in real-time by allowing it to create ad hoc policies and patterns. The ability to implement page rules and populate those changes across the entire network is essential for keeping a site operational during an attack.
Reliability – DDoS protection, like a seatbelt, is something you only need when you need it, but when that time comes, it better work. The dependability of a DDoS solution is critical to the success of any security strategy. Ascertain that the service has a high uptime rate and that site reliability engineers are available 24 hours a day to keep the network operational and to identify new threats. The platform’s strategy should include redundancy, failover, and an extensive network of data centers.
Size of the Network – DDoS attacks follow patterns that occur across the Internet as specific protocols and attack vectors change over time. A large network with extensive data transfer enables a DDoS mitigation provider to quickly analyze and respond to attacks, often stopping them before they occur. Cloudflare’s network handles Internet requests for millions of websites, giving it an advantage in analyzing data from global attack traffic.
DDoS Mitigation Solutions
DDoS Secure detects and blocks both inbound and outbound DDoS attacks in real-time. Machine learning and artificial intelligence learn normal traffic patterns, allowing for the rapid and accurate detection and mitigation of abnormal attack traffic.
DDoS Secure is capable of the following:
- Stop inbound and outbound attacks in real-time, before they disrupt network service.
- To prevent volumetric attacks, inspect all network traffic.
- Machine learning and artificial intelligence can be used to detect even unknown attacks.
- To preserve legitimate traffic and service quality, combine DDoS mitigation with DPI-based traffic management.
- You will benefit from unrivaled scalability, allowing you to mitigate even large terabit attacks from multiple vectors.
- The ERT (Emergency Response Team) is available 24 hours a day, seven days a week.
What Is the Importance of DDoS Mitigation for Your Business?
Businesses of all sizes and industries are vulnerable to DDoS attacks. Those hosting business records, customer information, or financial data are particularly vulnerable. However, with proper DDoS mitigation strategies, an organization can save time, energy, and money while ensuring effective protection.
DDoS mitigation services are intended to reduce the risk posed by the wide variety of modern DDoS attack methods that may be directed at an enterprise. They are intended to preserve the availability of resources, which attackers seek to disrupt. Attacks that affect the enterprise, the customer, or both can damage a company’s reputation and result in revenue loss.
