How to deploy DDoS high protection? Detailed explanation of the operation steps of the whole process

With the rapid development of Internet services, the frequency and intensity of DDoS attacks continue to rise. Once a large-scale attack occurs, the enterprise business system may be paralyzed, causing serious economic losses and brand impact. DDoS high-defense is the core means to resist such attacks, and the professionalism of its deployment directly determines the protection effect. This article will dismantle the deployment points of DDoS high-defense in detail for you, and help you build a solid business protection barrier.

What preparations should be made before DDoS deployment?

before the formal deployment of DDoS high defense, adequate preparation is the basis for ensuring the protection effect, which can avoid subsequent problems of protection dislocation or waste of resources.

1, traffic and attack

first need to sort out the daily traffic peak, port usage, core business node distribution of their own business, and investigate the types of DDoS attacks often encountered by similar businesses in the industry, such as SYN flood attacks, UDP reflection attacks, etc., to clarify the common peaks and characteristics of attacks, and provide data support for DDoS high-defense resource allocation.

2, network architecture compatibility

to check the existing network architecture and DDoS high-defense compatibility, such as whether the use of multi-line BGP network, whether there are third-party CDN or WAF services in parallel, to avoid the deployment of DDoS high-defense routing conflicts, traffic forwarding anomalies and other issues. At the same time to confirm the business system can be interrupted time, planning the deployment window period, reduce the impact on normal business.

2, how to choose the appropriate DDoS high anti-deployment scheme?

the current DDoS high-defense deployment scheme is mainly divided into three types, different scenarios and protection capabilities are different, need to be combined with their own needs reasonable choice.

1, cloud DDoS high anti-deployment solution

cloud DDoS high defense without the need for enterprises to invest in hardware equipment, by switching business traffic to cloud protection node to achieve attack cleaning, suitable for small and medium-sized enterprises or business traffic fluctuations in the scene, with pay-as-you-need, fast online advantages, can deal with common low intensity DDoS attacks.

2, hardware DDoS high anti-deployment solution

hardware DDoS high-defense requires the deployment of special protective equipment in the enterprise's local computer room, with stronger protection capabilities and DDoS attacks that can carry large traffic. It is suitable for enterprises with extremely high requirements for data security and protection stability such as finance and e-commerce. However, the upfront investment cost is high, and the deployment cycle is relatively long.

3, Hybrid DDoS High Defense Deployment Solution

hybrid DDoS high-defense combines the advantages of cloud and hardware protection, daily traffic through the cloud DDoS high-defense basic protection, encounter large traffic attack automatically switched to the hardware protection node, suitable for large business scale, high attack risk level enterprises, can achieve a balance between cost and protection effect.

What are the specific configuration and implementation steps of DDoS high protection?

determine the deployment plan of DDoS high defense, enter the specific configuration implementation stage, which is the core link of the protection plan landing.

1, traffic routing switching configuration

If you choose cloud DDoS high defense, you need to resolve the DNS of the business domain name to the Internet Protocol Address of the high-defense node, or route the operator to the high-defense cluster; if it is hardware DDoS high-defense, you need to access the core business traffic through mirroring or forwarding. Protective equipment to ensure that all incoming and outgoing traffic passes through DDoS high-defense cleaning nodes.

2, protection rules personalized configuration

configure personalized protection rules according to the business characteristics and attack types investigated in the early stage, such as setting the threshold of SYN packets, identifying the characteristics of UDP reflection attacks, and releasing the normal traffic of core business ports. At the same time, the intelligent learning function of DDoS high protection should be turned on, so that the system can automatically identify the characteristics of normal business traffic and reduce the probability of false interception.

3, test to verify the protection effect

configuration is completed, it is necessary to conduct simulated attack tests, such as using professional tools to launch SYN flood attacks, verify whether DDoS high-defense can effectively clean the attack traffic, and check the response speed and availability of the business system to ensure that the protection rules will not affect the normal operation of the business.

4. How to optimize operation and maintenance after DDoS high-defense deployment?

DDoS high-defense deployment is not done once and for all, continuous operation and maintenance optimization allows protection capabilities to always adapt to changes in business and attacks.

1, real-time traffic and attack monitoring

to enable DDoS high-defense real-time monitoring function, pay attention to traffic fluctuations, attack alarm information, once abnormal traffic or attack behavior is found, timely analysis of attack types and sources, adjust protection strategies. At the same time, it is necessary to regularly export monitoring reports, summarize the laws and trends of attacks, and provide a basis for subsequent protection optimization.

2, protection rules are regularly updated

With the development of business and the evolution of attack methods, it is necessary to regularly iterate the protection rules of DDoS high protection, such as the new type of attack feature library, adjusting the traffic threshold parameters, and combining the new needs of the business, such as when adding business ports or nodes, timely update protection policies to ensure that the protection scope of DDoS high protection covers all core businesses.

To sum up, the deployment of DDoS high-defense is a whole-process system from early preparation to continuous optimization. It is necessary to choose the adaptation plan in combination with the actual business, strictly implement the configuration steps, and do a good job in daily operation and maintenance. Through scientific deployment of DDoS high-defense, it can effectively resist various DDoS attacks, build a protective barrier for the stable operation of the business system, and reduce various risks and losses caused by attacks.
