What are the benefits of Anti DDoS Pro CDN and what attacks can it prevent

Hello, you can protect against flood attacks, etc.

Anti-DDoS Pro CDN is adjusted according to the service type and attack problem. Anti-DDoS Pro is the default defense mechanism.

Anti-DDoS Pro servers use stand-alone defense or cluster defense, and attacks are directly hit on the source server. Anti-DDoS Pro can spread these attacks to each node, reducing the pressure of DDoS attacks to a low value.

The anti-DDoS service is to deploy a hardware firewall in the computer room to protect it through simple traction, and the traffic is concentrated in one node; Anti-DDoS Pro CDN can be used to allocate multiple Anti-DDoS nodes, which has a significant effect, and Anti-DDoS Pro CDN can hide the source server IP to improve the response speed of the first year.

Kuku cloud server for you to answer sincerely, the choice of server tenants, Kuku cloud is trustworthy.

Anti-DDoS Pro and CDN defense have some differences in defending against DDoS attacks, which are mainly reflected in the following aspects:

Deployment location: Anti-DDoS Pro servers are usually deployed in the data center or cloud platform where the target server is located to directly protect the target server from DDoS attacks. On the other hand, CDN (Content Delivery Network) is a network architecture that distributes content to multiple edge nodes around the world, and its edge nodes can also provide a certain degree of DDoS protection.

Protection scope: Anti-DDoS Pro directly protects the target server through technical means such as traffic filtering and IP blocking, and processes all traffic. On the other hand, CDN defense focuses on processing static resources (e.g., e.g., etc.) of the application and caching these resources to edge nodes closer to the user, thereby reducing the load on the origin server.

CDNs are relatively weak in protecting against dynamic requests.

Caching and load balancing: CDNs provide content distribution services and also provide caching and load balancing functions. Due to the wide distribution of CDN edge nodes, static resources can be cached, and the nearest edge node can be selected to provide services based on the user's geographical location.

This helps to improve the loading speed and stress resistance of the **.

Defense strategy: Anti-DDoS Pro server mainly uses defense strategies such as traffic filtering, IP blocking, and intrusion detection, and is a solution specially designed for DDoS attacks. CDN defense usually has some basic DDoS protection mechanisms on edge nodes, such as morning sock traffic limiting, IP blacklist and whitelist, etc., but its main purpose is to provide content distribution services, and the defense strategy is relatively simple.

To sum up, both Anti-DDoS and CDN defense can provide a certain degree of DDoS attack protection capabilities, but Anti-DDoS Pro is more focused on directly protecting the target server and providing comprehensive protection functions.

CDN defense mainly focuses on content distribution and caching, and its protection capabilities are relatively weak, which is suitable for the protection and load balancing requirements of static resources. In actual use, the advantages and disadvantages of the two can be considered comprehensively according to specific needs and the appropriate solution can be selected.

Anti-DDoS server mainly refers to an independent single hard defense server with more than 50G, which can provide security maintenance for a single customer. To put it simply, it is a server type that can help **denial of service attacks, and regularly scan the existing network master node to find possible security vulnerabilities, which can be defined as Anti-DDoS Pro servers.

Anti-DDoS Pro server defense mode: Anti-DDoS Pro server uses stand-alone defense or cluster defense, and attacks are directly hit on the source server. The attack may cause the bandwidth CPU memory usage of the server to run to 100%, and may even directly affect the origin server, resulting in problems such as stuck, unopenable, and inaccessible.

What Is the Difference Between Anti-DDoS Pro Server and CDN Defense? Which is better to use?

CDN defense is to add a new layer of network architecture to the existing Internet to publish the best content to the network closest to the user"Edge"It enables users to obtain the content they need nearby, solves the problem of Internet network congestion and DDoS attacks by peers, and improves the response speed of user access.

CDN defense mode: CDN adopts multi-node distribution, which can solve the access speed of users on different networks in various regions, solve the concurrency to reduce the pressure on the server, and hide the IP of the origin server, so that the attacker can not find the IP of the origin server, and cannot directly attack the source server, so that the attack hits the node of the CDN.

CDN Each node is a stand-alone defense, and each node has a corresponding defense of **defense, unless the attack exceeds **defense, otherwise ** will not be affected, and it can be guaranteed for the customer's **.

Anti-DDoS server is also a commonly used device for Qihe hunger users, but which one needs to be selected according to the user's actual needs, and the one that suits you is the best.

Anti-DDoS Server and CDN Defense have their own advantages and disadvantages, and have different protection effects in different situations, which comprehensively solves the problem of slow response speed of user access caused by small network bandwidth, large user access, and uneven node diversion from a technical point of view.

**Server can not avoid encountering attacks, many webmasters will** do a good job of **protection before going online**, and how to choose the protection, use anti-DDoS server or anti-DDoS CDN, and what are the differences?

Before choosing Anti-DDoS Pro, you must first understand the attacks, and the more common attacks are CC and DDoS attacks.

CC attack: CC is mainly used to attack the page, the principle of CC attack is that the attacker controls some hosts to send a large number of packets to the other party's service sedan car without stopping, causing server resources to be exhausted, resulting in a waste of server resources, and the CPU is in place for a long time.

at 100%.

DDoS attacks: Traffic attacks, which occupy a large number of network resources through a large number of legitimate requests to achieve paralysis.

Disabling the network for the purpose.

After a simple understanding of these two types of attacks, we know that defending against traffic attacks requires large bandwidth and hardware firewalls to scrub traffic, while CC attacks require policies to intercept them.

The protection mechanism of the anti-DDoS server room is fixed, and there is no problem in protecting traffic attacks, but it is very difficult to protect against large-traffic attacks, and in the face of changeable CC attacks, the defense effect is even more unsatisfactory.

Anti-DDoS CDN distributed protection mechanism, multi-node diversion anti-attack, reduce the amount of attack, improve the defense effect, CC attacks have different attack methods according to different **, before there is no CC attack, the default CC protection strategy is used, when there is a CC attack, according to the CC attack mode, formulate CC strategy to improve the protection effect.

It is recommended to use Anti-DDoS Pro CDN to hide the source IP address of the server as a stand-in. Test it for free.

Anti-DDoS Pro has several advantages:

Multi-node, intelligent switching, a high-defense node is attacked and killed;

Cache files, unable to directly attack the origin server, the origin server is less affected;

The traffic is on the Anti-DDoS Pro CDN, and the server bandwidth demand is reduced;

Generally speaking, the Anti-DDoS Pro server is much more expensive than the Anti-DDoS Pro CDN, because a CDN server can place many customers, as long as the configuration is good enough. In fact, ** protection also depends on the specific situation. Anti-DDoS Pro Server and Anti-DDoS Pro CDN have their own characteristics and advantages.

If your site doesn't have a lot of traffic and the stability requirements are not very high, you can use Anti-DDoS Pro server. However, for a large number of users and high speed requirements, it is recommended that you use Anti-DDoS Pro CDN.

Suggestion: Yousu CDN, they **2000 yuan a month. The maximum protection is 100G, and I believe that most attacks can be easily handled.

CDN stands for ContentDeliveryNetwork. That is, a content delivery network. The basic idea is to avoid the bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make the content transmission faster and more stable.

By placing node servers in various parts of the network to form a layer of intelligent virtual network on the basis of the existing Internet, the CDN system can redirect the user's request to the nearest service node to the user in real time according to the network traffic and the connection of each node, the load status, the distance to the user and the response time.

If the Anti-DDoS Pro CDN is attacked and killed, you can switch nodes, which is better than the Anti-DDoS Pro server.

3 All CDN is a new type of network construction method, N is built on the basis of the existing network on the basis of the intelligent virtual network, relying on the edge servers deployed in various places, through the load balancing, content distribution, scheduling and other functional modules of the central platform, so that users can obtain the required content nearby, reduce network congestion, improve user access response speed and hit rate. The key technologies of CDN mainly include content storage and distribution technology.

To put it simply, the main function of CDN is to accelerate, but in addition to providing access speed, CDN also has defense functions, so there will be anti-DDoS Pro. The widely distributed CDN nodes and the intelligent redundancy mechanism between nodes can effectively prevent hacker intrusion and reduce the impact of various DDoS attacks on the best of the best, while ensuring good service quality.

It's not simple.

1. The principle of Anti-DDoS Pro CDN is to set up multiple Anti-DDoS Pro CDN nodes, and when there is a CDN node attack, each node will bear it together. It will not be inaccessible because a node is killed by an attack.

2. If there are 4 or even 10 more nodes in the protection of the anti-DDoS CDN, it is impossible for each node to attack, or even kill the nodes at the same time. That's the value of Anti-DDoS Pro CDN and its benefits over standalone Anti-DDoS servers.

3. Of course, the high-defense CDN is only suitable for ** applications, like a lot of games, it is basically not good, which is also his weakness.

4. Building a high-defense CDN is not simple, and requires a large amount of server investment and a large amount of bandwidth support.

First, the Hong Kong Anti-DDoS server can provide users with security maintenance, and through the hardware firewall, it can effectively defend against DDoS traffic attacks and DOS traffic attacks. The defense mode of the Hong Kong Anti-DDoS server is stand-alone defense or cluster defense, and the attack directly attacks the source server. An attack can cause the server to run bandwidth CPU memory usage up to 100%.

It may even directly affect the origin server, and the result will be stuck or unable to open and access.

Second, the CDN can hide the IP address of the origin server, and even if it is attacked, it is only a CDN node, so the origin server will not be affected, and the CDN protection is more active than the Anti-DDoS Pro server.

Third, the defense mode of Anti-DDoS Pro CDN adopts multi-node distribution, which solves the difference in access speed of users in different regional networks, solves the problem of concurrency, reduces the pressure on the web server, and hides the IP of the origin server, so that attackers cannot directly discover the IP of the origin server and cannot directly attack the source server, so as to attack the high-defense CDN node. The high-defense CDN node is a stand-alone defense, and each node has a corresponding packet defense defense, which will not be affected unless the attack is over-packet defense, which can provide security for customers.

Fourth, Anti-DDoS CDN defense adds a new layer of network architecture to the existing Internet, publishing the best content to the nearest network "edge" to the user, so that users can get the content they need as soon as possible, avoiding the congestion of the Internet network and the problem of peer-to-peer DDoS attacks. Accelerate responsiveness to consumer access**. Technically, it comprehensively solves the problem of slow response caused by factors such as small network bandwidth, large user access, and uneven node distribution.

At present, the DDoS attack traffic is getting higher and higher, often hundreds of Gigamigabytes, and it often occurs that it exceeds T during peak hours, network security needs to be paid attention to by users, and the cost of hardware defense of Anti-DDoS server is very high. If there are frequent low-traffic attacks, the Anti-DDoS Pro server will be more suitable, and if the IP of the server is easy to hide and the attacks are not very frequent, CDN protection is more effective.
