How should Anti DDoS Pro servers be defended?

1.Regular seedling sweeping server;

2.Configure firewalls on the backbone nodes of the server;

3.Enough machines to withstand hacking;

4.Make full use of network equipment to protect network resources;

5.Overthink unnecessary services and ports.

Nowadays, the vast majority of Anti-DDoS servers on the market mainly help users defend against various network attacks and maintain the security of the server itself by implementing protection at the "network level" and "physical level".

1. Network defense.

There is a type of Anti-DDoS server, which is mainly a server that strengthens the network defense. This kind of high-defense server is the same as an ordinary server in terms of hardware, but in terms of technology, a special IP hiding design is carried out, so that external attacks cannot directly attack the server, which is also a very effective defense measure and principle.

2. Physical defense.

Generally speaking, the high-defense servers we usually come into contact with refer to physical defense, that is, adding a layer of hardware firewall directly on top of the server's hardware. Such a hardware firewall is undoubtedly like a heavy layer of "armor" of the server, which can play a very good defensive role. Therefore, the default Anti-DDoS Pro server is this kind of Anti-DDoS Pro server that adds a "hardware firewall" for physical defense.

This kind of high-defense service can make users enjoy a safer, better and significant defense effect through the blessing of physical hardware.

Let's teach a few tricks how to distinguish the good from the inferior high-defense server (server)!

1. Look at the bandwidth of the computer room.

Most local network attacks use bandwidth-consuming attacks, so the data center needs to provide enough bandwidth to deal with bandwidth-consuming network attacks, so users can judge the advantages and disadvantages based on the bandwidth provided by the data center.

The BLU Cloud has three major computer rooms: China Telecom, China Unicom and Mobile, among which the telecom computer room is the only national-level standard diamond four-star computer room in Yunnan, providing 7*24 hours of discontinuous computer room service.

2. Look at the defense ability of the firewall in the computer room.

Generally speaking, data centers that provide high-defense servers will be equipped with firewall equipment, and ordinary equipment must be at least 100G or more. Users need to understand how strong the defense of the firewall and stand-alone machine is in the computer room, and understand whether it can be upgraded to a higher level of defense at any time according to the needs.

3. Look at the brand of the server in the computer room.

Local network attacks use resource-consuming attacks, and after a large number of attack packets, the server memory, CPU and other resources are disintegrated, so the high-defense server must use well-known brand servers, so users need to carefully choose other unknown brand servers.

4.Look at the line of the servicer.

In several major lines in China, the protection strength of telecommunication lines is the strongest, and other lines can not be compared with telecommunication lines, so when choosing a domestic high-defense service device, the choice of high defense service device of the telecom line is the best, if there is no telecom line, it can sweep away this company.

5.Test the Anti-DDoS Pro IP band for yourself.

The most direct way to distinguish the advantages and disadvantages is to go to the scene and directly stop the test on the high-defense IP band, so that you can know whether it can defend the real and whether its defense can reach its own request.

What should the server do to defend itself? Cool Cloud is here to teach you.

Some common server attacks, such as Trojan viruses, can be solved through ordinary security maintenance and firewalls, while general server attacks, such as DDoS attacks, CC attacks, and ARP spoofing, can be solved. This attack cannot be prevented, and only by using DDoS Cloud Protection can it be effectively prevented.

So, let's talk about the means of server attack prevention. Method 1: Use Cloud DDoS protection.

Traffic attacks are usually a very brutal tactic that consumes bandwidth or consumes server resources or constantly requests servers to bring down servers so that they don't function properly. When faced with such an attack, only DDoS Cloud can prevent this attack and direct the attack traffic to the Anti-DDoS Pro node to ensure that the origin server does not receive the impact of the attack. Method 2:

Routine safety maintenance. Another common type of server attack is that it is infected with a Trojan virus and so on. The best way to prevent such attacks is to open the firewall on a daily basis, check logs, install security dog software, patch vulnerabilities, and so on.

As long as there is a dual guarantee of DDoS cloud protection and daily security operation and maintenance, the server has basically been protected against attacks, and the security is relatively guaranteed, and it will generally not be affected by attacks. At the same time, you should also keep a normal mind, cyber attacks will occasionally be encountered, as long as you can actively deal with and solve them, there will be no problem, instead of blindly blaming the service provider for not giving the server to the force.

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

The use of Anti-DDoS server, Anti-DDoS Pro IP (DDOS defense), and Anti-DDoS CDN can prevent network attacks, including but not limited to defending against DDoS, CC and other attacks.

The highest single point of Espeed Cloud can defend against 1000G DDoS traffic attacks, and 5000G DDoS traffic attacks are globally distributed, covering China Telecom, China Unicom, China Mobile, Hong Kong CN2, the United States and other countries and regions.

1. If you want to intuitively identify the authenticity of the Anti-DDoS server, you can directly ask the IDC service provider for the IP address of the Anti-DDoS server for process testing. Generally, the speed test of a server can be viewed by ping the command. Anti-DDoS Pro servers are generally unable to ping, so before choosing an Anti-DDoS Pro server, you can ask the IDC service provider for the IP address of the Anti-DDoS Pro server and judge through this simple test.

2. Many network attacks are bandwidth-consuming attacks, such as DDoS attacks, CC attacks, etc., and the Anti-DDoS server carrier, as a high-defense server carrier, needs to have a large enough bandwidth to withstand the attack. This is also one of the features of Anti-DDoS Server, which users can judge based on;

3. Anti-DDoS server has high requirements for the performance of the hardware firewall and the hardware equipment of the server, and generally uses brand servers, and a large number of attack packets will cause the crash of server memory or CPU, so the brand server can run more stably than the general assembly server or other servers;

4. Each anti-DDoS server data center has its own firewall system, which is not limited to the computer room of the anti-DDoS server, even if the computer room without anti-DDoS server is fully arranged, there will be a firewall system. The firewall system of the anti-DDoS server room is much stricter, especially for industries such as finance and games, especially in the stage of rapid business development.

1. Look at the bandwidth of the computer room.

2. Look at the defense capability of the firewall in the computer room.

3. Look at the brand of the server in the computer room.

4. Look at the server.

5. Test the anti-DDoS IP segment in person.

1.Anti-DDoS Pro server is actually easy to understand, that is, it refers to a single server that independently defends more than 50G. The type of server that can help resist intrusion and regularly scan the existing network master node to find possible security vulnerabilities can be called Anti-DDoS server.

2.From the perspective of defense scope, Anti-DDoS Pro server is designed to protect various types of DDoS such as SYN, UDP, ICMP, HTTP GET, etc., and can provide dynamic defense for some web users with special security requirements.

3.Since Anti-DDoS Pro is for DDoS, what is DDoS? DDoS is the use of a group of controlled machines to launch an invasion on a machine, which is highly destructive.

Syndicate actions initiated by hundreds, or even thousands, of compromised hosts at the same time are more threatening than those initiated by a single host.

There are two main forms of manifestation, one is mainly for network bandwidth, that is, a large number of packets cause the network bandwidth to be blocked, and legitimate network packets are flooded by false packets and cannot reach the host. The other is resource exhaustion, which is mainly aimed at the server host, that is, the memory of the host is exhausted or the CPU is occupied by the kernel and applications, resulting in the inability to provide network services. Either way, using a large bandwidth will prevent network congestion and resource exhaustion.

Therefore, when choosing an Anti-DDoS Pro server, you should not only look at the defense capability, but also pay attention to the size of the bandwidth.

Cyber Defense.

If you want to study in detail what the defense method of the anti-DDoS server is, then there is another kind of online anti-DDoS server that is a server that strengthens the network defense, this kind of server is the same as an ordinary server, but the design of IP concealment is technically carried out, so that the attack cannot find this server to attack, and it is also an effective defense method.

Physical defense. Generally, the high-defense servers we come into contact with are physical defense, that is, a layer of firewall is directly added to the server hardware, which is equivalent to the "armor" of the server, which can play a good defensive role.

The differences between Anti-DDoS Pro and Anti-DDoS Pro in Anti-DDoS Pro servers are as follows:

1. The high-defense server refers to the defense capability of the server itself, and the protection value is more than 10G, which is designed for a single customer to provide defense capabilities, the main working principle of high-defense is traffic cleaning, cleaning out those abnormal IPs, so that those normally accessed IPs can be accessed normally, so that the server will not be affected by malicious attacks, do not block IPs, and ensure the normal operation of the world, our most common attack is DDOS and CC.

Anti-DDoS Pro server.

2. Hard defense server (high hard defense server) is actually our common server that provides hardware defense, such as the hardware firewall and gold shield and other protection, which is to embed the software into the special hardware, and then be responsible for defense, so that its security performance and stability will be better, which is an important barrier to ensure network security, and it belongs to hardware protection. In general, its ** will be relatively higher.

When choosing a high-defense server, users can first have a general understanding of these two types of defense, so that when choosing a high-defense server, they can choose the appropriate defense according to their actual situation, and at the same time, they must also choose a reliable service provider to choose.

In addition to the above defense methods, there is also a high anti-DDN CDN, followed by traffic traction technology, which is a new type of defense, which can distinguish normal traffic from attack traffic, and pull the traffic with attacks to devices that defend against DDOS, CC and other attacks, and pull the direction of traffic attacks to other devices instead of choosing to resist by itself.
