it's jewelry wholesale How to resist the server by malicious traffic?

quality wholesale costume jewelry Configure the firewall at the backbone node
The firewall itself can resist DDOS attacks and other attacks. When discovering the attack, you can guide some sacrifice hosts so that the real host can not be attacked. Of course, these sacrifice consoles can choose unimportant, or less vulnerabilities such as Linux and UNIX and inherently defense with excellent attacks.
In enough machine to withstand hackers
This is a more ideal response strategy. If the user has sufficient capacity and sufficient resources for hackers, when it continues to access users and seize user resources, their energy is gradually consuming. Maybe the user has not been defeated to death. Essence However, this method requires a lot of funds. Most of the equipment is usually idle, which is inconsistent with the actual operation of the current network of SMEs.
makes full use of network equipment to protect network resources
The so -called network equipment refers to load balancing equipment such as router and firewalls, which can effectively protect the network. The router was the first to die when the network was attacked, but other machines did not die. The dead router will return to normal after restarting, and it is still fast, and there is no loss. If other servers die, the data in it will be lost, and restarting the server is another long process. Especially a company uses a load balancing device so that when one router is attacked, the other will work immediately. As a result, DDOS attacks were reduced to the greatest extent.

wholesale jewelry pallets Whether it is a small and medium -sized enterprise website or a large enterprise website, it will face the danger of being attacked. Without a professional programmer's maintenance, the website will often occur with many problems. Many customers. However, in the face of the website attack, it is not helpless and waiting for it. The website's attack just means that the website has security vulnerabilities. As long as you check the shortage and make up, you can keep the website's normal operation. There is a loophole in the website because the computer system or website program is constantly being found to be new vulnerabilities. It is not a very professional programmer to be neglected to prevent prevention, and brings some opportunities to some illegal people. To this end, the operation and maintenance of the website is not a simple matter, and it is closely related to the professional technology, management habits, and responsibility of programmers.
MST on the website of the website:
(1) Website webpage is hung up: When we open the website webpage, it will be prompted by the browser or computer security management software. The reports such as the horse are implanted in the webpage and root directory files. When the webpage is opened, the JS command is triggered, and the script or PHP file containing a Trojan horse is automatically executed, thereby stealing the user's privacy data. The attacked websites are often some websites involving virtual currencies or trading properties.

The attacked websites are widely favored by hackers.
(4) Website webpage opens automatically jump to other website pages: This form is often called an illegal bridge page, the forced transfer JS implanted in the webpage, or invading the server, which is done in IIS. 301 redirection to jump, the purpose is to benefit some illegal advertising or website weight transfer. The attacking objects are often some websites with weight and traffic.
(5) The website database is implanted with new content. Website data is implanted with some newly added content. These contents and other data of the website seem to be normal, but when you look at the time date, you will find that the content is often concentrated, not the content added by the editor. Such websites are often some websites that can apply for documents, such as vocational qualifications, graduation certificates, etc. Hackers implant false career information for some illegal customers, and obtain high benefits from them. The attacked websites are often some university official websites, education departments websites or some qualified websites.
(6) The website is not attacked and opened very slowly: the website webpage is often unavailable, or the server cannot be connected remotely. This situation is often due to fierce competition in the company. Its website programs and servers make websites or servers from running normally, such as a large number of DDOS attacks, CC attacks, direct destruction or deleting website data. Some hackers have psychological distortions and show off their abilities for malicious attacks. The attacked websites are often websites with low maintenance levels or some websites with low maintenance levels.
(7) Website and server passwords are tampered with: Sometimes the passwords of the website and server are not correct and are tampered with. It is because hackers have cracked violently on websites and servers with vulnerabilities and tampered with the password. The purpose is often to show off hacking technical capabilities and conduct malicious and illegal hacking technical operations. The attacked website is all websites.
(8) Lost or damage to the website database: Sometimes it is found that your website can be opened normally, but you cannot continue to update the program and add content. This situation is often a programs or hacks that lack professional ethics to conduct malicious attacks on websites. The attacked websites are various websites.

In this case, we ping website IP will not be your own server IP. This There is often a domain name DNS hijacking. The purpose is to malicious attacks to show off or advertising interests. The attacked website is all class websites.
(10) The website server is running slowly, and viruses are implanted in worms: Sometimes webmasters will find that the website is updated or the server operation is abnormally slow. The process of high memory. This is a checked Trojan, and often detects viruses such as worms. The purpose is to occupy website resources, or the server itself is attacked and invaded, as a platform for "meat chickens" to attack others. The attacked website is often some high -performance, high -bandwidth servers.
. How to operate and maintenance of the website server:
(1) Periodic backup of website data: regular backup website data can be used to restore the attacking websites. Restore at any time. For this websites, websites backup is the last word.
(2) Website program system update: Website program and server system regularly updated versions and patchs, which can eliminate some existing security vulnerabilities to prevent hackers from bringing opportunities.
(3) Regularly check the website virus: regularly killing the website virus can prevent hackers from further breaking or stealing the website data, or to delete the invasive website back door vulnerability file in time.
(4) Website file permissions settings: Reasonable setting permissions for website server files. For example, important files of some executions should be canceled to write or execute permissions to prevent hackers from tampering with website data.
(5) The website domain name opens the HTTPS data security transmission protocol and CDN acceleration, opens HTTPS and CND, can run the website faster and securely, you can hide your own website real IP, prevent DDOS attacks, CC to a certain extent Safety risks such as attack and domain name hijacking. How to defend DDOS attacks and CC attacks?
(6) The high imitation server can be used: the high imitation server has the characteristics of high performance, high bandwidth, and high defense. In terms of safety and operation, it has a certain basis for its own maintenance. It is convenient, but the cost is high, and customers should consider as appropriate according to their economic situation.
(7) Regularly update the management password: The website password can be recorded by the resigned programmer or the hacking of the invasion of the bruises to solve it. Regularly update the background password of the website and the remote server login password to effectively prevent data loss.
(8) Regularly check the website log: The records of the website running data are recorded in the website log. Open and check the website logs regularly, clearly the trajectory of the website operation, which is one of the important ways for website maintenance.
