1, regular vulnerability scanning, cleaned a threat
to any website in addition to possible loopholes, the will of some possibilities there are security risks. So to avoid malicious attacks, the need for regular scans of these vulnerabilities and security risks and promptly clean up. Select the rented high anti-server, service Chamber of Commerce Web site regularly for vulnerabilities deployed on the server appears to repair, some of the security risks and the possibility of the existence of timely clean-up, to avoid any opportunity for the attacker. In general, the attacker would most likely attack against backbone nodes, so the service Chamber of Commerce regularly scan the backbone nodes, in order to eliminate safety hazards, while also configure the firewall on the backbone nodes. This can greatly improve the security of the site, and reduce the risk of loss due to malicious network attacks.
2, the backbone nodes configure the firewall
firewall itself can be a variety of defense DDoS attacks and some other attacks. The discovery of attack, you can attack directed to withstand some of the host, so you can protect what really matters hosts will not be attacked. Few of these hosts to withstand an attack, you can select the host unimportant, or Linux or Unix vulnerabilities such as their own ability to prevent and outstanding hosts.
3, with enough machines to withstand hacker attacks and devices
with enough machines and equipment to withstand hacker attacks This is an ideal coping strategies. If the user has sufficient capacity and sufficient resources to withstand hacker attacks. So when the hacker attacks continue to access the target host, target host and take up system resources, their attacks will gradually resource consumption. Perhaps even before the target host is paralyzed attacks, hackers itself has been unable to a Weapon. However, this coping strategy, need to invest more money relative, usually most of the equipment also is idle, is not conducive to small and medium enterprises to save costs and expenses.
4, using load balancing equipment, reduce consumption and losses caused by cyber attacks
Using load balancing equipment defensive way is to take advantage of all the network equipment to protect the security and stability of the network environment. Generally include "routers, firewalls" and other equipment. When external attacks, the first attack of a router, other machines this time, has not been affected. And hang up the router after the restart will resume normal use, and there is no loss. But if other machines under attack lead to crashes, such as a server, it is likely to lose data, reboot the server at the same time would be a relatively long process. And if a "router" This load balancing equipment, when a router is attacked paralyzed, another can take over its work to continue, to the greatest extent possible to cut consumption and losses caused by network attacks.
5, closed off some unnecessary services port
as well as one of the most common practice is to close off some unnecessary services port, only open the necessary port services. For example, many Web server is only open port 80, while all other ports will be blocked off or make policy on the firewall, so that when under attack, the firewall will play the role of blocking.
6, the resilient guard bandwidth upgrades
in the original security at the end of the bandwidth, the bandwidth upgrade to provide elasticity to enhance the protection, the user can flexibly select bandwidth. Usually the more bandwidth, the more there is to deal with high-volume attack protection capabilities.
