With the widespread application and rapid development of Internet technology, DDoS traffic attack cases are frequent, and website protection from DDoS has become more and more important. Only by taking effective website security protection measures can you better defend against hacker attacks.
Recently, the WeChat official account of the Ministry of Public Security issued an important reminder: The shared power bank you often use may be implanted with a Trojan horse program. Once you plug it into your phone, it may steal your personal privacy information, including address book, photos, Video and so on. A small power bank may become a means for others to attack you. With the continuous renovation of hacking technology, the complexity and scale of DDoS attacks continue to increase, and it has gradually become one of the main criminal methods of blackmail and unfair competition. , Causing huge economic losses to the victims, so we must put the establishment of website protection DDoS measures in the first place of network security.
Common large-flow attacks are: DDoS attacks and CC attacks
DDoS attacks and distributed denial of service attacks refer to the control of multiple agents to launch attacks on the target through the main control end, thereby exponentially increasing the power of DoS. The attacked website may not open the website page, a large number of game players are dropped, the server is stuck, the network is blocked, etc.
CC attack means that the attacked host is constantly receiving a large number of data packets sent by the attacker using the proxy server, which causes the server resources to be exhausted, until it crashes. It can be seen from the principle of CC attack that its attack technology content is not high, so it is not that difficult to defend against CC.
Internet servers are now in dire straits, and websites are the most vulnerable application type to this type of attack. At this time, high-defense IP is particularly important. High-defense IP has the function of hiding the origin site. Generally, websites encounter frequent attacks. Choose high Anti-IP protection against DDoS/CC attacks is perfect.
Therefore, it is very necessary to use high-defense IP series products to protect against DDoS attacks. High-defense IP is a paid value-added service launched for Internet servers that are unavailable after a large-traffic DDoS attack. Users can configure high-defense IP to divert attack traffic to high-defense IP to ensure the source site’s Stable and reliable.
High-defense IP targets attacks based on traditional proxy, detection, rebound, authentication, black and white lists, message compliance and other standard technologies, combined with Web security filtering, reputation, seven-layer application analysis, user behavior analysis, feature learning, and protection Confrontation and other technologies are used to block and filter threats to ensure that protected users can still provide business services to the outside world while the attack continues.
The essence of protecting against DDoS attacks is actually to alleviate the resource occupation, server jams or even crashes caused by the website being attacked and unable to provide services to normal users. You can choose to improve the hardware performance, thereby enhancing the website's capacity to carry traffic. However, when faced with a large-scale traffic attack, this approach basically does not do much, and the cost is high. More companies will choose to purchase high-defense services to defend against attacks, such as high-defense IP, high-defense CDN, etc. High-defense CDN can not only speed up website response, but also effectively clean up DDoS attacks.
