The difference between DOS attack and DDOS attack
Both DDOS and DOS attacks will make the computer or network unable to provide normal services; while DDOS and DOS The difference is that DDOS is a kind of distributed denial of service, which will unite multiple computers as an attack platform to launch DDoS attacks on one or more targets, thereby exponentially increasing the power of the denial of service attack.
How to prevent DOS attacks and DDOS attacks
1. Bandwidth resources must be sufficient
Bandwidth directly determines the ability to resist DDOS attacks. Choose at least 100M bandwidth, the more the better.
2. Server hardware configuration
On the premise that bandwidth and traffic are fully guaranteed, the server hardware configuration must keep up. Of course, the main factors are CPU and memory
3. Standardize your own operation settings
For the prevention of DOS and DDOS attacks, the main defense capability still depends on the server and The computer room itself. However, for us users, we also need to operate safely. For example, do not upload files with unfamiliar or special suffix names to the server, do not click on links from unknown sources, and do not install software from unknown sources to prevent the server from being attacked due to your own operational problems. At the same time, it is best to conduct security scans of the website's files regularly, so that new vulnerabilities and virus files can be discovered and cleaned up in a timely manner.
4. Configuration of computer room firewall
Generally speaking, configuring a firewall on a backbone node can effectively resist DOS and DDOS attacks. Because when the firewall is discovered to be under attack, it can direct the attack to some "useless" servers, which can protect running servers from being attacked.
