cause more serious consequences on a system than on other systems. It is necessary to test various situations in the image production environment, not just forecasts, and re-test after changing any part of the infrastructure. 3. Build Load Balancing for the infrastructure Once the critical point is identified, the next step should be to establish Load Balancing for the infrastructure, with the goal of optimizing communication flows under normal and peak loads. 4. Considering the scalability

In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con

is 65536 bytes. Although the length of a package cannot exceed 65536 bytes, the overlapping of multiple segments of a package can be achieved. When a host receives a packet larger than 65536 bytes, it is under the Ping of Death attack, which will cause host downtime. Teardrop: When an IP packet is transmitted over the network, the packet can be divided into smaller segments. Attackers can perform TearDrop attacks by sending two (or more) packets. The offset of the first package is 0, the length

DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing firewall equipment will be paralyzed due to limited processing capacity, become a network

How does PHPApache implement image high-level anti-image acquisition websites? The content page has only one image. You do not need to consider search engine optimization. Is there any way to prevent high-level data collection? The first time I wrote a program, I do not know much about it. I hope your predecessors will advise me. PHP Apache: How to Implement image anti-
