What are the factors that threaten network security?
There are many factors that affect computer network security and threaten network security It mainly comes from three factors: human unintentional errors, human malicious attacks, network software system vulnerabilities and "backdoors", which are summarized as follows:
Threats to the network itself
1 ． Application system and software security vulnerabilities. It is difficult to ensure the security of web servers and browsers. Initially, people introduced programs to make the homepage come alive. However, many people did not know much about the software packages when programming. Most people did not program new programs, but made appropriate modifications to the programs. , in this way, many programs will inevitably have the same security vulnerabilities. And every operating system or network software cannot be perfect, so it is always in a dangerous situation. Once connected to the network, it may become a target of attack.
２． security strategy. Security vulnerabilities result from improper security configuration. For example, if firewall software is configured incorrectly, it will not work at all. Many sites unintentionally expand access permissions through firewall configurations, ignoring the fact that these permissions can be abused by others. The main purpose of network intrusion is to obtain storage permissions, write permissions and access to other storage contents of the system, or to use it as a springboard to further enter other systems, or to maliciously damage the system, causing it to be damaged and lose service capabilities. For a specific network application, when it is launched, it opens a series of security gaps, and many applications bundled with the software are also enabled. Unless the user disables the program or configures it correctly, security risks remain.
3. Backdoors and Trojans. In computer systems, backdoors refer to access passwords deliberately set in programs by software and hardware producers for unauthorized access. However, due to the large presence of backdoors, they pose a potentially serious threat to computer systems in the network. Trojan horse is a special type of backdoor program. It is a hacking tool based on remote control and has the characteristics of concealment and unauthorizedness. If a computer is installed with a Trojan horse server program, hackers can use the Trojan horse controller program to enter This computer achieves the purpose of controlling the computer through the command server program.
