Wi-fi between hotel rooms can be linked to each other, will there be network security risks?

Public WiFi in hotel rooms will have network security risks. Many merchants will provide WiFi access service to attract customers. When guests find a WiFi hotspot, they usually ask the waiter for the connection password. Hackers will provide a free WiFi access point similar to the name of the merchant to attract netizens to access it.

Once connected to the WiFi hotspot set by the hacker, all data packets on the Internet will be forwarded by the hacker's device, which can be intercepted and analyzed, and some unencrypted communications can be viewed directly.

In addition to disguising the same WiFi trap as the normal WiFi access point, the attacker can also create an access point with the same name as the normal WiFi access point. Because the signal coverage of the wireless router is not stable enough, your mobile phone will automatically connect to the WiFi hotspot created by the attacker. Once again, you unconsciously fell into the trap.

Extended data:

There are different types of network security due to different environments and applications. There are mainly the following types:

system safety

Running system security is to ensure the security of information processing and transmission system. Its key point is to ensure the normal operation of the system. Avoid the destruction and loss of messages stored, processed and transmitted by the system due to the crash and damage of the system. Avoid information leakage, interference or interference from others caused by electromagnetic leakage.

Network security

Security of network system information. Including user password authentication, user access control, data access control, mode control and security audit. Security issues followed. Computer virus prevention, data encryption, etc.

Information dissemination security

The security of information dissemination on the network refers to the security of the consequences of information dissemination, including information filtering. The key point is to prevent and control the consequences caused by the spread of illegal and harmful information, and to avoid the information circulating freely on the public network from getting out of control.

Information content security

Security of network information content. It focuses on protecting the confidentiality, authenticity and integrity of information. Avoid attackers using the security vulnerabilities of the system to eavesdrop, impersonate, cheat and other behaviors harmful to legitimate users. Its essence is to protect the interests and privacy of users.
