Wireless network security is concerned. Several countermeasures to ensure security

Technology is getting more and more benefits for us, so the progress of the network is a must. The wireless network is really convenient for the public, but more and more wireless products are being put into use, and the concept of wireless security is not the wind. The rain is small, whether it is a coffee shop, an airport wireless network, or a wireless router from home has become a target for hackers. So how can we guarantee our own wireless security? First, we must control the eligibility to enter the network, that is, authentication; secondly, protect the information sent wirelessly, that is, data encryption.

Then we talked about how to ensure wireless security through the ten countermeasures provided by Com company to prevent hacker attacks.

1. Place the access point device for the network correctly

Start with the basics: In the network configuration, make sure that the wireless access point is outside the firewall.

2. Use MAC to block hackers

Use MAC address-based ACLs (access control lists) to ensure that only registered devices can enter the network. MAC filtering technology is like adding a lock to the front door of the system. The more obstacles are set, the more hackers will be able to retreat and they have to turn to other low-security networks.

3. Effectively manage the ID of the wireless network

All WLANs have a default SSID (service identifier) ​​or network name. Change the name immediately, represented by text and number signs. If your organization has network management capabilities, you should change the SSID periodically. Don't use this name everywhere: cancel the SSID autoplay feature.

4. Importance of WEP Protocol

WEP is the standard network security protocol for 802.11b WLAN. When transmitting information, WEP can provide protection similar to wired transmission by encrypting wireless transmission of data. The default value of the WEP key should be changed immediately after a simple installation and startup. The most ideal way is that the WEP key can be dynamically changed after the user logs in, so that hackers need to keep track of this change when they want to get data from the wireless network. Session- and user-based WEP security management technology can achieve optimal protection, adding another layer of defense to the network to ensure wireless security.
