Nine Measures to Protect enterprises' Wireless Network Security

The development of wireless network technology can be described as rapid. How should we set the network for many of our network technicians in the Enterprise? Next we will summarize nine methods to address enterprise network security.

Generally, the devices used by hackers cannot reach the wireless network, and they cannot break into the network. Some routers allow you to control the signal strength of broadcast. If you have this option, you can reduce the router signal to the weakest strength required. In addition, you can disable the wireless router at night or in other periods that are not used.

You do not have to be a system expert to effectively protect yourself from hackers. It is difficult to prevent hackers from accessing invisible and invisible things like electronic signals. This is why protecting wireless network security is always challenging. If your wireless network is insecure, your company and data will face great risks. In this way, hackers may be able to monitor the websites you visit or view what information you have exchanged with your business partners. Maybe they can log on to your network and access your files.

Although wireless networks have been vulnerable to hacker intrusion, their security has been greatly enhanced. The following methods help you increase the security factor.

Enterprise Network Security Settings 1. Install a secure wireless router

This device connects your computer on the Internet. Note: not all routers are born the same. At least, the router must have the following three functions: (1) support the least vulnerable password; (2) You can hide yourself, prevent Unauthorized and overly curious people from accessing the network; and (3) prevent anyone from accessing the network through an unauthorized computer.

Enterprise Network Security Settings 2. Select a secure vro name

You can use the Configuration Software of the manufacturer to complete this step. The name of a vro is used as a broadcast point (also called a hotspot). Anyone who tries to connect to a wireless network within the vro broadcast area can see it. Do not use the router brand name or model as its name. In this case, hackers can easily find out possible security vulnerabilities on the vro.

Similarly, if you use your own name, address, company name, or project team as the name of the vro, it is tantamount to helping hackers guess your network password.

You can use this method to ensure the security of the vro name: The name consists of a random letter and number, or any other string that does not disclose the vro model or your identity.

Enterprise Network Security Settings 3. Custom passwords

The default password of the router factory settings should be changed. If you let the hacker know the vro model, they will know the default vro password. If the configuration software allows remote management, disable this function so that no one can control router settings over the Internet.

Enterprise Network Security Settings 4. Hide the vro name

After you select a security name, you need to hide the vro name to avoid broadcasting. This name is also called the Service Set Identifier (SSID ).

Once you complete this step, the vro will not appear on the vro broadcast list in your region, and the neighbors and hackers will not be able to see your wireless network. In the future, you can broadcast signals, and hackers need complicated devices to determine whether you have wireless networks.

Enterprise Network Security Settings 5. restrict network access

Use a method called MAC address filtering to prevent unauthorized computers from connecting to your wireless network. To do this, you must first find out the Media Access Control (MAC) addresses that are allowed to connect to each computer on your network. All computers are identified by 12-character long MAC addresses. To view your computers, click Start, click Run, Enter cmd, and click OK ". A new window with a DOS prompt will be opened.

Enter ipconfig/all and press enter to view information about all computer NICs. The Physical Address column displays the MAC Address of the computer.

Once you have a list of authorized MAC addresses, you can use the installation software to access the MAC address control table of the vro. Then, enter the MAC address of each computer that is allowed to connect to the network. If the MAC address of a computer does not appear on this list, it cannot connect to your vro or network.

Note: This is not a foolproof security method. Experienced hackers can set a fake mac address for their computers. But they need to know which MAC addresses are on your authorized computer list. Unfortunately, because the MAC address is not encrypted during transmission, hackers only need to detect or monitor the packets transmitted over your network to know which MAC addresses are on the list. Therefore, MAC address filtering is only intended for new hackers. However, if you get rid of hacker thoughts, they may miss your network and attack networks that do not filter MAC addresses.
