Hey there! Today, let's chat about how to keep our networks safe from intruders. Just like we lock our doors when we go out, our networks need some security measures to prevent unwelcome guests.

5G Network Security

5G networks are like super-fast highways for data to zip through. But if we're not careful, bad guys might hitch a ride on this expressway. Here are some ways to keep your 5G network secure:

SIM Card "ID Card"

When you connect to a 5G network with your SIM card, it's like entering a private club where you need to show your ID to prove who you are. This process is called "mutual authentication," ensuring that only you and the network know the secret to connect.

5G Gateway "Anti-Theft Locks"

The 5G gateway is like the front door of your home, and you can set up various locks to prevent burglars. For example, it can lock the SIM card, lock specific frequency bands, or lock the cell, so only your devices can use the network.

WiFi Network Security

For most of us, WiFi is like our backyard, which needs to be well protected. Here are some ways to make your WiFi more secure:

Hide WiFi Name

Hiding your WiFi name (SSID) is like hiding the house number of your backyard gate, so others can't find your network and can't intrude without permission.

MAC Address Filtering

The MAC address is like the "ID number" of a device. With MAC address filtering, you can decide which devices with the "right ID number" can enter your network.

PSK Pre-Shared Key

This is like a secret password between you and your WiFi. You have to enter this password on your device, and if the password is correct, you can connect to the network.

Data Encryption

Data encryption is like putting a lock on your package. WPA, WPA2, 802.11i are like different types of locks, while WEP, TKIP, CCMP are like the types of locks. Especially CCMP, it uses an advanced lock called AES, with a 128-bit random password, plus CBC-MAC as a check code, to ensure your data is delivered safely.

In summary, by following these simple steps, we can ensure our networks are both fast and secure. Just as we wouldn't give our house keys to just anyone, we also need to make sure our networks are used only by authorized individuals. I hope everyone can have a network environment that is both speedy and secure!
