Final answer:
To improve security in a wireless network, one should use strong encryption (like WPA3), change the default SSID and password, employ MAC address filtering, update router firmware, disable remote administration, and monitor network activity.
Step-by-step explanation:
To increase security in a wireless network, the best action is to implement several security measures that work together to protect the network. Here are a few important steps you can take:
- Use a strong encryption method like WPA3 or, if not available, WPA2. Avoid outdated protocols like WEP.
- Change the default network name (SSID) and disable SSID broadcasting to make it less visible to potential intruders.
- Create a strong, complex password and change it regularly.
- Limit access to the network by using MAC address filtering, though be aware this is not foolproof.
- Update router firmware regularly to ensure you have the latest security patches.
- Disable remote administrative access to the router.
- Regularly monitor network activity for any unusual behavior.
Combining these actions will greatly enhance the security of a wireless network, helping protect against unauthorized access and threats.
