Final answer:
To prevent unwanted intrusions on a wireless network, secure your WiFi with a strong password, use WPA2 or WPA3 encryption, enable network firewalls, install anti-virus software, and be cautious with privacy settings and friend requests to enhance Internet privacy and security.
Step-by-step explanation:
To prevent unwanted intrusions when using a wireless network, it's crucial to take several steps to safeguard your connection and devices. Firstly, securing your WiFi with a strong, unique password and changing it regularly can help protect against unauthorized access. Implementing encryption, such as WPA2 or WPA3, on your wireless router can also prevent eavesdroppers from capturing your data.
Enabling network firewalls and using anti-virus software can defend against malware and hacking attempts. It's equally important to be cautious with the physical security of devices. Keeping mobile phones away from the body and using hands-free can decrease exposure to radiation and prevent inadvertent connections to unsecured networks.
Also, be vigilant about your privacy settings and cautious when accepting friend requests, as personal information can be exploited for network intrusion. By being proactive about Internet privacy and security, you establish barriers against intrusions and safeguard your online presence.
