Common Wi-Fi Security Myths Debunked
When it comes to Wi-Fi security, there are several myths that can lull you into a false sense of security. Let’s debunk some of these common myths:
Myth: Wi-Fi Networks are Secure by Default
This is a common misconception. Most Wi-Fi routers come with a default administrator password and network name (SSID) that are publicly available. This means that anyone can access your router’s settings and configuration. To secure your network, you must change these default settings and configure your router correctly.
Myth: WEP is a Secure Encryption Protocol
WEP (Wired Equivalent Privacy) is an outdated encryption protocol that can be easily cracked by hackers. WEP is not a secure encryption protocol and should be avoided at all costs. Instead, opt for WPA2 (Wi-Fi Protected Access 2) or WPA3, which are much more secure.
Myth: MAC Address Filtering is Foolproof
MAC (Media Access Control) address filtering is a security feature that allows you to restrict access to your network based on device MAC addresses. While this can provide some level of security, it’s not foolproof. MAC addresses can be easily spoofed, allowing hackers to bypass this security measure.
