inSSIDer Office will give a Security Warning if your network is using WEP.
WEP is known to be flawed as a wireless security type. WEP is easily cracked with free tools, allowing a potential malicious hacker to access your network resources and monitor your wireless traffic.
- Switch to WPA2 with a strong password for maximum wireless security.
- Use WPA only if you need to support legacy wireless devices. While not as secure as WPA2, WPA is far more secure than WEP.
- Disable WPS, which as a part of WPA/WPA2, is easy to brute-force attack.
