What it means
Wireless networks extend beyond physical walls and can expose management frames, guest access, personal devices, and unauthorized access points. Enterprise and home deployments require different levels of identity, segmentation, and monitoring.
Why it matters
A secure wired environment can still be bypassed if wireless access is weak or unmanaged.
Practical focus
- Use current encryption and authentication methods
- Separate guest, personal, and managed-device access
- Protect access point administration
- Monitor for rogue and misconfigured wireless devices
Common mistakes
- Using shared passwords indefinitely
- Treating hidden network names as a security control
- Extending coverage without considering physical boundaries
