High-Intensity Cybersecurity & Offensive Depths
Wi-Fi 7 and Wireless Vulnerabilities
Wi-Fi 7 adds multi-link operation, wider channels, and higher throughput, which expands the attack surface around pairing, roaming, and management frames. Wireless vulnerabilities still center on weak authentication, rogue access points, evil twins, and downgrade attacks against older protocols. Defending modern wireless means enforcing WPA3, segmenting guest and IoT traffic, and monitoring the radio environment rather than trusting the SSID.
핵심 내용
- Require WPA3 with SAE and disable legacy WPA2 and open networks where possible.
- Segment guest, IoT, and corporate traffic into separate VLANs with firewall rules between them.
- Monitor for rogue and evil-twin access points using wireless intrusion detection.
- Disable WPS and other convenience pairing features that bypass strong authentication.
- Use certificate-based authentication for corporate devices instead of shared passphrases.
- Keep firmware updated on access points and clients to close protocol-level flaws.
- Limit management-plane access to controllers and log all configuration changes.
- Test wireless security with authorized assessments that include evil-twin and downgrade scenarios.
자주 묻는 질문
Is WPA3 enough on its own?
No, it strengthens authentication but does not stop rogue APs or physical-layer attacks.
What is an evil twin attack?
An attacker broadcasts a lookalike network to capture credentials or traffic from connecting clients.
Should IoT devices share the corporate Wi-Fi?
No, isolate them on a restricted segment with only the access they need.
How do we detect wireless attacks?
Wireless intrusion detection that monitors channels for rogue APs and anomalous frames.
