WHY IT NEEDS A POLICY

Why aireplay_fakeauth needs a policy

This tool actively transmits crafted 802.11 frames to authenticate with an access point under false pretenses, which is an active network attack operation. It executes an external wireless network operation that affects a remote system (the AP). While it does not delete data, it performs unauthorized network interaction (fake auth injection) that is a prerequisite step in WEP cracking attacks.
