Wireless Security on the Philippine Setting

This document explores the state of wireless security in the Philippines, highlighting a 2004 discovery of unencrypted Wi-Fi networks in Manila. As homes and small businesses proliferate their use of Wi-Fi, many remain unaware of security risks. We discuss vulnerabilities of old protocols like WEP and improvements with WPA and WPA2. Key tools for assessing wireless security, such as Kismet and Aircrack, are introduced. Effective security measures are recommended, including changing default settings, implementing MAC address filtering, and limiting connections to safeguard against unauthorized access.
