Precautionary Measures for the Use of Public Wi Fi

Abstract

Public Wi‑Fi networks in cafés, airports, and libraries lack robust security controls, exposing users to eavesdropping and data theft (National Institute of Standards and Technology, 2020). Despite 66.5% expressing concern, 23.5% forgo protective measures, yet 43% check email and 20% make purchases on public Wi‑Fi (Panda Security, 2025; Zimperium, 2025).
