Abstract
The reliability of data packet transmission within the deployed Wireless Local Area Network (WLAN) security protocol is highly crucial to ensure user data confidentiality. This study aims to analyze the security implementation of the WPA2-Personal protocol-based WLAN through direct observation of data packet traffic. A qualitative-descriptive research method was applied by conducting packet capturing using the Wireshark application on a small-scale test network utilizing a smartphone as an access point and a laptop as a client. The results demonstrate that all local and internet data communication activities operated stably and were recorded consistently. Packet analysis successfully identified various major protocols, including ARP, DNS, TCP, UDP, TLS, and HTTPS. The implementation of TLS encryption on HTTPS traffic proved capable of protecting the confidentiality of application data content, preventing it from being read in plaintext even though the packets were successfully captured. This study concludes that the combination of WPA2-Personal authentication and the HTTPS communication protocol still provides adequate security protection and remains highly viable for small-scale wireless network environments.
