<![CDATA[Computer networks typically use two primary transmission methods: wired and wireless networks, commonly referred to as Wireless Local Area Networks (WLANs). In WLAN implementations, the standard security mechanism frequently adopted is Wi-Fi Protected Access 2 Pre-Shared Key (WPA2-PSK), which relies on an SSID and password. Despite this security mechanism, criminal activities such as unauthorized access and network intrusions continue to occur. Therefore, it is essential to enhance network security to ensure that WLAN environments remain secure and capable of minimizing potential risks to users. This study aims to improve and optimize WLAN network security by conducting vulnerability scanning using Nessus to assess existing security conditions, followed by the implementation of hardening techniques to strengthen and obscure vulnerabilities. Hardening includes several approaches such as applying raw firewalls and firewall filters, restricting ports and services, disabling unnecessary services, disabling the MikroTik Neighbor Discovery Protocol (MNDP), and implementing port knocking as an additional layer of protection. The findings indicate that applying vulnerability scanning alongside a structured hardening strategy significantly minimizes identified risks and enhances the overall resilience of the WLAN network against intrusions and security threats.]]>

<![CDATA[The utilization of internet-based computer networks has become a fundamental necessity for supporting human activities in the modern era. This is particularly evident in various institutional activities, especially in academic settings such as colleges and schools, which heavily rely on internet network services. However, employing a large network segment with numerous hosts leads to excessive broadcast packet traffic. This issue is further compounded when the network is a flat network that lacks functional grouping for services and devices. To address these challenges, a network migration is necessary: shifting the existing Flat Local Area Network (LAN) to a hierarchical model based on the Cisco Enterprise Model, specifically employing the Enterprise Campus Area approach. This hierarchical design divides the LAN into several network layers, establishing more efficient Broadcast Domains and dedicated service functions, resulting in a system that is more modular and well-managed. The network was designed using the Top-Down method. The resulting design blueprint for the computer network system at STIK Bina Husada Palembang is intended to serve as a reference for future network planning and development.]]>

<![CDATA[A healthy environment significantly benefits the well-being of living organisms, particularly humans. As intelligent and social beings, humans are obligated to conserve, maintain, and safeguard environmental cleanliness to ensure a healthy and clean habitat. For instance, the Palembang City Sanitation Office designates specific public waste disposal points where citizens should deposit their waste into provided receptacles, thereby preventing indiscriminate dumping that can lead to environmental damage or pollution. However, the existing waste collection process presents a challenge: sanitation officers often do not know when a garbage collection point is full. This lack of information results in foul odors, unsightly conditions, and residents discarding waste onto the roadside. This research, therefore, aims to develop an Internet of Things (IoT)-based system capable of automatically providing notifications and information about the garbage bin's fill level via an Android smartphone. The device is engineered to utilize an Ultrasonic sensor to provide input data to the ESP8266, which then relays the trash bin's capacity status (empty, half-full, or full). Testing of this environmental pollution monitoring tool, specifically for monitoring trash bin capacity, demonstrated the system's ability to automatically and periodically provide status notifications. This function was confirmed during the testing period from 07:00 to 16:00.]]>

<![CDATA[The rapid progress of contemporary technology significantly aids in the execution of work. The internet, as one of the most developed technologies, facilitates communication, access to stored data, and generally simplifies professional tasks. However, this convenience is accompanied by criminal threats targeting internet users, with phishing (or SQL Injection, according to the Indonesian text) being a particularly damaging offense. Phishing is defined as a threat employing social engineering techniques to deceive users by impersonating an authorized entity. This type of attack is prevalent across various industrial sectors, including corporate, banking, and education. Key factors contributing to phishing in online banking services involve users' limited knowledge, psychological vulnerabilities, and social networking privacy issues. Therefore, securing computer networks is essential for the prevention of phishing (or SQL Injection) attacks. This study employs a qualitative research methodology with descriptive techniques.]]>
