In the era of information technology advancement, web applications have become a means of seeking information. However, with technological progress, they have become increasingly vulnerable to cyber attacks such as SQL Injection and Cross-Site Scripting (XSS). This research aims to implement the Teler-waf Web Application Firewall (WAF) to protect web applications from such attacks. The research methodology includes the implementation of the Teler-waf WAF, analysis of web application security, and testing the speed of attack detection. The results show that Teler-waf is effective in preventing attacks, and its integration with Telegram bots provides real-time notifications to system administrators, enhancing security responsiveness. This research contributes to strengthening web application security and understanding the role of the Teler-waf WAF in addressing cyber threats.

Salah satu bentuk dari pemanfaatan kemajuan teknologi berupa penerapan aplikasi web menggunakan web server untuk berbagi informasi, memberikan layanan, dan menyimpan data. Dibalik kemudahan dalam penggunaan aplikasi web yang dapat diakses darimana pun, terdapat risiko ancaman keamanan siber yang cukup besar dimana aplikasi web dapat menjadi target serangan oleh penjahat siber yang ingin mencuri informasi sensitif atau mengambil alih sistem. Masalah keamanan tersebut dapat diatasi dengan pendekatan reaktif yaitu penerapan sistem keamanan yang mampu mendeteksi dan menganalisa insiden keamanan pada aplikasi web secara cepat dan efektif. Salah satu solusi yang dapat digunakan adalah dengan mengimplementasikan Security Information and Event Management (SIEM). SIEM adalah sistem yang dapat digunakan untuk mengelola log yang dihasilkan dari berbagai sumber data seperti endpoint, perangkat jaringan, maupun firewall, Salah satu aplikasi SIEM yang bersifat open source dan dapat digunakan untuk deteksi serta analisa insiden serangan siber adalah Wazuh. Wazuh adalah perangkat lunak open source yang berfungsi sebagai sistem deteksi berbasis host (endpoint) yang menyatukan kemampuan XDR (External Data Representation). Metode yang digunakan dalam penyelesaian masalah tersebut menggunakan metode Eksperimental, ada 5 tahapan dalam metode eksperimental ini yaitu analisis kebutuhan, desain, implementasi, pengujian, evaluasi. Hasil dari pengujian tersebut dapat di deteksi oleh Wazuh sebagai SIEM untuk memonitoring keamanan server dan deteksi penyerangan.

The Windows operating system has become one of the main targets for cyber attackers because of its popularity among computer users. Therefore, developing an effective integrated security system is essential to protect the Windows operating system from various cyber threats. This journal discusses integrated security system development strategies that include the use of encryption technology, firewalls, malware scanning, system updates, and user awareness. Apart from that, this journal also discusses the implementation of an integrated security strategy to protect the Windows operating system from increasingly complex cyber attacks. The goal of this journal is to provide strategic guidance for IT security professionals and researchers in developing an effective integrated security system to protect the Windows operating system from ever-evolving cyber threats.

Building a computer network needs significant care in selecting a configuration to ensure its efficacy and efficiency. It involves decisions about network topology, types, and device use. Security measures are essential for protecting networks with internet access from external attacks. A study conducted at an Islamic university in Indonesia indicated the use of a star network architecture and a client-server network model. The servers utilize Debian Linux. The university's security infrastructure includes a server authentication system and the setting up of a Virtual Private Network (VPN). If the server authentication difficulty is caused by a power outage, it is recommended that you use an UPS (uninterruptible power supply) to preserve power stability. Overall, security methods show up to be more effective when firewalls are installed.
