Abstract

The utilization of technology at this time increasingly encourages businesses or industries to build an efficient work ecosystem. Inventory management is one of the important keys in the company's ecosystem. Inventory management is a process of managing and monitoring raw or finished goods. CV Lafeby is a medium-sized business engaged in textiles. Currently CV Lafeby still uses a conventional system in managing its inventory management such as recording incoming products using paper or making paper notes. The use of conventional systems has many problems such as the absence of up to date product data and the use of paper notes is too risky to be damaged or lost. The impact of incomplete data on incoming goods and outgoing goods will affect CV Lafeby in the future. Therefore, CV Lafeby needs an inventory management system by utilizing technology, namely a mobile application and mysql database. The author uses the agile development method in developing mobile applications. Later, the backend of the mobile application will be built through hosting so that the data can be obtained up to date. Hopefully, the mobile application that the author will develop can solve the problems of the shortcomings caused by conventional systems in inventory management.

Abstract

With the growth of increasingly innovative technology, new media have been created to convey information, namely web applications. Current technology is needed to disseminate information widely and without borders. A web server being paralyzed can disrupt the client's process of accessing information. Web server paralysis can be caused by several attacks, one of which is Distributed Denial of Service (DDoS). The author uses Kali Linux as penetration testing software, using the GoldenEye tool as this tool can be used to test whether a site is vulnerable to DDoS attacks. Security design with Cloudflare involves implementing multiple layers of protection designed to mitigate security risks to applications and websites. In general, Cloudflare Web Application Firewall (WAF) is placed in front of the origin server to detect and block web-based attacks. Cloudflare's DDoS protection service is applied at a global layer, securing infrastructure from hacker attacks. Leveraging Cloudflare's infrastructure, this design provides an effective and efficient security solution against DDoS attacks, ensuring the availability and reliability of network services

Abstract

In the digital era, computer networks serve as a crucial foundation for various aspects of life, including business and education. Network security, encompassing data confidentiality, integrity, and availability, is a critical factor in protecting against cyber threats. Universitas Internasional Batam (UIB) faces challenges such as intrusion and hacking, necessitating additional security measures. To address these challenges, the implementation of Zero Trust Network Access (ZTNA) supported by Virtual Private Network (VPN) and Multi-Factor Authentication (MFA) has become a highly relevant strategy. ZTNA ensures that every request for network access is evaluated individually, without assuming trust in any entity, thereby enhancing the necessary security layers. This study employs the Network Development Life Cycle (NDLC) method to design and develop a ZTNA network at UIB using the ZeroTier platform. The process includes network and security requirements analysis, ZTNA architecture design, implementation across various devices, and MFA integration with Google Authenticator. Monitoring and Quality of Service (QoS) testing using iPerf were also conducted to ensure the system's effectiveness. The research findings demonstrate that ZeroTier effectively facilitates direct communication with high-quality service, while the enhanced security provided by MFA makes it a reliable and secure solution for the exchange of sensitive data in the dynamic and complex environment of the university.
