<![CDATA[Untuk semakin menghemat biaya dalam penggunaan layanan cloud di Azure, maka dapat menggunakan arsitektur multi-tenant. Arsitektur multi-tenant memungkinkan pengguna untuk menggunakan layanan cloud secara bersama-sama. Namun ada hal yang perlu diperhatikan saat menggunakan layanan multi-tenant, salah satunya adalah keamanan database antar pengguna. Salah satu solusi untuk mengatasi hal tersebut adalah dengan melakukan pendekatan separate database. Penelitian ini bertujuan untuk meningkatkan keamanan data pada metode multi tenant dengan pendekatan separate database pada layanan Microsoft Azure. Metode yang dilakukan pada penelitian ini adalah metode multi tenant dengan pendekatan arsitektur database yang digunakan adalah separate database, dan jenis layanan cloud yang digunakan adalah Paas (Platform as a Service) yang mana menggunakan Azure App Service dan Azure SQL Database dalam melakukan proses migrasi. Hasil dari penelitian ini adalah melakukan migrasi database dengan pendekatan separate database dari masing-masing pengguna layanan ke dalam layanan Azure. Hal ini dapat meningkatkan keamanan data antar pengguna sehingga tidak terjadi kebocoran data karena masing-masing pengguna memiliki databasenya sendiri.Desain arsitektur multi tenant separated database memiliki manfaat yaitu keamanan data yang lebih baik, karena tiap tenant memiliki database tersendiri sehingga data dari tiap tenant tidak bercampur menjadi satu. Sementara dari segi biaya layanan Azure App lebih hemat dibandingkan dengan layanan Azure Virtual Machine]]>

<![CDATA[Education in Indonesia is growing rapidly, schools provide the internet for learning activities by accessing educational content that has been created by schools through online learning media. SMP Stella Matutina Salatiga as a case study place, in learning activities using online learning media is not optimal because many school residents use the internet to access social media. To overcome this problem, it is necessary to manage internet bandwidth by implementing the Hierarchical Token Bucket (HTB) method. This bandwidth distribution aims to facilitate learning activities, where bandwidth will be prioritized for online learning media. By dividing the bandwidth using the HTB method, the bandwidth is more organized. The results of the test were carried out by measuring the QoS parameters using video streaming services and interactive services which experienced an increase in network quality after the HTB method was applied, it was marked by a decrease in the average value of jitter, delay, and packet loss, which means the throughput obtained is greater. The application of the HTB method is of course learning to use online learning media to be more optimal.]]>

<![CDATA[Intrusion Detection System (IDS) is a system in charge of monitoring network traffic to detect suspicious and abnormal activity and provide alerts when such activity is detected. The use of the Intrusion Detection System is very helpful for administrators to monitor network traffic so as to minimize the occurrence of attacks that result in system damage and data theft. To minimize the occurrence of system damage and data theft by attackers, the author implements an Intrusion Detection System using Security Onion so that when an attack occurs it can be directly handled by the administrator. In this study, a test was conducted on Security Onion using the Signature Based method in detecting Remote Access Trojan attacks which according to BSSN data from January to April 2020 were the most common types of attacks. The results of this study can be used to detect cyber attacks that result in system damage and data theft.]]>

<![CDATA[Every computer needs and must have an IP Address to connect with other computer network users, the IP Address will be automatically distributed to network users using the Router as a DHCP Server. In addition to DHCP, the Router has a DHCP Accounting service that can improve network security with AAA and RADIUS Server features that can be implemented with Freeradius. DHCP Accounting has accounting capabilities for secure START and STOP message transmission, but the flash memory capacity on the C2691 router is around 32 MB, making the DHCP Accounting service not run optimally if it has many users. Using MySQL as a database can be a solution to this problem. When using the DHCP Accounting feature, data from DHCP Accounting will be sent and centralized on Freeradius. Accounting data centralized on Freeradius will be stored using a MySQL database so that the available storage space will be much larger and can accommodate more data from DHCP Accounting, as well as monitoring the network so as to improve network security for users.]]>

<![CDATA[The quality of user experience (Quality of Experience/QoE) in YouTube video streaming services is highly influenced by the quality of network service (Quality of Service/QoS). QoS measurement is conducted using Wireshark software with parameters such as throughput, packet loss, delay, and jitter, and assessed based on the TIPHON standard. Meanwhile, QoE is evaluated through a survey of 30 respondents and measured using the Likert scale.The analysis results indicate that QoS falls into the "Good" category, with a throughput of 1,545.45 kbps at 51.5%, 0% packet loss, 5.69 ms delay, and 0.0015 ms jitter. Additionally, the average QoE score of 4.55 suggests that the user experience is also considered good. Further analysis reveals a correlation between QoS and QoE, where a more optimal network quality positively impacts user experience. These findings provide insights for service providers to optimize streaming quality to meet user expectations.]]>
