Smartphone has been a popular device utilized to support productivity in human life and has become an integral part of human activities such as for communication, entertainment and social interaction. Those activities can be related to the information which needs to be protected because of its high privacy. Therefore, the smartphone needs a procedure that demonstrates an ability to secure that user information. However, more protective the scheme, more difficult the usage. Based on that pattern behavior, a good security scheme which support the users for easy security feature is urgently needed. One of such kind security features is authentication feature. In that manner, the ease of use aspect for acquiring the system by using an easy authentication mechanism becomes critically important. The ease of use intended is the efficiency of interaction between the user and that security feature for doing authentication including the time needed for doing that. This study developed the app which utilizes the context data, namely Geofilock. The context data meant is the location data based on the GPS and MAC address of the Wi-Fi. The system detected both context data and determined whether the smartphone needs to show the pattern screen lock as authentication feature or not, based on the context data analysis. The functionality of Geofilock works properly as shown by less user interaction number and less time needed by the user for obtaining the access. In addition, the app is easy to operate, as suggested by the user feedback.

The classification of data traffic in a firewall using parameters such as port number, IP address, and MAC address is not sufficient. For example, currently, many applications can be used without a port number meaning they can easily circumvent a firewall. Firewalls inspecting up to only layer four could allow malicious data to pass. Next-generation deep packet inspection (DPI) is a method that can be used for firewalls as a method of classification up to layer seven in data traffic control. This research recommends the use of nDPI and L7-filter by network administrators on existing open source firewalls. Eleven internet applications were used to test and analyze nDPI and L7-filter which are capable of detecting traffic based on the data signature. nDPI and L7-filter were tested for accuracy and speed of total time of execution in live performance networks. We conclude that the development of next-generation deep packet inspection is important for the future of system and network security.

Kegiatan Sosialisasi Internet sehat untuk komunitas Salimah merupakan kegiatan Pengabdian Masyarakat yang diadakan untuk meningkatkan pengetahuan dan pemahaman dalam menggunakan internet secara sehat dan aman. Hal ini dikarenakan peserta kegiatan berasal dari komunitas Salimah yang beranggotakan perempuan dan sebagian besar sudah berumah tangga dan memiliki anak, sehingga kegiatan yang dilaksanakan melalui sharing session diharapkan dapat memberikan informasi terkait ancaman dan bahaya pada saat menggunakan internet serta tips dan trik penggunaan internet yang aman bagi seluruh anggota seluruh anggota keluarganya. Kegiatan sosialisasi internet sehat dilaksanakan melalui dua sesi presentasi menggunakan aplikasi power point dan aplikasi youtube yaitu sesi pertama terkait dengan pengunaan internet sehat yang berisi informasi terkait dampak positif dan negative yang muncul saat menggunakan internet serta teknik yang aman menggunakan Internet. Sesi kedua merupakan sosialisasi penggunaan gadget yang bijak. Sedangkan proses tanya jawab dilaksanakan pada sesi 3, berdasarkan kuisioner yang telah disebarkan kepada 16 peserta, menunjukkan bahwa 100% peserta menyatakan kegiatan ini sangat bermanfaat dan sesuai dengan kebutuhan dari peserta pengabdian masyarakat,
