<![CDATA[Rapid progress in Artificial Intelligence (AI) has driven the emergence of applications thatsupport digital literacy, one being GlassWire, which offers both mobile data usagemonitoring and firewall functions on Android devices. Vocational high school (SMK)students typically know AI only in its chatbot form and have had little hands-on exposureto traffic monitoring or firewall-based access control. Through GlassWire training, this community service program sought to build up the network literacy of Computer andNetwork Engineering (TKJ) and Building Design Engineering (TGB) students at SMKMuhammadiyah 3 Yogyakarta. Eighty-five grade X and XI students took part in the singledaysession, which opened with an initial assessment of prior knowledge, moved througha material presentation and hands-on installation and configuration of GlassWire on eachstudent's own device with accompanying discussion, and closed with a final assessment ofpractical outcomes. The instructor's initial assessment found that none of the students werefamiliar with GlassWire in particular, though roughly a quarter already grasped the generalidea of mobile data monitoring and firewalls. By the closing assessment, every student(100%) had completed the GlassWire installation with all features intact, and among arandomly sampled group questioned afterward, about 90% could explain or show how touse and configure the relevant features. The program's outputs include an online mediaarticle and a national journal publication, intended as a simple model for strengtheningnetwork literacy among vocational students.]]>
