Dengan berkembangnya teknologi komunikasi dan informasi melalui komunikasi data tanpa kabel yang dimana keamanan jaringan wireless LAN menjadi penting dan menjadi perhatian, jaringan yang terhubung ke internet pada dasarnya tidak aman dan selalu dapat diekploitasi oleh para hacker dan cracker. Ketika data berkomunikasi pada lalu lintas data dimana data dikirim dan melewati terminal untuk mencapai tujuan, maka pada saat itu pengguna lain yang tidak bertanggungjawab memiliki kesempatan untuk mengubah data dan atau menyadap. Oleh karena itu, perancangan sistem keamanan jaringan wireless yang terhubung ke internet harus direncanakan dan dipahami dengan baik.Standar jaringan nirkabel IEEE 802.11 yang menggunakan enkripsi WEP memiliki kelemahan yang memungkinkan seorang penyusup mengetahui kode enkripsinya. Berdasarkan latar belakang tersebut di atas, kami melakukan penelitian ini. Adapun tujuan penelitian ini adalah untuk mengetahui vulnerability atau celah keamanan pada jaringan WPA2-PSK dan untuk mengetahui fitur sistem operasi kali linux dalam menganalisis Router TP-Link Mercusys MW302R dalam keamanan jaringan WPA2-PSK. Metode untuk ujicoba dengan metode penetration testing. Metode Penetration testing yang kami gunakan menggunakan sistem operasi kali linux dengan tahapan: Planning and Preparation, Reconnaissance, Discovery, Analyzing information and risk, Active intrusion attempts, Final analysis, Report preparation. Berdasar hasil analisis dan pengujian terhadap sistem operasi pada jaringan yang menggunakan router Tp-Link Mercusys Mw302r, maka dapat ditarik kesimpulan bahwa port http dapat dieksploitasi oleh meterpreter melalui msfconsole pada kali linux dan setiap lalu lintas data pada jaringan, jika dilakukan proses scanning dan discovering selalu dan besar kemungkinan didapat vulnerability atau celah keamanan melalui port yang terbuka.

Mitra dari kegiatan Program Kemitraan Masyarakat (PKM) ini adalah pemilik usaha bakery di Malang Raya, yaitu Mery Bakery. Usaha Roti “Mery Bakery” yang beralamatkan di JL.L.A Sucipto Kecamatan Blimbing Kota Malang ini adalah milik ibu Menik. Berdasarkan analisis SWOT dilakukan, terdapat dua permasalahan utama, yaitu pemilik usaha bakery tersebut belum mempunyai media promosi online atau berbasis teknologi informasi dengan menggunakan media sosial misalnya blog atau instagram, karena masih menggunakan promosi penjualan langsung dan dari mulut ke mulut pada masyarakat sekitar saja. Padahal peluang meningkatkan penjualan dapat dilakukan dengan menggunakan media promosi online yang mudah, murah dan memiliki daya jangkauan pemasaran yang lebih luas, sehingga bisa mengembangkan pasar tidak hanya di wilayah sekitar saja, tetapi dapat memasarkan produksi bakery-nya ke seluruh wilayah Malang Raya melalui pemesanan online atau COD (cash on delivery). Selain permasalahan pemasaran, permasalahan kedua adalah peningkatan proses produksi terutama pembuatan varian rasa baru untuk roti, misalnya rasa abon sapi, sosis, telo ungu, selai apel, bawang bombay dan lainnya.Solusi yang ditawarkan untuk mengatasi permasalahan pemasaran, adalah pelatihan dan pendampingan pada ibu Menik tentang strategi pemasaran berbasis media sosial yang sesuai dengan karakteristik usaha bakery dan pelatihan yang dilakukan harus dapat digunakan secara berkelanjutan. Pelatihan meliputi peningkatan pengetahuan dan keterampilan tentang strategi pemasaran produk dan pemasaran berbasis teknologi informasi .

Matematika informatika yang sebelumnya disebut namanya sebagai matematika diskrit merupakan salah satu cabang ilmu matematika yang mengkaji objek-objek yang bersifat diskrit atau diskontinyu. Matematika menjadi pelajaran yang dianggap masih cenderung sulit dipahami bagi siswa SMK. Sehingga, materi ini diperlukan untuk cabang ilmu informartika seperti teknik komputer jaringan yang merupakan salah satu jurusan di SMK Az-Zahra Sepatan. Materi tersebut diperlukan karena komputer digital beroperasi secara diskrit dengan unit terkecil yang disebut bit atau binary digit. Belajar matematika berhubungan dengan bagaimana implementasinya untuk membuat suatu keputusan dalam penyelesaian atau pemecahan masalah. Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk mengembangkan model pembelajaran matematika di bidang informatika khususnya jurusan teknik komputer jaringan. Kegiatan ini akan menghasilkan luaran dalam bentuk jurnal untuk pembelajaran matematika informatika. Selain target luaran berupa jurnal ilmiah, kami berharap kegiatan ini memberikan dampak positif bagi audiens, seperti: Siswa menjadi lebih mudah dalam belajar, karena kebanyakan siswa lebih suka praktek langsung dibandingkan teori. Praktek langsung yang dimaksud yaitu dengan contoh kasus nyata yang terjadi di bidang teknik komputer jaringan seperti misalnya konfigurasi IP dan menghitung subnet. Kegiatan PkM Tersebut melibatkan 53 peserta, dimana peserta adalah siswa siswi kelas XII. Kegiatan didampingi oleh Wakasek dan Guru SMK Azzahra Sepatan. Kegiatan berlangsung dengan baik karena adanya feedback langsung antara nara sumber dan peserta pelatihan.
