Sistem Keamanan Komputer

TUGAS MAPSI

1Apa.yang dimaksud SI, jelaskan dan berikan contoh model dalam aplikasi dunia Usaha?

System informasi dibedakan menjadi 2 yaitu, system informasi manual dan system infomasi berbasis computer(CBIS)

Menurut Turban, McLean, dan Wetherber (1999) Sistem informasi adalah sebuah system informasi memgumpulkan,memproses, menyimpan,menganalisis, dan menyebarkan informasi untuk tujuan yang spesifik.
Menurut Wilkinson (1992) Sistem infomasi adalah kerangka kerja yang mengkoordinasikan sumber daya (manusia dan komputer) untuk mengubah masukan(input)menjadi keluaran(informasi), guna mencapai sasaran-sasaran perusahaan.
Jadi system informasi itu adalah hal untuk mempermudah user untuk mendapatkan infomasi.

Contoh system informasi
- system reservasi pesawat terbang
- system untuk menangani penjualan kredit kendaraan bermotor
- system biomerik
- system berbasis kartu cerdas(smart card)

2. Jelaskan maksud dari CBIS, apa manfaat dan tujuan CBIS bagi perusahaan!

CBIS adalah merupakan system pengolahan suatu data menjadi sebuah informasi yang berkualitas dan dapat dipergunakan sebagai alat bantu yang mendukung pengambilan keputusan, koordinasi dan kendali serta visualisasi dan analisis. CBIS = Hardware + Software + People + Procedure + Information
Manfaat dan tujuan CBIS Perusahaan yaitu mempermudah user.

3. Terdapat beberapa Metodologi Pengembangan Sistem, jelaskan kekurangan dan kelebihan dari metodologi yang ada!

a. Model sekuensial (pressman)(classic life cycle/waterfall model(dewitz)),terdiri dari tahapan perencanaan system(rekayasa sistem), analisis kebutuhan, desain, penulisan program, pengujian dan perawatan system
- kekurangan
- kelebihan
b. Model prototype (prototiyping model), dimulai dengan pengumpilan dan perbaikan, desain cepat, pembentukan prototype, evaluasi pelanggan terhadap prototype, perbaikan prototype dan produk akhir.
- kekurangan
- kelebihan
c. Rapid Application Development (RAD) model, dengan kegiatan dimulai pemodelan bisnis, pemodelan data, pemodelan proses, pembangkitan aplikasi dan pengujian.
- kekurangan
- kelebihan
d. Model evolusioner yang dapat berupa model incrementalmerupakan gabungan model sekuensial linier dengan prototyping(mis perngkat lunak pengolah kata dengan berbagai versi). Sedangkan model spiral menekan adanya analisis resiko. Jika analisis resiko menunjukkan ada kepastian terhadap kebutuhan, maka pengembangan system dapat dihentikan.
- kekurangan
- kelebihan
e. Teknik generasi ke-empat(4GL), dimulai dengan pengumpulan kebutuhan, strategi perancangan, implementasi menggunakan 4GL dan pengujian.
- kekurangan
- kelebihan

4. Mengapa dibutuhkan analisis dalam pengembangan suatu sistem, jelaskan dan sebutkan macam analisis yang dilakukan?

Macam-macam analisis system:
- Analisis kelayakan

Lima macam kelayakan dalam merancang system informasi yaitu keleyakan teknik, kelayakan ekonomi, kelayakan operasi, kelayakan hokum dan kelayakan jadwal.
- Analisis kebutuhan

Spesifikasi kebutuhan adalah spesifikasi yang dirinci tentang pengolahan data yaitu jumlah data yang harus diproses, waktu pengolahan saat data siap diproses sampai informasi yang dihasilakan. Spesifikasi ini digunakan untuk membuat kesepakatan dalam pengembangan system.

5. Perangkat apa saja yang digunakan dalam Network System, dan gambarkan satu model/bentuk sistem jaringan?

Kabel atau perangkat Wi-Fi, Ethernet card, hub atau switch, repeater, bridge, atau router.

Bentuk system jaringan MAN(Metropolitan Area Network)

Fly-half dies

Days turned into months
Month-year change
Sometime later I can not stand
Will miss the suspended

I wanted to meet with you dear
Releasing a deep longing
I've had enough to hold this longing
Become increasingly large

Did you miss your sense of this body
Want to kiss your brow
Hug your body
And whisper in your ear the word longing

I will wait for your loyal pobud
Faithful become your life partner
I'll keep this sacred love and I do not hurt
For only you who I loved in this world
