Peralatan untuk LAN

Posted by Hamba Allah 03.09, under | No comments

Setelah lama tidak posting gara-gara tugas yang menumpuk dari dosen akhirnya ane bisa jg posting, hehehe langsung aja, untuk membuat sebuah LAN (Local Area Network) diperlukan beberapa peralatan diantaranya adalah :1. Hubs, digunakan sebagai concentrator dalam jaringan juga sebagai penguat sinyal.

2.Bridges, memiliki fungsi serupa dengan HUB tetapi memeliki kelebihan yaitu kemampuan untuk memilih dameneruskan sebuah data (Forward Intelligent)


3.Switches, sama dengan bridge tetapi memiliki lebih banyak port

4.Routers, berfungsi sebagai penghubung dari beberapa LAN serta menyediakan routing (jalur dari satu network ke network yang lainnya).
Semoga bermanfaat ..

Tingkatan Hacker

Posted by Hamba Allah 10.33, under | No comments

Tingkatan seorang hacker :
1. Elite
Ciri-ciri : mengerti sistem operasi luar dalam, sanggup mengkonfigurasi & menyambungkan jaringan secara global, melakukan pemrogramman setiap harinya, effisien & trampil, menggunakan pengetahuannya dengan tepat, tidak menghancurkan data-data, dan selalu mengikuti peraturan yang ada. Tingkat Elite ini sering disebut sebagai ‘suhu’.

2. Semi Elite
Ciri-ciri : lebih muda dari golongan elite, mempunyai kemampuan & pengetahuan luas tentang komputer, mengerti tentang sistem operasi (termasuk lubangnya), kemampuan programnya cukup untuk mengubah program eksploit.

3. Developed Kiddie
Ciri-ciri : umurnya masih muda (ABG) & masih sekolah, mereka membaca tentang metoda hacking & caranya di berbagai kesempatan, mencoba berbagai sistem sampai akhirnya berhasil & memproklamirkan kemenangan ke lainnya, umumnya masih menggunakan Grafik User Interface (GUI) & baru belajar basic dari UNIX tanpa mampu menemukan lubang kelemahan baru di sistem operasi.

4. Script Kiddie
Ciri-ciri : seperti developed kiddie dan juga seperti Lamers, mereka hanya mempunyai pengetahuan teknis networking yang sangat minimal, tidak lepas dari GUI, hacking dilakukan menggunakan trojan untuk menakuti & menyusahkan hidup sebagian pengguna Internet.

5. Lamer
Ciri-ciri : tidak mempunyai pengalaman & pengetahuan tapi ingin menjadi hacker sehingga lamer sering disebut sebagai ‘wanna-be’ hacker, penggunaan komputer mereka terutama untuk main game, IRC, tukar menukar software prirate, mencuri kartu kredit, melakukan hacking dengan menggunakan software trojan, nuke & DoS, suka menyombongkan diri melalui IRC channel, dan sebagainya. Karena banyak kekurangannya untuk mencapai elite, dalam perkembangannya mereka hanya akan sampai level developed kiddie atau script kiddie saja.
