Tugas Nmap

Nmap adalah Tool untuk eksplorasi jaringan, secara ekslusif menjadi salah satu tool andalan yang sering digunakan oleh Administrator Jaringan, Pen-Test (IT Developer yg dibayar untuk mencari Hole pada System Jaringan)serta Attacker. Tool ini digunakan sebagaimana namanya yaitu Penjelajah System Jaringan (Network Mapper, Network Exploration Tool).

Dengan Nmap kamu bisa melakukan Probing (probe) keseluruh jaringan dan mencari tahu service apa yang aktif pada port yang lebih spesifik. Buka saja hanya itu tapi juga mencampur fingerprinting (Banner Grap) yang bisa membandingkan dan memberikan estimasi akan apa jenis Sistem Operasi (OS) target. Nmap juga mempunyai banyak kelebihan atau Flags yang akan memanipulasi bagaimana cara dia (Nmap) melakukan Scanning, kamu hanya perlu melakukan tcp()connect scanning yang akan membuat full connection ke host atau syn scanning juga biasa dikenal (a.k.a) Half Connection, testing Firewall atau mencari tahu apakan ada Firewall atau Packet Filter,Idle Scan yang akan melakukan Spoofing (menyembunyikan IP kamu) ke Host yang lain ataumemakai Decoy (host umpan) yang akan membuat JeJaK (trace) kamu semakin susah dilacak. Nmap kompetibel dengan Linux/BSD Family (Unix) dan Windows, walaupun aku akan menjelaskan penggunaan Nmap melalui Linux, tapi versi yang di Windows sama dengan yang di Linux.

Local Area Network

Local Area Network (LAN)

Tujuan dari jaringan komputer adalah untuk menghubungkan jaringan-jaringan yang ada dalam jaringan tersebut sehingga informasi dapat ditransfer dari satu lokawi ke lokasi yang lain. Karena suat perusahaan memuliki keinginan/kebutuhan yang berbeda-beda maka terdapat berbagai cara jaringan terminal-terminal dapat dihubungkan. Struktur Geometric ini disebut dengan LAN Topologies.

Terdapat enam Network Topologi yaitu :

 Star

 Mesh

 Ring

 Bustree

 Hybrid

Setiap topologi memuliki karakteristik yang berdeda-beda dan masing-masing juga memiliki keuntungan dan kerugian. Topologi tidak tergantung kepada medianya dan setiap topologi biasanya menggunakan media sbb :

- Twisted pair

- Coaxial cable

- Optical cable, atau

- Wireless.

Physical Topologi adalah bagaimana kabel digelar sedangkan Logical Topologi adalah bagaimana jaringan (network) bekerja pada ‘physical wiring’. Harus diingat bahwa representasi secara logical dari suatu topologi mungkin bias sangat berbeda dengan implementasi secara fisiknya (physical implementation).

Sebagai contoh semua workstation dalam suatu token ring, secara logical dihubungkan secara ring. Akan tetapi secara fisik setiap station dihubungkan (attached) ke ‘central hub’, seperti sebuah star topologi.

Transfer Control Protocol / Internet Protocol dan User Datagram Protocol

 TCP/IP dan UDP

TCP/IP TCP singkatan dari 'Transmission Control Protocol' dan hampir semua sistem operasi modern kompatibel dengan protocol ini. TCP adalah dasar dari koneksi, Hal ini berarti melakukan suatu koneksi langsung antara dua komputer untuk melakukan transfer data antara kedua host. Suatu paket mengandung header dan data gram, pada bagian header dari paket akan mengandung informasi penting tentang :

? ? Source Port 

? ? Destination Port 

? ? Sequence number 

? ? Acknowledgement number 

? ? Header Length (Standard 20 Bytes) 

? ? Flags (syn, ack, psh, fin, rst, urg) 

? ? Window size 

? ? Checksum 

? ? IP_v4 or IP_v6 

? ? Header Length 

? ? DSF 

? ? Total Length 

? ? Identification 

? ? Flags (Set Fragment bit or not) 

? ? Fragment Offset 

? ? TTL 

? ? Protocol (this case TCP) 

? ? Header checksum 

? ? Source IP 

? ? Destination IP

 

Jika anda ingin memahami bagaimana suatu koneksi dilakukan, bacalah dengan seksama ilustrasi berikut ini : 

Awalnya suatu paket dengan SYN-flag dikirim ke IP tujuan, tujuan akan memberikan respon dengan suatu ACK(SYN) flag atau suatu paket de ngan RST-flag. Akan saya jelaskan: SYN singkatan dari SYN -(synchronisation), yang digunakan untuk ‘memberitahukan' komputer tujuan suatu permintaan

melakukan koneksi, kalau diterima, maka permintaan tersebut akan dijawab dengan suatu paket ACK(SYN) flag. A CK singkatan dari ACK-(nowledgement). Setelah menerima paket dengan ACK(SYN) flag, komputer mengirim kembali suatu ACK memberitahukan host lain bahwa koneksi telah dibuat. Hal ini kita sebut sebagai "Three-Way-Handshake". Jika koneksi telah dibuat dan salah satu host ingin melakukan disconnect, akan dikirim suatu paket dengan FIN-flag diaktifkan. (FIN singkatan dari FINish). Tabel ini akan membuat hal ini lebih jelas:
