7.3.5 Configuring Wireless Security

Nama : Oktaviandra Dwi Putra
NIM : 06486/2008
Pend.Teknik Informatika

7.3.5 Configuring Wireless Security

Step 1: Plan the security for your home network
a) 6 Langkah Pengamanan Dasar Jaringan :

1. Ubahlah Sistem ID (Identitas)
Biasanya suatu layanan nirkabel dilengkapi dengan suatu standart pengamanan identitas atau yang sering disebut SSID (Service Set Identifier) or ESSID (Extended Service Set Identifier). Sangat mudah bagi seorang hacker untuk mencari tahu identitas default dari suatu layanan atau jaringan, jadi sebaiknya Anda segera mengubahnya menjadi suatu identitas yang unik, yang tidak mudah ditebak orang lain.
2. Mematikan identitas pemancar
Dengan mengumumkan kepada umum bahwa Anda memiliki suatu jaringan nirkabel akan membuat para hacker penasaran untuk membobol jaringan nirkabel Anda. Mempunyai suatu jaringan nirkabel bukan berarti harus memberitahukannya kepada semua orang. Periksalah secara manual perangkat keras yang Anda pakai untuk jaringan nirkabel tersebut, dan pelajarilah bagaimana cara mematikannya.
3. Sediakanlah enkripsi
WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) dapat meng-enkripsi data Anda sehingga hanya penerima saja yang diharapkan dapat membaca data tersebut. WEP (Wired Equivalent Privacy) mempunyai banyak kelemahan yang membuatnya mudah disusupi. Kunci 128-bit hanya mempunyai tingkat pencapaian yang relatif rendah tanpa peningkatan keamanan yang signifikan, sedangkan untuk 40-bit atau 64-bit pada beberapa perlengkapan lainnya, mempunyai enkripsi yang sama baiknya. Dengan cara pengamanan yang standart saja pastilah tetap akan mudah bagi hacker untuk menyusup, namun dengan cara enkripsi ini pastilah akan membuat jaringan Anda lebih aman dari hacker. Jika memungkinkan, ada baiknya untuk menggunakan enkripsi WPA (peralatan yang lebih tua dapat diupgrade terlebih dahulu agar compatible dengan WPA). WPA dapat sangat menjanjikan dalam menjamin keamanan jaringan nirkabel Anda, namun masih tetap dapat dikalahkan oleh serangan DOS (denial of services).
4. Membatasi dari penggunaan traffic yang tidak perlu
Banyak router jaringan kabel maupun nirkabel yang dilengkapi firewalls. Bukan bermaksud mengedepankan firewalls, namun firewalls telah membantu dalam pertahanan keamanan jaringan. Bacalah petunjuk manual dari perangkat keras Anda dan pelajarilah cara pengaturan konfigurasi router Anda, sehingga hanya traffic yang sudah seijin Anda saja yang dapat dijalankan.
5. Ubahlah 'kata sandi' default Administrator milik Anda
Hal ini baik untuk semua penggunaan perangkat keras maupun perangkat lunak. Kata sandi default sangat mudah disalahgunakan, terutama oleh para hacker. Oleh karena itu sebaiknya ubahlah kata sandi Anda, hindari penggunaan kata dari hal-hal pribadi Anda yang mudah diketahui orang, seperti nama belakang, tanggal lahir, dan sebagainya.
6. Kunci dan lindungilah komputer Anda
Hal ini merupakan cara pengamanan terakhir untuk komputer Anda. Gunakanlah firewall, perangkat lunak Anti Virus, Zone Alarm, dan lain sebagainya. Setidaknya setiap satu minggu perbaharuilah Anti Virus yang Anda pakai.
(dna)

b) Apa resiko akses internet nirkabel

Kita semua tahu bahwa node jaringan nirkabel dapat memancarkan ke kisaran normal sekitar 300 meter, 300 meter, sehingga pemasangan kartu jaringan nirkabel untuk komputer apapun, dapat akses ke node jaringan nirkabel, dan dapat masuk ke jaringan nirkabel, jelas bahwa jenis metode akses mudah, mudah untuk membawa kepada ancaman keamanan jaringan nirkabel. Sebagai contoh, di 300 meter di Taiwan hacker komputer juga memiliki akses ke jaringan nirkabel Anda untuk mengontrol komputer Anda "setiap tindakan"; Walaupun jaringan nirkabel di kurangnya kerahasiaan informasi sebagai ketat kabel jaringan, tetapi Anda tentu tidak ingin serangan melanggar hukum sangat mudah untuk mengetahui keberadaan Anda dalam berbagai jaringan, seperti yang situs yang Anda kunjungi teman-teman, apa yang privasi dari pesan yang dikirim teman-teman di luar negeri, dll, adalah mungkin pengunjung ilegal tahu pasti.

Lebih serius adalah pengunjung ilegal dari jauh setelah Anda masuk ke dalam jaringan nirkabel Anda, akan sangat mudah untuk mencuri semua informasi account online Anda, sehingga akan memberikan keamanan yang lebih besar mengakibatkan kerugian. Jadi ada semua jenis jaringan nirkabel menghadapi risiko keamanan, Anda harus segera mengambil tindakan untuk mengambil tindakan penanggulangan, seperti melalui enkripsi atau verifikasi menggunakan teknologi identifikasi jaringan, untuk memastikan bahwa hanya Anda sebelum ditunjuk pengguna atau peralatan jaringan bisa ke jaringan nirkabel Anda , sementara yang lain ingin memaksa melalui berbagai teknologi jaringan nirkabel untuk mengakses operator jaringan nirkabel Anda, akan ditolak.


Step 8: Reflection
a) LinkSys WRT54G harganya yang murah dan cukup bisa diandalkan.
b) cara untuk membuat jaringan komputer yang aman
Jaringan komputer merupakan kumpulan dari beberapa komputer yang memliki koneksi satu dengan yang lain. Ketika semua komputer saling terhubung dalam suatu jaringan, keamanan merupakan hal yang harus diperhatikan. Fungsi keamanan adalah membuat jaringan komputer menjadi stabil, terstruktur, kuat serta mampu mengatasi berbagai gangguan. Logikanya, bila dalam suatu jaringan komputer ternyata memiliki sisi keamanan yang lemah tentu hal ini berdampak merusak kestabilan jaringan komputer tersebut. Banyaknya gangguan yang masuk akibat lemahnya keamanan yang dibuat bisa merusak kinerja transfer data pada jaringan komputer. Oleh karena itu, gangguan menjadi parameter untuk mengukur tingkat keamanan. Logikanya, sistem tersebut memiliki tingkat keamanan berdasarkan sering tidaknya mengalami gangguan, bukan?

Setelah memahami pentingnya keamanan dalam suatu jaringan maka kita dapat mengkaji lebih detail tentang keamanan jaringan komputer itu sendiri. Prinsip keamanan pada jaringan adalah hal yang sangat kompleks. bahwa keamanan jaringan komputer terdiri dari banyak bagian atau komponen. Sedangkan Tiap komponen itu masih kompleks. Hal ini setidaknya menggambarkan bahwa keamanan jaringan komputer ibarat puzzle yang besar dan rumit. Disamping banyak sekali standar keamanan dalam jaringan komputer, ternyata jumlah dan jenis serangan terhadap keamanan ikut bertambah tiap harinya. Hal ini membuat standar yang sudah dipakai harus dipertimbangkan kembali dan diubah lagi untuk mengimbangi jumlah dan jenis serangan yang selalu bertambah dan bervariasi.

Klasifikasi keamanan menurut David Icove, bahwa 4 tingkat yang harus diperhatikan :
1. Fisik / Physical Security
2. Manusia / Personel Security
3. Data, media , teknik dan komunikasi
4. Kebijakan dan prosedur

7.2.5 Configuring a Wireless Access Point
Step 1:
d)

Step 2: Log in to the multi-function device and configure the wireless network
e) SSID atau Service set identifier adalah tempat mengisikan nama dari access point yang akan disetting. Apabila klien komputer sedang mengakses kita misalnya dengan menggunakan super scan, maka nama yang akan timbul adalah nama SSID yang diisikan tersebut.

Step 3: Reflection
a) nirkabel, adalah teknologi yang menghubungkan dua piranti untuk bertukar data atau suara tanpa menggunakan media kabel.
b) Sebuah service set identifier (SSID) adalah urutan karakter yang unik nama jaringan area lokal nirkabel (WLAN). An SSID is sometimes referred to as a "network name." Sebuah SSID kadang-kadang disebut sebagai "nama jaringan." This name allows stations to connect to the desired network when multiple independent networks operate in the same physical area. Nama ini memungkinkan stasiun untuk terhubung ke jaringan yang diinginkan ketika beberapa jaringan independen beroperasi di wilayah fisik yang sama.
Each set of wireless devices communicating directly with each other is called a basic service set (BSS). Setiap set perangkat nirkabel berkomunikasi langsung satu sama lain disebut service set dasar (BSS). Several BSSs can be joined together to form one logical WLAN segment, referred to as an extended service set (ESS). Beberapa BSSs bisa bergabung bersama untuk membentuk satu segmen WLAN logis, disebut sebagai service set diperluas (ESS). A Service Set Identifer (SSID) is simply the 1-32 byte alphanumeric name given to each ESS. Service Set Identifer (SSID) adalah hanya nama alfanumerik 1-32 byte diberikan kepada setiap ESS.
For example, a departmental WLAN (ESS) may consist of several access points (APs) and dozens of stations, all using the same SSID. Misalnya, WLAN departemen (ESS) dapat terdiri dari beberapa akses point (AP) dan puluhan stasiun, semua menggunakan SSID yang sama. Another organization in the same building may operate its own departmental WLAN, composed of APs and stations using a different SSID. Organisasi lain di gedung yang sama dapat beroperasi WLAN departemen nya sendiri, terdiri dari AP dan stasiun menggunakan SSID yang berbeda. The purpose of SSID is to help stations in department A find and connect to APs in department A, ignoring APs belonging to department B. Tujuan dari SSID adalah untuk membantu stasiun di departemen A menemukan dan terhubung ke AP di Sebuah departemen, mengabaikan AP milik departemen B.
Each AP advertises its presence several times per second by broadcasting beacon frames that carry the ESS name (SSID). Setiap AP mengiklankan kehadirannya beberapa kali per detik oleh penyiaran frame suar yang membawa nama ESS (SSID). Stations can discover APs by passively listening for beacons, or they can send probe frames to actively search for an AP with the desired SSID. Stasiun dapat menemukan AP secara pasif mendengarkan beacon, atau mereka dapat mengirim frame probe untuk secara aktif mencari sebuah AP dengan SSID yang diinginkan. Once the station locates an appropriately-named AP, it can send an associate request frame containing the desired SSID. Setelah stasiun menempatkan sebuah AP tepat-nama, dapat mengirim permintaan asosiasi frame yang berisi SSID yang diinginkan. The AP replies with an associate response frame, also containing SSID. AP balasan dengan kerangka respon asosiasi, juga mengandung SSID.
Some frames are permitted to carry a null (zero length) SSID, called a broadcast SSID. Beberapa frame yang diperbolehkan untuk membawa null (nol panjang) SSID, disebut SSID broadcast. For example, a station can send a probe request that carries a broadcast SSID; the AP must return its actual SSID in the probe response. Sebagai contoh, stasiun dapat mengirim permintaan penyelidikan yang membawa SSID broadcast, AP harus kembali SSID sebenarnya dalam respon probe. Some APs can be configured to send a zero-length broadcast SSID in beacon frames instead of sending their actual SSID. Beberapa AP yang dapat dikonfigurasi untuk mengirim broadcast SSID nol-panjang dalam bingkai suar daripada mengirim SSID sebenarnya mereka. However, it is not possible to keep an SSID value secret, because the actual SSID (ESS name) is carried in several frames. Namun, tidak mungkin untuk menjaga rahasia nilai SSID, karena SSID sebenarnya (ESS nama) dilakukan dalam beberapa frame

Step 3: Convert host IP addresses
1. Computer hosts usually have two addresses, an Internet Protocol (IP) address and an Ethernet Media Access Control (MAC) address. For the benefit of humans, the IP address is normally represented as a dotted decimal notation, such as 135.15.227.68. Each of the decimal octets in the address or a mask can be converted to 8 binary bits. Remember that the computer only understands binary bits. If all 4 octets were converted to binary, how many bits would there be?
Jawab:

jika jumlah semua ada 4 oktet maka ada 32 bit yang terbentuk karena 1 oktet terdiri dari 8 bits.

1. IP addresses are normally shown with four decimal numbers ranging from 0 to 255 and separated by a period. Convert the 4 parts of the IP address 192.168.10.2 to binary.



Decimal Binary
192 11000000
168 10101000
10 00001010
2 00000010s
1. Notice in the previous problem how the 10 converted to only four digits and the number 2 converted to only two digits. When IP addresses can have any number from 0 to 255 in each position, eight digits are normally used to represent each number. In the previous example, eight digits were needed to convert 192 and 168 to binary, but 10 and 2 did not need as many digits. Normally 0s are added to the left of the digits to have eight digits in binary for each IP address number. The number 10 would be shown as 00001010. Four extra zeros are added to the front of the other four binary digits.
2. On the calculator in Binary mode, enter the digits 00001010 and select the Dec radio button.
3. Which decimal number is equivalent to 00001010?
Jawab:

00001010 ekuivalen dengan 10 pada decimal

1. Did adding “leading” zeros affect the number any?
Jawab:

Tidak karena 0 di depan tidak mempunyai pengaruh di dalam pengkonversian.

1. What would the number 2 (in the previous example) be if you were to make it eight digits?
Jawab:

karena pada IP address satu octet harus berisikan 8 digit bilangan biner.

Step 4: Convert host IP subnet masks
1. Subnet masks, such as 255.255.255.0, are also represented as dotted decimal. A subnet mask will always consist of four 8-bit octets, each one represented as a decimal number. With the exception of decimal 0 (all 8 binary zeros) and decimal 255 (all 8 binary ones), each octet will have some number of ones on the left and some number of zeros on the right. Convert the 8 possible decimal subnet octet values to binary.
Decimal Binary
0 00000000.00000000.00000000.00000000
128 11111111.11111111.00000000.00000000
192 11111111.11111111.11111111.00000000
224 11111111.11111111.11111111.00000000
240 11111111.11111111.11111111.00000000
248 11111111.11111111.11111111.00000000
252 11111111.11111111.11111111.00000000
254 11111111.11111111.11111111.00000000
255 11111111.11111111.11111111.11111111
1. Convert the four parts of the subnet mask 255.255.255.0 to binary.
Jawab:

11111111.11111111.11111111.00000000

Step 5: Convert broadcast addresses
1. Computer hosts and network devices use broadcast addresses to send messages to all hosts. Convert the following broadcast addresses.

Address Binery
IP broadcast255.255.255.255 11111111.1111111.11111111.11111111
MAC broadcastFF:FF:FF:FF:FF:FF 11111111.1111111.11111111.11111111
Step 6: Convert IP and MAC addresses for a host
1. Click the Start button, select Run, type cmd, and press Enter. From the command prompt, type ipconfig /all.

1. Make a note of the IP address and physical address (also known as a MAC address).
IP Address:
Jawab:

IP addressnya adalah 192.168.193.71

MAC Address:
Jawab:

MAC addresnya adalah 00-17-C4-23-43-FE

1. Using the calculator, convert the four numbers contained in the IP address to binary.

Decimal Binary
192 11000000
168 10101000
193 11000001
71 01000111
1. The MAC or physical address is normally represented as 12 hexadecimal characters, grouped in pairs and separated by dashes (-). Physical addresses on a Windows-based computer are shown in a format of xx-xx-xx-xx-xx-xx, where each x is a number from 0 to 9 or a letter from a to f. Each of the hex characters in the address can be converted to 4 binary bits which is what the computer understands. If all 12 hex characters were converted to binary, how many bits would there be?
Jawab:

Jika ada 12 karakter hexadecimal maka akan ada 96 bilangan biner yang terbentuk.

1. Convert each of the hexadecimal pairs to binary. For example, if the number CC-12-DE-4A-BD-88-34 was the physical address, convert the hexadecimal number CC to binary (11001100). Then convert the hexadecimal number 12 to binary (00010010) and so on. Be sure to add the leading zeros for a total of 8 binary digits per pair of hex digits.


Hexadecimal Binery
CC 11001100
12 00010010
DE 11011110
4A 01001010
BD 10111101
88 10001000
34 00110100
Step 7: Manipulate powers of 2 to determine the number of hosts on a network
Binary numbers use two digits, 0 and 1. When you calculate how many hosts can be on a subnetwork, you use powers of two because binary is being used. As an example, we have a subnet mask that leaves six bits in the host portion of the IP address. In this case, the number of hosts on that network is 2 to the 6th power minus 2 (because you need a number to represent the network and
1. number that can be used to reach all the hosts—the broadcast address). The number 2 is always used because we are working in binary. The number 6 is the number of bits that are used for the host bits.
2. On the calculator, in Dec mode, input the number 2. Select the x^y key, the key which raises a number to a power. Input the number 6. Click on the = key, press Enter on the keyboard, or press the = key on the keyboard—all give the total. The number 64 appears in the output. To subtract two, click on the minus (-) key and then the 2 key followed by the = key. The number 62 appears in the output. This means 62 hosts could be utilized.
3. Using the previously described process, determine the number of hosts if the following number of bits are used for host bits.

No. of Bits Used forHosts No. of Hosts
5 30 hosts
14 16382 hosts
24 16777214 host
10 1022 hosts
1. Using a similar technique as learned previously, determine what 10 to the 4th power equals.
Jawab:

Hasilnya adalah 9998

1. Close the Windows Calculator application.

Step 8: (Optional) Determine the network number and number of hosts based on subnet mask
1. Given the IP network address of 172.16.203.56 and a subnet mask of 255.255.248.0, determine the network portion of the address and calculate how many hosts can be created from host bits left.
2. Start by converting the 4 octets of the decimal IP address to binary and then convert the decimal subnet mask to binary. Remember to include leading zeros when converting to binary in order to make a total of 8 bits per octet.

Decimal IP addressand subnet mask Binary IP address and subnet mask
172.16.203.56 10101100.00010000.11001011.00111000
255.255.248.0 11111111.11111111.11111000.00000000
1. Align the 32 bits of the subnet mask to the 32 bits of the IP address and compare them. The bits in the IP address that align with the ones bits in the subnet mask represent the network number. What is the binary and decimal network number for this IP address? Determine the binary address first (include all 32 bits) and then convert it to decimal. Binary network address:
Jawab:

Decimal network address:
Jawab:

172.16.200.0
1. How many ones bits are in the subnet mask?
Jawab:

Subnetmask = 2n = 23=8
1. How many bits are left for host bits?
Jawab:

Host = 2n-2= 25-2= 30

1. How many hosts can be created with the bits left?
Jawab:

Host =2n-2= 211-2= 2046

Step 9: Reflection
