Post Welcome to the Gamers.com.nu Here are the general forum rules: 1. This is a privately owned forum. We reserve the right to accept, decline or revoke memberships. 2. The management reserves the right to make judgement calls. We can't write a rule for everything. If we see nonsense on the forum we will take care of it and let you know why. This is the "no nonsense" rule. 3. No content that is considered racist, obscene or objectionable will be tolerated. All such posts will be deleted without notice. This includes avatars. 4. No discussion of pirate games is tolerated anywhere on the forum and will result in a ban 5. You will not violate a persons privacy by publishing against someone's will information that is private and personal unless you have evidence of a crime or scam. Your post will be deleted if you cannot back up your claim. 6. Personal attacks on others will not be tolerated. We take politeness very seriously. You are welcome to challenge others points of view and opinions, but do so respectively and thoughtfully. 7. Create threads in the proper forum. Threads created in the wrong forum are subject to deletion. 8. Do not spam the forums, we encourage quality posts. Do not cut and paste your own posts, or those from other forums. Do not double/triple post if you want to add something to a previous post please use the edit function. 9. Do not promote your own website, company, or service in any of the forum categories. This includes starting a thread, or replying to a post. If a member is seeking assistance or looking for a certain type of product, the best way to offer your services is to send a PM. 10. Promoting other similar forums (or any forum that resembles the structure and/or content of Gamers.com.nu) in your posts, signatures, or in any way on the forum is not permitted. 11. Affiliate links of any type are not allowed in posts, signatures, or anywhere else on the forum. The Owner of this forum is the only one permitted to post affiliate links. 12. Your forum signature may not exceed 3 lines and 200 characters in length, and may contain no more than two links. Image sigs must not exceed 450x150 pixels. Violations of these rules may be corrected without warning. 13. Users may disagree with the decisions or actions of the moderators and/or administrators. However, disagreements, criticism and the like are not to be aired within the forums. Please feel free to PM the person directly rather than air your dirty laundry in public. 14. Any abuse towards our staff and/or management will result in an immediate ban. 15. Violation of the rules will result in a warning and possibly a ban, depending on the severity of the violation.

Wireless Network Security Basics

Wireless Network Security Basics

Wireless Networks are those in which the interconnection between devices is established without using wires. The nodes communicate using radio waves. The wireless adapter in a computer translates data in radio signals and transmit it. The wireless router receives the radio signals, decode it and sends the data to internet. Of course this process also works in reverse manner.
A wireless network is usually called as Wifi or WLan. The main advantages of Wireless Networks are that users are not bound to areas to plug into a Wall jack to connect to network and also it reduces the cost of cable used in Wired Networks.

The main disadvantage apart from network performance is lack of security. The wireless networks can be
easily compromised if they are not properly configured.

Basic Terminology

Service Set Identifier (SSID) :It is an alphanumeric string that differentiates the wireless networks .It can be
maximum of 32bit. There can be more than one network in a certain range or on a same channel, SSID
differentiates one from another. Simply it is the name of a network.

Wireless Access Point(WAP)

It is the point from where wireless network signals are generated. WAP is a device that receives radio signals from computers in network and send them to router.
It is the MAC address of WAP or wireless router. It is a unique 48 bit key.

Beacons :

These are wireless packets which are broadcasted to maintain the connectivity between WAP and the computers in network. The WAP broadcasts beacons from time to time to check connectivity with computers.

What is Wireless Equivalent Privacy (WEP)?

WEP is an encryption scheme used to encrypt the WiFi data streams. WEP encryption uses a 64bit or 128bit key.
A WEP uses the combination of an encryption key and Initialization Vector (IV). IV is any 24bit random number and is attached to encryption key to make it difficult to crack.64bit WEP encryption uses a 40bit key and 24 bit IV. Similary 128bit WEP encryption uses a 104 bit key and 24bit IV.
The advantages of WEP

1. Authenticating Clients

The users/clients connection to the wireless network need to enter the correct WEP key to gain access to network.

2. Privacy

It protects the wireless data by encrypting them and allowing decryption by users who have correct WEP key.

The WEP key can be easily cracked by an attacker because size of IV that is 24bit is very short.The vulnerability in WEP is that an IV which is randomly generated is repeated after certain number of packets as it is short (24bit) and less number of combinations are possible.

Due to this insecurity, Wi-Fi Protected Access(WPA) and WPA2 security protocols were released. They provide more security by generating complex and dynamic keys which are hard to crack. The method of creating IVs and encryption keys was improved. WEP,WPA,WPA2 are secure in increasing order.

Basic Security Measures for Wireless Networks :

1. MAC filtering- The MAC address is theoretically a unique 48bit address by which a network device is
recognised. The administrator might let the only the particular clients to connect to network by checking whether their MAC address is present in the list of registered MAC addresses or not.

The drawback of this security mechanism is that administrator need to keep changing the list of MAC address according to new clients connecting and clients which have not been in use for a long time. This security mechanism can be bypassed by attacker by spoofing his MAC with already a registered one.

2.Hiding SSID

Do not simply broadcast the SSID. It lures the attackers or War Drivers to break into the networks. Wireless devices can only connect to WAP if the SSID is known.

3. Using encryption Keys

Using an encryption scheme like WEP,WPA or WPA2 is must for Wireless administrators. A WEP doesn't matter how long it is, can be cracked in minutes. So WPA or WPA2 is recommended.

4. Intrusion Detection Systems(IDS)

Completely securing a wireless is hard. But is easy to moniter what is going on in a network. IDS monitors traffic and alerts the administrator when something unusual is happening or traffic matches any predefined pattern of attack. Many open source products like AisSnare, Snort-Wireless,WIDZ etc are available for the same purpose.
