Question

What is the current state of wireless security? What are the vulnerabilities? What are the threats?

Answer 1

Wireless Security : Wireless Security is a mechanism which prevent the unauthorized access of data or user to computer using wireless network. It provide security to protect data from unauthorized data breaches or illegal acts.

There are mainly two types of Wireless Standards:

I) WEP:  WEP password can often be cracked with computer devices in very less time. So This standard
is more vulnerable. There are many software tools are also available
to cracked the password and That's why this is notoriously known as weak security standard.

II) WPA: The Wi-Fi Protected Access (WPA and WPA2) protocol implements the majority of the IEEE 802.11i standard,
specifying security mechanisms for wireless networks.

Vulnerabilites:

1. Default WiFi routers. By default, wireless routers are shipped in an un-secured state. ...
2. Rogue Access Points
3. Wireless Zero Configuration
4. Bluetooth exploits
5. WEP Weaknesses
6. Clear Text Encryption Passwords
7. Malicious Code

Threats of wireless system:

There are some modes of unauthorized access of wireless system that given below;

i) Denial of Services: In this mode hacker continuously bombard bogus request, premature successful connection message etc.

ii) Man in middle attack: Man in the middle attack basically  a perpetrator positions himself in a conversation between a user and an application. These attack are  enhanced by software such as LANjack and AirJack.

iii) MAC Spoofing: MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device

iv) Ad hoc networks: It is improvised device to device network attack. This kind of attack is very dangerous for any computer network organization.
