Encryption Explained

Encryption

Comments

None

Totally Insecure.  No security at all.  Anyone with a wireless card can connect. About 12% of Wifi users fall into this category.

WEP

Very Insecure.  Requires a password to connect which will discourage casual users, but password can be recovered automatically in minutes by anyone using freely available software.  A staggering 40% of Wifi users fall into this category

WPA/WPA2

Generally Considered Secure. Has some limited vulnerabilities but they do not allow the key to be recovered and automatic tools are not freely available.

 

Why are so many wireless networks still insecure?

1. Configuration is complicated.  Wireless security can be difficult to configure. Users can be reluctant to change anything once the network is initially up and running with the default settings.

2. Default Settings.  Traditionally, manufacturers supply routers with standard settings which have the security switched off, possibly to make life easier for the average user. 

3. False Sense of Security.  A user may falsely believe that their network is secure because new devices require a password to gain access. WEP encryption requires a password, although it has been considered insecure since 2001.

4. Wireless Installations by Non-Specialist Companies.  Small businesses who outsource their IT support to companies that do not offer secure wireless networking will be unaware of the risks that they are taking. They will not realise that although their network is up and running, the company who has installed it may not have addressed or fixed any security issues.
