Wi-Fi networks are extremely popular
Due to their usability, convenience and, especially, low implementation cost, Wi-Fi networks have become far more prevalent
among SMEs, the self-employed and private households than wired networks.
However, the Wi-Fi networks we regularly connect to are highly vulnerable because, in their original conception and design, and
also due to the limitations of older processors, simplicity and speed took priority over security features.
Factors that make Wi-Fi networks vulnerable
- Access with a pre-shared key (PSK), which is usually visible to the public and offers no ability to control or identify who is connected
- All the users have access with the same privileges and security policy
- It is easy to spoof other devices using MAC or IP spoofing techniques
- Most routers use the standard default configuration, which makes it easier for intruders because they all have similar parameters.
Local networks allow users to see who is connected. If the users who access the network cannot be identified because
they all connect with the same password or have no defined privileges, any user would be able to:
- See and access other devices
- Capture the traffic sent over the network
- Steal or tamper with the data transferred
- Spoof other users or devices
