2. Wired and Wireless Network
IEEE Wireless Networking Standards
Wireless Network Security
Wireless Network of NOUN Abeokuta Study Centre
Wi-Fi Protected Access (WPA & WPA2)
Summary

3. A wired network uses physical cables to send
data between different devices and computer
systems.
A wireless network is a technology that enables
an electronic network device to receive, transmit
and exchange data or connect to the internet
wirelessly through radio waves.
A wireless network facilitates mobility – It associates
data connectivity with user freedom of
movement through a simple pattern and enable
network mobility

4. IEEE Standard Frequency Speed Topology Transmission Range Access Method
802.11 2.4GHz 1 to 2Mbps Ad Hoc/Infrastructure 20ft Indoors CSMA/CA
802.11a 5GHz Up to 54Mbps Ad Hoc/Infrastructure 25 to 75ft Indoors CSMA/CA
802.11b 2.4GHz Up to 11Mbps Ad Hoc/InfrastructureUp to 150ft Indoors CSMA/CA
802.11g 2.4GHz Up to 54Mbps Ad Hoc/InfrastructureUp to 150ft Indoors CSMA/CA
802.11n 2.4/5GHz Up to 600Mbps Ad Hoc/InfrastructureAbove 175ft Indoors CSMA/CA

5. The wireless network radio waves allow anyone to
track packets traffic with the aid of “hacker’s tools”
to break the encryption and authentication of
wireless data.
The Wireless Network Security Features are:
1.Service Set Identifier (SSID)
2.Wired Equivalent Privacy (WEP)
3.Mac Address Filters (MAF)

7. The two recommended security approaches are:
WPA (Wi-Fi Protected Access)
WPA2 (Wi-Fi Protected Access, Version 2)
WPA also has two generations named
Enterprise (suitable for business environment)
Personal (suitable for home network)
The Encryption standards are:
Temporary Key Integrity Protocol (TKIP)
Advanced Encryption Standard (AES)
Pre-Shared Key (PSK): A key of 8-63 characters

8. 
Change all possible default router settings

Use encryption (WPA/WPA2)

Use long and complex keys/passphrases

Change router default user name and password

Change the internal IP subnet if possible

Change default name and hide broadcasting of the
Service Set Identifier (SSID)

None of the attack methods are faster or effective when
a larger passphrase is used.

Restrict access to your wireless network by filtering
access based on the MAC (Media Access Code)
addresses
