Study Notes
Wireless Networks and Security
- GSM (2G) and 3G networks are used for various wireless applications such as laptops, cell phones, GPS, and biotechnology.
- Wireless networks facilitate mobility and enable connections without physical links.
- Security is essential in wireless networks to prevent unauthorized access and data theft.
- Security approaches include WEP, WPA, and WPA2, with WEP being a deprecated algorithm.
- WEP encryption uses 40/64 bit or 104/128 bit keys and can be vulnerable to attacks like ARP Spoofing and Firesheep.
- WPA/WPA2 encryption includes TKIP and AES, with the option for key renewal.
- Unsecured wireless networks are vulnerable to attacks and data interception.
- WEP, introduced in 1997, is a deprecated security algorithm with known vulnerabilities.
- WPA, released in 2004, replaced WEP and introduced TKIP and AES encryption.
- WPA2, an upgrade to WPA, is backward compatible and includes additional security measures.
- Unencrypted or exploitable wireless networks can lead to unauthorized access and malicious activities.
- Additional security measures include MAC address filtering, router firewall, and changing default settings.
Title: Radio Frequency Identification (RFID)
- RFID tags use integrated circuits and antennas to quickly identify items when scanned.
- RFID tags come in three types: passive, active, and semi-passive, with varying power supplies and capabilities.
- RFID solutions do not require line-of-sight access and can trigger security alarms if removed from their location.
- Automatic scanning and data logging is possible with RFID, and each tag can have a unique product code.
