Wi fi security
This document discusses wireless network security and social networks. It begins by describing different types of wireless networks like personal area networks and wireless local area networks. It then notes that the weakest point of wireless networks is their vulnerability since the information is transmitted over unprotected airwaves and mobile devices can be lost or stolen. The document outlines some basic security concepts for wireless communication like privacy, authentication, integrity, availability and access control. It provides examples of security threats on social networks and public WiFi networks. It concludes by emphasizing the integration of different wireless approaches and the need for security concepts like privacy and authentication on wireless networks.

- 8. Basic security forcommunication Privacy Authentication Integrity and non-Repudiation Availability and Access Control
- 9. Privacy Confidentially The intended recipientsknow what was being sent but unintended parties cannot determine what was sent. Required some encryption at the sender and required some decryption at the receiver
- 10. Authentication Confirms the identityof the other party in the communication Assures that The claimed sender is the actual sender The claimed receiver is the actual receiver
- 11. Integrity and Non-repudiation Dataintegrity Data is transmitted from source to destination without undetected alteration Non- repudiation Prove that a received message came from a claimed sender
- 12. Availability and AccessControl Ensure availability of resources for the intended users Controls access to resource
