A device enabled with Wi-Fi,can connect to the internet via a wireless network access point. An access point (or hotspots) has a range of about 20 meters (65 ft) indoors and a greater range outdoors Wi-Fi: Wi-Fi networks are a shared network that makes it easier for others to eavesdrop on your communication. Devices are Stolen and tampered. Cryptography. Connection. security and privacy threatsSlide 12: Firewalls Secure browsing Secure internet transaction prevention of threats: Always use a Personal Firewall Set the firewall to deny ALL incoming connections Firewall: Secure Web Browsing use secure, encrypted sessions Secure Browsing: Secure Internet Transactions Use UCI’s VPN to encrypt your network traffic . Secure Internet Transaction: Insufficient bandwidth Security standards Power consumption Transmission interferences Human interface with device Potential health hazards DrawbacksSlide 17: Mobile computing is one of the greatest achievements of man but in the near future based on this mobile comuting even more discoverys will be made for the benefits of mankind. conclusion: Queries: THANK YOU M.ARAVINTH BY presented You do not have the permission to view this presentation.
