))))) Quality performance The popularity of handheld devices is growing rapidly and thus has given option for PDAs. These devices are available at minimal reasonable price and hence produce new risks in security. In this both WLAN and PDAs, both of them possesses high risk like risk of password of connection, identification of weak spots, device that are being used such as devices with low quality carry more risk than authorised devices. Mobile phones now days are manufactured by many different companies which of them are of high quality where as some of them are of low quality. In above mentioned both devices the risk is as similar to mobile phones, these mobile phones can serve as a gateway for applications and attackers. Firstly the operating system which comes under architecture need to be test out and then only issues or faults will be seen after that issues related to security will be figured out. When there is a topic about mobile phones along with their comes Bluetooth and infrared which are attached to mobile phones and are used for transfer of files, videos, music etc. If attackers get access to Bluetooth of any devices then there will be massive chance of security vulnerabilities. Infrared is also another media for communication and its advantages are simple and minimal cost, requires low power, point to point connection, and reliability. Wireless security is a matter of concern and requires good strategies for security.
Over all this book deals with security issues, and way to mitigate risk, advantages and disadvantages of wireless devices and security issues related to them. The wide word internet has surpassed the way it was used in traditional market along with the door to possibilities for ecommerce.

It’s not been ten years that these small hand held devices got popularity having convenient factor as price and easily available. But these small devices has some limitations like battery, memory, screen sizes etc. which makes the way of developing new applications almost challenging.
