1. Introduction The Cisco 5540 Adaptive Security Appliance ASA is a best-of-breed product that provides perimeter security and remote access to users through VPN. This paper will discuss the firewall and VPN classifications and protocols of the Cisco 5540 ASA. The paper will discuss the strengths, weaknesses and effectiveness of the appliance and its architecture. 2.
This enhances usability and in some sense, creativity. Wireless internet isn’t really that hard to setup. You need an access point, a server, and a laptop. After that, it’s all a matter of configurations and you’re in. The only real complaint that we heard about Wi-Fi is that there are security issues.
Where it works? Freescale has wide portfolio of ZigBee-enabled ICs and low-power microcontroller (MCU) which forms an ideal platform for ZigBee-enabled network.

Moreover, what are the advantages of Bluetooth technology? These and many more will be discussed in the subsequent paragraphs. Bluetooth technology was created by Ericsson, a telecommunications vendor in 1994 as an alternative wireless in place of RS-232 a data cables.

Bluetooth technology could be enhanced to replace this wire-oriented technology to eliminate the needs to connect and transmit this data using Bluetooth technology.
The Personal Area Network (PAN) created can operate at a distance up to 100 meters (328 feet) depending on the individual device specifications. Short-range radio waves are transmitted at 2.4 to 2.485GHz using a signal that hops at 1600 hops/sec. A users’ private data is stored and they are able to transfer data with other devices while keeping that data from being publicly available. In order to pair devices securely, there must be an authentication process, key generation, and key acceptance. Paired devices can share voice, data, music, photos, videos, and other information wirelessly (Bluetooth Technology 101: Fast Facts).

Nowadays, people seek a simplest and fastest ways to send file and Bluetooth act as one of it. This is because the technologies have improved and Bluetooth also can upgrade by time. The speed, range and specification can be repaired and improved as long people using it. As a conclusion, Bluetooth is a connection between two device it is used worldwide.
Introduction Bluetooth Low Energy The Traditional Bluetooth had given us ability and also quickly connect to peripheral devices but Bluetooth Low Energy with the release the type of peripheral devices that connect have spilled over to medical and sports fields in remarkable ways. Then, we are use the smart phone and also tablet devices to connect the internet, stream audio on the car and also even in home entertainment systems. Extend the number of peripheral devices that connect will need for more efficient ways of doing so. Bluetooth Low Energy implement entirely new protocol stack along with new profiles and applications. Its core objective is to run for a very long time on a coin-cell battery.
Before the implementation of BlueTooth into cellular devices, cell phone users were either required to have a wired earpiece running to their phone, or use one of their hands to hold the phone to their ears. Bluetooth has become a vital part of corporate use because it allows for employees to excel in multitasking, making it one of the world’s most used wireless connection system. Cell phone manufacturers prefer BlueTooth to any other type of technology because of the low power consumption, less complication on the user’s behalf, and the ability to implement the technology cheaply. This technology has advantages over infrared transmitters due to the ability to leave the line of sight of either object whilst still maintaining a connection. This allows the user to leave the phone in his pocket while only pressing a small button on the headset.
Bluetooth is a wireless networking standard for your personal area that provides license-free operation in Europe, Japan, and the United States. What makes Bluetooth so special is its ability to create a wireless link between devices equipped with this new technology. Bluetooth opens us up to a new level of data communications. By making it possible to communicate wirelessly to any device equipped with a Bluetooth chip. Mobile phones can communicate with lap top computers, digital daily planners can be linked to personal computers and have e-mail down loaded to them the moment it is sent a multitude of possibilities are born.
PPP originally would negotiate the way it would provide Authentication between two entities before the two were actually connected, called the Link Establishment Phase (RFC 1661, 1994). Technology today must have peers connect to the authenticator first and then establish the authentication, authorization, and accounting (AAA) method that will be used. The authentication had to move from the Link Establishment Phase into a new standard. Thus EAP was developed as a new method of authentication negotiation (Sotillo, 2007). A very common example of EAP is wireless communications, the peer must connect to the authenticator to establish a connection, and then the EAP negotiation is initiated.
