1 Introduction

Mobility: WLANs combine data connectivity with user mobility. This provides users with access to network anywhere in their organization. For example, users can roam from a conference room to their office without being disconnected from the LAN. This is impossible with wired networks.

Ease of Installation: Eliminating the need to deploy network cables in walls and ceilings, Installing WLANs is easy for novice and expert users alike.

Scalability: WLAN topologies are easy to change in various ways from peer-to-peer networks for a small group of users to full infrastructure networks for hundreds of users roaming over a broad area.

Wireless LAN is suitable for difficult-to-wire and frequently changing environments. It’s also an ideal solution for mobile workers to access network resource and for setting a temporary LAN when necessary

Wireless LANs can be set as “Ad-hoc” network and “Infrastructure” network. Unlike the “Ad-hoc network”, where users on the LAN send data directly to each other, the “Infrastructure” network includes an access point and users on the “Infrastructure” network send data to that dedicated access point. ADSL Wireless Router uses “Infrastructure” network as Wireless LANs. Each wireless LAN PC within the range of the access point can communicate with other wireless LAN PCs within the range.

Firewall

DoS is an abbreviation for Denial of Service. This occurs when a computer or network is overwhelmed to the point that it can no longer function normally. For example, a hacker may use fake IP addresses to accumulate numbers connections in orders to flood the server he wants to attack. The way TCP works is that a SYN packet is sent to the server from the client. After the server receives the SYN packet, a SYN-ACK is sent back to client. The server will then wait for the reply from the SYN-ACK. If the hacker sent hundreds or thousands of SYN packets to the server with bogus IP addresses, the server allocates computer and memory resources to establishing a connection since the server does not know a legitimate SYN message from a bogus message. By flooding the server with a large volume of requests, the server’s maximum capacity can be used by these bogus and useless connection attempts

SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just the headers of the packet, but also the packet content. It can then determine more about the packet than just its source and destination information. Moreover, stateful inspection firewalls also close off ports until a connection to the specific port is requested.
