firewall policies can be configured for the WAN‚ LAN and VLANs that we may implement. This is important as different user groups will need different types of access to the WAN. For example: the public wireless hotspot will need much more protection than the operations side in respect to what they can and cannot access. The Cisco IOS firewall also protects SIP which is the voice protocol. This is very important for our future voip needs. Wireless LAN: Lan will use WPA2 authentication for all wireless

TYPES OF NETWORKING A computer network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate‚ route and terminate the data are called network nodes.[1] Nodes can include hosts such as servers and personal computers‚ as well as networking hardware. Two devices are said to be networked

Multi-Layered Security Plan When developing a multi-layered security plan‚ you must look at each of the seven domains of the IT infrastructure and increase security on each of those domains. The seven domains are user domain‚ workstation domain‚ LAN domain‚ LAN to WAN domain‚ WAN domain‚ and remote access domain. Increasing the security on each of those seven domains will increase the overall security of the system and create a multi-layered security plan. In the user domain‚ one of the easiest ways

Activity 1 What is the difference between a traditional LAN and a wireless LAN? Instead of cable connections in traditional LAN the Wireless LAN has wireless router connected to the server and wireless receiver on each host. Wireless router has a limited coverage but could be extended by wireless repeaters.

Conception: The Origin of a Story The origin of a story may come from a plethora of triggers in life such as a notebook‚ memory‚ or even pure intuition. In Kingston’s novel‚ The Woman Warrior‚ she primarily uses her memory to recall the legend of Fa Mu Lan‚ a Chinese girl who took her father’s place in battle illegally (21).
