Wireless networking is one of the most popular and fastest growing technologies on the market today. From home networks to enterprise-level wireless networks, people are eager to take advantage of the freedom and convenience that wireless networking promises. However, while wireless networking is convenient, it is not always deployed securely. Insecure wireless networks are found in people’s homes and in large corporations. Because of these insecure deployments, penetration testers are often called in to determine what the security posture of an organization’s wireless network is, or to verify that a company has deployed its wireless network in a secure fashion.
A wireless network allows devices to stay connected to the network but roam untethered to any wires. Access points amplify Wi-Fi signals, so a device can be far from a router but still be connected to the network. When you connect to a Wi-Fi hotspot at a cafe, a hotel, an airport lounge, or another public place, you’re connecting to that business’s wireless network.
Advantages of Wireless Networks
– It provides clutter-free desks due to the absence of wires and cables.
– It increases the mobility of network devices connected to the system since the devices need not be connected to each other.
– Accessing network devices from any location within the network coverage or Wi-Fi hotspot becomes convenient since laying out cables is not needed.
– Installation and setup of wireless networks are easier.
-New devices can be easily connected to the existing setup since they needn’t be wired to the present equipment. Also, the number of equipment that can be added or removed to the system can vary considerably since they are not limited by the cable capacity. This makes wireless networks very scalable.
– Wireless networks require very limited or no wires. Thus, it reduces the equipment and setup costs.
