Supported Security – Applications in use

In today’s network landscape, securing the client side for end devices is crucial. Wireless networks are inherently vulnerable, as data is transmitted through the air, making it essential to implement robust security measures and understand the security capabilities of each device. In this lesson, I’ll explore various security standards supported by wireless devices and delve into the types of applications used on these networks. This will help network administrators make informed decisions about network setup and maintenance, ensuring both security and optimal performance.

1. Importance of Security in Wireless Networks

Wireless networks transmit data over radio waves, which means that anyone within range can potentially intercept data if it’s not properly secured. Unlike wired networks, where physical access is typically required to breach security, wireless networks expose data to the broader environment. Therefore, it’s crucial to understand and implement security protocols effectively to protect data integrity and privacy.

2. Security Protocols for Wireless Devices

WPA and WPA2

Two primary security protocols are commonly used on wireless networks: WPA (Wi-Fi Protected Access) and WPA2. WPA2 is highly recommended as it provides robust encryption and security features that help protect wireless data from unauthorized access. However, not all devices support WPA2. Older devices, such as some barcode scanners or legacy mobile phones, may only support WPA, which offers a lower level of security.

When dealing with devices that only support WPA, network administrators should inform the business owner of the potential security risks associated with using outdated protocols. Encouraging clients to upgrade these devices to WPA2-compatible models is essential. Using WPA on devices creates security vulnerabilities, as the protocol is more susceptible to breaches. In many cases, updating the hardware is a cost-effective solution for long-term security.
