What You Need To Know About Wireless Security

Wireless security is not much different from wired security, it is just as critical for your business as having a lock on the front door. When implementing wireless security, finding the balance between security, accessibility, and cost of ownership can be difficult. The biggest problem with wireless security is that network administrators fail to take the simplest of steps to ensure security, fail to change the default passwords and network name, and place access points in non-secure positions. An important step in wireless security is to connect your wireless access points to switches instead of hubs. With the constant emergence of new schemes, challenges and threats, wireless security is always needing to evolve and develop in new directions.

Wireless networks are vulnerable because they do not have the same physical boundaries that wired networks have. Wireless network security based on the IEEE 802 standard. Wireless security vulnerabilities have been widely publicized before and making traditional link-layer attacks readily available to anyone. Wireless security demands the juggling of technology and risk assessment.

Security is especially important if both public and municipal communications run on the same wireless network. Security standards have evolved with wireless networking from the introduction of Wired Equivalent Privacy (WEP) in 1997. Security concerns have caused some network managers to avoid installing wireless LANs (WLANs), regardless of the numerous benefits that they provide. Network managers need to provide to their end users with their freedom and mobility, without offering intruders access to the WLAN or the information sent and received on the wireless network. Security experts recommend that enterprises implement several layers of security across the network to mitigate threats.

Network managers need assurance that solutions are available to protect their WLANs from these security threats and that WLANs can provide the same level of security, manageability, and scalability offered by wired LANs. Network managers need to always keep one step ahead of the hackers by turning on their WLAN security features. Network managers reduce the risk from hackers by implementing proven security measures, and by using products and software developed by experts in network security. Networks built today should use WPA pre-shared keys at a minimum, support high-risk information, and conduct security reviews more frequently.

Encryption makes it much more difficult for a hacker to read the information that is being sent across a wireless network. Encryption is the process of making information unreadable through the unaided eye. Encryption is not perfect, but it can go a long way toward discouraging the casual hacker. Encryption requires a key exchange for the algorithms to have a starting point.

Wireless security is a critical issue in many environments, particularly where personal or financial information is transferred wirelessly. Wireless security is a work in progress, with evolving standards; and is an elusive threat to tackle because of the intentional signals that are continually transmitted through the airwaves. Because of all the issues, wireless security is going to remain a very hot topic and a very big issue for some time.
