Wireless Security

Security is not simply a button we push and then walk away feeling safe and secure. Instead, we go for a layered approach, understanding that the more layers we add, the more secure the network will be. In addition, we stress that each layer of security has a cost and that cost is paid in performance and maintainability. The more complex the security, that is, the more layers, the more work it is for a potential hacker to get in and the more work it is for us to maintain.

In this lecture, we discuss several ways to secure your wireless network and again, we opt for a layered approach. The layers that can be applied easily are:

MAC Filtering – Controlling access at the MAC layer. If the station can’t associate, it can’t gain access. MAC filtering can be circumvented by spoofing the MAC address of an allowed station so it is not very effective for seasoned hackers.

Encryption – WEP, WPA and WPA2 are some encryption protocols supported in RouterOS. By encrypting the data transmission, the network is greatly fortified.

Proprietary Protocols – using Nstreme or NV2 is a way to control access to the network. The hacker will have to use RouterOS to gain access and statistically this helps improve our odds of resisting attack.

Hiding the SSID – A very basic approach, nevertheless it is effective in keeping the existence of your wireless network away from most unsophisticated users but true hackers will not even be slowed down.
