25 Appendix B: Wireless Security A Brief Overview Wireless-B Ethernet Bridge Appendix B: Wireless Security A Brief Overview Whenever data—in the form of files, e-mails, or messages —is transmitted over your wireless n etwork, it is open to attacks.
26 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge But even WEP has its problems. WEP’s encryption algorithm is referred to as “simple”, which also means “weak”, because the technology that scrambles the wireless signal isn’t too h ard to crack for a persistent hacker.
27 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge Active Attacks Hackers use Active Attacks for three purposes: 1) st ealing data, 2) using your network, an d 3) modifying your network so it's easier to hack in the next time.
28 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge examples below, your implementation and ad ministration of network security measures is the key to maximizing wireless security. No preventative measure will guaran tee network security but it will make it more difficult for some one to hack into your network.
29 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge 5) SSID There are a few things you can do to make your SSID more secure: a. Disable broadc ast b. Make it unique c. Change it often Most wireless networking devices will give you the option of broadcasting the SSID.
30 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge PCs unprotected by a firewall router should at leas t run firewall software, and all PCs should run up-to-date antiviral software. 8) WEP Wired Equivalent Privacy (WEP) is often looked upon as a panace a for wireless security concerns.
31 Appendix B: Wireless Security What Are the Risks? Wireless-B Ethernet Bridge The solution, then, is to segment your network up into multiple groups. If your network had 80 users and you used four WEP keys, a hacker would have access to o nly ¼ of your wireless network resources.
