Passive Attacks 2 Jamming Attacks 3 Active Attacks 4 Dictionary building or Table Attacks 5 Man in the Middle Attacks Passive Attacks There s no way to detect a passive attack because the hacker is not breaking into your network He is simply listening eavesdropping if you will to the information your network broadcasts There are applications easily available on the Internet that can allow a person to listen into your wireless network and the information it broadcasts Information such as MAC addresses IP addresses usernames passwords instant message conversations emails account information and any data transmitted wirelessly can easily be seen by someone outside of your network because it is often broadcast in clear text Simply put any information transmitted on a wireless network leaves both the network and individual users vulnerable to attack All a hacker needs is a packet sniffer software available on the Internet along with other freeware or shareware hacking utilities available on the Internet to acquire your WEP keys and other network information to defeat security Jamming Attacks Jamming Attacks when a powerful signal is sent directly into your wireless network can effectively shut down your wireless network This type of attack is not always intentional and can often come about simply due to the technology This is especially possible in the 2 4 GHz frequency where phones baby monitors and microwave ove

Changing your SSID regularly will force any hacker attempting to gain access to your wireless network to start looking for that new SSID With these three steps in mind please remember that while SSIDs are good for segmenting networks they fall short with regards to security Hackers can usually find them quite easily 6 MAC addresses Enable MAC address filtering if your wireless products allow it MAC address filtering will allow you to provide access to only those wireless nodes with certain MAC addresses This makes it harder for a hacker using a random MAC address or spoofing faking a MAC address 7 Firewalls Once a hacker has broken into your wireless network if it is connected to your wired network they ll have access to that too This means that the hacker has effectively used your wireless network as a backdoor through your firewall which you ve put in place to protect your network from just this kind of attack via the Internet You can use the same firewall technology to protect your wired network from hackers coming in through your wireless network as you did for the Internet Rather than connecting your access point to an unprotected switch swap those out for a router with a built in firewall The router will show the access point coming in through its WAN port and its firewall will protect your network from any transmissions entering via your wireless network 41 PCs unprotected by a firewall router should at least run
