u8.5 Wifi Security Issues

u8.5 Wifi Security Issues

1. The risk of unauthorised stations associating with an access point or intercepting traffic is clearly the biggest risk with a wireless LAN.

2. Evil twin access point

   • Attacker uses an Ap with the same SSID as a target AP and gets stations to connect
     • Attacker can forward all data to the original AP and record it for analysis

3. Access point configuration

   • All AP's from the same manufacturer come with default settings
     • IE: Default admin credentials, enabled protocols, SNMP, web interfaces etc
     • If the default settings are not changed its easier for an attacker to compromise the AP

4. Rouge AP's and Ad-hoc Networks

   • Adding an unauthorised AP to a network
     • Attacker can connect to that AP at any time to connect to the underlying network

5. Denial of service

   • Accidental or deliberate
   • Caused by interference with the signal

6. HUB broadcasts

   • If an AP is connected to a network hub, any data that is transmitted by any device connected to the network hub will also be broadcast by the AP onto the wireless LAN segment.
