Re: wireless port scan attacked ???
Xmas port scan involves an "odd" packet that is intentionally sent to an address where the packet's IP header has certain "unusual" flags set on it. Depending on the IP stack on the receiving host, it responds (or not) in a certain way which allows the originator to determine host characteristics.
This is very common on interfaces facing the Internet directly and it's not something you can stop. Port scans are a fact of life like pollution outside your home's front door.
A "PSK port scan" presumably is just detected attempts of someone trying to associate using an encryption key based on an incorrectly computed pairwise master key. Someone within radio range is probably trying different pre-shared key values to see if they can tap into your wireless connection. |
