Which of the following are the countermeasures against WEP cracking? Each correct answer represents a part of the solution. Choose all that apply.

Changing WEP keys frequently limits the window of time an attacker has to capture enough initialization vectors (IVs) to statistically crack the key, since WEP's weakness is rooted in IV reuse and small IV space.

Using the longest key supported by hardware - typically 104-bit WEP instead of 40-bit - increases the key space and makes brute-force and statistical attacks significantly more difficult and time-consuming.

The SSID is a network name broadcast to identify the wireless network and is entirely separate from the WEP encryption key and IV mechanism, so changing its bit length has no effect on WEP cracking resistance.

Using a non-obvious, complex key reduces the effectiveness of dictionary-based and brute-force attacks against the shared WEP key, since weak or default keys are trivially guessed.
