Which of the following is a weakness associated with the use of symmetric, private keys...

The use of symmetric, private keys in WEP encryption is associated with several weaknesses, one of which is that the keys often remain unchanged on networks for extended periods. This can lead to security vulnerabilities because if an attacker manages to compromise a key, they can potentially gain access to the network and decrypt data for as long as the key remains unchanged.

References: The weakness of symmetric key encryption, particularly in the context of WEP, is that the key must be securely shared and, if compromised, can lead to significant security risks since the same key is used to encrypt and decrypt data123. This is exacerbated in WEP due to its flawed implementation of key management and lack of proper key rotation mechanisms.
