I don’t think an 8 character password would be effective at all; it seems too short for modern security needs.

I feel like using alphanumeric characters could help, but I'm not convinced it’s enough against rainbow table attacks.

I think using salt in the password is definitely a good countermeasure, but I'm not entirely sure if it's the only one needed.

Using an 8 character password? No way, that's way too short. The longer and more complex the password, the better protection against rainbow table attacks. I'd say salt is the way to go here.

I'm a little confused on this one. Is using alphanumeric characters really a countermeasure? I thought that was more about password complexity in general. I'll have to review this topic again.

Definitely go with using salt. That's the best way to make your passwords more secure against these kinds of attacks. The other options don't seem as effective.

Hmm, I'm not totally sure about this one. I know rainbow table attacks try to precompute hashes, so maybe using a hashed password could work? I'll have to think about it more.

Yes, that's correct! Salt adds random data to the password before hashing, making it harder for attackers to use precomputed rainbow tables.
