Can you get money back from a bank if scammed?

I'm curious to know, is it possible to retrieve funds from a bank account if one has fallen victim to a scam? Are there specific steps or procedures that one should follow in such a situation? I understand that scams can be quite sophisticated and it's crucial to act swiftly, but how effective are banks in assisting their customers who have been deceived? And are there any preventative measures that can be taken to avoid falling into such traps in the future?
