How do I transfer money from Poloniex to bank?

Hello there, I'm curious about the process of transferring funds from Poloniex, a popular cryptocurrency exchange, to my bank account. Could you please walk me through the steps involved in this process? I'm particularly interested in knowing if there are any fees associated with the transfer, and how long it typically takes for the funds to reach my bank account. Additionally, are there any security measures I should be aware of to ensure a smooth and secure transaction? Thank you in advance for your help.
