Is OKX secured?

Could you please elaborate on the security measures implemented by OKX to safeguard its users' funds and data? I'm particularly interested in their approach to encryption, multi-signature wallets, and how they handle potential threats such as hacking attacks and phishing scams. Furthermore, I'd like to know if they have a proven track record of protecting their platform against such incidents, and if they offer any additional security features for users to enhance their own protection.
