What security measures should be integrated into a cryptocurrency exchange script?

Encryption:

Data Encryption: Use strong encryption to protect important information like user data and transaction details. This helps keep everything safe and secure from unauthorized access and potential threats. Always ensure that sensitive information is encrypted to maintain privacy and security.
SSL/TLS:Use SSL/TLS protocols to keep communication between the server and users safe. These protocols protect data as it travels from one place to another, ensuring that it cannot be easily intercepted or altered by unauthorized individuals.

Two-Factor Authentication (2FA):

Implement 2FA for logins and transactions. It adds a second step, like a text message code or app confirmation, making it harder for hackers to access accounts. This boosts security beyond just using passwords.

Cold and Hot Wallets:

Cold Wallets: Keep most of the money in offline storage to protect it from online dangers. This way, it is safer from hackers and cyber attacks. Online threats cannot reach funds stored offline, making it a secure way to manage money.
Hot Wallets: Employ active trading strategies with limited funds while ensuring their protection through strict access controls. This approach maximizes your trading potential while safeguarding your investments from unauthorized access or misuse. Implement robust security measures to manage your capital effectively and protect your assets during trading activities.

Regular Security Audits:

Regularly performing security audits and vulnerability assessments is essential for spotting and resolving potential security problems. These proactive steps reveal weaknesses, ensuring systems are protected against threats. Consistent evaluations help uphold strong security defenses, protect sensitive information, and prevent potential breaches before they happen.

DDoS Protection:

Implement Distributed Denial of Service (DDoS) protection to safeguard against attacks aimed at overloading the exchange's infrastructure.

Anti-Phishing Measures:

Deploy effective anti-phishing measures and educate users on spotting and avoiding phishing attempts. Continuously update security protocols, hold awareness workshops, and utilize simulated phishing tests to strengthen knowledge. Encourage a proactive approach to suspicious emails and links to safeguard sensitive information and prevent security breaches

Session Management:

Use strong session management practices to protect against session hijacking. Set session timeouts to automatically log out inactive users and use secure cookies to keep sessions safe. These steps help keep user sessions secure and private.

Access Controls:

Use role-based access controls (RBAC) to improve security by limiting who can access important system parts. This method makes sure users can only reach what they need for their job, reducing the chance of unauthorized actions and protecting sensitive data. Set permissions according to each user's role to keep the system secure.

Transaction Monitoring:

Monitor transactions to detect any suspicious activity. Set up automatic alerts to let you know if something unusual happens. This way, you can quickly catch any potential fraud or security problems and protect against unauthorized actions.

Rate Limiting and IP Whitelisting:

Set up rate limiting to stop users from overusing or abusing your system. Also, use IP whitelisting for important tasks to make sure only approved users can access them. This helps protect against unauthorized access and ensures your system remains secure.

Smart Contract Security:

To prevent problems, it’s important to test and check smart contracts carefully. This means closely reviewing the code to find and fix any issues. Thorough testing and expert audits help protect against security risks and failures, ensuring the contract works correctly and reliably.

Backup and Recovery:

Regularly back up your data and have a clear recovery plan. This ensures you can quickly return to normal if you experience data loss or security issues. Being prepared safeguards your work and keeps things running smoothly.

Regulatory Compliance:

Follow the rules and guidelines for safety and data protection in your field. Make sure you meet all the required standards to keep information secure and comply with laws. This helps prevent problems and ensures everything is done correctly. Keep yourself informed about the most recent regulations.

User Education:
