1. Implement a firewall:
Firewalls act as a barrier between your network and potential threats, preventing unauthorized access.
2. Encrypt data during transmission and storage:
Encryption ensures that sensitive data, such as credit card information, is unreadable to anyone without the proper decryption key.
3. Regularly update and patch software:
Regular updates and patches address vulnerabilities in your software, reducing the risk of exploitation by cybercriminals.
4. Use strong access control measures:
Implement strict access controls to limit who can access critical systems and data.
5. Restrict access to cardholder data:
Limit access to payment card data to only those who require it for their job.
6. Assign a unique ID to each person with computer access:
Individual user IDs help monitor and trace activities, enhancing security and accountability.
7. Track and monitor all access to network resources:
Real-time monitoring helps identify and respond to suspicious activities promptly.
8. Conduct security testing and vulnerability assessments:
Regular testing and assessments uncover weaknesses and areas that need improvement in your security infrastructure.
9. Develop and maintain secure systems and applications:
Building secure systems and applications from the ground up is essential to prevent vulnerabilities.
10. Create and maintain an information security policy:
A well-defined security policy provides guidelines for employees and helps ensure consistent compliance.
