1. To protect cardholder data, install and maintain a firewall configuration
2. Do not use defaults provided by the vendor for system passwords and other parameters of security.
3. Protect cardholder information that has been processed.

Include data retention and disposal policies, procedures and processes to ensure that it is always up-to-date and accurate. Some data, such as the magnetic strip content, card verification number, or personal identification number, should never be stored. Encryption should be used to encrypt the information of the cardholder.

4. Encrypt cardholder data transmission through open, public networks.

Internet, wireless technologies such as Bluetooth, GPRS and satellite communications are examples of this.

5. Use and update anti-virus software or programmes on a regular basis.

Secure malware networks and upgrade antivirus programmes to block viruses, worms and trojans on a regular basis. Unless absolutely necessary, antivirus tools should be implemented, maintained and maintained.

6. Build and manage stable software and systems.

This means that software updates are checked and software is kept up-to-date at all times to protect against the latest vulnerability.

7. Restrict access to cardholder data by business need-to-know.

Systems and processes need to be put in place for this data to be accessed by WHO and WHY they need access. Access should only be available to individuals who need it to perform their role.

8. Assign a unique ID to each person with computer access.

This means making sure that you know who is accessing what at any time, so that you can always make sure that in specific systems and components only people with proper authorization are allowed. One way to ensure proper authorization is to use two-factor authentication to enhance safety, such as using smart cards, tokens or biometrics.

9. Restrict physical access to cardholder data.

Data loss is also possible due to physical security breaches, so care should be taken to ensure limited and monitored access to physical records. Server rooms and data centres should be restricted, media should be destroyed, and data-carrying devices should be protected and monitored.

10. Track and monitor all access to network resources and cardholder data.

To detect and minimise the risk of data breach, logging all access is required. Safe and managed audit trails should be enforced to record all user activities including data access, permissions, invalid login attempts, and changes to security mechanisms such as object deletion. All of these reports should be updated periodically.

11. Regularly test security systems and processes.

Penetration testing is an important part of the resources of the IT security team and should be conducted regularly, as well as after any major changes to the network.

12. Maintain a policy that addresses information security for employees and contractors.

Review it twice a year and update it to any new risk environment. To identify any risks or weaknesses, a risk assessment should be undertaken to allow the strategy and incident response plan to be established. To order to share and update personnel of any new security protocol, an awareness system must be established and enforced when created.
