5 Key Requirements for PCI DSS Compliance: 4.0 Compliance Checklist

PCI DSS 4.0 is the exclusive update of the Payment Card Industry Data Security Standard. It is accomplished by the organizations that deal with! card exchanges and cardholders datasets. PCI DSS is led by PCI Standards Security Council, established by renowned card companies including Visa, Mastercard, American Express and Discover. PCI DSS 4.0 makes the usage, storage and transfer of cardholders’ data more safe and agile. It helps limit and completely removes the credit and debit cards data loss. PCI DSS arranges robust safety protocols for card users and merchants to safeguard card data and usage from data breaches and harmful attacks.

Following are the five main requirements that users should fulfil to extract the best uses of PCI DSS 4.0

● Installation and administration of a firewall

The first and foremost step towards maintaining organizational compliance in PCI DSS 4.0 is installing a firewall. There should be an adequate configuration of routers and firewalls to safeguard the cardholder’s data. Firewalls assist in adding security barriers to incoming and outgoing networks, further strengthening the card data. Organizations must incorporate robust firewalls that guard the entry and exits of accesses by filtering the unsolicited and harmful entries.

● Removing vendor default setting

The following essential requirement is eliminating the vendor default settings automatically installed on devices, systems and software. Generally, operating devices and panels have a username and password already set by the vendors. These usernames and passwords are vulnerable to foreign attacks. Whenever you incorporate PCI DSS 4.0, ensure that you alter the password and name and then use it.

● Securing stored cardholder data

Securing cardholder’s data is essential for completing PCI DSS 4.0 compliance. Users should know where the cardholder’s data is stacked, whether in documents, spreadsheets, or other files. Organizations should follow industry norms, algorithms and rules to protect the data. There are four ways of protecting cardholder’s data- encryption, truncation, masking, and hashing. Follow these rules and make the datasets confidential and safe from malicious users and attacks.

● Encryption of payment data transmission

Organizations should set stringent safety protocols on open and public networks to ensure the safe transmission of cardholder data. The primary payment gateways and processors should be appropriately encrypted. Using robust transmission protocols for encryption such as TLS and SSH helps safeguard the payment data transmission’s integrity.

● Regular maintenance of antivirus software

Antivirus protects cardholders’ datasets and crucial information portfolios from malware campaigns and unauthorized access. The proper deployment of antivirus protects data software, networks and computers from attacks of hacking, digital theft and data scraping. Make sure all the antivirus mechanisms are maintained and updated regularly.


These are the five essential requirements organizations must accomplish to ensure PCI DSS 4.0 compliance. Following the global standards of PCI DSS makes the storage, transmission and processing of card data effective and highly secure. Companies that deal with credit or debit cards data should precisely fulfil all these requirements. It will help them protect the customer’s data most plausibly.
