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 cardholder’s 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.

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
cardholder’s 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

2. 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.
Conclusion
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.

3. 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.
