What is PCI DSS Compliance?

There are many international regulations that your organization needs to be compliant with besides PCI DSS compliance, including HIPPA, GDPR, NIST, ISO 27001, and Sarbanes-Oxley (SOX).

Twelve requirements for ensuring a secure network are:

1. Installing and maintaining firewalls. Firewalls scan network traffic and keep untrusted traffic out of your network perimeter.
2. Changing default passwords and other default settings. Default passwords are publicly obtainable and can easily be used to gain unauthorized access.
3. Protecting cardholder data. Protect cardholder data using methods such as encryption, hashing, masking and truncation.
4. When transmitting over public networks, transmission of cardholder data should be encrypted. Using trusted keys and certificates, as well as strong encryption, reduces the risk of being targeted.
5. Protecting against malware and updating anti-virus software.
6. Developing and maintaining secure systems and applications. Vulnerabilities allow bad actors to gain privileged access.
7. Restricting access to cardholder data to only authorized personnel.
8. Identifying and authenticating access to system components. Everyone who can access system components should have a unique identification which ensures accountability and tracks who has access to critical systems.
9. Restricting physical access to cardholder data. Physical access to cardholder data or systems that hold this data must be secure and inaccessible to those who do not have a “need to know.”
10. Tracking and monitoring who accesses cardholder data.
11. Regularly testing security systems and processes. There are always new vulnerabilities, which need to be discovered.
12. Maintaining an information security policy. An example of an infosec policy is set out in the NIST standards and cybersecurity framework as well as ISO 27001 controls.

According to the PCI Security Standards Council:

1. Change the default password
2. Restrict both inbound and outbound traffic to your payment system to the minimum necessary
3. Avoid “ANY” rules
4. “DENY ALL” traffic that is not explicitly authorized.
5. Permit only “established” connections into your network (for example, via packet inspection or packet filtering.)
6. Turn on isolation detection and intrusion blocking
7. Turn on notifications
8. Turn on NAT to hide your internal addresses from the Internet
9. Install firewall updates and patches as soon as they are available.

Many steps are involved in validating PCI DSS compliance. An assessment includes a Qualified Security Assessor (QSA), Internal Security Assessor (ISA), Report on Compliance (ROC), Self-Assessment Questionnaire (SAC).

AlgoSec automatically generates pre-populated, audit-ready compliance reports for PCI DSS as well as other leading industry regulations, including NIST SP 800-53, NIST SP 800-41, SOX, GLBA, and ISO 27001— which helps reduce audit preparation efforts and costs. AlgoSec also uncovers gaps in organization’s compliance posture and proactively checks every change for compliance violations. AlgoSec also provides daily audit and compliance reporting across the entire heterogeneous network estate. PCI DSS requirements are compared to the network security infrastructure, so get an accurate picture of your compliance status as well as any gaps.
