Understanding PCI DSS & Its Importance
Before we dive into the intricacies of PCI gap assessments, it’s crucial to understand the foundation upon which they’re built: the Payment Card Industry Data Security Standard [PCI DSS].
What is PCI DSS?
PCI DSS is a set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment. These standards were created by major credit card companies to protect cardholder data & reduce fraud.
The twelve (12) Requirements of PCI DSS
The PCI DSS framework consists of twelve (12) high-level requirements:
- Install & maintain a firewall configuration
- Use & regularly update anti-virus software
- Protect stored cardholder data
- Transmission of cardholder encrypted data across networks
- Use & regularly update anti-virus software
- Develop & maintain secure systems & applications
- Access should be restricted to cardholder data by business need to know
- A unique IDshould be assigned to each person with computer access
- Restrict physical access to cardholder data
- All access to network resources & cardholder data should be tracked & monitored
- Regularly test security systems & processes
- A policy should be maintained that addresses information security for all personnel
Understanding these requirements is crucial for conducting an effective PCI gap assessment. The requirements in more detail:
- Install & maintain a firewall configuration: Firewalls act as the first line of defense against unauthorized access to your network. They must be properly configured & regularly updated to protect cardholder data.
