What must an organization regularly test as part of PCI DSS compliance?

An organization must regularly test its security systems and processes as part of PCI DSS (Payment Card Industry Data Security Standard) compliance to ensure that they adequately protect cardholder data. The PCI DSS establishes a framework for securing credit card transactions, requiring organizations that handle cardholder information to implement specific security measures.

Regular testing of security systems includes vulnerability scanning, penetration testing, and security assessments. These practices help identify weaknesses that could be exploited by attackers, ensuring that the organization can maintain the integrity, confidentiality, and availability of cardholder data. Compliance with PCI DSS not only protects customers' sensitive information but also reduces the risk of data breaches and the potential for financial loss or reputational damage.

Additionally, a continuous focus on security processes allows organizations to adapt to evolving threats and regulatory requirements, making this testing vital for maintaining compliance and safeguarding customer information.
