The constant evolution of technology and growing cyber threats have driven the need to keep security standards constantly updated. The Payment Card Industry Data Security Standard (PCI DSS) is a clear example of this, undergoing significant changes from version 3.0 to version 4.0. Let's compare these two versions and understand the main differences.
PCI DSS 4.0 vs. PCI DSS 3.0:
Focus on Continuous Approach:
PCI DSS 3.0: PCI DSS Version 3.0 already emphasized the importance of continuous compliance, but the approach was more focused for carrying out periodic evaluations.
PCI DSS 4.0: The new version takes this one step further by promoting an ongoing security mindset. This means that organizations not only conduct regular assessments, but also constantly monitor their infrastructures to detect and respond to threats in real time.
Flexibility and Customization:
PCI DSS 3.0: The previous version had more prescriptive requirements, with less room to adapt to individual organizations' needs.< /p>
PCI DSS 4.0: Version 4.0 offers more flexibility, allowing companies to implement security measures according to their own circumstances, without compromising data protection.
PCI DSS 3.0: While multi-factor authentication was highly recommended, it was not a mandatory requirement in version 3.0.
PCI DSS 4.0: Multi-factor authentication is now a requirement in certain high-risk scenarios, providing an extra layer of protection for customer transactions and information.
Top Management Involvement:
PCI DSS 3.0: The previous version mentioned the importance of top management commitment, but without much detail.
PCI DSS 4.0: The new version emphasizes clearly the role of leadership in promoting a safety culture, highlighting the importance of top management support for the successful implementation of safety measures.
