Techopedia Explains Qualified Security Assessor

Security consultants and audit professionals are often the recommended candidates for a qualified security assessor program. They can be certified and recertified by attending the training provided by the payment card industry along with passing the certification exam. A QSA undergoing a recertification needs to pursue additional continuing professional education, which can be obtained from other work experiences and training.

A QSA needs to provide merchants with onsite data security assessments, gap analysis, payment card industry consultation and must give advice including remediation services, if needed. A QSA needs to understand the different aspects of an organization’s infrastructure including virtual network segmentation, surrounding physical information technology controls, virtualization-specific controls, etc.

Using a QSA could prove expensive and could be less economical than using internal security resources. However, a third-party validation can help in assessing the key areas and controls that could be missed out and can also provide the necessary diligence needed. A QSA can also help an organization meet all the requirements provided by the payment card industry. In this case, the internal resources of an organization need not be diverted from other projects.
