Benefits of Risk
Assessment
•Identify areas where stored CHD is not fundamental to
business and can be removed
•Segmentation of sensitive CDE from non-sensitive parts
of the network
•Keep pace with changing business environment and
identify new threats
•Make decisions on future resource investments
•Most critical risks are addressed first

Risk Assessment and
the Prioritized Approach
• PCI DSS Prioritized Approach
– A series of 6 Milestones to help organizations pursuing PCI compliance for the first time
– Also relevant to PCI re-certifications, as business landscapes are subject to change over the year
• Milestone 1
– a formal risk assessment process is to be implemented to identify threats and vulnerabilities
Presented by www.sisainfosec.com and Free Formal Risk Assessment tool www.smart-ra.com
Continuous Risk
Assessment
• Keep up with changing business landscape
– New business processes, departments
– Acquisitions and mergers
– New ventures
• Accurate Identification of Entities
– Since data is appended to the RA as and when it is
available, the identification phase of the RA is done
accurately.
