OLS meets regulatory compliance challenges by protecting access to sensitive data such as personal identity information, medical records, and national security data. OLS can store data of multiple levels of sensitivity in a single table. With data sensitivity labels such as “Top Secret:US:A” and “Confidential:NOFORN:C”, it controls access to information based on the user’s clearance level, accesses, and need-to-know. Enforcing mandatory access controls (MAC), it has passed the ISO 15408 Common Criteria EAL4+ evaluation.
