Kasirota enhanced the MicrosoftDocs/security repository by refining the Program Requirements documentation to clarify certificate revocation mechanisms for certificate authorities. Focusing on certificate management and documentation, Kasirota updated guidance to specify that OCSP is optional and provided recommendations for using CRLs, including considerations for list size when OCSP is unavailable. The work included updating date metadata to ensure documentation currency and maintain traceability. Using Markdown and leveraging expertise in security policy alignment, Kasirota’s contributions reduced ambiguity in CA certificate issuance workflows. The changes addressed operational clarity for CAs, supporting more secure and maintainable certificate management practices without introducing new code defects.
