Overview
ISO/IEC 10164-9:1995/Cor 2:1999 is Technical Corrigendum 2 to the ISO/IEC 10164-9:1995 standard (aligned with ITU‑T Rec. X.741). It provides editorial and syntactic corrections to the published specification for Open Systems Interconnection (OSI) Systems Management - objects and attributes for access control. The corrigendum clarifies ASN.1 module names, object/attribute identifiers, conditional presence markers, import statements and other notation issues to ensure unambiguous, interoperable implementations of OSI access-control information models.
Key Topics
- ASN.1 module and identifier corrections
- Renames modules (e.g., AccessControlDefinitions → AccessControl‑ASN1Module) and fixes object names (e.g., denyAccess → deny).
- Syntax and notation fixes
- Corrects ASN.1 CHOICE syntax, AE-title references, PRESENT IF conditionals, tab/whitespace errors and punctuation; addresses derived-from references.
- Package and registration updates
- Adjusts CONDITIONAL PACKAGE and PACKAGE terminators, REGISTERED AS object identifiers and package naming to match registration conventions.
- Import and reference clarifications
- Updates IMPORTS (e.g., AE‑title from ACSE‑1), adds explanatory ASN.1 comments about DistinguishedName sources (X.501/ISO‑IEC 9594‑2 and X.711/ISO‑IEC 9596‑1).
- Editorial consistency
- Standardizes parameter, filter and attribute names (case, hyphenation, commas) and fixes formatting errors that could affect parser or compiler behavior.
Applications
- Implementers of OSI systems management software and tools who rely on the access-control object model for authorization, auditing and configuration.
- Developers maintaining ASN.1 schemas, protocol stacks or management agents that must conform to ISO/IEC 10164‑9 / ITU‑T X.741.
- Security architects and integrators ensuring interoperable access-control attributes and operations across OSI-based network management systems.
- Standards bodies and test labs that verify conformance to the OSI systems management information model.
Who Uses This Standard
- Network and systems management engineers working with OSI protocols.
- Protocol implementers and ASN.1 tool vendors.
- Conformance test organizations and interoperability labs.
- Organizations maintaining legacy OSI-based management frameworks or migrating between standards.
