  1. 양 수 미 정보보호 관련 표준

  2. 차례 • IETF 표준 • ISO/IEC JTC1 표준 • SC27 • SC27 이외 • ITU-T 표준

  3. IETF 표준 • IETF (Internet Engineering Task Force)의 IESG (Internet Engineering Steering Group) 내의 Security Area에서 제정한 표준들로 여러 Working Group에서 연구/제정된다. • It is established to support internet protocol engineering and development tool at 1986 under the ISOC( internet society).

  4. IETF (Internet Engineering Task Force) 의 주요한 목표는 인터넷의 운영상, 기술상의 문제점을 해결하기 위하여 프로토콜 및 구조에 대한 표준을 제안하고 개발 하는 것

  5. Internet standards and RFCs • The Internet society • IAB (Internet Architecture Board) : responsible for defining the overall architecture of the Internet, providing guidance and broad direction to the IETF • IETF (Internet Engineering Task Force) : The protocol engineering and development arm of the Internet ,비영리 단체인 IAB(Internet Archetecture Board)의 하위 조직. TCP/IP와 인터넷에 관한 정책과 표준안 작성을 담당 • IESG (Internet Engineering Steering Group) : responsible for technical management of IETF activities and the Internet standards process Henric Johnson

  6. IETF 표준화 과정 • Standard development stages • Internet drafts : they are on working documents for RFC(request for comments), register on directory during 6M. • Proposed standard : implement and test protocol( 6M-2Y) • Draft standard : at least 2 independent and interoperated products, need more field test on different wide environments( 4M-2Y) • Internet standard : successfully implemented operated protocol

  7. GENERAL area • APPLICATIONS area • INTERNET area • OPERATIONS and MANAGEMENT area • REAL-TIME APPLICATIONS and INFRASTRUCTURE area • ROUTING area • SECURITY area • TRANSPORT area

  8. Working Groups-1 • BTNS : IPsec/IKE(Internet Key Exchange) 관련 • DKIM : Domain Keys Identified Mail • EMU : EAP(Extensible Authentication Protocol) Method 관련 • HOKEY : 무선 Handover Keying • ISMS : SNMP 보안 관련, 인증.. • KEYPROV : 대칭키 관련 • KITTEN:GSS(Generic Security Services)-API개발 • KRB-WG : Kerberos 관련

  12. ISO/IEC JTC1 표준 • ISO( International Organizaton for Standardization)/ IEC(International Electronical Commission)JTC(Joint Technical Committee) 1 • A combined organization ( ISO/TC97 : information processing system fields and IEC/TC 83 : information equipments) • 정보처리시스템에 대한 국제표준화 활동과 정보기기에 대한 국제표준화 활동을 통합하여 구성된 정보기술분야의 국제표준화 활동을 위한 공동기술위원회 • SC20( data cryptographic techniques) was expended into SC27( security techniques).

  13. ISO/IEC JTC1 표준 • Standard development stages • Preliminary stage : preliminary work item (PWI) • Proposal stage : new work item proposal ( NP) • Preparatory stage : working drafts (WD) • Committee stage : committee drafts (CD) • Enquire stage : enquire drafts i.e. draft international standard (ISO) (DIS), committee draft for vote(IEC) (CDV) • Approval stage : final draft international standard (FDIS) • Publication stage : international standard(ISO,IEC,ISO/IEC)

  14. ISO/IEC JTC1 표준 • SC27 : IT Security techniques • IT 보안에 관한 일반적인 방법과 기술에 대한 표준을 주로 연구/제정한다. • 응용에 보안 메커니즘을 삽입하는 것을 제외한 정보기술 보안을 위한 일반적 방법과 기술에 대한 표준화 • 암호화 알고리즘의 표준화, 정보기술 시스템 보안 서비스를 위한 일반적 요구 명세, 보안 기술 및 메커니즘 개발, 문서 및 표준을 지원하는 관리 개발을 포함 • SC27이외

  15. SC27 이외

  16. ISO/IEC 13335-1:2004 • Information technology -- Security techniques -- Management of information and communications technology security -- Part 1: Concepts and models for information and communications technology security management • ISO/IEC 13335-1:2004 presents the concepts and models fundamental to a basic understanding of ICT security, and addresses the general management issues that are essential to the successful planning, implementation and operation of ICT security. Part 2 of ISO/IEC 13335 (currently 2nd WD) provides operational guidance on ICT security. Together these parts can be used to help identify and manage all aspects of ICT security.

  17. ISO/IEC 27002:2005(2007) • BS 7799:1999으로부터 발전 -> 17799 -> 27002 • 12 main sections • Risk assessment • Security policy - management direction • Organization of information security - governance of information security • Asset management - inventory and classification of information assets • Human resources security - security aspects for employees joining, moving and leaving an organization • Physical and environmental security - protection of the computer facilities • Communications and operations management - management of technical security controls in systems and networks • Access control - restriction of access rights to networks, systems, applications, functions and data • Information systems acquisition, development and maintenance - building security into applications • Information security incident management - anticipating and responding appropriately to information security breaches • Business continuity management - protecting, maintaining and recovering business-critical processes and systems • Compliance - ensuring conformance with information security policies, standards, laws and regulations
