Internetworking and Internet Protocols (Appendix 6A) IP Security Overview IP Security Architecture Authentication Header Encapsulating Security Payload Combinations of Security Associations Key Management | Chapter 6 IP Security Henric Johnson Blekinge Institute of Technology, Sweden Henric Johnson Outline Internetworking and Internet Protocols (Appendix 6A) IP Security Overview IP Security Architecture Authentication Header Encapsulating Security Payload Combinations of Security Associations Key Management Henric Johnson TCP/IP Example Henric Johnson IPv4 Header Henric Johnson IPv6 Header Henric Johnson IP Security Overview IPSec is not a single protocol. Instead, IPSec provides a set of security algorithms plus a general framework that allows a pair of communicating entities to use whichever algorithms provide security appropriate for the communication. Henric Johnson IP Security Overview Applications of IPSec Secure branch office connectivity over the Internet Secure remote access over the Internet Establsihing extranet and intranet connectivity with partners Enhancing electronic commerce security Henric Johnson IP Security Scenario Henric Johnson IP Security Overview Benefits of IPSec Transparent to applications (below transport layer (TCP, UDP) Provide security for individual users IPSec can assure that: A router or neighbor advertisement comes from an authorized router A redirect message comes from the router to which the initial packet was sent A routing update is not forged Henric Johnson IP Security Architecture IPSec documents: RFC 2401: An overview of security architecture RFC 2402: Description of a packet encryption extension to IPv4 and IPv6 RFC 2406: Description of a packet emcryption extension to IPv4 and IPv6 RFC 2408: Specification of key managament capabilities Henric Johnson IPSec Document Overview Henric Johnson IPSec Services Access Control Connectionless integrity Data origin authentication Rejection of replayed packets Confidentiality (encryption) Limited traffic flow confidentiallity Henric Johnson Security Associations (SA) A one way .
