Enhancing Security Measures for Link-Local Communication

This draft proposes new ideas and methodologies to improve security in link-local communication using GSPD and GDOI extensions. It discusses adjacency control rules and presents manual and automatic protection techniques with precise rules allocation. The document aims to address common features among OSPF, PIM-SM, and RSVP while seeking collaboration to tackle adjacency control issues effectively. Future plans include exploring more on these issues and attending relevant workshops.

Presentation Transcript

  1. Link-local security J.W. Atwood, S. Islam, S. Maziar PIM Working Group 2008/03/11 bill@cse.concordia.ca

  2. draft-ietf-pim-sm-linklocal-03 • Minor changes • Added empty IANA Considerations • Additional author • Some housekeeping • New Stuff • Section 10 on “IPsec Protection Barrier and GSPD”

  3. Recent activity • (Not yet reflected in the draft) • We have a much better understanding of common features among OSPF, PIM-SM and RSVP •  an idea for extending GDOI for our use •  ideas on controlling adjacency

  4. Protection Rules • Manual • We give the SPD and SAD rules for the manual case • Automatic • Rules will be in the GSPD • SAD rules will be dynamically allocated • Precise rules will come once the adjacency model is determined

  5. SPD Table entry • To protect outgoing link-local packets

  6. SAD Table entries • To protect incoming link-local packets • If single shared key, lines 2-4 merge, with Remote address = “any”

  7. Plans • Complete the exploration of the adjacency control issues • Once the (sub-) problem of “adjacency control issues” is better understood, find the right partners to create a problem statement • Attend the “kmart” BOF • Key Management for Routing Protocols

  8. ..2 • Present needed extensions for GDOI (to the MSEC wg) and ask for interest • Extend the link-local Internet Draft to use these GDOI extensions (in PIM wg)

  9. Questions?
