It is an implementing component of the National Strategy for Homeland Security and is complemented by a National Strategy for the Physical Protection of Critical Infrastructures and Key Assets. The purpose of this document is to engage and empower Americans to secure the portions of cyberspace that they own, operate, control, or with which they interact. Securing cyberspace is a difficult strategic challenge that requires coordinated and focused effort from our entire society, the federal government, state and local governments, the private sector, and the American people.National Strategy for the Physical Protection of Critical Infrastructures and Key Assets PresidentPresident | Vice President | First Lady | Mrs. Cheney | News & Policies | History & Tours | Kids | Your Government | Appointments | Contact | Text onlyVice PresidentFirst LadyMrs. CheneyNews & Policies History & ToursKidsYour GovernmentAppointmentsContactText only AccessibilityAccessibility | Search | Privacy Policy | HelpSearchPrivacy PolicyHelp Mr. John L.

12. Security History (Network) None (we are all friends) – Early Internet users were researchers – Personal Computing revolution had yet to start 1988: Uh Oh! – Internet Worm, first time Internet made television... in a bad way Today – Security threats abound, but security technology is an add-on

13. Security is not Deployed Internet is “edge” centric –Hard to add security in the middle –Firewalls attempt to add security “quasi” edge Security is Hard –It is a “negative deliverable”  You don’t know when you have it, only when you have lost it!  Users don’t ask for it, so the market doesn’t demand it

20. IPsec Protects all upper-layer protocols. Requires no modifications to applications. –But smart applications can take advantage of it. Useful for host-to-host, host to gateway, and gateway-to-gateway. –Latter two used to build VPNs.

21. Doesn’t IPsec work with IPv4? Yes, but… It isn’t standard with v4. Few implementations support host-to-host mode. –Even fewer applications can take advantage of it.

22. No NATs NATs break IPsec, especially in host- to-host (P2P) mode. With no NATs needed, fewer obstacles to use of IPsec. Note carefully: NATs provide no more security than an application-level firewall.

25. Several choices for configuring the interface ID of an address: –manual configuration (of interface ID or whole addr) –DHCPv6 (configures whole address) –automatic derivation from 48-bit IEEE 802 address or 64-bit IEEE EUI-64 address –pseudo-random generation (for client privacy) the latter two choices enable “serverless” or “stateless” autoconfiguration, when combined with high-order part of the address learned via Router Advertisements Link-Local Site-LocalGlobal Configuring Interface IDs

26. IPv6 includes non-global addresses, similar to IPv4 private addresses (“net 10”, etc.) a topological region within which such non-global addresses are used is called a zone zones come in different sizes, called scopes (e.g., link-local, site-local,…) unlike in IPv4, a non-global address zone is also part of the global addressable region (the “global zone”) => an interface may have both global and non-global addresses Link-Local Site-LocalGlobal Non-Global Addresses

30. Recommendations of ISOC/IAB/IETF INET 2002 June 19 - while export controls have loosened, Cisco and others are still forced to distinguish between US and non-US versions of code, around crypto. It was suggested that USG simply drop all export restrictions on crypto code using the new Advanced Encryption Standard - we still don't know how to deploy a global Public Key Infrastructure, making global IPSEC privacy/authentication difficult (research funding) - ditto secure/scalable/quickly-converging global and local routing - ditto on intrusion detection as a service provider service (detecting and mitigating attacks of various kinds) Richard Clarke

33. Conclusions IPv6 mandates and enables an important improvement in security. Much of the improvement comes from standard, usable, IPsec. The very large address space may provide for other, innovative security mechanisms.
