REALITY: YOUR APPLICATIONS ARE USING IPV6 ALREADY -Linux, Mac OS X, BSD, and Microsoft Vista/Windows 7 systems all come with IPv6 capability, some even have IPv6 enabled by default (IPv6 preferred) -They may try to use IPv6 first and then fall-back to IPv4 -If you are not protecting your IPv6 nodes then you have just allowed a huge back-door to exist!
YOUR USERS ARE USING IPV6 ALREADY File: Secmyth1REALITY: IPSEC IS NOT NEW -IPsec exists for IPv4 -IPsec mandates in IPv6 are no guarantee of security IPv6 was designed 15-20 years ago Extension Headers File: Secmyth2 Header Type 0 (RH0) – Source Routing -Deprecated in RFC 5095: -The functionality provided by IPv6's Type 0 Routing Header can be exploited in order to achieve traffic amplification over a remote path for the purposes of generating denial-of-service traffic Hop-by-Hop Options Header -Vulnerable to low bandwidth DOS attacks -Threat detailed in draft-krishnan-ipv6-hopbyhop Extension Headers are vulnerable in general -Large extension headers -Lots of extension headers -Invalid extension headers Rogue Router Advertisements (RAs) -Can renumber hosts -Can launch a Man In The Middle attack -Problem documented in RFC 6104 -In this document, we summarise the scenarios in which rogue RAs may be observed and present a list of possible solutions to the problem Forged Neighbor Discovery messages ICMP Redirects – just like IPv4 redirects Many attacks are above or below IP -Buffer overflows -SQL Injection -Cross-site scripting -E-mail/SPAM (open relays) REALITY: Stateful Firewalls Provide Security -NAT can actually reduce security REALITY: SLAAC - EUI-64 addresses (well known OUIs) -Tracking!
) The goal of the IETF is to make the Internet work better.
The mission of the IETF is to make the Internet work better by producing high quality, relevant technical documents that influence the way people design, use, and manage the Internet. The Internet Engineering Task Force (IETF) is an organized activity of the Internet Society (ISOC).

The system includes one or more subsystems for providing trusted... Examples of such application programs with which the present invention may be used to assist in such digital document processing are Microsoft® Access 97, Microsoft® Excel 97, and Microsoft® Word 97, each available from Microsoft Corporation, Redmond, Wash. Two primary methods of digital communications among computers presently exist.
The site, a former waste oil recycling storage facility, accepted waste oil from a number of companies, including Alcoa. Funding staffing levels in California schools lag behind other states.
Southern Unionists were extensively used as anti- guerrilla forces and as occupation troops in the Confederacy occupied by the Union. All were supplied from the factory in barrel mount. Essentially, this reduced the National Register of Historic Places.
In the Macintosh environment in particular, a document is any user-created work named and saved as a separate file. Digital Communications “Communications” may be broadly defined as the vast discipline encompassing the methods, mechanisms, and media involved in information transfer.
Therefore, a database, a graphic, or a spreadsheet can all be considered as much a document as is a letter or a report.
