Securing BGP

Thu, 03/10/2011 - 15:10 by Olivier Bonaventure • Categories:

BGP is one of the key protocols that are used on the Internet today. Despite of its importance, the security of BGP is still a concern. Several solutions to improve the security of BGP have been proposed by the research community :


TCP crypt

Despite its respectable age (the first specification was published in September 1981), TCP is still alive and researches and IETFers continue to develop new extensions to improve the protocol. Multipath TCP received a lot of attention during the last years. Another TCP extension to improve the security of TCP has been submitted for the next IETF meeting. TCP crypt aims at improving the security of TCP by allowing the utilisation of crypto mechanisms to protect the TCP segments.


Hijacking FON user's Facebook & Twitter sessions using firesheep

In the following video, we show that it is easy (i.e. anybody can do it) to hijack FON user's sessions (i.e. access his Facebook, Twitter,... accounts) using a simple Firefox extension. You simply have to be connected on the same access point, which is an open access point in the case of FON and most hotspots.

LAN Switch Security : What hackers know about your switches

Wed, 03/26/2008 - 21:48 by Olivier Bonaventure • Categories:

Ethernet is now the default fixed Local Area Network technology. Ethernet LANs are found in all entreprise environments and in more and more home networks. Ethernet was designed in the 1970s when security was not a concern. Since then, Ethernet has evolved with the introduction of hubs and switches. Many network administrators are aware that hubs are a security concern since they broadcast Ethernet frames and some of them assume that switches or more secure.
