A colleague pointed out the NSF-funded trust-HUB project to me last week: http://www.trust-hub.org/. trust-HUB, similar to CTSC's trustedci.org website, looks to build an online community working with hardware security and trust.
The GSI-OpenSSH team has published a security advisory than impacts deployments that have the PermitPAMUserChange feature enabled (by default it is disable). Default configurations of GSI-OpenSSH are not affected. For details, please seehttp://grid.ncsa.illinois.edu/ssh/pamuserchange-2013-01.adv
