OpenBSD's Packet Filter Gains OS Fingerprinting

Posted by CowboyNeal on from the no-more-amigas-on-my-networks dept.

basilpronoun writes "The PF packet filter / firewall that comes with OpenBSD has just been improved to allow firewalling decisions to take place based not only on the source of a connection, but the operating system of that source. There are both good and evil applications, not the least of which is blocking the spam from infected Windows machines."

    The scary thing is most of OHSU, including it's Oregon Graduate Institute of Technology and it's multiple medical research facilities, use Windows. Granted, when I need medical treatment, I'm not exactly going to be picky about those issues, but if they picked practically any other OS but Windows, it would save them the work of treating me for stomach irritation in addition to everything else.
