News of security researcher Michael Lynn’s presentation on vulnerabilities in Cisco routers at the BlackHat security conference is being reported everywhere. Both Cisco and ISS (Lynn’s former employer) did everything they could to prevent the researcher from giving his presentation. In the end, Lynn quit his job at ISS so that he could go on with the presentation unencumbered. Bruce Schneier has a good summary of events and an explanation of why protecting full disclosure is so important if we’re serious about security.
