Laura Raderman
Laura's speaking skills bring together several topics surrounding security. Her specializations are network and UNIX security. She is also active in PKI development and management, like how to actually use those certificates you spent so much for.
Laura comes from a UNIX system administrator background, with fluency in OS X, FreeBSD, Linux (Debian and RedHat/Fedora), Solaris, and even some HP-UX and AIX thrown in.
Lately, she's been managing groups of security professionals for such tasks as defining requirements, developing secure code, and penetration testing.
Laura holds both CISSP and PMP certification as well as older Solaris system administration and networking credentials.
