Checkout the videos from the recent 28C3 conference here, some great ones include:
- The Science of Insecurity – a great primer on why network/communication protocols are such frequent sources of vulnerabilities
- The Coming War on General Purpose Computing – The must see keynote by Cory Doctrow (if you watch only one, make it this one)
- Kaminsky’s TCP Black Ops – A long and rather windy talk but the best nugget (at least for me) was why ACLs aren’t worth much
- PLC vulns in prisons – Why prisons are (unsurprisingly) not as secure as we hoped they were
