Los Alamos National Lab (LANL) Recent Top Innovations Cyber Security Experience Impenetrable encryption prevents data from cyber terrorism ► ► National Security Laboratory ► Focused on security science to National Multipronged HIV vaccine shows promise in monkeys ► protect the nation ► Long history of networking Tree death worldwide linked to warming climate ► ► First connected to Arpanet in 1983 ChemCam inspects Mars: can it support life? ► ► Long history of cyber security ► First attack in 1983 Roadrunner firsts pave way for more powerful supercomputing ► ► Over 15 years of data collected ► Many nation state and criminal Space probes predict hazards to protect spacecraft ► attacks ► Long history of cyber R&D Portable laser tool to thwart nuclear smugglers ► ► For defense of LANL’s network and US DOD networks RAPTOR telescope witnesses black hole birth ► ► Strong analytics program Liquid-scanning technology boosts airport security ► Improved biofuel methods: may be greener, cheaper yet powerful ► Page 3

History of our work From Government Research to Commercial Application 2011 : PathScan 2000 : and 2015 : LANL data CodeVision Commercial science for 2013 : RFP for deployment go live on LANL’s national proposals to and further security network commercialize development 2007 : 2012 : Other 2014 : EY Begin USG wins rights, enterprise deployments team security moves to analytics EY from research LANL Page 4

Signatures and Rules Traditional Cyber Security is not Statistical ► Rules and signatures ► Network IDS Example: If {bytes leaving network > X MB}, set off alarm If X is too large, easy to get around ► If X is too small, affects usability of the network ► ► Antivirus Example: If {executable contains known malware string}, set off alarm Requires having seen the malware before! ► Very easy for attackers to make new 0-day malware ► ► These brittle approaches are the reason we have so many breaches today Page 6
