Cyber Security

  1. 1. INSTITUTE FOR CYBER SECURITY Cyber Security: What You Need to Know Rohit Srivastava http://cybertechsecurity.blogspot.com World-Leading Research with Real-World Impact! 1
  2. 2. INSTITUTE FOR CYBER SECURITY 99-1 Principle (Roughly) 99% of the attacks are thwarted by basic hygiene and some luck DO  Think before you click etcetera  Up-to-date anti-virus, firewall and site advisor BUT  Some new attacks may get through. However, attacker may only use your machine to attack others and not attack you per se.  Will not prevent data loss by merchants and other servers. However, still have safety in numbers. Attackers can steal a lot of account numbers but can exploit much fewer. 1% of the attacks are difficult and expensive to defend or detect For most individuals  We are simply not an attractive enough target. For the US Department of Defense and its contractors  A huge target. Current score: 50-1 in favor of attackers (roughly) For companies in less sensitive businesses  A serious threat to be taken seriously World-Leading Research with Real-World Impact! 2
  3. 3. INSTITUTE FOR CYBER SECURITY Weakest Link: Password Reset Typically done via secret questions and email to preferred email account  Mother’s maiden name?  Father’s middle name?  Favorite pet’s name?  etcetera  “As detailed in the postings, the Palin hack didn’t require any real skill. Instead, the hacker simply reset Palin’s password using her birthdate, ZIP code and information about where she met her spouse — the security question on her Yahoo account, which was answered (Wasilla High) by a simple Google search.” Password reset on preferred email account itself done via secret questions Conundrum  Real answers easy to remember but discoverable via Google  False answers hard to remember but safe from Google World-Leading Research with Real-World Impact! 3
  4. 4. INSTITUTE FOR CYBER SECURITY Crystal Ball: In the Year 2025 PRIVACY  Expectation (and delivery) of privacy is close to zero E-COMMERCE SECURITY  Close to perfect NATIONAL AND CORPORATE SECURITY  The nation-state threat should be better contained  The asymmetric non-nation-state threat will remain World-Leading Research with Real-World Impact! 4
  5. 5. INSTITUTE FOR CYBER SECURITY Crystal Ball: In the Year 2025 PAST, PRESENT  Cyber security is a young and immature field  The attackers are more innovative than defenders  Defenders are mired in FUD (fear, uncertainty and doubt) and fairy tales  Attack back is illegal or classified FUTURE  Cyber security will become a scientific discipline  Cyber security will be application and technology centric  Cyber security will never be “solved” but will be “managed”  Attack back will be a integral part of cyber security World-Leading Research with Real-World Impact! 5
  6. 6. INSTITUTE FOR CYBER SECURITY Cyber Security: Major Trends Security Objectives:  Black-and-white to shades of grey Attackers:  Innovative beyond belief Defenders:  Need new doctrine World-Leading Research with Real-World Impact! 6
  7. 7. INSTITUTE FOR CYBER SECURITY Cyber Security: Major Trends Security Objectives:  Black-and-white to shades of grey Attackers:  Innovative beyond belief Defenders:  Need new doctrine World-Leading Research with Real-World Impact! 7

  12. 12. INSTITUTE FOR CYBER SECURITY Attackers: Innovative Beyond Belief Major Innovations  Botnets  Robust underground economy and supply chain  Targeted attacks  Stealthy attacks Some Examples  Drive by downloads  Scareware  Doctored online statements  Long-lived stealth attacks Status  Attackers have sizable inventory of known but unused or rarely used tricks  Innovation will continue World-Leading Research with Real-World Impact! 12

  14. 14. INSTITUTE FOR CYBER SECURITY           Defenders: Need New Doctrine OLD: Cyberspace is a supporting infrastructure NEW: Cyberspace is a war-fighting domain on par with land, sea, air and space OLD: It’s all defense, no attack back or preemptive attack NEW: All’s fair in war OLD: Defend the entire network to the same degree NEW: Defend selectively and dynamically OLD: Blame and harass the end user NEW: The user is part of the solution OLD: Defend against yesterday’s attacks NEW: Be proactive, get ahead of the curve, future-proof World-Leading Research with Real-World Impact! 14
  15. 15. INSTITUTE FOR CYBER SECURITY Research Excellence       Secure Information Sharing Social Computing Security Cloud Computing Security Malware Mitigation Military Grade Security Infrastructure Assurance and Security 50+ people and growing A jewel in UTSA’s drive to tier I status Research Laboratories    FlexCloud: cloud platform FlexFarm: malware honeyfarm Community exercises: the real real-world Core Differentiators   We are the flagship for cyber security research at UTSA We are unique amongst the myriad academic cyber security centers in the country due to our demonstrable emphasis on real-world impact World-Leading Research with Real-World Impact! 15
