14 Recent Data Breaches Physical Impact Cyber Attack Caused Damage at German Steel Mill (January 8, 2015) A report released in mid-december disclosed that a cyber attack on a German steel mill caused damage to the facility. The attackers disrupted the plant's control system to make it impossible to shut down a blast furnace properly. The damage was described as "massive," but no details were provided. This is the second documented case of a cyber attack causing physical damage - the first was Stuxnet. The report said that the attackers gained initial foothold in the system through the corporate network and worked their way from there to the production systems Wired Magazine Jan. 8 article A Cyber Attack has caused confirmed physical damage for the Second Time Ever by Kim Zetter via Jan. 13 SANS Institute NewsBite

25 Attackers learning faster than Defenders In most cases, attackers needs hours to compromise (more then 75% of the cases) where the defenders rarely discover the compromise in less then months (only about 25% of the breaches are detected in days or less) More importantly, the attackers are getting better faster than the defenders are improving their skills and capabilities Verizon Data Breach Investigations Report (DBIR) 2014

30 Lessons Learned Boston Children s Hospital In reflecting on the Anonymous attack, the BCH CIO noted: Distributed Denial of Service (DDoS) countermeasures are crucial. BCH shut down all web-sites and . Staff communicated using a secure text messaging application the hospital had recently deployed. Know which systems depend on external Internet access. In BCH s event, the EHR system was spared, but the e-prescribing system wasn't Make no excuses when pushing security initiatives. Children's had to shut down , e-prescribing and external-facing websites quickly. Secure your teleconferences. Send your conference passcode securely, not in the body of your calendar invite. Separate signals from noise. CIO.com article Sep. 14,2014 How Boston Children s Hospital Hit Back at Anonymous

31 Lessons Learned Organizations need to increase their visibility into what's happening in their enterprises and focus on eliminating those cybersecurity blind spots," says Jason Mical, vice president of cybersecurity for AccessData. Many organizations simply don't have enough tech and security staff to notice these breaches when they occur Information Week Dark Reading Blog June 30, 2014

32 Risk Mitigation Best Practices 2014 CliftonLarsonAllen LLP

33 Overall Approach - TK 2 Train your people - Users and Executives who are knowledgeable and savvy Know your network Make your networks resistant to malware Segment your network Make it visible to Executive management Know your data - data first approach minimum necessary access are you a target

34 Kill Chain Method of Defense For Targeted Attacks Instead of installing static defense tools and waiting for the next attack, network defenders should continuously monitor their systems for evidence that attackers are trying to gain access to their systems. Defenders can use the intelligence they gather about an attacker s playbook to anticipate and mitigate future intrusions based on knowledge of the threat. When a defender analyzes the actions of attackers, finds patterns, and musters resources to address capability gaps, it raises the costs an adversary must expend to achieve their objectives... [and] such aggressors have no inherent advantage over defenders. Eric M. Hutchins, Michael J. Cloppert, Rohan M. Amin, Intelligence-Driven Computer Network Defense Informed by Analysis of Adversary Campaigns and Intrusion Kill Chains, Lockheed Martin (2011) (online at Paper-Intel-Driven-Defense.pdf)

35 Ten Keys to Mitigate Risks 1. Strong policies and training use, strong password requirements 2. Defined user roles and permissions minimum necessary 3. Hardened internal systems change default passwords, media limitations (CD, USB devices), disallow local admin rights on workstations

36 Ten Keys to Mitigate Risks 4. Encryption strategy mobile 5. Vulnerability management process patch and test 6. Well defined perimeter security layers: Know Your Network

37 Ten Keys to Mitigate Risks 7. Data classification strategies Know Your Data 8. Defined incident response plan and procedures 9. Centralized audit logging, analysis, and automated alerting capabilities 10. Test, Test, Test
